Description

Technical Field

[0001] The invention relates to the field of transport equipment for transporting patients, and in particular to a lithotomy position device. Background Art

[0002] In clinical medical treatment, lithotomy position is a commonly used body position. The lithotomy position refers to the patient lying on his back with his legs placed on a leg rest to expose the perineum to the maximum extent. It is often used in obstetrics and gynecology examinations, operations, and anorectal surgery. In some cases, the patient needs to be transferred while maintaining the lithotomy position. For example, in the preparation room of the hospital, the patient needs to lie on a special lithotomy transfer bed to maintain the lithotomy position, and then be transferred to the treatment room or operating room for corresponding treatment.

[0003] like Figure 1 The lithotomy position transfer bed 1 in the prior art shown in the figure comprises a bed frame 2, on which a transfer bed plate 3 is detachably fixed, and on which a leg rest 22 is fixed. The patient lies on the transfer bed plate 3, with his legs spread apart and fixed on two leg rests 22, and is transferred in the lithotomy position. This lithotomy position transfer bed 1 is mainly suitable for patients with relatively healthy physical conditions. However, for patients with hunchbacks, using Figure 1 The lithotomy position transfer bed 1 shown has many problems. Due to changes in the physiological structure of the spine, it is difficult for hunchback patients to lie flat on the transfer bed like normal people and maintain a stable lithotomy position during transfer. In actual operation, when facing a hunchback patient who needs to use a lithotomy position transfer bed, medical staff often stuff a large amount of padding under the patient's body, trying to make the hunchback patient lie as flat as possible on the transfer bed. However, this operation method not only greatly increases the workload of medical staff, but also during the transfer process, due to factors such as the sliding and displacement of the padding, it is impossible to ensure that the hunchback patient can maintain a stable lithotomy position, which may cause physical discomfort to the patient and even affect the subsequent treatment process. Summary of the invention

[0004] The present invention is intended to provide a lithotomy position device to solve the problem that the existing lithotomy position transfer bed is not suitable for transferring kyphotic patients in the lithotomy position.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme:

[0006] A lithotomy position device comprises a transfer bed, which comprises a bed frame, and wheels are installed at the bottom of the bed frame, and is characterized in that a transfer bed board is detachably fixed to the bed frame by bolts, a leg frame is fixed to the tail of the transfer bed board, and a strap is arranged on the leg frame, a through hole is opened on the transfer bed board, and a cover plate for closing the through hole is hingedly connected on both sides of the through hole toward the tail and the head of the bed, and after the two cover plates are covered on the through holes, the surface of the cover plate is flush with the surface of the transfer bed board, a flexible padding layer is fixed to the bottom surface of the cover plate, an elastic net is sealed at the through hole, and the elastic net is located below the cover plate, and pads are slidably connected to the bottom of the head and tail ends of the transfer bed board, and the pads are used to pad under the transfer bed board to form a deformation space between the transfer bed board and the bed frame for the elastic net to deform.

[0007] The principles and beneficial effects of this program are:

[0008] 1. This solution can be used by both healthy patients and hunchback patients. When used by healthy patients, the two cover plates cover the through holes and are flush with the surface of the transfer bed board. Healthy patients can lie flat on the transfer bed board normally, with their legs spread apart and fixed on two leg frames by straps to form a lithotomy position. When facing hunchback patients, this solution shows a unique adaptive design. First, by loosening the bolts, the pad is placed at the bottom of the head and tail ends of the transfer bed board to construct a deformation space between the transfer bed board and the bed frame. Then, the two cover plates covering the through holes are turned over toward the head and foot of the bed respectively to expose the through holes. When the hunchback patient lies flat on the transfer bed board, the hunchback part of the patient can be placed in the through hole, supported by the elastic net below. The elastic net has good elasticity and deformation ability, and can be adaptively adjusted according to the degree of hunchback of different hunchback patients, so that the body of the hunchback patient can lie as flat as possible on the transfer bed. In addition, after the cover is flipped open, the flexible padding layer on its bottom will be placed under the two edges of the hunchback part of the hunchback patient, further optimizing the support and comfort of the patient's back.

[0009] 2. This solution is suitable for both healthy patients and hunchback patients, avoiding the limitation that traditional lithotomy transfer beds can only serve healthy patients, expanding the scope of use of the equipment, and having wider applicability in clinical applications.

[0010] 3. Compared with the traditional method, medical staff no longer need to stuff a lot of padding under the hunchbacked patients. Only simple operations such as loosening the bolts, placing pads, and opening the cover can complete the adjustment of the transfer bed to accommodate hunchbacked patients, which greatly reduces the operating steps and labor intensity of medical staff.

