Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a rapid hemostasis device for emergency surgery. Background Art

[0002] Surgical hemostasis methods usually include compression hemostasis and suturing hemostasis. In emergency surgery, rapid hemostasis of wounds is usually required. Therefore, compression hemostasis has become the most common hemostasis method in emergency surgery.

[0003] However, the existing emergency surgical hemostasis devices have the following problems during use:

[0004] For example, a Chinese utility model patent (CN219700024U) discloses an "emergency rapid hemostasis device," which specifically discloses: a hemostasis box, with bandages fixedly sewn on both sides of the hemostasis box, an extrusion assembly provided inside the hemostasis box, the extrusion assembly including an adjustment slot, a threaded rod rotatably connected to the interior of the adjustment slot, a threaded block provided on the upper sleeve of the threaded rod, a connecting rod fixedly connected at both ends of the bottom of the threaded block, and a hemostasis block fixedly connected to the bottom end of the connecting rod, which can adjust the position of the hemostasis block, thereby facilitating control of the extrusion force of the extrusion block on the wound, avoiding excessive extrusion, and enhancing the patient's comfort during treatment and the protection of the wound;

[0005] Although the above-mentioned rapid hemostasis device can achieve rapid hemostasis of the wound and avoid excessive squeezing, the wound position, direction and size of the wound of the injured patients admitted to the emergency surgery department are uncertain. Therefore, a single hemostasis device cannot fully cope with the above-mentioned situation, making it impossible to achieve precise compression and hemostasis of the patient's wound. Therefore, people urgently need a rapid hemostasis device that can adjust the hemostasis device according to the direction of the wound to achieve precise compression of the wound to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a rapid hemostasis device for emergency surgery to solve the problems raised in the prior art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a rapid hemostasis device for emergency surgery, comprising a shell and a strap, the interior of the shell being hollow, the shell and the strap being connected by a quick-release structure, a horizontally rotatable compression piece being provided inside the shell, the compression piece being in the shape of an elongated strip, and being adjusted and rotated by a rotating structure to adapt to wounds with uncertain directions.

[0008] Preferably, the compression member is a compression airbag, which compresses the wound and stops bleeding by expanding the compression airbag with air. The compression airbag is installed on a rotating plate, and the rotating structure passes through the top of the shell and is detachably connected to the rotating plate. The rotating structure is connected to a power supply airbag through a hose. After the rotating structure is connected to the rotating plate, the compression airbag is connected to the power supply airbag, and air is supplied to the compression airbag through the power supply airbag.

[0009] Preferably, a mounting seat is provided on the top of the shell, and a hole penetrating the shell is provided at the bottom of the mounting seat;

[0010] The rotating shaft of the rotating structure passes through the hole vertically and is connected to the housing and the pressing member through a threaded connection. A sealing plate is provided at the top of the rotating shaft, and a rotating knob is installed on the sealing plate. The rotation of the rotating knob is used to adjust the rotation of the pressing member.

[0011] The rotating shaft, the sealing plate and the middle portion of the rotating knob are connected through to form an air flow hole, and the air flow hole is connected to the hose.

[0012] Preferably, a connecting seat is provided on the top of the rotating plate, a threaded hole is provided in the middle of the connecting seat, the rotating shaft and the connecting seat are detachably connected via threads, a rotating ring is provided on the periphery of the threaded hole, and a plurality of equally spaced limiting holes are provided at the bottom of the rotating ring;

[0013] The bottom edge of the hole is provided with a plurality of plug-in parts that match the limiting holes, and the plug-in parts are fixedly mounted on the housing;

[0014] When the sealing plate is located at the top of the mounting seat, the connector is inserted into the limiting hole to fix the position of the pressing member;

[0015] When the sealing plate is pressed downward inside the mounting seat, the pressing member moves downward under the action of the rotating shaft, and the plug-in member is separated from the limiting hole.

[0016] Preferably, a plurality of silicone sealing rings are vertically arranged and embedded in the inner wall of the mounting seat, and the distance between two adjacent silicone sealing rings is at least greater than the thickness of the sealing plate.

