Description

Technical Field

[0001] The embodiments of the present application belong to the field of medical devices, and in particular, relate to a fixing device for medical equipment. Background Art

[0002] Since life support equipment has many components, it has a separate frame loading device in the ward, which requires a separate and larger volume space as described in US20190365979A. However, outside the ward, such as in automobile and aviation operations, the operating devices in transportation movements bring new challenges to loading methods. At present, there are many existing solutions to solve the problem of unifying single medical devices (such as pump drivers or oxygenators) of life support equipment in a holder. In actual operation, there are still many problems with the transportation device of the portable holder that accompanies the patient's transportation.

[0003] For example, CN116322883A provides a solution for fixing the pump driver and oxygenator on the side of the holder. It adopts a long box design, which is relatively large and heavy. It is not suitable for hanging on the side of the bed, and often requires another separate frame to be transported with the bed frame, which requires a high space for the transport tool. For example, US20130105425A designs a separate basket for the host, which needs to be placed separately, and the basket also lacks a means of fixing. For example, EP4037598B and DE202019002888U1 are designed with the concept of specific fixation of portable systems on beds. The customization cost and verification fee are high, and the cost of additional fixing parts is more than 100,000 yuan.

[0004] There is also a design that is hung on the side railing of the bed. Since the ECMO loading device is relatively heavy as a whole during operation, the impact of rollover needs to be considered.

[0005] There is also a method of installing a storage rack above the bed or hanging it at a higher position in the cabin. However, the machine is higher than the patient, which can easily cause the risk of negative pressure during the operation of the equipment. This is not recommended for circulatory life support equipment.

[0006] In addition, the medical conditions in different places are different, and there are many types of transport beds, which leads to different fixing conditions when the portable transport system is actually used, resulting in some customized fixing devices being unable to match its structure. In reality, the machine is often not fixed during operation on the ambulance. When the life support equipment encounters emergency braking and bumps during operation, the equipment lacks fixing means, which poses a greater safety risk to the patient. Summary of the invention

[0007] In order to solve the problem of fixing the ECMO system during transportation, the present application provides a fixing device for medical equipment, which is used to fix the medical equipment. The fixing device for medical equipment includes:

As a further improvement of the embodiment of the present invention, the locking portion is arc-shaped, the unlocking portion is linear, and the two ends of the unlocking portion are respectively connected to the two ends of the locking portion.

[0012] As a further improvement of the embodiment of the present application, the locking member includes a first fixing groove, and the main body is provided with a latch member, which is used to penetrate the first fixing groove and the main body to prevent the main body and the locking member from rotating relative to each other.

[0013] As a further improvement of the embodiment of the present invention, the latch member is an elastic ball.

[0014] As a further improvement of the embodiment of the present invention, the locking portion is provided with a second fixing groove, and the second fixing groove is used to fix the rope.

[0015] As a further improvement to the embodiment of the present invention, there are at least two locking members, and at least two of the locking members are arranged non-parallel.

[0016] As a further improvement to an embodiment of the present invention, the second plate is a hollow plate, the locking piece is arranged in the second plate, and a through hole is provided on the second plate to facilitate the locking piece to be exposed on the second plate.

[0027] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0028] For the fixing device of medical equipment in this application, please refer to Figure 1-Figure 5 , comprises a main body 10 and a locking member 20.

[0029] The main body 10 includes a first mounting plate 110 and a second mounting plate 120, the second mounting plate 120 is connected to the edge of the first mounting plate 110, and the medical device is fixed to the first mounting plate 110 and / or the second mounting plate 120;

[0030] The locking member 20 includes a locking portion 210 and an unlocking portion 220. The locking member 20 is rotatably connected to the second mounting plate 120. The locking member 20 is rotated to change the positions of the locking portion 210 and the unlocking portion 220. When the locking portion 210 is downward, the locking portion 210 extends downward from the second mounting plate 120 and the locking portion 210 is locked with the medical device 30. When the unlocking portion 220 is downward, the unlocking portion 220 is unlocked from the medical device 30 and the locking portion 210 extends upward from the second mounting plate 120. The locking portion 210 is provided with a second fixing groove 2110, and the second fixing groove 2110 is used to fix the rope.

