Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a medical bed used for ultrasonic diagnosis of the heart, and in particular, it makes it easier for ultrasonic waves to reach the heart to obtain better resolution. This is related to medical beds.

(Prior Art) Conventionally, heart diagnosis has been carried out by listening to the heartbeat using a hearing instrument or by examining X-rays, but neither of these methods allows accurate diagnosis of the internal structure of the heart. Therefore, in place of such a method, ultrasonic diagnostic equipment has recently become popular. By using this ultrasound diagnostic device,
The internal structure of the heart can be clearly seen without causing pain to the patient, contributing to cardiac diagnosis.

(Problem to be solved by the invention) By the way, in order to know the internal structure of the heart using such an ultrasound diagnostic device, it is necessary to touch the probe attached to the ultrasound diagnostic device to the skin surface of the patient's chest. It is necessary to.

However, the chest wall and lungs are interposed between the probe that comes into contact with the skin surface and the heart, and the heart is contained therein. Air seriously interferes with the resolution of the internal structure of the heart. On the other hand, patients undergoing ultrasound diagnosis have a variety of body shapes depending on their age, gender, etc., and if the distance between the chest wall and the heart is long due to individual differences in the thorax, the beam reach distance may deviate from the one allowed for resolution performance. There are things to do. Therefore, conventionally, patients lying on the bed would move on their own on the bed and tilt their upper body side to reduce the distance between the chest wall and the heart.
It is painful to move the upper body side and keep it in an inclined position, and it is especially difficult for long periods of time, making it impossible to obtain precise resolution of the internal structure of the heart.

Furthermore, the probe is connected to the main body of the ultrasound diagnostic equipment by a cord, and during cardiac examination, the examiner holds it in his/her hand and contacts the skin surface of the patient's chest, but the probe does not remain in that position for a long time. This is painful for the examiner, and sometimes the position of the probe may shift, making it difficult to accurately determine the precise internal structure of the heart.

(Means for Solving the Problems) Therefore, the present invention has been made by focusing on such conventional problems. A floor section 2 and a movable floor section 3 on which the upper body side lies
This movable floor part 3 is further divided into two in the transverse direction into a tilting part 5 and a supine part 6, and the tilting part 5 is designed to raise only the upper body side of the patient together with the supine part 6. It is formed so as to be able to rise and fall freely and tilt toward the supine part 6 in a direction perpendicular to the longitudinal direction in order to bias the patient's upper body side to the left side decubitus position, and is provided below the fixed bed part 2. A probe support rod 24 is bendably fixed at one end of the reinforcing frame so that one end of the probe 25 can come into contact with the skin surface of the patient who is shifted to the left lateral position. The object of the present invention is to provide a bed for improving the resolution of the internal structure of the heart when examining the heart using an ultrasonic diagnostic apparatus, thereby solving the above-mentioned problems.

(Example) Hereinafter, how the configuration of the present invention is actually embodied will be explained with reference to the drawings, together with its operation.

FIG. 1 is a perspective view of the entire medical bed. This medical bed 1 is divided into two in the longitudinal direction into a fixed bed section 2 on which the patient's lower body lies and a movable bed section 3 on which the patient's upper body lies. Ru. This fixed floor part 2

The support tube 11 is fixed to the connecting rod 4c of the fixed floor support frame 4, and a handle 13 is attached to one end thereof. It is set up. The other end of the movable rod 12, one end of which is screwed into the other end of the support cylinder 11, is fixed to a support piece 14 that is suspended from the connecting rod 7d of the movable floor support frame 7.

A rectangular tilting part support frame 15 is housed in the right half of the movable floor part support frame 7, and this tilting part support frame 1
The tilting section 5 of the movable floor section 3 is placed on the movable floor section 5, and the supine section 6 is placed on the left half of the movable floor support frame 7. The tilting part support frame 15 has both side frames 15a,
One end of 15b is the side frame 7c of the movable floor support frame 7,
7b, and can be tilted to the left, that is, in the direction of the supine portion 6, about the pivot shafts 16a, 16b.

