Description

Detailed Description of the Invention (Industrial Application Field 9) This invention relates to a medical bed used for ultrasonic diagnosis of the heart, and particularly relates to a medical bed used for ultrasonic diagnosis of the heart. The present invention relates to a medical bed that can be obtained.

(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 is capable of accurately diagnosing the internal structure of the heart. Therefore, recently, instead of such a method, an ultrasonic diagnostic apparatus using ultrasonic waves has 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 air contained there seriously impedes the resolution performance for understanding the internal structure of the heart. On the other hand, patients undergoing ultrasound diagnosis have a variety of body shapes depending on age, gender, etc., and if the distance between the chest wall and the heart is long due to individual differences in the chest, the beam reach distance may deviate from the one allowed for resolution performance. There's something to do. Therefore, in the past, patients who had to lie down on a bed had to move on their own on the bed and tilt their upper body to reduce the distance between the chest wall and the heart, or it was painful for them to move their upper body and keep it in a tilted position. However, there was a problem in that it was difficult to obtain a precise image of the internal structure of the heart, especially over a long period of time.

The probe is connected to the main body of the ultrasound diagnostic apparatus by a cord, and is held by the examiner's hand during heart examination.
e. It is painful for the examiner to contact the skin surface of the person's chest or maintain that position for a long time, and sometimes the position of the probe is blurred, making it difficult to accurately determine the precise internal structure of the heart. The problem was that it was difficult to do so.

(Means for Solving the Problems) Therefore, the present invention has been made by focusing on such conventional problems. The movable floor part 3 is divided into a floor part 2 and a movable floor part 3 on which the upper half of the body lies, and this movable floor part 3 is further divided into two in the transverse direction into a tilting part 5 and a supine part 6. It is movable in order to raise only the patient's upper body side together with the supine part 6, and can be tilted 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 supine position. A reinforcing frame provided below the fixed bed section 2 is provided with a probe support that allows one end of the probe 25 to come into contact with the skin surface of the patient who is placed in the left lateral decubitus position. To provide a medical bed, in which a rod is fixed so as to be bendable, and a finger ring 26 is provided on the movable floor part 3 to prevent a patient who is placed in a left lateral decubitus position from falling off the bed. The purpose of this invention is to improve the resolution performance 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 implemented will be explained along with its operation with reference to the drawings.

As shown in FIG. 1, the movable floor section 3 is further divided into a tilting section 5 and a supine section 6 in the transverse direction, and both the tilting section 5 and the supine section 6 are raised from a horizontal position. At the same time, the tilting section 5 is configured to be biased toward the left supine section 6, that is, tilted in a direction perpendicular to the longitudinal direction of the head 1.

The mechanism for raising the tilting part 5 and the supine part 6 will be explained according to FIG. 2. The movable floor part 3 has a pair of opposing side frames 7a
, 7b, and connecting frames 7c, 7a connecting the side frames 7a, 7b are placed on the movable floor support frame 7, which is formed into a rectangular shape. The tip of the side frame 7a of the movable floor support frame 7 is on one end of the side frame 4a of the fixed floor support frame 4, and the tip of the side frame 7b of the movable floor support frame 7 is on the side of the fixed floor support frame 4. Frame 4
The movable floor support frame 7 is pivotally supported at one end of each movable floor support frame 7, and is movable up and down with respect to the fixed floor support frame 4 about a pivot shaft 8.9.

A lifting device 10 is used to raise and lower the movable floor support frame 7, and the lifting device 10 includes a support cylinder 11 having a female thread carved on its inner peripheral surface, and a screw thread between the female thread and the support cylinder 11. The support tube 11 is fixed to the connecting frame 4C of the fixed floor support frame 4, and has a handle 13 at one end.
is attached. The other end of the movable rod 12, whose bent end is screwed into the other end of the support tube 11, is fixed to a support piece 14 that is suspended from the connecting frame 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 support frame 7, and the tilting part 5 of the movable floor part 3 is placed on this tilting part support frame 15. The supine part 6 is placed on the left half of the body 7. [Tilt part support frame] 5 is the frame 15a on both sides thereof.

One end of 15b is the side frame 7c of the movable floor support frame 7.

7d, and can be tilted to the left, that is, in the direction of the supine portion 6, about the pivot shafts 16a, 16b.

