[0002] At present, percutaneous puncture via the brachial artery for cardiac intervention is becoming increasingly common. After the operation, after using an elastic bandage to compress and bandage the surgical wound of the patient, a simple hard cardboard or other rigid materials are commonly used and padded under the surgical limb, and finally multiple layers of adhesive tapes are used for winding and fixing. The fixing property and comfort are poor, and the patient often unconsciously moves or bends the surgical limb, thereby causing postoperative complications such as hematoma and pseudoaneurysm. Content of the Utility Model

[0003] The purpose of the utility model is to provide a puncture fixing device for the brachial artery to solve the technical problems in the prior art that the fixing property and comfort of the patient's surgical limb are poor and postoperative complications are likely to occur.

[0004] The technical solution adopted to solve the above technical problems:

[0005] The utility model discloses a puncture fixing device for the brachial artery, which includes an upper arm loop, a forearm loop and a fixing member. The upper arm loop and the forearm loop are both provided with openings, and at least one fixing member is provided at each of the two openings. The upper arm loop and the forearm loop are connected at an angle and a through hole is formed at the connection.

[0006] The utility model has at least the following beneficial effects: After the operation, the patient can fix the surgical limb through the puncture fixing device for the brachial artery. The upper arm of the patient's surgical limb can pass through the opening and into the upper arm loop, and the forearm of the patient's surgical limb can pass through the opening and into the forearm loop, and are respectively fixed by at least one fixing member to prevent the surgical limb from detaching from the opening. The upper arm loop and the forearm loop are connected at an angle to make the angle between the patient's upper arm and forearm located therein relatively fixed, prevent the patient from moving or bending the surgical limb, and avoid postoperative complications of the patient. A through hole is provided at the connection of the upper arm loop and the forearm loop, and the elbow joint can pass through the through hole to avoid the protruding elbow joint pressing against the inner side of the puncture fixing device for the brachial artery, thereby improving the comfort of the patient's use.

[0007] As a further improvement of the above technical solution, the fixing member includes a first connecting member and a second connecting member that are detachably connected, and the first connecting member and the second connecting member are respectively connected to opposite sides of the opening.

[0008] Through the above setting, the first connecting member and the second connecting member are detachably connected, so that the connection and disconnection between the two are more convenient. The first connecting member and the second connecting member are detached from each other, and the patient's surgical limb can pass through the opening and into the puncture fixing device for the brachial artery. The first connecting member and the second connecting member are connected to each other, and the patient's surgical limb can be firmly restricted within the upper arm loop and the forearm loop.

[0009] As a further improvement of the above technical solution, the first connecting member is a bar buckle, the second connecting member is a clip, and the bar buckle can be inserted and connected to the clip.

[0010] With the above arrangement, the insertion length of the bar buckle can be adjusted according to the thickness of the patient's operative limb to adjust the tightness of the connection between the patient's operative limb and the transbrachial artery puncture fixation device. The inserted bar buckle can also be pulled out by pressing the clip, which is convenient for disassembly.

[0011] As a further improvement of the above technical solution, the included angle range between the upper arm loop and the forearm loop is 165° - 180°.

[0012] With the above arrangement, it can avoid excessive bending of the patient's operative limb, help maintain the normal functions of the upper arm and forearm, and keep the comfort of the operative limb.

[0013] As a further improvement of the above technical solution, the included angle between the upper arm loop and the forearm loop is 170°.

[0014] With the above arrangement, the supplementary angle of the carrying angle between the upper arm and the forearm of the patient's operative limb can be 10 degrees, enabling the transbrachial artery puncture fixation device to meet the needs of most men and women, improving the applicability. Moreover, it can keep the patient's operative limb in a slightly bent state, avoiding the fatigue caused by the straight state of the operative limb.

[0015] As a further improvement of the above technical solution, the cross-sections of both the upper arm loop and the forearm loop are C-shaped.

[0016] With the above arrangement, the C-shaped upper arm loop and forearm loop of the transbrachial artery puncture fixation device can make the device fit better with the shape of the patient's operative limb, providing better support and stability for the patient's operative limb.

[0017] As a further improvement of the above technical solution, soft pads are provided on the inner sides of both the upper arm loop and the forearm loop.

[0018] With the above arrangement, the soft pads can protect the patient's skin and buffer the muscles of the patient's operative limb, avoiding pressure injuries of the operative limb and reducing the occurrence of adverse effects such as hematomas.

[0019] As a further improvement of the above technical solution, the soft pads are also provided on the inner side of the fixing member.