A device for tilting the tilting portion support frame 15 is a tilting device 17, which has substantially the same structure as the elevating device 10, and includes a support cylinder 18 having a female threaded portion on its inner circumferential surface. It is composed of a movable rod 19 that has a male threaded portion on its outer circumferential surface that engages with a female threaded portion, and that extends and retracts within the support tube 18. The support tube 18 is fixed to the side frame 7b of the movable floor support frame 7, and A handle 20 is attached to one end. One end of the movable rod 20 is screwed onto the inner peripheral surface of the other end of the support cylinder 18, and the other end of the movable rod 19 is suspended from the side frame 15c of the tilting portion support frame 15.

3b.

Next, to explain the operation of the medical bed 1 having the above structure, first, the movable floor section 3 is laid down and adjusted to the same plane position as the fixed floor section 2, that is, the horizontal position.
The patient is made to lie down on a medical bed 1. After the patient lies down on the medical bed 1, when the handle of the elevating device 10 is rotated to the right, that is, clockwise, the movable rod 12 is screwed into the support tube 11, and the support tube 11
When the moving rod 12 extends, the moving rod 1
The movable floor support frame 7 fixed to the tip end of the movable floor support frame 7 rises about the pivot shafts 8a and 8b as shown in FIG. Next, the handle 2 of the tilting device 17
0 to the right, that is, in the clockwise direction, the movable rod 19 of the tilting device 17 extends from the support tube 18 while being screwed into the support tube 18, and when the movable rod 19 extends, it is fixed to the tip of the movable rod 19. The tilting part support frame 15 that is in the position is raised, that is, tilted toward the supine part 6, as shown in FIG. By this tilting of the tilting part support frame 15, the tilting part 5 of the movable floor part 3 placed on the tilting part support frame 15 is tilted toward the supine part 6, and the patient's upper body side is about 60 degrees to the left. The patient is forced to lie down.

As a result, the heart moves to the left side, and the distance between the heart and the chest wall becomes closer, making it easier for ultrasound waves to reach the heart.

The probe 25 is then brought into contact with the skin surface of the patient's chest that has been biased in this way to perform a cardiac examination. At this time, the probe 25 is attached to a freely bendable probe support rod 24. Therefore, the probe 25 can be brought into contact with any position on the skin surface of the chest. When the heart examination is completed in this way, when the handle 20 of the tilting device 17 is rotated to the left, that is, counterclockwise, the movable rod 19 is screwed into the inner peripheral surface of the support tube 18 and When the movable rod 19 contracts, the tilting part support frame 1
5 returns to the horizontal position, and the tilting part support frame 15 is housed in the movable floor part support frame 7. Next, when the handle 13 of the lifting device 10 is rotated to the left, that is, counterclockwise, the movable rod 12 is screwed into the inner peripheral surface of the support tube 11 and contracted into the support tube 11, and when the movable rod 12 is contracted, The movable floor support frame 7, which had been raised, will be lowered and returned to the horizontal position.

(Effects of the present invention) According to the present invention, the bed is divided into two parts, a fixed bed part and a movable bed part, and the movable bed part is made up and down freely, so that the patient can move his/her body without moving his/her body. Ultrasound diagnosis becomes possible, making it easier for patients.

In addition, this movable floor part is further divided into two parts, and the tilting part can be tilted toward the supine part.
As the heart moves to the left side, the distance between the heart and the chest wall becomes closer, making it easier for ultrasound waves to reach the heart, resulting in better resolution.

Furthermore, since we have provided a probe support rod on which the probe is attached, there is no need for the examiner to hold the probe in his hand and make contact with the skin surface of the chest during ultrasound diagnosis.
The load on the examiner is reduced, and there is no fear that the probe will shift from the skin surface of the chest, allowing the probe to come into accurate contact with the skin surface.

Furthermore, since the probe support rod is formed to be bendable, it is possible to move the probe to any position on the skin surface, which has the advantage of being convenient for contacting the probe with the skin surface. be.