[0017] Preferably, the cross-section of the shell is in the positive direction, and extrusion airbags are provided on all four sides of the inner wall of the shell. The length of the compression member is less than the inner side length of the shell and greater than the minimum distance between two non-adjacent extrusion airbags. Atomizing nozzles are provided at all four corners of the inner wall of the shell. The atomizing nozzles are connected to the extrusion airbags and are equipped with a one-way valve so that the medium can only flow from the extrusion airbags to the atomizing nozzles.

[0018] Preferably, a liquid storage cavity is provided at the top of the shell, and an injection port for injecting the medium into the liquid storage cavity is provided. The liquid storage cavity is connected to the extrusion airbag, and a one-way valve is installed so that the medium can only flow from the liquid storage cavity to the extrusion airbag.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The rapid hemostasis device of the present invention can be adjusted according to the position and direction of the patient's wound. The long compression piece design allows for precise compression and hemostasis of the wound. At the same time, the rotatable design of the compression piece allows the rapid hemostasis device to adapt to different wound directions. Moreover, the force generated during the rotation of the compression piece can be used to atomize and spray medical alcohol to sterilize and disinfect the compression piece itself, killing two birds with one stone.

[0024] 2. The present invention designs the rotating structure and the compression member to be a detachable structure, so that when the rapid hemostasis device is used for a long time, only the compression member can be replaced without replacing the entire hemostasis device, which can save more costs.

[0025] 3. The present invention uses the connector and the limiting hole, and the position of the compression piece can only be adjusted after pressing the rotating structure. After the adjustment is completed, the rotating structure can be manually lifted to fix the position of the compression piece. The rotating structure can also be automatically lifted up when the compression piece compresses the wound to stop bleeding, thereby playing a role of limiting and fixing, avoiding the displacement of the compression piece after compressing the wound to stop bleeding, resulting in the inability to accurately compress the wound to stop bleeding.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example: The present invention provides a technical solution for a rapid hemostasis device for emergency surgery, such as Figure 1-Figure 4 As shown, it includes a shell 1 and a strap 2. The interior of the shell 1 is hollow, and the shell 1 and the strap 2 are connected by a quick-release structure. The purpose is to make it possible to replace different straps 2 according to wounds in different parts of the patient, thereby improving the adaptability of the hemostatic device. Specifically, the shell 1 and the strap 2 are connected by a buckle, and the straps 2 are attached to each other by Velcro, so that the hemostatic device can be fixed to the wound part of the patient.

[0039] The bottom edge of the shell 1 is also designed with a silicone ring 27, which makes the shell 1 softer when in contact with the patient's body, avoiding damage to the patient's healthy tissue. At the same time, during the subsequent compression process of the wound, it can also play a role in sealing between the shell 1 and the body part, preventing bacteria from entering and causing wound infection.

[0040] A horizontally rotatable compression member is provided inside the housing 1. The compression member is designed in an elongated shape, so that it can compress the wound site to stop bleeding more accurately, avoiding long-term compression of healthy tissues that may cause necrosis of healthy tissues. Specifically, the compression member is a compression airbag 3, which compresses and stops bleeding on the wound by supplying air to the compression airbag 3 and expanding it. The compression airbag 3 is mounted on the rotating plate 4, thereby ensuring that the compression airbag 3 applies more uniform pressure to the wound when compressing and stopping bleeding on the patient's wound, avoiding uneven compression force that may result in failure to achieve rapid hemostasis.

[0041] The compression piece is adjusted and rotated by a rotating structure to adapt to wounds with uncertain directions. For example, if a wound appears on the arm at a 45-degree angle to the arm, the compression piece can be rotated by the rotating structure so that the compression piece can be stably fixed on the patient's arm while fitting the direction of the wound.

[0042] In this embodiment, the rotating structure passes through the top of the shell 1 and is detachably connected to the rotating plate 4. The rotating structure is connected to a power supply balloon 6 through a hose 5. The power supply balloon 6 is used to provide a source of compression gas for the compression airbag 3. After the rotating structure is connected to the rotating plate 4, the compression airbag 3 is connected to the power supply balloon 6, and the compression airbag 3 is supplied with air through the power supply balloon 6. A one-way valve is installed on the power supply balloon 6. At the same time, a one-way valve is also installed between the power supply balloon 6 and the hose 5, so that when the power supply balloon 6 is manually squeezed to supply air to the compression airbag 3, gas leakage can be avoided to reduce the compression speed, thereby achieving the effect of rapid hemostasis.

