Description

Technical Field

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

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

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

[0004] For example: The Chinese utility model patent (CN219700024U) discloses an "emergency rapid hemostasis device", which specifically discloses: including a hemostasis box, straps are fixedly sutured on both sides of the hemostasis box, an extrusion assembly is arranged inside the hemostasis box, the extrusion assembly includes an adjustment groove, a threaded rod is rotatably connected inside the adjustment groove, a threaded block is sleeved on the threaded rod, both ends of the bottom of the threaded block are fixedly connected with connecting rods, and the bottom ends of the connecting rods are fixedly connected with hemostasis blocks. It can adjust the position of the hemostasis blocks, thereby conveniently controlling the extrusion force of the extrusion blocks on the wound, avoiding the phenomenon of excessive extrusion, and enhancing the comfort of the patient during treatment and the protection of the wound;

[0005] Although the above rapid hemostasis device can achieve rapid hemostasis of the wound and avoid excessive extrusion at the same time, however, due to the uncertain position, direction, and size of the wounds of the injured patients admitted to the emergency surgery, a single hemostasis device cannot fully cope with the above situations, making it impossible to achieve precise compression and hemostasis of the patient's wound. Therefore, there is an urgent need for a rapid hemostasis device that can adjust the hemostasis device according to the wound direction to achieve precise compression of the wound to solve the above 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 purpose, the present invention provides the following technical solution: A rapid hemostasis device for emergency surgery, including a housing and straps, the interior of the housing is hollow-designed, the housing and the straps are connected through a quick-release structure, a compressible member that can rotate horizontally is arranged inside the housing, the compressible member is long-strip-shaped, and the compressible member is adjusted and rotated through a rotating structure to adapt to wounds with uncertain directions.

[0008] Preferably, the pressing member is a pressing airbag, which presses and stops bleeding on the wound by inflating the pressing airbag. The pressing airbag is installed on the rotating plate. The rotating structure passes through the top of the housing and is detachably connected to the rotating plate. A balloon is connected to the rotating structure through a hose. After the rotating structure is connected to the rotating plate, the pressing airbag is communicated with the balloon, and the balloon supplies air to the pressing airbag.

[0009] Preferably, an installation seat is provided at the top of the housing, and a hole penetrating the housing is opened at the bottom of the installation seat;

[0010] The rotating shaft of the rotating structure vertically penetrates the housing through the hole and is threadedly connected to the pressing member. A sealing plate is provided at the top of the rotating shaft, and a rotating knob is installed on the sealing plate. By rotating the rotating knob, the rotation adjustment of the pressing member is realized;

[0011] An air flow through hole is formed by penetrating and conducting the middle parts of the rotating shaft, the sealing plate and the rotating knob, and the air flow through hole is communicated with the hose.

[0012] Preferably, a connecting seat is provided at the top of the rotating plate, a threaded hole is opened in the middle of the connecting seat, and the rotating shaft and the connecting seat are detachably connected by threads. A rotating ring is opened around the threaded hole, and a number of equally spaced limiting holes are opened at the bottom of the rotating ring;

[0013] A number of plugging members matching the limiting holes are provided at the bottom edge of the hole, and the plugging members are fixedly installed on the housing;

[0014] When the sealing plate is at the topmost end of the installation seat, the plugging member is inserted into the limiting hole to fix the position of the pressing member;

[0015] When the sealing plate is pressed down inside the installation seat, the pressing member moves downward under the action of the rotating shaft, and the plugging member is separated from the limiting hole.

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

[0017] Preferably, the cross-section of the housing is square, extrusion airbags are provided on all four sides of the inner side wall of the housing, the length of the pressing member is less than the inner side length of the housing and greater than the minimum distance between two non-adjacent extrusion airbags, atomizing nozzles are provided at all four corners of the inner side wall of the housing, and the atomizing nozzles are communicated with the extrusion airbags and a one-way valve is installed, so that the medium can only flow from the extrusion airbag to the atomizing nozzle.

[0018] Preferably, a liquid storage cavity is formed at the top of the housing, and a liquid injection port for injecting a medium into the liquid storage cavity is provided. The liquid storage cavity is communicated with 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 beneficial effects of the present invention are as follows:

[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 design of the strip-shaped pressing member enables precise compression hemostasis of the wound. At the same time, the design that the pressing member can rotate enables the rapid hemostasis device to adapt to different wound directions. Moreover, through the acting force generated during the rotation of the pressing member, it can be used to atomize and spray medical alcohol to disinfect the pressing member itself, killing two birds with one stone.

