Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an adjustable hemostatic compressor. Background Art

[0002] The main function of the hemostatic compressor is to prevent massive bleeding after surgery or trauma, which is particularly important for patients who need to stay in bed for a long time. It can reduce the need for blood transfusion, lower the surgical risk, and promote wound healing. Its common structure includes a bottom plate, a lifting bracket, and a pressing rod. The plastic pressing head on the pressing rod is adjusted to press on the arterial puncture site, applying sufficient pressure to prevent bleeding while maintaining a weak pulsation of the dorsalis pedis artery. It can be seen in the published application document CN214761284U, which includes a compressor main body. A regulating bolt is provided at the center of the end face of the compressor main body. A pressure detection component is provided at the bottom of the regulating bolt, and a replaceable pressing structure is provided at the bottom of the pressure detection component. In the present utility model, through the pressure sensor provided, the magnitude of the pressure exerted by the hemostatic compressor on the patient is sensed, and the pressing force of the hemostatic compressor can be adjusted more intuitively, thus solving the problem that in the existing hemostatic compressor during use, medical staff cannot intuitively understand the force they exert on the patient. If the force is too small, it cannot play a hemostatic role, and if the force is too large, it is likely to cause blood circulation problems and further harm to the patient. However, during use, there is a situation where the callback of the regulating bolt to the initial state is slow, that is, it must be slowly adjusted by medical staff, increasing inconvenience. Summary of the Invention

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1:

[0027] As Figures 1-5 shown, the embodiment of the present invention provides an adjustable hemostatic compressor, including a base 1. A fixing belt 3 is provided on one side of the base 1. Specifically, side rings 2 are provided at both ends of the base 1. One end of the fixing belt 3 passes through the inside of one of the side rings 2 and is fixed in a ring shape. The other end of the fixing belt 3 passes through the other side ring 2 and is connected by a provided magic tape to form a ring structure combined with the base 1. During use, first place the base 1 at the part of the patient that needs hemostasis, and then use the fixing belt 3 to tie and fix the hemostatic part of the patient. During the process, the end of the fixing belt 3 far from the ring-shaped fixing passes through the other side ring 2 relative to the ring-shaped fixing of the connecting fixing belt 3 and is fixed by the included magic tape. The sticking length of the magic tape can be adjusted as needed, thereby realizing the pre-adjustment of the fixing degree;

[0028] The upper side surface of the base 1 is fixedly connected with an outer seat 6 with an open lower part. The side wall of the outer seat 6 is slidably connected with an outer cylinder 8 and a pressure rod 9. The outer cylinder 8 and the pressure rod 9 are vertically moved up and down relative to the outer seat 6 by arranging corresponding sliding grooves on the outer seat 6 and fixedly connecting sliders corresponding to the sliding grooves on the outer doors of the outer cylinder 8 and the pressure rod 9. The above-mentioned sliding grooves and sliders are not shown in the drawings. The outer side surface of the outer cylinder 8 is fixedly connected with a fixed block 15. The upper side surface of the base 1 is fixedly connected with a pressing block 14 located inside the outer seat 6. A spring 16 is fixedly connected between the base 1 and the outer cylinder 8. The fixed block 15 is in inclined surface cooperation with the pressing block 14 and at this time the spring 16 is in a compressed state. The inclined surface of the fixed block 15 cooperating with the pressing block 14 faces a corner of the outer seat 6 close to the pressure rod 9. In the above, the pressing block 14 presses the fixed block 15, thereby making the spring 16 in a compressed state;

[0029] The inner part of the outer cylinder 8 is threadedly connected with an adjusting knob 7. The lower end of the adjusting knob 7 passes through the base 1 and a pressing plate 4 is fixedly connected to one end located below the base 1. In the above, by rotating the adjusting knob 7, the pressing plate 4 can be driven to move downward, thereby pressing the part of the patient that needs to stop bleeding;

[0030] The lower end of the pressure rod 9 located inside the outer seat 6 is fixedly connected with a wedge block 13. The wedge block 13 is used to push the pressing block 14 away from the fixed block 15 after being pressed downward. In the above, after the pressure rod 9 is pressed downward, the fixed block 15 squeezes the pressing block 14, thereby realizing the separation of the pressing block 14 and the fixed block 15. In this case, due to the elastic force of the spring 16, the outer cylinder 8 is pushed upward. During the process, the outer cylinder 8 drives the adjusting knob 7 to move upward through thread self-locking, thereby driving the pressing plate 4 to move upward and away from the part of the patient that needs to stop bleeding.

[0031] The upper side wall of the outer seat 6 is fixedly connected with a one-way valve port 5. The lower side surface of the base 1 and located outside the pressing plate 4 is fixedly connected with an airbag ring 10. The airbag ring 10 is pipe-connected with the one-way valve port 5. In the above, by manually pressing the airbag to connect with the one-way valve port 5, the airbag ring 10 is inflated.

[0032] Embodiment Two:

[0033] The difference between this embodiment and the first embodiment is as follows: A communication hole communicating with the inside of the airbag ring 10 penetrates through the base 1. A connecting rod 12 is fixedly connected to the lower side of the wedge block 13. The lower end of the connecting rod 12 is fixedly connected to a plug block 11. The connecting rod 12 passes through the communication hole. The plug block 11 is located inside the airbag ring 10. During the downward movement of the pressing rod 9, the wedge block 13 is driven to move the connecting rod 12 downward, driving the plug block 11 to open the communication hole of the airbag ring 10, thereby discharging the air inside the airbag ring 10. After pressing the adjustment knob 7 downward and pulling the pressing rod 9, when the pressing block 14 and the fixed block 15 are in a matching state, the plug block 11 blocks the communication hole again. At this time, the airbag can be manually pressed from the one-way valve port 5 to inflate the airbag ring 10.

[0034] The plug block 11 includes a blocking portion with a diameter larger than that of the communication hole. The portion of the blocking portion connecting the connecting rod 12 includes a convex platform that can pass through the airbag ring 10.

[0035] The fixing belt 3 is made of nylon material. The base 1, the outer seat 6, and the pressing block 14 are all made of medical PP plastic.

[0036] The vertical portion of the pressing block 14 connected to the base 1 is inclined, and the inclination direction deviates from the outer cylinder 8.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