[0011] 4. The traditional method of using a large amount of padding can easily cause the patient's position to change due to the padding sliding and shifting during transportation. However, this solution uses the elastic net to stably support the hunchback part of the hunchback patient, and the flexible padding layer to assist in maintaining the comfort and stability of the patient's back. It can effectively ensure that the hunchback patient can maintain a stable lithotomy position during transportation, reduce the risk of physical discomfort caused by changes in body position, and ensure that the subsequent treatment process is not affected.

[0012] 5. When a hunchback patient uses it, he only needs to loosen the bolts and slide the pad under the transfer bed board to raise the transfer bed board, so that the hunchback part of the hunchback patient can be placed in the raised space after lying down. This arrangement of the present scheme only requires improvement of the transfer bed board of the existing lithotomy transfer bed, and there is no need to change other parts of the lithotomy transfer bed, for example, there is no need to open a through hole on the bed frame of the existing transfer bed, and there is no need to shift and improve the base under the bed frame, which greatly saves the improvement cost. The method of raising the transfer bed board in the present scheme can be suitable for the use of most hunchback patients through the raised space. In addition, the pad is slidably stored under the transfer bed board, and can be directly slid to the bottom of the transfer bed board when needed, which is easy to operate, and there is no need to worry about the loss and storage of the pad.

[0013] Preferably, as an improvement, a circle of steps for supporting the cover plate is provided on the inner wall of the through hole, and the edge of the elastic net is fixed on the steps.

[0014] Beneficial effect: Setting the steps can better support the cover when it is closed. When a healthy patient uses the transfer bed, the cover tightly covers the through holes, providing a flat lying surface for the patient. At this time, the steps provide a firm support for the cover, helping to maintain the overall flatness of the transfer bed.

[0015] Preferably, as an improvement, tension sensors are connected to the four sides of the elastic net, the tension sensors are arranged in the steps, the tension sensors are electrically connected to the controller, the controller is electrically connected to the alarm and four indicator lights, the four indicator lights are respectively installed on the four sides of the transfer bed board and correspond to the tension sensors on the four sides of the elastic net.

[0016] Beneficial effects:

[0017] 1. During the patient transfer process, especially for hunchback patients who maintain the lithotomy position, the body may move up and down or left and right due to various reasons. Once the patient's body moves, the tension sensor in the corresponding direction will be triggered due to the change in force. The sensor quickly transmits the signal to the controller connected to it, and the controller immediately activates the alarm mechanism. The alarm sounds and the indicator light in the corresponding direction lights up. This allows medical staff to detect abnormal changes in the patient's body position at the first time.

[0018] 2. By observing the indicator lights, medical staff can intuitively and quickly know the specific direction in which the patient's body has shifted. For example, if the indicator light on the left side of the transfer bed is on, the medical staff can clearly see that the patient's body has shifted to the left. This clear indication greatly saves the time for medical staff to judge the direction of the patient's body displacement, so that they can adjust the patient's position in a timely and accurate manner, ensuring that the patient is always in a safe, comfortable and treatment-compliant lithotomy position.

[0019] Preferably, as an improvement, the edge of the through hole, the edge of the step and the edge of the cover plate are all rounded.

[0020] Beneficial effects: After the rounded corners are processed, the risk of scratches caused by sharp corners is eliminated, and the safety and comfort of patients during transportation are improved.

[0021] Preferably, as an improvement, the padding layer is an air bag filled with gas.

[0022] Beneficial effect: Using airbags as the cushioning layer is not only waterproof and easy to clean, but also the inflation volume of the airbags can be adjusted as needed, thereby adjusting the height of the cushioning layer.

[0023] Preferably, as an improvement, the airbag is connected to an air pump for continuously inflating and deflating the airbag.

[0024] Beneficial effects: Based on the use of airbags as cushioning layers, the air pump's continuous inflation and deflation function can massage the patient's back. When patients are transported or treated in the lithotomy position for a long time, their back muscles are prone to soreness and fatigue due to maintaining the same posture for a long time. The air pump regularly and repeatedly inflates and deflates the airbags, allowing the airbags to continuously squeeze the patient's back. This massage effect helps promote blood circulation in the patient's back, relieve muscle tension, and effectively reduce the patient's discomfort during transportation.