[0024] 2. By designing the rotating structure and the pressing member as a detachable structure in the present invention, when the rapid hemostasis device is used for a long time, only the pressing member can be replaced separately, without replacing the entire hemostasis device, which can save more costs.

[0025] 3. In the present invention, through the plug-in member and the limiting hole, the position of the pressing member can be adjusted only after pressing the rotating structure. After the adjustment is completed, the rotating structure can be manually lifted to fix the position of the pressing member, or when the pressing member compresses and stops bleeding the wound, the rotating structure can be automatically lifted to play a role of limiting and fixing, preventing the pressing member from shifting after compressing and stopping bleeding the wound, resulting in the inability to precisely compress and stop bleeding the wound.

Detailed implementation manners

[0037] 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.

[0038] Embodiment: The present invention provides a technical solution for a rapid hemostasis device for emergency surgery, as Figures 1 - 4 shown, including a housing 1 and a strap 2. The interior of the housing 1 is designed to be hollow. The housing 1 and the strap 2 are connected through a quick-release structure, aiming to enable the replacement of different straps 2 according to the wounds in different parts of the patient, improving the adaptability of the hemostasis device. Specifically, the housing 1 and the strap 2 are connected through a buckle, and the straps 2 are attached to each other through Velcro, so that the hemostasis device can be fixed at the wound site of the patient.

[0039] A silica gel ring 27 is also designed at the bottom edge of the housing 1, making the housing 1 softer when contacting the patient's body, avoiding damage to the patient's healthy tissues. At the same time, during the subsequent compression of the wound, it can also play a role in sealing between the housing 1 and the body part, preventing bacteria from entering and causing wound infection.

[0040] A pressing member that can rotate horizontally is arranged inside the housing 1. The pressing member is designed in a long strip shape, enabling more precise compression hemostasis of the wound site and avoiding long-term compression of healthy tissues, which may lead to necrosis of healthy tissues. Specifically, the pressing member is a pressing airbag 3, and the wound is compressed and stopped bleeding by inflating the pressing airbag 3. The pressing airbag 3 is installed on a rotating plate 4, thus ensuring that when the pressing airbag 3 compresses and stops bleeding the patient's wound, the pressure on the wound is more uniform, avoiding uneven compression force and resulting in failure to achieve the effect of rapid hemostasis.

[0041] The pressing member is adjusted and rotated through a rotating structure to adapt to wounds with uncertain directions. For example, when there is a wound at a 45-degree angle to the arm on the arm, at this time, the pressing member can be rotated through the rotating structure so that the pressing member can be stably fixed on the patient's arm while fitting the wound direction.

[0042] In this embodiment, the rotating structure penetrates the top of the housing 1 and is detachably connected to the rotating plate 4. A balloon 6 for supplying air is connected to the rotating structure through a hose 5. The balloon 6 for supplying air is used to provide the source of pressing gas for the pressing airbag 3. After the rotating structure is connected to the rotating plate 4, the pressing airbag 3 is communicated with the balloon 6 for supplying air, and the balloon 6 for supplying air supplies air to the pressing airbag 3. A one-way valve is installed on the balloon 6 for supplying air. At the same time, a one-way valve is also installed between the balloon 6 for supplying air and the hose 5, so that when the balloon 6 for supplying air is manually squeezed to supply air to the pressing airbag 3, gas leakage can be avoided, resulting in a reduction in the pressing speed, and thus the effect of rapid hemostasis can be achieved.

[0043] During use, the medical staff first fastens the appropriate strap 2 according to the location of the patient's wound through the quick-release structure, and then adjusts the direction of the pressing member through the rotating structure according to the direction of the patient's wound to adapt to the wound direction. Then, the hemostasis device is tied to the location of the patient's wound by using the strap 2, and the balloon 6 for supplying air is squeezed by hand to supply air to the pressing airbag 3, causing the pressing airbag 3 to expand and compress and stop bleeding the wound.