[0020] With the above arrangement, a soft pad is provided on the side of the fixing member that fits the patient's operative limb, further improving the comfort of the patient's operative limb.

[0021] As a further improvement of the above technical solution, the upper arm loop and the forearm loop are integrally formed.

[0022] With the above settings, the upper arm loop and the forearm loop are integrally formed and fixed, improving the structural stability and reducing the possibility of deformation and fragmentation of the transbrachial artery puncture fixation device.

[0023] As a further improvement of the above technical solution, both the upper arm loop and the forearm loop are plastic parts.

[0024] With the above settings, the material cost of the transbrachial artery puncture fixation device is reduced, the weight is light, it does not affect the patient's postoperative activities, and it can be reused after disinfection. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Refer to Figure 1 and Figure 2 , the following gives several embodiments of the brachial artery puncture fixation device of the present utility model.

[0042] As Figure 1 and Figure 2 shown, the brachial artery puncture fixation device 100 of the embodiment of the present utility model includes an upper arm cuff 200, a forearm cuff 300 and a fixing member 400.

[0043] It can be understood that both the upper arm cuff 200 and the forearm cuff 300 are provided with openings. Specifically, the openings include a first opening 210 and a second opening 310. The first opening 210 is provided on the upper arm cuff 200, and the upper arm of the patient's operative limb can be placed in the upper arm cuff 200 through the first opening 210 to restrict the upper arm of the patient's operative limb through the upper arm cuff 200. The second opening 310 is provided on the forearm cuff 300, and the forearm of the patient's operative limb can be placed in the forearm cuff 300 through the second opening 310 to restrict the forearm of the patient's operative limb through the forearm cuff 300.

[0044] It can be understood that at least one fixing member 400 is provided at the first opening 210. The fixing member 400 is used to firmly fix the upper arm of the patient's operative limb in the upper arm cuff 200 to prevent the upper arm of the patient from detaching from the upper arm cuff 200 through the first opening 210, such asFigure 1 and Figure 2 as shown

[0045] Similarly, at least one fixing member 400 is also provided at the second opening 310 to firmly fix the forearm of the patient's operative limb within the forearm loop 300, preventing the patient's forearm from detaching from the forearm loop 300 through the second opening 310, as Figure 1 and Figure 2 shown

[0046] It can be understood that the upper arm loop 200 and the forearm loop 300 are connected to each other and are arranged at an angle, so that the upper arm and the forearm of the patient's operative limb are placed at an angle, restricting the bending range of the upper arm and the forearm, and preventing the situation that the upper limb of the patient causes postoperative complications due to excessive bending

[0047] It can be understood that since the upper arm loop 200 and the forearm loop 300 are connected to each other, the first opening 210 and the second opening 310 are in communication with each other

[0048] It can be understood that a through hole 500 is formed at the connection between the upper arm loop 200 and the forearm loop 300, and the through hole 500 conducts the outer side and the inner side of the brachial artery puncture fixing device 100, as Figure 1 shown. When the upper limb of the patient is placed on the brachial artery puncture fixing device 100, the patient's elbow joint corresponds to the through hole 500 and can pass through the through hole 500, improving the comfort of the patient's use and preventing the raised elbow joint of the patient from pressing against the inner side of the brachial artery puncture fixing device 100, resulting in discomfort, pain and other symptoms in the patient's elbow joint

[0049] It can be understood that the fixing member 400 includes a first connecting member and a second connecting member, and the first connecting member and the second connecting member are detachably connected. The first connecting member and the second connecting member are respectively connected to opposite sides of the opening. Specifically, taking the upper arm loop 200 as an example, the first connecting member is connected to one side of the first opening 210, and the second connecting member is connected to the opposite side of the first opening 210. After the upper arm of the patient is placed into the upper arm loop 200, the first connecting member and the second connecting member are connected to each other, realizing the firm connection between the patient's postoperative upper arm and the upper arm loop 200, and the connection is simple

[0050] Similarly, at least one first connecting member and one second connecting member are respectively connected to opposite sides of the second opening 310. After the forearm of the patient is placed into the forearm loop 300, the first connecting member and the second connecting member are connected, so that the forearm of the patient is firmly connected to the forearm loop 300

[0051] It can be understood that when the brachial artery puncture fixing device 100 needs to be removed, only by detaching the first connecting member and the second connecting member from each other, the operative limb of the patient can be taken out from the first opening 210 and the second opening 310, and the disassembly is convenient

[0052] It is understandable that the upper arm loop 200 and the forearm loop 300 may each be provided with one or more fixing members 400. In this embodiment, the upper arm loop 200 and the forearm loop 300 are each provided with one fixing member 400 to reduce the setting cost of the fixing member 400.