[0031] Compared with the prior art, in the fixing device of medical equipment in the present application (hereinafter referred to as the portable rack), the medical equipment is fixed on the first mounting plate 110 or the second mounting plate 120, or is installed on the first mounting plate 110 and the second mounting plate 120 at the same time. Among them, the locking member 20 structure can provide two states of fixing methods. 1. When the patient is transported by air or car, the main body 10 can be placed on the bed, with the locking member 20 on it facing upward, and the second fixing groove 2110 can provide multiple fixing positions for the rope belt, which is convenient for the portable rack to be fixed on the bed. 2. When the main body 10 is put back on the shifting vehicle after the transfer, the main body 10 is placed on the fixed position of the shifting vehicle, and the multiple locking parts 210 can be rotated downward, and the locking parts 210 are quickly fixed on the shifting vehicle. The locking parts 210 can be rotated upward, and the locking parts 210 are unlocked from the shifting vehicle. It not only solves the lack of fixing means of the existing actual hospital transport equipment and reduces safety hazards, but also solves the problem of rapid fixing and disassembly between shifting vehicles.

[0032] The above-mentioned shifting vehicle belongs to one embodiment of the vehicle frame fixing device 30 .

[0033] The fixing device of the medical device in the present application is applied to the field of ECMO (extracorporeal membrane oxygenation) but is not limited to the field of ECMO (extracorporeal membrane oxygenation). ECMO is an important technology for maintaining the cardiopulmonary function of patients. ECMO extracts blood from the body's circulation, oxygenates it, and then transports it back to the body to replace damaged lung or heart function.

[0034] The ECMO system includes an oxygenator, a pump and a main unit, all of which need to be tied to the patient at all times, and the relative height to the patient must remain unchanged to maintain the patient's vital signs. The fixing device of the medical device in the present invention can be placed between the patient's legs when in use, and is fixed to the patient's stretcher or mobile cart together with the patient. The stretcher or cart is used for the patient to lie flat. It is necessary to keep the patient's vital signs from disappearing completely. At this time, the fixing device of the medical device in the present invention is generally located between the patient's legs and fixed to the stretcher or mobile cart. The stretcher or cart is used for the patient to lie flat.

[0035] The main body 10 generally has a semi-enclosed receiving cavity for fixing and installing the oxygenator, the pump and the host. At the same time, a handle 140 is generally provided on the main body 10 to facilitate medical personnel to lift the fixing device of the entire medical device.

[0036] Generally, the main body 10 further includes a third mounting plate 130 , which is fixed to the edge of the first mounting plate 110 , and the medical device is fixed in an installation space enclosed by the first mounting plate 110 , the second mounting plate 120 and the third mounting plate 130 .

[0037] The first mounting plate 110 is usually provided with buttons, a display screen, etc., for explaining the use method or status of the fixing device of the medical device in the present invention.

[0038] In a more preferred embodiment, the locking member 20 further includes a toggle portion 230 , which is disposed on an edge of the locking portion 210 .

[0039] In this embodiment, the toggle part 230 can facilitate the medical staff to better toggle the locking member 20. The toggle member is in various forms, for example, some anti-slip lines can be provided on the edge of the locking part 210, thereby increasing the convenience of the medical staff to toggle the locking member 20.

[0040] Alternatively, some paddles may be provided at the edge of the locking portion 210 , the paddles being fixedly connected to the locking portion 210 , and medical personnel may paddle the paddles to achieve the purpose of rotating the locking member 20 .