[0025] Preferably, as an improvement, an air pipe hole is opened in the cover plate, the air pipe hole passes through the cover plate in the thickness direction, a bellows is arranged in the air pipe hole, one end of the bellows is connected with the airbag, and the other end of the bellows is connected with a hard counterweight pipe head, the counterweight pipe head is slidably connected in the air pipe hole, an air connecting pipe is installed in the transfer bed board, one end of the air connecting pipe extends to the outside of the transfer bed board and is installed with a pipe joint, the pipe joint is used to connect with the air pump, the other end of the air connecting pipe is flared and passes through the surface of the transfer bed board and is flush with the surface of the transfer bed board, the diameter of the air connecting pipe is larger than the diameter of the counterweight pipe head, and when the cover plate closes the through hole, the counterweight pipe head is received in the air pipe hole, and after the cover plate is flipped up, the free end of the counterweight pipe head can slide to the outside of the air pipe hole under the action of gravity and extend into the air connecting pipe.

[0026] Beneficial effects:

[0027] 1. After the cover is flipped over to the transfer bed board, the tracheal hole is aligned with the pipe joint, the counterweight pipe head slides down under the action of gravity and slides out of the tracheal hole, the corrugated tube is stretched, and the counterweight pipe head can slide deep into the tracheal tube after sliding out, thereby realizing the automatic connection between the counterweight pipe head and the tracheal tube. Medical staff do not need to manually connect the complex tracheal lines, which greatly saves operation time. In the medical transfer scenario, time is life. This convenient automatic connection method allows medical staff to complete the adjustment of the equipment more quickly, improving overall work efficiency.

[0028] 2. The weighted pipe head slides down naturally under the action of gravity, and after sliding out of the air pipe hole, it can accurately penetrate into the air pipe. The design of the bellows can not only ensure the connectivity of the air pipe during the sliding process of the weighted pipe head, but also adapt to different cover opening angles and position changes.

[0029] 3. The connection structure cleverly solves the tracheal connection problem of the device in different states (the cover is closed when used by healthy patients, and the cover is opened when used by hunchback patients). When used by healthy patients, the counterweight pipe head is stored in the tracheal hole, which does not affect the flatness and normal use of the transfer bed board. When facing a hunchback patient who needs to open the cover, the connection structure can automatically adapt to achieve the connection between the air pump and the airbag, so that the device can meet the needs of different patients without the need for additional complex tracheal switching or connection devices, enhancing the versatility and practicality of the equipment.

[0030] Preferably, as an improvement, a circle of anti-leakage membrane is provided on the inner wall of the air connecting pipe, the outer edge of the anti-leakage membrane is fixed on the inner wall of the air connecting pipe, the inner diameter of the anti-leakage membrane is smaller than the inner diameter of the counterweight tube head, and the anti-leakage membrane is located below the counterweight tube head when the counterweight tube head is extended into the air connecting pipe.

[0031] Beneficial effects: When the airbag is inflated, the gas flows into the weighted tube head from bottom to top, and the driving force of the gas flow causes the anti-leakage membrane to tilt upward, thereby tightly covering the tiny gap between the weighted tube head and the inner wall of the air tube. This process ensures that the gas will not leak during transmission, greatly improving the airtightness of the connection. Good airtightness ensures that the airbag can be inflated and deflated according to the predetermined pressure and rhythm, providing patients with a continuous, stable and comfortable massage experience, and avoiding poor massage effects caused by insufficient or unstable air pressure. This solution cleverly uses the characteristics of gas flow to achieve an automatic sealing function without the need for additional sealing devices or complicated operations.

[0042] The following is further described in detail through specific implementation methods:

[0043] The figure marks in the drawings of the specification include: transfer bed 1, bed frame 2, wheels 21, leg frame 22, transfer bed board 3, bolts 31, pad 32, cover plate 4, hinge 41, notch 42, through hole 43, step 44, elastic net 45, cushioning layer 46, indicator light 47, air pipe hole 5, counterweight pipe head 51, bellows 52, air connecting pipe 6, pipe joint 61, anti-leakage membrane 7.

[0044] Embodiment 1:

[0045] like Figure 2 and Figure 3 As shown, a lithotomy position device comprises a transfer bed 1. The structure of the transfer bed 1 is as follows: Figure 1The present invention is improved on the basis of the existing lithotomy position transfer bed 1 shown in the figure, mainly improving the transfer bed plate 3, and the other structures are not changed. Specifically, the transfer bed 1 includes a bed frame 2, and a wheel 21 is installed at the bottom of the bed frame 2, and the wheel 21 adopts a universal wheel with a brake. The improved transfer bed plate 3 is detachably fixed to the bed frame 2 by bolts 31, and the rear bolts of the transfer bed plate 3 are fixed with a leg frame 22, and the leg frame 22 is provided with a strap (not shown in the figure). The following mainly introduces the improved part in detail.