[0053] In some embodiments, both the first connecting member and the second connecting member are straps, and the detachable connection between the brachial artery puncture fixing device 100 and the patient's operative limb can be realized by a detachable manner of tying and untying. However, the disassembly and assembly are inconvenient, and the strap becomes thinner at the place of tying connection, which is likely to cause injury to the patient's operative limb.

[0054] In some other embodiments, the first connecting member is a male magic tape and the second connecting member is a female magic tape, and the detachable connection between the brachial artery puncture fixing device 100 and the patient's operative limb is realized by a detachable bonding method. However, one of the bonding surfaces of the male magic tape or the female magic tape will contact the skin surface of the patient. If it is the hooked bonding surface, it is likely to affect the patient's use experience. After long-term use, the hooked bonding surface is likely to adhere to too many sundries, and the hair on the soft bonding surface is likely to fall off, resulting in the male magic tape and the female magic tape no longer adhering, and the brachial artery puncture fixing device 100 is difficult to connect and fix the patient's operative limb again.

[0055] In this embodiment, the first connecting member is a bar buckle 410 and the second connecting member is a buckle clip 420. Specifically, one end of the bar buckle 410 is connected to one side of the opening, the buckle clip 420 is connected to the other side of the opening, the bar buckle 410 has a rack 411, the rack 411 is inserted into the buckle clip 420 and is clamped and fixed by the buckle clip 420, so that the patient's operative limb is stably placed in the brachial artery puncture fixing device 100, as Figure 1 and Figure 2 shown.

[0056] With such a setting, when the bar buckle 410 is connected to the buckle clip 420, the inner side of the rack 411 contacts the patient's skin, and the width of the rack 411 is fixed to ensure the patient's use experience. The bar buckle 410 and the buckle clip 420 are firmly connected, and it is not easy to cause the connection to become loose or the structure to deform due to being stretched, and the service life is long.

[0057] It is understandable that when the patient's operative limb needs to be taken out, the buckle clip 420 can be directly pressed to pull the rack 411 of the bar buckle 410 out of the buckle clip 420, and the operative limb can be taken out from the first opening 210 and the second opening 310.

[0058] It is understandable that the bar buckle 410 can adjust the position of the rack 411 inserted into the buckle clip 420 according to the thickness of the patient's operative limb, and further adjust the tightness to avoid the loosening of the connection between the patient's operative limb and the brachial artery puncture fixing device 100.

[0059] It can be understood that, in order to avoid postoperative complications caused by excessive bending of the patient's operative limb, the brachial artery puncture fixation device 100 should keep the patient's operative limb in a straight or slightly bent state.

[0060] In this regard, the included angle range between the upper arm loop 200 and the forearm loop 300 is 165 degrees to 180 degrees. Specifically, the upper arm loop 200 is provided with a first axis along the extending direction, and the forearm loop 300 is provided with a second axis along the extending direction. The included angle range between the first axis and the second axis is 165 degrees to 185 degrees.

[0061] With such a setting, when the patient's upper arm is placed in the upper arm loop 200 and the forearm is placed in the forearm loop 300, the included angle range formed by the extension line of the patient's upper arm and the extension line of the forearm is between 165 degrees and 180 degrees. At this time, the supplementary angle of the carrying angle between the patient's upper arm and forearm is between 0 degrees and 15 degrees, which helps to maintain the normal functions of the upper arm and forearm and keep the comfort of the operative limb.

[0062] It can be understood that the supplementary angle range of the male carrying angle is generally between 5 degrees and 10 degrees, and the supplementary angle range of the female carrying angle is generally between 10 degrees and 15 degrees.

[0063] In this regard, the included angle between the upper arm loop 200 and the forearm loop 300 is 170 degrees. When the patient wears it, the supplementary angle of the carrying angle between the patient's upper arm and forearm is 10 degrees, so that the brachial artery puncture fixation device 100 can be applicable to most men and women at the same time, increasing the applicability of the brachial artery puncture fixation device 100. Moreover, the patient's upper arm and forearm can maintain a slightly bent state, avoiding fatigue caused by the straightening of the operative limb.

[0064] It can be understood that the cross-section of the upper arm loop 200 is C-shaped, and the cross-section of the forearm loop 300 is also C-shaped. Therefore, the inner C-shaped shape of the brachial artery puncture fixation device 100 fits better with the shape of the patient's operative limb to better support and stabilize the patient's operative limb. The outer C-shaped shape of the brachial artery puncture fixation device 100 can reduce the material cost required for production and is convenient for the patient to place the operative limb on the armrest or tabletop.

