Description

Technical Field

[0001] The present invention relates to the technical field of limb fixation, and in particular to a limb restraint device. Background Art

[0002] When the patient is undergoing surgery in the supine position, if the patient's hands are not fixed during the operation, it is easy for the patient's hands to slip out of the operating table, causing the patient's hands to be easily injured by bumps and the like. In addition, some patients are prone to mania before or after the anesthetic effect ends. Therefore, according to various actual situations, it is necessary to fix the hands of some patients to prevent accidents.

[0003] Currently, the patient's hands are usually simply fixed on the operating table with bandages or hand pressure sheets. Although this can achieve a certain fixation effect, the bandages or hand pressure sheets will over-tighten the patient's hands, causing discomfort in the patients' hands. When the patients are unconscious and agitated, they will shake their hands vigorously, making it easy for the patients' hands to be strangled. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a limb restraint device to solve the above problems.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] The present invention provides a limb restraint device, comprising:

[0007] A pressure pad, with pads disposed on both sides of the top surface, wherein a channel is provided in the pad, and both ends of the channel are connected to the two outer sides of the pad;

[0008] A glove, one of which is disposed on each of the pads, one end of the glove being open and the inner wall of which is covered with an air bag cover;

[0009] A protective mechanism, one of which is provided for each of the two gloves, the protective mechanism comprising an air cylinder, a piston column and an air pipe, the air cylinder being installed on the operating table and having an open bottom, the piston column being slidably inserted at the top of the air cylinder, the bottom end of the piston column being located in the air cylinder and being provided with a piston sheet, the piston sheet being provided with a first one-way valve which only allows gas to enter the air cylinder, the top end of the piston column being located outside the air cylinder and being connected with a pulling rope, the distal end of the pulling rope passing through a channel and being connected with a corresponding glove, one end of the air pipe being connected to the top end of the air cylinder and being provided with a second one-way valve, the second one-way valve only allows gas to enter the air pipe from the air cylinder, and the other end of the air pipe being communicated with the corresponding air bag sleeve;

[0010] The resistance mechanism can drive the piston rod to move into the cylinder.

[0011] Furthermore, a plurality of fixing ropes are arranged on the edge of the pressure pad.

[0012] Furthermore, a leg cover is provided at the tail end of the top surface of the pressure pad, and a first zipper opening is provided in the middle of the leg cover.

[0013] Furthermore, the glove is provided with a second zipper opening, the airbag cover is provided with a through hole connected to the second zipper opening, a grip rod is installed inside the glove, and the side surface of the grip rod faces the second zipper opening.

[0014] Furthermore, a tightening belt is arranged around the surface of the glove.

[0015] Furthermore, a mounting block is provided on one side of the air cylinder, and a clamping sleeve is provided on the mounting block for clamping the legs of the operating bed, and a first stud is threadedly penetrated on one side of the clamping sleeve.

[0016] Furthermore, the resistance mechanism includes a mounting seat, an abutment rod and an elastic strip, the abutment rod is installed between the piston column and the pulling rope, the two mounting seats are installed on the top of the air cylinder and are respectively located on both sides of the abutment rod, the two mounting seats are provided with receiving grooves on one side facing each other, the elastic strip is located above the abutment rod, and its two ends extend into the two receiving grooves and are respectively connected to the bottom of the receiving grooves through springs.

[0017] Furthermore, mounting plates are respectively installed on both sides of the top of the air cylinder, and the top of each mounting plate has a plurality of thread grooves evenly distributed linearly along the length direction of the abutment rod, and a second stud adapted to the thread groove is rotatably installed on the mounting seat.

[0018] It can be seen from the above technical solution that the limb restraint device provided by the present invention:

[0019] 1. When the patient is in a calm state, the gloves will not over-tighten his hands, preventing the patient's hands from being strangled. Once the patient becomes agitated and shakes his hands, the pulling rope will be pulled together with the gloves, so that the piston column is pulled upward out of the air cylinder, and the gas is filled into the air bag sleeve, so that the air bag sleeve expands and presses against the patient's hand, strengthening the buffer between the patient's hand and the glove, and preventing the patient's hand from being strangled. At the same time, the resistance mechanism can drive the piston column to move into the air cylinder, thereby driving the piston plate to retreat to form a negative pressure in the air cylinder, and the external gas is replenished into the air cylinder through the first one-way valve, so that the piston column can be pulled out through the pulling rope every time the patient shakes his hands, and then the air bag sleeve is continuously inflated to enhance the protection effect. The resistance mechanism can also control the glove to drive the patient's hand back to the pad by driving the piston column back, and when the patient pulls the pulling rope, the piston plate squeezes the internal space of the air cylinder to generate resistance, which can consume the patient's physical strength and limit the movement of the patient's hand.