[0041] It should be noted that the toggle portion 230 can actually be arranged on the unlocking portion 220, or can be arranged independently of the unlocking portion 220 and the locking portion 210. In this embodiment, considering that the locking portion 210 is the main force-bearing portion, the toggle portion 230 is arranged on the edge of the locking portion 210, which is conducive to the medical staff to spend less effort to realize the rotation of the locking member 20. Please refer to Figure 3 and Figure 4 , Figure 3 and Figure 4 The fixing of the fixing device of the medical equipment on the ECMO frame is described. Since the frame of the main body 10 is a portable device, when returning to the frame in the hospital, the fixing device of the medical equipment, such a portable device, needs to be combined and fixed with another device such as a frame loading device. The frame fixing device 30 is generally compatible with the fixing device of the medical equipment. Generally speaking, the frame fixing device 30 has at least one mounting seam 310, and one or both ends of the mounting seam 310 have a mounting opening 320. For example, the structure of the frame fixing device 30 can be provided on the shifting vehicle of the CN 308320878 S patent. When the locking member 20 is in the downward rotation state, after entering the mounting seam 310, the fixing of the fixing device of the medical equipment in the lateral direction is completed.

[0042] The toggle part 230 can also play a fixing role. For example, a clamping part corresponding to the toggle part 230 is provided on the main body 10 or the medical device 30, so that the toggle part 230 can be clamped on the toggle part 230 after being rotated into place.

[0043] In a more preferred embodiment, the locking portion 210 is arc-shaped, and the toggle portion 230 has more than one function. The toggle portion 230 can be integrally cast in the arc-shaped structure, and can be used as a toggle when it is upward, and can be used as a locking piece when it is downward. Figure 4The middle serves as an upward latch so that the fixing frame cannot be lifted out after being placed in the fixing position of the trolley.

[0044] In this embodiment, the locking portion 210 and the unlocking portion 220 are connected end to end, and the locking portion 210 is arc-shaped, and preferably, the locking portion 210 is semicircular. The locking portion 210 is arc-shaped, so when the locking member 20 is rotated, the locking portion 210 is protruded relative to the unlocking portion 220, so that the locking portion 210 can be locked with the frame fixing device 30, while the unlocking portion 220 cannot be locked with the frame fixing device 30.

[0045] The arc-shaped setting of the locking portion 210 makes the locking portion 210 and the frame fixing device 30 lock more smoothly. Of course, the locking portion 210 can also be set in a non-arc shape. For example, the locking portion 210 is triangular, trapezoidal or other irregular shapes.

[0046] The toggle part 230 has more than one function. The toggle part 230 can be integrally cast in the arc-shaped locking part 210, and can be used as a toggle when it is upward, and can be used as a locking piece when it is downward. Figure 4 The middle serves as an upward latch so that the fixing frame cannot be lifted out after being placed in the fixing position of the trolley.

[0047] In a more preferred embodiment, the locking member 20 includes a first fixing groove 2210 , and a latch member 150 is provided on the main body 10 . The latch member 150 is used to penetrate the first fixing groove 2210 and the main body 10 to prevent the main body 10 and the locking member 20 from rotating relative to each other.

[0048] In this embodiment, when the locking member 20 is not needed, in order to prevent the locking member 20 from swinging relative to the main body 10 or the locking member 20 partially protruding from the main body 10 (which is not conducive to the placement of the main body 10), the locking member 20 needs to be fixed.

[0049] At this time, the latch member 150 is inserted into the first fixing groove 2210 and the main body 10, so that the locking member 20 and the main body 10 are relatively fixed and cannot rotate. When the locking member 20 is needed, the latch member 150 is removed and the locking member 20 can be used normally.

[0050] In a more preferred embodiment, the latch member 150 is an elastic ball.

[0051] Elastic wave ball usually refers to a mechanical part, also known as positioning bead, ball plunger or spring plunger. It is composed of a shell, a spring and a ball or a cylinder, and is a load device. Elastic wave ball is widely used in medical equipment, lubrication equipment, pneumatic tools and other products. Engineers often use it in molds, fixtures, assembly and other work. The movement of the ball is pushed by a spring with a certain pressure, so that the equipment can run smoothly.