[0043] During use, medical staff first use the appropriate strap 2 with a quick-release structure according to the location of the patient's wound, and then adjust the direction of the compression piece through the rotating structure according to the direction of the patient's wound to adapt to the direction of the wound. Then use the strap 2 to tie the hemostatic device to the location of the patient's wound, and supply air to the compression airbag 3 by pinching the air supply balloon 6 by hand, so that the compression airbag 3 expands and compresses the wound to stop bleeding.

[0044] like Figure 5-Figure 8 As shown, a mounting seat 7 is provided on the top of the housing 1, and a hole 8 penetrating the housing 1 is provided at the bottom of the mounting seat 7;

[0045] The rotating shaft 9 of the rotating structure passes vertically through the housing 1 through the hole 8 and is connected to the compression member through a thread, so that the rotating structure and the compression member can be easily disassembled. When the compression member is used for too long or is seriously contaminated, the compression member can be replaced, avoiding the waste caused by replacing the entire hemostatic device. A sealing plate 10 is provided at the top of the rotating shaft 9, and a rotating knob 11 is installed on the sealing plate 10. The rotation of the rotating knob 11 is used to achieve rotation adjustment of the compression member.

[0046] The rotating shaft 9, the sealing plate 10 and the rotating knob 11 are connected through the middle to form an air flow hole 12, and the air flow hole 12 is connected to the hose 5, so that when the supply air bag 6 is manually squeezed, the gas can be squeezed into the compression air bag 3.

[0047] Specifically, the hose 5 is installed on the top of the rotating knob 11. The purpose is to prevent the connection between the hose 5 and the compression airbag 3 from being interrupted when the rotating knob 11 is rotated, so that no matter how the rotating structure rotates, it will not affect the normal air supply of the air supply balloon 6 to the compression airbag 3.

[0048] The compression airbag 3 is also equipped with an air release valve. When the hemostatic device is used, the gas inside the compression airbag 3 can be released through the air release valve, which is convenient for next use. Specifically, the air release valve can be installed on the rotating knob 11 and connected to the compression airbag 3. Therefore, this installation method will not affect the normal use of the hemostatic device, and at the same time, it can also quickly release air.

[0049] A connecting seat 13 is provided on the top of the rotating plate 4. A threaded hole 14 is provided in the middle of the connecting seat 13. The rotating shaft 9 and the connecting seat 13 are detachably connected by threads. A rotating ring 15 is provided on the periphery of the threaded hole 14. A plurality of equally spaced limiting holes 16 are provided at the bottom of the rotating ring 15.

[0050] The bottom edge of the hole 8 is provided with a plurality of plug-in connectors 17 that match the limiting holes 16, and the plug-in connectors 17 are fixedly mounted on the housing 1;

[0051] When the position of the adjusted compression member needs to be fixed, the knob 11 can be lifted and rotated so that the sealing plate 10 is located at the top of the mounting seat 7. At this time, the connector 17 is inserted into the limiting hole 16 to fix the position of the compression member, thereby preventing the compression member from sliding during compression and hemostasis, thereby preventing the hemostasis effect from being achieved.

[0052] When the position of the pressure piece needs to be adjusted, the sealing plate 10 is pressed downward so that the sealing plate 10 moves downward inside the mounting seat 7. The pressure piece moves downward under the action of the rotating shaft 9, and the connector 17 is separated from the limiting hole 16. At this time, the position of the pressure piece can be adjusted by rotating the knob 11.