[0020] 2. Whenever the piston column is pulled out of the air cylinder, it will overcome the elastic force of the spring to push the elastic strip, thereby providing resistance to limit the swinging of the patient's hands. Whenever the patient is exhausted and relaxes his hands, the elastic strip will pull the piston column back into the air cylinder under the action of the elastic force of the spring. This cycle will be repeated, continuously consuming the patient's physical strength, prompting the patient to stop being restless, and at the same time, the gas in the air cylinder can be continuously replenished to ensure the gas supply of the airbag cuff. When the gas in the airbag cuff is gradually saturated, each subsequent pulling out of the piston column will generate greater pressure resistance in the air cylinder, making the piston column more difficult to pull, and gradually increasing the resistance when the patient swings his hands.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] like Figure 1-5 As shown, a limb restraint device provided in this embodiment includes a pressure pad 1, a glove 2, a protection mechanism 3 and a resistance mechanism 4.

[0036] See also Figure 1 and Figure 2 According to actual conditions, the pressure pad 1 can use a soft pad with high comfort or a hard pad with good fixing effect. Pads 11 are respectively arranged on both sides of the top surface of the pressure pad 1. The pads 11 have a certain weight and can use metal blocks or rubber blocks with high density. A channel 111 is opened in the pad 11, and the two ends of the channel 111 are respectively connected to the two outer sides of the pad 11.

[0037] Preferably, a plurality of fixing ropes 12 are provided on the edge of the pressure pad 1 to fix the edge of the pressure pad 1 to the side of the operating table, thereby improving the fixing effect of the pressure pad 1 .

[0038] One glove 2 is provided on each pad 11, one end of the glove 2 is open and the inner wall thereof is covered with an airbag cover 21. When the patient's hand is inserted into the glove 2, the airbag cover 21 can protect the patient's hand. When gas is filled into the airbag cover 21, the airbag cover 21 can expand and fit tightly against the patient's hand.

[0039] like Figure 1 As shown, preferably, a leg cover 13 is provided at the tail end of the top surface of the pressure pad 1, and a first zipper opening 131 is provided in the middle of the leg cover 13. The leg cover 13 can be opened by pulling the first zipper opening 131 to allow the patient's legs to be placed in. After the zipper is closed, the patient's legs can be wrapped in the leg cover 13 to limit the position of the patient's legs.

[0040] In one embodiment, a second zipper opening 22 is provided on the glove 2, and a hole 211 connected to the second zipper opening 22 is opened on the airbag cover 21. The back of the patient's hand can be exposed by opening the second zipper opening 22, which is convenient for puncturing the back of the patient's hand with a needle. A grip rod 23 is installed inside the glove 2, and the side of the grip rod 23 faces the second zipper opening 22. After the patient's hand is inserted into the glove 2, the patient's palm is buckled toward the grip rod 23, so that the back of the patient's hand can accurately face the second zipper opening 22.

[0041] Preferably, a tightening belt 24 is arranged around the surface of the glove 2. The tightening belt 24 can be a Velcro belt. When the patient's hand is inserted into the glove 2, the tightening belt 24 can be wrapped around the patient's wrist to prevent the patient's hand from slipping out.

[0042] See also Figure 1-Figure 4 , one protective mechanism 3 is respectively provided for two gloves 2, and the protective mechanism 3 comprises an air cylinder 31, a piston column 32 and an air pipe 33. The air cylinder 31 is installed on the operating bed and its bottom is open. The piston column 32 is slidably inserted at the top of the air cylinder 31, and the bottom end of the piston column 32 is located in the air cylinder 31 and is installed with a piston plate 321. The piston plate 321 is tightly fitted with the inner wall of the air cylinder 31, and a first one-way valve 322 is installed on the piston plate 321 for only allowing gas to enter the air cylinder 31. The top end of the piston column 32 is located outside the air cylinder 31 and is connected with a pulling rope 323. The distal end of the pulling rope 323 passes through the channel 111 and is connected to the corresponding glove 2. One end of the air pipe 33 is connected to the top of the air cylinder 31 and is installed with a second one-way valve 331. The second one-way valve 331 only allows gas to enter the air pipe 33 from the air cylinder 31, and the other end of the air pipe 33 is communicated with the corresponding air bag sleeve 21.

[0043] It should be noted that both the first one-way valve 322 and the second one-way valve 331 can be selected from existing technology products, and their specific structures are not described in detail.

