Description

Technical Field

[0001] The utility model relates to the technical field of radial artery compression hemostasis, in particular to a radial artery compression device. Background Art

[0002] The radial artery compression device is a device used for hemostasis, mainly used in the medical field. Its principle is to compress the radial artery to stop blood flow, thereby reducing or stopping bleeding. The radial artery compression device is mainly composed of an adjustable wristband and a compression component, which can adapt to the wrist size of different patients. At the same time, the pressure applied to the radial artery can be adjusted as needed, ensuring the hemostasis effect without causing excessive compression or damage to the blood vessels and surrounding tissues.

[0003] In order to prevent the compression device from loosening and thus affecting the compression effect, patients are generally required not to turn their wrists at will after wearing the compression device. However, some patients still turn their wrists inadvertently, causing the binding state of the radial artery compression device to change, which is very likely to cause the compression pressure of the compression device on the radial artery to decrease, causing bleeding and other adverse effects.

[0004] To this end, the present application specifically proposes a radial artery compression device to solve the above technical problems. Utility Model Content

[0005] The main purpose of the utility model is to solve the above-mentioned shortcomings and provide a radial artery compression device, which can limit the wrist movement of the patient while wearing the compression device to prevent the compression device from loosening.

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] like Figure 1-6 As shown, the utility model provides a radial artery compression device, including a compression component 4 and a binding belt 5 provided at both ends of the compression component 4, and also includes:

[0027] A support plate 1, used for supporting the patient's forearm and palm;

[0028] Two binding components 2, which are adjustable in tightness and are arranged at both ends of the support plate 1, and are used to bind the patient's forearm and palm to the support plate 1;

[0029] The limiting components 3 are symmetrically arranged on both sides of the supporting plate 1 and are used to limit the relative position of the binding belt 5 on the supporting plate 1 .

[0030] When in use, first place the patient's forearm and palm on the support plate 1 with the palm facing up, then use the binding component 2 to bind the patient's forearm and palm to the support plate 1 to fix the patient's wrist, and then adjust the position of the strap 5 on the support plate 1 until the compression component 4 is aligned with the patient's radial artery wound, tighten the strap 5 and adjust the compression component 4 to apply pressure to the patient's radial artery wound, and finally adjust the limit component 3 to lock the relative position between the strap 5 and the support plate 1 to prevent the compression component 4 from moving.

[0031] In one embodiment, the strap 5 is inserted into the limiting assembly 3, and the limiting assembly 3 includes a limiting plate 31 fixedly arranged on both sides of the supporting plate 1 and a limiting block 32 inserted on the strap 5. The limiting plate 31 is provided with a long strip through hole 6 for inserting the strap 5, and the top surface of the limiting plate 31 is provided with a limiting groove 7 connected to the through hole 6. The side wall where the longer side of the limiting groove 7 is located is symmetrically provided with a first limiting tooth 8, and the two sides of the limiting block 32 are symmetrically provided with a second limiting tooth 9 meshing with the first limiting tooth 8.

[0032] The limit block 32 can slide along the strap 5. When the binding of the strap 5 and the pressure of the compression component 4 are completed, the limit block 32 is slid along the strap 5 until the limit block 32 is stuck in the limit groove 7, and the first limit tooth 8 and the second limit tooth 9 are engaged with each other. Due to the mutual blocking effect between the first limit tooth 8 and the second limit tooth 9, the limit block 32 cannot slide along the limit groove 7. Therefore, the strap 5 inserted in the limit block 32 cannot move along the direction of the limit groove 7, thereby locking the relative position of the strap 5 on the support plate 1. The compression component 4 arranged on the strap 5 is also more difficult to have relative displacement with the support plate 1, thereby improving the stability of the pressure applied by the compression component 4.

[0033] In one embodiment, the binding assembly 2 includes a threading assembly 21 fixedly disposed on the supporting plate 1 and a binding belt 22 threaded through the threading assembly 21 .

[0034] In one embodiment, the restraint belt 22 includes a contact portion 221 and connecting portions 222 disposed at two ends of the contact portion 221 , and the width of the contact portion 221 is greater than that of the connecting portion 222 .

[0035] The contact portion 221 is in direct contact with the patient's skin, so increasing its width can increase the contact area with the patient's skin and improve the stability of the binding.

[0036] In one embodiment, the threading assembly 21 includes two first threading blocks 211 symmetrically arranged at the bottom of the supporting plate 1 for threading one of the connecting parts 222 and a second threading block 212 fixedly arranged on one side of the supporting plate 1 for threading the other connecting part 222.

[0037] The first threading block 211 and the second threading block 212 provide fixing points for the restraint belt 22 and limit the tightening process of the restraint belt 22, so that the ends of the connecting portion 222 are easier to overlap during the tightening process, making the binding process of the restraint belt 22 more reliable and convenient.

[0038] In one embodiment, a ventilation hole 10 is provided on the contact portion 221. During the binding of the restraint belt 22, the contact portion 221 is in a ventilation state, which reduces the stuffiness of the contact portion between the patient's skin and the restraint belt 22 and optimizes the user experience.

[0039] In one embodiment, a non-slip rubber strip 11 is fixedly provided on one side of the contact portion 221 facing the support plate 1, thereby increasing the static friction coefficient between the binding belt 22 and the patient's skin, thereby preventing the binding belt 22 and the patient's skin from easily sliding relative to each other, and improving the stability of the binding assembly 2.

[0040] In one embodiment, the joint portion of the binding belt 5 and the binding belt 22 is configured as a Velcro structure, thereby simplifying the tightening and loosening operations of the binding belt 5 and the binding belt 22 and improving the convenience of use.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0042] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