[0046] A through hole 43 is provided on the transfer bed board 3, and cover plates 4 for closing the through hole 43 are hingedly connected on both sides of the through hole 43 toward the foot and the head of the bed through hinges 41. A notch 42 is provided on one of the cover plates 4 as a force point to facilitate opening the two cover plates 4, and the hinge 41 is installed on the surface of the transfer bed board 3. The surface of the transfer bed board 3 and the surfaces of the two cover plates 4 are both provided with installation grooves just for installing the hinge 41, so as to ensure that after the two cover plates 4 are covered on the through hole 43, the surface of the cover plate 4 is flush with the surface of the transfer bed board 3, and the hinge 41 does not protrude from the surface of the transfer bed board 3, so as to avoid discomfort to the patient as much as possible.

[0047] A flexible padding layer 46 is glued and fixed to the bottom surface of the cover plate 4. In this embodiment, the padding layer 46 is made of sponge, rubber, etc. An elastic net 45 is sealed at the through hole 43. The elastic net 45 is located below the cover plate 4. A circle of steps 44 for supporting the cover plate 4 is integrally formed on the inner wall of the through hole 43. The edge of the elastic net 45 is fixed to the step 44 by screws or glue. The bottom sliding connection of the head and tail ends of the transfer bed plate 3 (implemented by dovetail grooves and dovetail sliders) is provided with a pad 32. The pad 32 is used to pad under the transfer bed plate 3 to form a deformation space between the transfer bed plate 3 and the bed frame 2 for the elastic net 45 to deform. The height of the pad 32 is set according to actual needs and is only schematically shown in the figure. The edges of the through hole 43, the edges of the steps 44 and the edges of the cover plate 4 are all rounded to avoid scratches caused by sharp corners.

[0048] A method of using the lithotomy position device is as follows:

[0049] When a healthy patient (a patient without hunchback, as opposed to a hunchback patient) uses the bed, the two cover plates 4 close the through holes 43, and the transfer bed plate 3 forms a flat bed surface, that is, Figure 2 In the state shown, a healthy patient can lie flat on the transfer bed plate 3, with legs spread apart and placed on the leg frame 22 and fixed by straps, thereby maintaining the lithotomy position for transfer. When the patient needs to be transferred to an operating bed or a treatment bed, the bolts 31 are loosened, and the transfer bed plate 3 and the patient are lifted onto the operating bed or the treatment bed.

[0050] When a hunchback patient uses it, first loosen the screws, slide the two pads 32 under the two ends of the transfer bed plate 3, and raise the transfer bed plate 3 so that there is enough space under the through hole 43, that is, Figure 3 The state shown. Then the two cover plates 4 are opened from the head and foot of the bed respectively to expose the through hole 43. After the hunchback patient lies flat on the transfer bed board 3, the hunchback part of the patient can be placed in the through hole 43 and supported by the elastic net 45 below. The elastic net 45 has good elasticity and deformation ability, and can be adaptively adjusted according to the degree of hunchback of different hunchback patients. In addition, the two edge parts of the hunchback part are supported by the padding layer 46 on the two opened cover plates 4, so that the hunchback patient can lie as flat as possible on the transfer bed board 3. In actual use, the cover plate 4 can be made of a material with better strength, so that the thickness of the cover plate 4 can be reduced as much as possible. In addition, the setting of the padding layer 46 on the cover plate 4 can further improve the comfort of the patient.

[0051] Embodiment 2:

[0052] Combination Figure 4 As shown, the difference between this embodiment and embodiment 1 is that tension sensors (not shown in the figure) are connected to the four sides of the elastic net 45. The tension sensors are micro tension sensors in the prior art. The tension sensors are installed in the step 44. The tension sensors are electrically connected to a controller (not shown in the figure). The controller is electrically connected to an alarm (not shown in the figure) and four indicator lights 47. The four indicator lights 47 are respectively installed on the four sides of the transfer bed board 3 and correspond to the tension sensors on the four sides of the elastic net. The alarm uses a buzzer alarm.

[0053] In this embodiment, when the body of a hunchback patient moves toward any direction of the through hole 43, such as up, down, left, or right, during transportation, the tension sensor in that direction will sense the change in tension of the elastic net 45 and transmit the change to the controller. The controller then controls the alarm to sound and at the same time controls the indicator light 47 installed on the corresponding edge to light up, so as to prompt the medical staff to which side the patient's body has moved so that the medical staff can respond in time.