[0052] Alternatively, the elastic bead is always in contact with the groove 2210, and only provides a slight fixing effect. When a slight force is applied to the unlocking portion 220, the elastic bead is separated from the groove 2210 of the buckle.

[0053] Normally, pressing the elastic bead once can fix the locking member 20 and the main body 10 , and pressing the elastic bead again can release the locking member 20 and the main body 10 .

[0054] In a more preferred embodiment, the number of the locking members 20 is at least two, and at least two of the locking members 20 are arranged non-parallel.

[0055] The locking member 20 is mainly used to limit the movement of the fixing device of the medical device in the present invention in a horizontal direction. Therefore, there are at least two locking members 20 and the two locking members 20 are arranged non-parallel, and the frame fixing device 30 is used to limit the fixing device of the medical device in the vertical direction, so as to finally achieve a full-scale fixing work of the fixing device of the medical device.

[0056] Generally, there are three locking members 20. Two locking members 20 are arranged on the sides of the main body 10, preferably symmetrically. Another locking member 20 is arranged on the front of the main body 10, and this locking member 20 is usually arranged perpendicular to the other two locking members 20.

[0057] In a more preferred embodiment, please refer to Figure 5 The second plate 120 is a hollow plate, the locking piece 20 is disposed in the second plate 120 , and a through hole is provided on the second plate 120 so that the locking piece 20 is exposed on the second plate 120 .

[0058] In order to ensure the aesthetics of the fixing device of the medical equipment in the present invention, the locking member 20 is arranged in the second plate 120, and the locking part 210 is rotated out and in through a through hole (not shown) preset in the second plate 120.

[0059] In a more preferred embodiment, at least two locking members 20 are symmetrically arranged relative to the second plate 120 and the two locking members 20 are coaxially connected.

[0060] In this embodiment, when any one of the locking members 20 is rotated, the other locking member 20 is rotated synchronously, so that the upper and lower locking members 30 are simultaneously unlocked or locked with the frame fixing device 30 .

[0061] When the unlocking portion 220 is upward and downward, the unlocking portion 220 does not protrude from the second plate 120 .

[0062] When the unlocking portion 220 is located away from the third plate 130 of the main body, the unlocking portion 220 is not higher than the bottom surface of the main body 10 .

[0063] When the unlocking portion 220 is in a state of being away from the third plate 130 , the locking portion is not higher than the bottom surface of the main body 10 , so the fixing device of the medical equipment can be laid flat.

[0064] The following combination Figure 3 and Figure 4 The specific usage of the fixing device of the medical device in this application is comprehensively introduced:

[0065] 1. The ECMO system is fixedly installed on the main body 10;

[0066] 2. With the locking piece 20 facing upward, a rope is passed through the second fixing groove 2110 of the locking piece 20 to secure the ECMO medical device during transfer between cars and airplanes.

[0067] 3. Transfer the patient together with the fixture of the medical device to the frame fixture 30;

[0068] 4. Move the two locking members 20 in the lateral direction so that the locking portion 210 faces the frame fixing device 30. The mounting seam 310 of the frame fixing device 30 limits the movement of the fixing device of the medical device in the lateral direction.

[0069] 5. Move the locking member 20 in the front direction so that the locking portion 210 faces the frame fixing device 30. The mounting seam 310 of the frame fixing device 30 limits the movement of the fixing device of the medical device 30 in the front-rear direction.

[0070] 6. After the transfer is completed, the locking member 20 is moved so that the unlocking portion 220 faces the frame fixing device 30, thereby unlocking and separating the locking member 20 and the medical device 30.

[0071] 7. Press the latch member 150 preset on the main body 10 to make the latch member 150 pass through the first fixing groove 2210 . At this time, the locking member 20 is fixed relative to the main body 10 .

[0072] 8. Repeat steps 6 and 7 to fix all the locking members 20 relative to the main body 10.

[0073] It should be noted that, in the above steps, the latch member 150 can also fix the locking member 20 relative to the main body 10 when the locking member 20 and the medical device 30 are fixed.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