[0053] Specifically, a number of silicone sealing rings 18 are vertically arranged and embedded in the inner wall of the mounting seat 7. The distance between two adjacent silicone sealing rings 18 is at least greater than the thickness of the sealing plate 10. The purpose is to ensure that the sealing plate 10 has a certain resistance and limiting ability when moving up and down inside the mounting seat 7, so as to ensure greater stability when adjusting the compression piece. At the same time, the design of the silicone sealing ring 18 can also seal the inside of the mounting seat 7 to prevent the patient's blood or other substances from entering the inside of the mounting seat 7 and causing bacterial growth.

[0054] Specifically, such as Figure 9 As shown, the cross section of the housing 1 is in the positive direction, and extrusion airbags 19 are provided on all four sides of the inner side wall of the housing 1. The length of the compression member is less than the inner side length of the housing 1 and is greater than the minimum distance between two non-adjacent extrusion airbags 19. When the compression member is rotated by the rotary structure to achieve position adjustment, the extrusion airbags 19 can be squeezed to a certain extent, thereby generating gas;

[0055] A liquid storage chamber 21 is provided at the top of the shell 1, and an injection port 22 is provided for injecting medical alcohol into the liquid storage chamber 21. The liquid storage chamber 21 is connected to the extrusion airbag 19, and a one-way valve is installed so that the medical alcohol can only flow from the liquid storage chamber 21 to the extrusion airbag 19.

[0056] Atomizing nozzles 20 are provided at the four corners of the inner side wall of the housing 1. The atomizing nozzles 20 are connected to the extrusion airbag 19 and a one-way valve is installed between the atomizing nozzles 20 so that the medium can only flow from the extrusion airbag 19 to the atomizing nozzles 20.

[0057] The present invention designs the cross section of the shell 1 to be square so that when the compression member is adjusted, the extrusion airbag 19 can be squeezed. At the same time, there is an installation position for the atomizing nozzle 20 that is not affected by the compression member, thereby preventing the rotation of the compression member from being affected by the atomizing nozzle 20 and being unable to be used normally.

[0058] When the extrusion airbag 19 is squeezed, the gas generated will drive the medical alcohol inside the extrusion airbag 19 to flow to the atomizing nozzle 20. Under the action of the gas pressure, the atomizing nozzle 20 sprays the medical alcohol, thereby achieving sterilization and disinfection of the compression member.

[0059] Specifically, a ball 26 is embedded in the side wall of the compression member, so that the friction between the compression member and the extrusion airbag 19 can be reduced, making the compression member easier to rotate.

[0060] Through the above technical solution, it can be found that when the compression piece is set as an adjustable structure, the present application not only considers achieving precise compression and hemostasis of wounds in different directions, but also the rotatable and adjustable compression piece can be used as a power source to sterilize and disinfect the compression piece itself. Moreover, the sterilization and disinfection is carried out before the entire hemostasis device is officially used, which is safer and more hygienic, killing two birds with one stone.

[0061] Specifically, such as Figure 10 As shown, the liquid injection port 22 is sealed by a one-way silicone plug 23, and an air vent 24 is opened in the middle of the one-way silicone plug 23. A silicone valve flap 25 is arranged inside the air vent 24. The silicone valve flap 25 has an initial stress of mutual adhesion. The silicone valve flap 25 is installed toward the liquid storage chamber 21. In this way, when the pressure inside the liquid storage chamber 21 decreases, the external gas can break through the mutually adhered silicone valve flaps 25 and enter the liquid storage chamber 21, thereby achieving a balance between the internal and external pressures.

[0062] The detailed specific sterilization process is: when the extrusion airbag 19 is squeezed, the medical alcohol inside the extrusion airbag 19 will flow to the atomizing nozzle 20. When the pressure of the extrusion airbag 19 is released, the extrusion airbag 19 will return to its original state due to its own recovery ability. At this time, the process of returning to its original state will absorb medical alcohol from the liquid storage chamber 21 for next use. At the same time, the medical alcohol in the liquid storage chamber 21 is absorbed by the extrusion airbag 19, and the pressure will decrease. In order to ensure that the medical alcohol can smoothly enter the extrusion airbag 19, at this time, the silicone valve flap 25 of the one-way silicone plug 23 will automatically open, connecting the liquid storage chamber 21 with the outside air to ensure pressure balance.

[0063] It will be apparent 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 invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