A tilting device 17 is used to tilt the tilting portion support frame 15.
The tilting device 17 has substantially the same structure as the lifting device 10, and includes a support tube 1 having a female threaded portion on the inner peripheral surface.
8 and a movable rod 19 that has a male threaded portion on its outer circumferential surface that engages with this female threaded portion and extends and retracts within the support tube 18, and the support tube 18 is fixed to the side frame 7b of the movable floor support frame 7. ,
A handle 20 is attached to one end of the handle. One end of the movable rod 20 is screwed onto the inner peripheral surface of the other end of the support tube 18, and the other end of the movable rod 19 is suspended from the side frame 15C of the tilting portion support frame 15. It is fixed to the support piece 21. 22a, 22b, 22C and 22d are the legs of the head 1, and between the legs 22a and 22c there is a reinforcing frame 23a or
A reinforcing frame 23b is interposed between the legs 22C and 22d. A probe support rod 24 is fixed to this reinforcing frame 23G. The probe support rod 24 is composed of a base end 24a (!:) whose one end is fixed to the reinforcing frame 23a, and a bellows-shaped bent part 24b formed at the tip of the base end 24a. As shown in Fig. 5, this bent part 24b can be freely bent 360 degrees as shown by the arrow, and can also be fixed at any position. The probe 25 is detachably attached.The probe support rod 24 is attached to the reinforcing frame 2.
3a, or may be fixed to the reinforcing frame 23b, which is not necessarily limited to this.

Further, as shown in FIG. 2, an inverted U-shaped handle ring 26 is fixed to the movable floor support frame 7 of the movable floor 3. As shown in FIG. As shown in FIG. 4, this handle ring 26 is designed so that the tilting part 5 of the movable floor part 3 is tilted so that the upper body side of the patient is placed on the supine part 6t.
This is to prevent the patient from falling off the medical bed 1 by holding the handle ring 26 with his/her hand when the patient is forced to deviate from the medical bed 1.

Next, to explain the operation of the medical bed 1 having the configuration shown in Part 2 above, first, the movable floor part 3 is brought down and adjusted to the same plane position as the fixed bed part 2, that is, the horizontal position, and then the patient is placed on the medical bed 1.
Have the patient lie down. After lying down on the patient or medical bed 1,
When the handle 13 of the lifting device 1o is rotated to the right, that is, clockwise, the movable rod 12 extends from the support tube 1] while being screwed into the support tube 11, and when the movable rod 12 extends, the tip of the movable rod 2 The movable floor support frame 7, which is fixed to the floor, rises about the pivot shafts 8a and 8b as shown in FIG.

Next, when the handle 20 of the tilting device 17 is rotated to the right, that is, clockwise, the movable rod 19 of the tilting device 7 extends from the support tube 18 while being threadedly engaged with the support tube 18.
When extended, the tilting part support frame 5 fixed to the distal end of the movable rod 19 is tilted 1ζ upward, that is, toward the supine position 6, as shown in FIG. By tilting the tilting part support frame 5, 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 60 degrees to the left side. The patient is forced to lie down.

In this case, the patient grasps the handle ring 26 with his/her hand to prevent the patient from falling off the medical bed 1.

As a result of the patient's upper body being shifted 60 degrees to the left side, 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 thorax, which has been biased, to perform a cardiac examination. At this time, the probe 25 is attached to a freely bendable probe support rod 24. Therefore, probe 2
5 can be touched at any position on the skin surface of the chest.

When the heart examination is completed in this way, the tilting device 17
When the handle 20 is completely rotated to the left, that is, counterclockwise, the movable rod 19 is compressed into the support tube 18 while being screwed into the inner peripheral surface of the support tube l8, and when the movable rod 19 is contracted, it is tilted. The part support frame 15 returns to the horizontal position, and the tilting part support frame 1
5 is housed in a movable floor support frame 7. Next, the lifting device 1
When the handle 13 of 0 is rotated to the left, that is, counterclockwise, the movable rod 12 is screwed into the inner circumferential surface of the support tube 1 and contracted into the support tube. The movable floor support frame 7, which had been in the horizontal position, is lowered and returned to the horizontal position.

(Effects of the present invention) According to the present invention, the head is divided into two parts, a fixed floor part and a movable floor part ♂, and this movable floor part can be raised and lowered freely. 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, so that the heart is closer to the left side, the distance between the heart and the chest wall is closer, and ultrasound waves can more easily reach the heart. As a result, better resolution can be obtained.

Furthermore, we provided a probe support rod to which the probe is attached, so
During ultrasound diagnosis, the examiner no longer needs to hold the probe and touch the skin of the chest, reducing the burden on the examiner and reducing the risk of the probe rubbing against the skin of the chest. This allows the probe to contact the skin surface accurately.

Furthermore, since the probe support rod is formed to be bendable, the probe can be conveniently brought into contact with the skin surface without moving the probe to an arbitrary position on the skin surface.

In addition, since a handle ring is provided on the movable bed, there is an advantage that even if the patient is shifted to the left lateral position, by grasping the handle ring, the patient will not fall out of the head.
