Description

Technical Field

[0001] This utility model relates to a support device, and more particularly to a leg support device. Background Technology

[0002] Currently, when hospital nurses care for patients with leg injuries, they need to elevate the injured leg. The main purpose of elevating the injured limb is to reduce swelling, relieve pain, and promote tissue repair. By using gravity to reduce the accumulation of blood and body fluid in the injured area, vascular pressure can be reduced, circulation can be improved, thereby accelerating recovery and reducing the risk of complications. Elevating the injured limb requires the use of a leg support device.

[0003] A clinical nursing leg support device, as disclosed in Chinese Patent Publication No. CN222584881U, includes: a mounting frame; a fixed column is provided on the upper part of the mounting frame and is fixedly connected to the mounting frame; a telescopic column is provided inside the fixed column and is telescopically connected to the fixed column; a support rod is provided on the side of the telescopic column and is threadedly connected to the telescopic column; an adjusting block is provided on the surface of the support rod and a hanging rope is provided at the lower part of the adjusting block. In use, the mounting frame is snapped onto the edge of the bed frame. By rotating the adjusting rod, the top plate contacts the bed frame, thus fixing the mounting frame to the bed frame. The height between the telescopic column and the fixed column is adjusted to adjust the support rod to a suitable height. The position of the adjusting block is moved so that the hanging plate corresponds to the patient's leg, achieving leg support. This device has a simple structure, is easy to operate, small in size, easy to move, and suitable for different occasions. The aforementioned existing clinical nursing leg support device has some problems. First, the device's hanging plate is in direct contact with the patient's leg, and it is inevitable that it will get dirty with medicine stains and other contaminants during use. However, it is difficult to disassemble and clean the hanging plate. Second, when the patient's leg is placed on the hanging plate, which is far away from the vertical support components, the horizontal support rod will act as a lever, causing the vertical support components to be subjected to a large tilting force. As the force exerted by the patient's leg on the hanging plate increases, there is a risk of bending of the vertical support components such as the telescopic column. Utility Model Content

[0004] The purpose of this invention is to provide a leg support device to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leg support device, comprising a telescopic support rod, a mounting bracket fixedly connected to the lower end of the telescopic support rod, a horizontal support rod fixedly connected to the upper end of the telescopic support rod, an adjusting block slidably mounted on the horizontal support rod, a suspension rope fixedly connected below the adjusting block, an arc-shaped support plate fixedly connected to the other end of the suspension rope, limiting protrusions symmetrically fixedly connected to the upper edge of the arc-shaped support plate, a supporting cotton cloth provided inside the arc-shaped support plate, connecting collars embedded and installed near the two side edges of the supporting cotton cloth, the connecting collars sleeved on the limiting protrusions, U-shaped locking blocks installed on both sides of the arc-shaped support plate, and a counterweight box fixedly connected to one end of the horizontal support rod.

[0006] Preferably, a sealed door is rotatably installed on one side of the counterweight box, and several counterweight blocks are placed inside the counterweight box.

[0007] Preferably, the arc-shaped support plate is symmetrically fixed with connecting lugs on its front and rear sides, and the connecting lugs are fixed to the lifting ropes.

[0008] Preferably, the U-shaped card block has several limiting holes, which cooperate with the limiting protrusions.

[0009] Preferably, a return spring is fixedly connected to the bottom of the U-shaped card block, and a compression plate is fixedly connected to the other end of the return spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Push the U-shaped locking block upwards to disengage the limiting insertion hole from the limiting protrusion. At this point, the U-shaped locking block can move to the side and separate from the arc-shaped support plate, releasing the restriction on the connecting collar. The support cotton cloth can then be removed separately for cleaning and disinfection, avoiding the problem of dirt on the support cotton cloth being difficult to clean.

[0011] 2. By adjusting the number of counterweights placed inside the counterweight box, the weight applied to the horizontal support rod by the counterweight box is changed, causing the center of gravity of the horizontal support rod to shift closer to the telescopic support rod. This avoids the telescopic support rod being subjected to excessive tilting force, which could lead to bending of the telescopic support rod or difficulty in clamping and fixing the mounting bracket.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a leg support device, including a telescopic support rod 1, a mounting bracket 101 fixedly connected to the lower end of the telescopic support rod 1, a horizontal support rod 102 fixedly connected to the upper end of the telescopic support rod 1, an adjusting block 103 slidably installed on the horizontal support rod 102, a hanging rope 104 fixedly connected to the lower end of the adjusting block 103, an arc-shaped support plate 3 fixedly connected to the other end of the hanging rope 104, a limiting protrusion 302 symmetrically fixed to the upper edge of the arc-shaped support plate 3, a supporting cotton cloth 4 provided inside the arc-shaped support plate 3, a connecting collar 401 embedded and installed inside the supporting cotton cloth 4 near the two side edges, the connecting collar 401 sleeved on the limiting protrusion 302, U-shaped locking blocks 5 installed on both sides of the arc-shaped support plate 3, and a counterweight box 2 fixedly connected to one end of the horizontal support rod 102.

