Description

Technical Field

[0001] The utility model relates to a hemostatic device, in particular to a pressurized hemostatic device for hemodialysis. Background Art

[0002] In clinical medicine, when the patient's hemodialysis treatment is completed, the patient's puncture site needs to be compressed to stop bleeding. The current method of compressing and stopping bleeding at the patient's puncture site is usually: first, press a gauze block on the puncture needle hole, and use a bandage to pressurize the gauze block to fix the gauze block on the puncture needle hole; then, according to the actual situation of the patient, compress the puncture site for bleeding for 20-30 minutes, then remove the bandage and gauze block, and finally observe that the puncture needle hole is no longer bleeding, and the compression and hemostasis operation is completed. However, the above-mentioned compression and hemostasis method has the following defects:

[0003] (1) The gauze piece and the bandage are both independent structures. When the gauze piece is bandaged and fixed with the bandage, it is easy to shift between the gauze piece and the bandage. If the gauze piece shifts to a position outside the puncture needle hole, it will seriously affect the effect of compression hemostasis;

[0004] (2) After applying pressure with a bandage, the pressure cannot be appropriately reduced according to the time of hemostasis before hemostasis is confirmed, which affects the patient's comfort;

[0005] (3) Doctors judge the time for compression hemostasis based on the table in the ward. However, when doctors are busy with work, they may easily forget to observe the compression hemostasis time of the patient, which will cause the compression hemostasis time to exceed the scheduled time. When the compression hemostasis time is too long, it is easy to cause the formation of fistula thrombosis. In severe cases, it may cause fistula occlusion, which will cause physical damage to the patient and seriously affect the safety of compression hemostasis. Summary of the invention

[0006] In order to solve the above deficiencies in the prior art, the utility model aims to provide a pressurized hemostasis device for hemodialysis, so as to achieve the purpose of improving the compression hemostasis effect, improving the patient's comfort and improving the safety of compression hemostasis.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a pressurized hemostatic device for hemodialysis, comprising an adhesive mechanism that can be attached to human skin, a disinfection hemostatic mechanism fixed at the bottom of the adhesive mechanism, an adjustment mechanism fixed at the top of the adhesive mechanism that can adjust the pressure of pressing the adhesive mechanism, and a timing reminder mechanism fixed on the adjustment mechanism.

[0008] As a limitation of the present utility model, the adhesive mechanism includes a flexible connecting sheet and a flexible adhesive sheet detachably connected to the bottom of the flexible connecting sheet; the disinfection and hemostasis mechanism is fixedly arranged at the bottom of the flexible adhesive sheet.

[0009] As a further limitation of the present invention, the flexible connecting sheet is provided with a plurality of grooves, and a limiting protrusion adapted to the grooves is respectively provided at positions corresponding to the plurality of grooves on the flexible adhesive sheet so that the flexible adhesive sheet can be firmly clipped on the flexible connecting sheet.

[0010] As a further definition of the present utility model, the adjustment mechanism includes a shell fixed on the top of the flexible connecting piece, a threaded rod threadedly connected to the shell, a pressing member rotatably arranged at the bottom of the threaded rod and located in the shell cavity, and a rotating handle fixed on the top of the threaded rod and located on the outside of the shell.

[0011] As a further limitation of the present invention, the disinfection and hemostasis mechanism is a sterile disinfection cotton sheet.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0013] (1) The utility model adopts a structural form that combines an adhesive mechanism, a disinfection hemostasis mechanism, an adjustment mechanism and a timing reminder mechanism. The adhesive mechanism can firmly fix the disinfection hemostasis mechanism on the patient's puncture site, which can improve the accuracy of the compression position of the utility model, and thus effectively improve the compression hemostasis effect of the utility model; the adjustment mechanism can adjust the size of the pressure applied to the adhesive mechanism, thereby adjusting the pressure of the disinfection hemostasis mechanism on the patient's puncture site. During actual use, the pressure of the puncture site can be adaptively adjusted according to the patient's condition, which can effectively improve the patient's comfort; the timing reminder mechanism can alarm and remind according to the preset time. When the compression hemostasis time reaches the preset time, the timing reminder mechanism can make a sound to remind the doctor, so as to avoid the compression hemostasis time being too long and causing damage to the patient's body, which can effectively improve the safety of compression hemostasis.

[0014] (2) The flexible connecting sheet and the flexible adhesive sheet in the utility model are detachably connected by means of the engagement of the groove and the limiting protrusion. When the compression hemostasis operation is completed, there is no need to replace the entire piece. The flexible adhesive sheet and the disinfection hemostasis mechanism only need to be removed from the utility model and replaced with a new flexible adhesive sheet and disinfection hemostasis mechanism, which can reduce the cost of use. In addition, the material of the flexible connecting sheet and the flexible adhesive sheet in the utility model is soft, and they are highly comfortable when in contact with human skin, which can improve the comfort of patients when using the device.

[0015] (3) The adjustment mechanism of the utility model has a simple structure and is easy to operate. The pressing member can be moved upward or downward by rotating the handle by hand. The pressure of the pressing and pasting mechanism can be adjusted by adjusting the distance that the pressing member moves upward or downward.

[0016] (4) The disinfection and hemostasis mechanism of the present invention adopts the existing sterile disinfection cotton pad, which has low cost and good disinfection and hemostasis effect, and can effectively improve the compression and hemostasis effect of the present invention.

[0017] In summary, the utility model has a simple structure, low manufacturing cost, convenient use and strong practicality. The disinfection hemostasis mechanism can be firmly fixed on the patient's puncture site, the adjustment mechanism can adjust the pressure applied to the sticking mechanism, and the timing reminder mechanism can alarm and remind according to the preset time. While effectively improving the compression hemostasis effect of the utility model, it can also effectively improve the comfort and safety of use. The utility model is suitable for use in compression hemostasis of the puncture site after hemodialysis. BRIEF DESCRIPTION OF THE DRAWINGS