[0044] The resistance mechanism 4 can drive the piston rod 32 to move into the air cylinder 31 .

[0045] When in use, the pressure pad 1 is placed on the operating table, and the patient lies on the pressure pad 1 and inserts both hands into the gloves 2 to fix them, so as to prevent the patient's hands from slipping out of the operating table during the operation. When the patient is in a calm state, the gloves 2 will not overly tighten the patient's hands, so as to prevent the patient's hands from being strangled. Once the patient becomes agitated and shakes his hands, the pulling rope 323 will be pulled together with the gloves 2, so that the piston column 32 is pulled upward out of the air cylinder 31, and the piston plate 321 compresses the internal gas of the air cylinder 31 into the air bag cover 21 through the second one-way valve 331 and the air pipe 33, so that the air bag cover 21 expands and presses against the patient's hands, thereby strengthening the buffer between the patient's hands and the gloves 2 and preventing the patient's hands from being strangled. Injury, at the same time, the resistance mechanism 4 can drive the piston column 32 to move into the air cylinder 31, thereby driving the piston plate 321 to retreat, so as to form a negative pressure in the air cylinder 31, and the external gas is replenished into the air cylinder 31 through the first one-way valve 322, so that the patient can pull out the piston column 32 through the pulling rope 323 every time the patient shakes his hand, and then continuously inflate the airbag sleeve 21 to enhance the protection effect, the resistance mechanism 4 can also control the glove 2 to drive the patient's hand back to the cushion block 11 by driving the piston column 32 to retreat, and when the patient pulls the pulling rope 323, the piston plate 321 squeezes the internal space of the air cylinder 31 to generate resistance, which can consume the patient's physical strength and limit the movement of the patient's hand.

[0046] like Figure 3 and Figure 4 As shown, specifically, a mounting block 311 is provided on one side of the gas cylinder 31, and a clamping sleeve 312 is provided on the mounting block 311. One side of the clamping sleeve 312 is U-shaped and is used to clamp the leg of the operating bed. A first stud 313 is threaded through one side of the clamping sleeve 312. By rotating the first stud 313, it can be moved closer to or away from one side of the leg of the operating bed to tighten or loosen the clamping sleeve 312 on the leg of the operating bed.

[0047] like Figure 3-Figure 4 As shown, in one embodiment, the resistance mechanism 4 includes a mounting seat 41, an abutment rod 42 and an elastic strip 43. The abutment rod 42 is installed between the piston column 32 and the pulling rope 323. The two mounting seats 41 are installed on the top of the air cylinder 31 and are respectively located on both sides of the abutment rod 42. The two mounting seats 41 are provided with a receiving groove 411 on the side facing each other. The elastic strip 43 can be an elastic metal strip. The elastic strip 43 is located above the abutment rod 42, and its two ends extend into the two receiving grooves 411 and are respectively connected to the bottom of the receiving groove 411 through springs 412. The spring 412 can provide an elastic force to pull the end of the elastic strip 43 into the receiving groove 411.

[0048] During specific use, each time the piston column 32 is pulled out of the air cylinder 31, it will overcome the elastic force of the spring 412 to push the elastic strip 43, thereby providing resistance to limit the swinging of the patient's hands. Whenever the patient is exhausted and relaxes his hands, the elastic strip 43 will pull the piston column 32 back into the air cylinder 31 under the action of the elastic force of the spring 412. This cycle is repeated again and again, continuously consuming the patient's physical strength, prompting the patient to stop being restless, and at the same time, the gas in the air cylinder 31 can be continuously replenished to ensure the gas supply of the airbag sleeve 21. When the gas amount in the airbag sleeve 21 is gradually saturated, each subsequent pulling out of the piston column 32 will generate a greater pressure resistance in the air cylinder 31, making the piston column 32 more difficult to be pulled, and the resistance when the patient swings his hands can be gradually increased.

[0049] Furthermore, mounting plates 314 are respectively installed on both sides of the top of the air cylinder 31, and a plurality of thread grooves 3141 are linearly and evenly distributed on the top of each mounting plate 314 along the length direction of the abutment rod 42. A second stud 413 adapted to the thread groove 3141 is rotatably installed on the mounting seat 41. Through the matching connection between the second stud 413 and the thread groove 3141, the mounting seat 41 can be detachably connected to the air cylinder 31, and then a plurality of pairs of mounting seats 41 and elastic strips 43 can be arranged, and the number of elastic strips 43 can be set according to the patient's strength and mania level to improve the restriction effect.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention 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 by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