[0016] In this implementation scheme, the telescopic support rod 1 can be fixed to the side of the bed using the mounting bracket 101. Then, the length of the telescopic support rod 1 is adjusted, thereby adjusting the height of the horizontal support rod 102, so that the arc-shaped support plate 3 is suspended at a suitable height. The connecting collar 401 is fitted into the limiting protrusion 302, and then the support cotton cloth 4 is installed and supported within the arc-shaped support plate 3. The patient's legs are placed on the support cotton cloth 4. The support cotton cloth 4 is made of highly breathable fabric. Firstly, its high breathability facilitates sweating and ventilation of the patient's skin; secondly, the fabric is soft, preventing pressure sores on the patient's legs. To improve patient comfort, the U-shaped locking block 5 is positioned at the edges of the curved support plate 3 on both sides, which can restrict the connecting collar 401 to the limiting protrusion 302. Later, the U-shaped locking block 5 can be removed to release the restriction on the connecting collar 401. At this time, the supporting cotton cloth 4 can be removed separately for cleaning and disinfection, avoiding the problem of dirt on the supporting cotton cloth 4 being difficult to clean. The telescopic support rod 1, mounting frame 101 and other components are existing mechanisms. For details, please refer to the clinical nursing leg support device disclosed in patent publication number CN222584881U, and will not be described in detail here.

[0017] In order to avoid bending of the telescopic support rod 1, the device adopts the following technical solution: a sealing door 201 is rotatably installed on one side of the counterweight box 2, and several counterweight blocks 202 are placed inside the counterweight box 2. The front and back of the arc-shaped support plate 3 are symmetrically fixed with connecting lugs 301, and the connecting lugs 301 are fixedly connected to the lifting rope 104.

[0018] By adjusting the number of counterweights 202 placed inside the counterweight box 2, the weight applied to the horizontal support rod 102 by the counterweight box 2 is changed. A certain amount of gravity can be applied to the other end of the horizontal support rod 102, causing the center of gravity of the horizontal support rod 102 to shift closer to the telescopic support rod 1. This avoids the telescopic support rod 1 being subjected to excessive tilting force, which could cause the telescopic support rod 1 to bend under force or make it difficult for the mounting bracket 101 to clamp and fix it. The telescopic support rod 1 should only bear the vertical downward force as much as possible. The sealing door 201 can seal the inside of the counterweight box 2, preventing dust from accumulating inside the counterweight box 2 or the counterweights 202 from falling off.

[0019] In order to achieve the purpose of fixing the connecting collar 401, the device adopts the following technical solution: the U-shaped block 5 is provided with several limiting holes 501, the limiting holes 501 and the limiting protrusions 302 cooperate with each other, the bottom of the U-shaped block 5 is fixedly connected with a return spring 502, and the other end of the return spring 502 is fixedly connected with a pressing plate 503.

[0020] The return spring 502 can provide a certain pushing force to the extrusion plate 503. The extrusion plate 503 contacts the lower edge of the arc-shaped support plate 3, thereby applying a certain downward force to the U-shaped block 5, so that the protrusion on the U-shaped block 5 fits against the arc-shaped support plate 3, and the limiting insertion hole 501 is sleeved on the limiting protrusion 302. When removing the U-shaped block 5, it is necessary to push the U-shaped block 5 upward to make the limiting insertion hole 501 disengage from the limiting protrusion 302. At this time, the U-shaped block 5 can move to the side and separate from the arc-shaped support plate 3, releasing the restriction on the connecting collar 401.

[0021] The working principle and usage process of this utility model are as follows: The telescopic support rod 1 can be fixed to the side of the bed using the mounting bracket 101. Then, the length of the telescopic support rod 1 is adjusted so that the arc-shaped support plate 3 is suspended at a suitable height. The patient's legs are placed on the support cotton cloth 4. The weight applied to the horizontal support rod 102 by the patient's legs is roughly estimated. The number of counterweights 202 placed inside the counterweight box 2 is adjusted to change the weight applied to the horizontal support rod 102 by the counterweight box 2, so that the overall center of gravity of the device is shifted closer to the telescopic support rod 1. When the support cotton cloth 4 needs to be cleaned later, the U-shaped locking block 5 is pushed upward to disengage the limiting insertion hole 501 from the limiting protrusion 302. At this time, the U-shaped locking block 5 can move to the side and separate from the arc-shaped support plate 3, releasing the restriction on the connecting collar 401. At this time, the support cotton cloth 4 can be removed separately for cleaning and disinfection.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