[0065] In this embodiment, both the first opening 210 and the second opening 310 are arranged upward, so that the patient's operative limb can be inserted into the brachial artery puncture fixation device 100 from top to bottom, and the patient's operative wound is exposed at the first opening 210, facilitating medical staff to observe the operative wound through the first opening 210.

[0066] It can be understood that the C-shaped upper arm loop 200 and the C-shaped forearm loop 300 are semi-circular rings, so that the brachial artery puncture fixation device 100 only wraps the lower half of the patient's operative limb, facilitating the insertion and removal of the patient's operative limb.

[0067] It can be understood that, in order to improve the comfort of the patient's operative limb, a soft pad 600 is provided on the inner side of the transbrachial artery puncture fixing device 100. As Figure 1 and Figure 2 shown, the patient's skin contacts with the soft pad 600, which not only protects the patient's skin, but also avoids pressure injury of the operative limb, and reduces the hematoma caused by poor fixation of the patient's operative limb. Specifically, a soft pad 600 is provided on the inner side of the upper arm loop 200, and a soft pad 600 is also provided on the inner side of the forearm loop 300 to buffer and support the upper arm and forearm of the patient's operative limb respectively.

[0068] It can be understood that, taking the upper arm loop 200 as an example, one or more soft pads 600 can be provided on the inner side of the upper arm loop 200. When multiple soft pads 600 are provided, two adjacent soft pads 600 are arranged at intervals and a flow groove 700 is formed. Air can flow in the flow groove 700 to avoid the operative limb of the patient from being stuffy, as Figure 1 and Figure 2 shown. Similarly, when multiple soft pads 600 are provided on the inner side of the forearm loop 300, two adjacent soft pads 600 are arranged at intervals.

[0069] It can be understood that the soft pads 600 located on the upper arm loop 200 and the soft pads 600 located on the forearm loop 300 that are adjacent to each other are arranged at intervals to further increase air conduction and avoid skin stuffiness.

[0070] In this embodiment, the extension length of the forearm loop 300 is greater than the extension length of the upper arm loop 200. Two soft pads 600 arranged at intervals are provided on the inner side of the forearm loop 300, and one soft pad 600 is provided on the inner side of the upper arm loop 200.

[0071] It can be understood that a soft pad 600 is also provided on the inner side of the fixing member 400, so that when the fixing member 400 fixes the patient's operative limb and the transbrachial artery puncture fixing device 100, the soft pad 600 located on the inner side of the fixing member 400 can further increase the comfort of the patient.

[0072] In this embodiment, the side of the rack 411 with teeth is arranged away from the inner side of the transbrachial artery puncture fixing device 100, and the soft pad 600 is arranged on the side of the rack 411 facing the inner side of the transbrachial artery puncture fixing device 100.

[0073] It can be understood that the soft pad 600 can be a cotton pad, a silicone pad or an airbag pad, etc. The cotton pad is simple to manufacture, disposable, convenient and hygienic. The silicone pad and the airbag pad can be reused after disinfection, reducing the use cost.

[0074] In this embodiment, the soft pad 600 is a silicone pad, and the silicone pad can be disinfected by means of alcohol, 84 disinfectant or heating, etc. for recycling use.

[0075] It can be understood that the silicone pad can be fixedly connected to the inner sides of the upper arm loop 200, the forearm loop 300, and the fixing member 400 respectively by means of bonding, screws, etc., or can be detachably connected by connecting structures such as Velcro, magnets, etc., so as to facilitate the removal of the silicone pad for special cleaning.

[0076] It can be understood that the upper arm loop 200 and the forearm loop 300 are integrally formed so that the upper arm loop 200 and the forearm loop 300 are connected and fixed and the structure is coherent, which is convenient for the production and manufacture of the brachial artery puncture fixing device 100 and simplifies the assembly work.

[0077] In some embodiments, both the upper arm loop 200 and the forearm loop 300 are made of metal to improve the structural stability of the upper arm loop 200 and the forearm loop 300 and reduce the possibility of deformation, fragmentation, etc. of the brachial artery puncture fixing device 100.

[0078] In this embodiment, both the upper arm loop 200 and the forearm loop 300 are made of plastic to save the material cost of the upper arm loop 200 and the forearm loop 300; the plastic is lighter in weight and does not affect the postoperative activities of the patient; the plastic has good wear resistance and impact resistance, is not easily damaged by bumps, and can be used repeatedly.

[0079] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