[0054] Embodiment 3:

[0055] The difference between this embodiment and embodiment 1 is that the padding layer 46 is an air bag filled with gas. Using the air bag as the padding layer 46 can not only achieve a soft supporting effect, but also be waterproof and anti-fouling, and easy to clean.

[0056] Embodiment 4:

[0057] The difference between this embodiment and embodiment 3 is that the airbag is connected to an air pump (not shown in the figure) for continuously inflating and deflation of the airbag, and the air pump adopts an intelligent air pump, a programmable air pump, etc. in the prior art. The air pump continuously inflates and deflates the airbag repeatedly, which can repeatedly squeeze the back of the hunchback patient, achieve back massage, and further reduce the occurrence of pressure sores.

[0058] Embodiment 5:

[0059] Combination Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the difference between this embodiment and embodiment 4 is that an air pipe hole 5 is opened in the cover plate 4, and the air pipe hole 5 penetrates the cover plate 4 from the thickness direction. A bellows 52 is installed in the air pipe hole 5, and one end of the bellows 52 is connected to the air bag, and the other end of the bellows 52 is connected to a hard counterweight pipe head 51. The counterweight pipe head 51 is slidably connected in the air pipe hole 5 by sliding a slider in a slide groove on the inner wall of the air pipe hole 5. The end of the slide groove is located at the orifice of the air pipe hole 5 and does not penetrate the inner wall of the air pipe hole 5, thereby limiting the counterweight pipe head 51 from slipping out of the air pipe hole 5. An air connection pipe 6 is built into the transport bed board 3, and one end of the air connection pipe 6 extends to the outside of the transport bed board 3 and is installed with a pipe joint 61, which is used to communicate with the air pump. The other end of the air connection pipe 6 is flared and penetrates the surface of the transport bed board 3 and is flush with the surface of the transport bed board 3. The diameter of the air pipe 6 is slightly larger than that of the counterweight pipe head 51, and the difference between the two diameters is about 2-3mm, so as to achieve better air tightness. When the cover plate 4 closes the through hole 43, the counterweight pipe head 51 is received in the air pipe hole 5, that is, Figure 6 In the state shown, after the cover plate 4 is opened, the free end of the weight pipe head 51 can slide to the outside of the air pipe hole 5 under the action of gravity and extend into the air pipe 6, that is, Figure 8 In actual use, by controlling the position accuracy of the air pipe hole 5 and the end of the air connection pipe 6, the air pipe hole 5 can be accurately aligned with the air connection pipe 6 after the cover plate 4 is opened, so that the counterweight pipe head 51 can be smoothly inserted into the air connection pipe 6.

[0060] With this embodiment, when the cover plate 4 is opened, the tracheal hole 5 is aligned with the air connection pipe 6, and the weighted pipe head 51 in the tracheal hole 5 slides down under the action of gravity and extends into the air connection pipe 6. At this time, the bellows 52 stretches, thereby realizing the automatic connection between the weighted pipe head 51 and the air connection pipe 6. At this time, the air pump can be turned on to inflate and deflate the airbag, and the patient's back is squeezed by the inflation and deflation of the airbag to massage the patient, without the need for additional manual connection of the inflation pipe. When the cover plate 4 is reset to cover the through hole 43, the weighted pipe head 51 slides back into the tracheal hole 5 under the action of gravity.

[0061] Embodiment 6:

[0062] Combination Fig. 9 and Fig.10As shown, the difference between this embodiment and embodiment 5 is that a circle of anti-leakage membrane 7 is glued on the inner wall of the air connecting pipe 6, and the anti-leakage membrane 7 is made of rubber membrane or silicone membrane. The outer edge of the anti-leakage membrane 7 is glued and fixed to the inner wall of the air connecting pipe 6. The inner diameter of the anti-leakage membrane 7 is smaller than the inner diameter of the counterweight pipe head 51. When the counterweight pipe head 51 is extended into the air connecting pipe 6, the anti-leakage membrane 7 is located below the counterweight pipe head 51.

[0063] When the air pump inflates the airbag, the air flows upward from the air connecting pipe 6. At this time, the anti-leakage membrane 7 tilts upward under the action of the air flow, and the inner edge of the anti-leakage membrane 7 is blown up and sticks to the inner edge of the counterweight tube head 51, thereby sealing the gap between the counterweight tube head 51 and the inner wall of the air connecting pipe 6, thereby improving the sealing of the connection between the two.

[0064] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