[0044] As Figures 5 - 8 shown, an installation seat 7 is arranged at the top of the housing 1, and a hole 8 penetrating the housing 1 is opened at the bottom of the installation seat 7;

[0045] The rotation axis 9 of the rotation structure vertically penetrates through the hole 8 of the housing 1 and is threadedly connected to the pressing member, facilitating the removal of the rotation structure and the pressing member. When the pressing member has been used for a long time or is severely contaminated, the pressing member can be replaced, avoiding waste caused by replacing the entire hemostatic device. A sealing plate 10 is provided at the top of the rotation axis 9, and a rotation knob 11 is installed on the sealing plate 10. The rotation of the pressing member is adjusted by rotating the rotation knob 11;

[0046] The rotation axis 9, the sealing plate 10, and the middle of the rotation knob 11 are penetrated and conducted to form an air flow hole 12, and the air flow hole 12 is communicated with the hose 5, so that when the air supply balloon 6 is manually squeezed, the gas can be squeezed into the pressing balloon 3.

[0047] Specifically, the hose 5 is installed at the top of the rotation knob 11, so that when the rotation knob 11 rotates, the communication between the hose 5 and the pressing balloon 3 will not be interrupted, ensuring that no matter how the rotation structure rotates, it will not affect the normal air supply of the air supply balloon 6 to the pressing balloon 3.

[0048] A deflation valve is also installed on the pressing balloon 3. After the hemostatic device is used up, the gas inside the pressing balloon 3 can be released through the deflation valve, facilitating the next use. Specifically, the deflation valve can be installed on the rotation knob 11 and communicated with the pressing balloon 3. Therefore, this installation method will not affect the normal use of the hemostatic device and can also deflate quickly.

[0049] A connecting seat 13 is provided at the top of the rotating plate 4. A threaded hole 14 is provided in the middle of the connecting seat 13. The rotation axis 9 and the connecting seat 13 are detachably connected by threads. A rotating ring 15 is provided outside the threaded hole 14, and a number of equally spaced limiting holes 16 are provided at the bottom of the rotating ring 15;

[0050] A number of plug connectors 17 that match the limiting holes 16 are provided at the bottom edge of the hole 8, and the plug connectors 17 are fixedly installed on the housing 1;

[0051] When it is necessary to fix the position of the adjusted pressing member, the rotation knob 11 can be lifted, so that the sealing plate 10 is located at the top of the mounting seat 7. At this time, the plug connector 17 is inserted into the limiting hole 16 to fix the position of the pressing member, preventing the pressing member from sliding during compression hemostasis and failing to achieve the hemostatic effect;

[0052] When it is necessary to adjust the position of the pressing member, press down the sealing plate 10 so that the sealing plate 10 moves downward inside the mounting seat 7. The pressing member moves downward under the action of the rotating shaft 9, and the plug-in member 17 is separated from the limiting hole 16. At this time, the position of the pressing member can be adjusted by rotating the knob 11.

[0053] Specifically, a plurality of silicone rubber seals 18 are vertically arranged and embedded in the inner wall of the mounting seat 7. The distance between adjacent two silicone rubber seals 18 is at least greater than the thickness of the sealing plate 10. The purpose is to enable the sealing plate 10 to have a certain resistance and limiting ability when moving up and down inside the mounting seat 7, ensuring more stability when adjusting the pressing member. At the same time, the design of the silicone rubber seal 18 can also play a role in sealing the inside of the mounting seat 7, preventing the patient's blood or other substances from entering the inside of the mounting seat 7 and causing the growth of bacteria.

[0054] Specifically, as Figure 9 shown, the cross-section of the housing 1 is a square. Four sides of the inner side wall of the housing 1 are provided with extrusion air bags 19. The length of the pressing member is less than the inner side length of the housing 1 and greater than the minimum distance between two non-adjacent extrusion air bags 19. When the position of the pressing member is adjusted by rotating through a rotating structure, the extrusion air bags 19 can be extruded to a certain extent, thereby generating gas;

[0055] A liquid storage cavity 21 is opened at the top of the housing 1, and a liquid injection port 22 for injecting medical alcohol into the liquid storage cavity 21 is opened. The liquid storage cavity 21 is communicated with the extrusion air bags 19, and a one-way valve is installed, so that the medical alcohol can only flow from the liquid storage cavity 21 to the extrusion air bags 19.

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

[0057] In the present invention, the cross-section of the housing 1 is designed as a square, aiming to enable the extrusion air bags 19 to be extruded when the pressing member is adjusted. At the same time, there is also an installation position for the atomizing nozzles 20 that is not affected by the pressing member, avoiding the normal use of the pressing member being affected by the atomizing nozzles 20.

[0058] The gas generated after the extrusion air bags 19 are extruded will drive the medical alcohol inside the extrusion air bags 19 to flow to the atomizing nozzles 20. Under the action of the gas pressure, the atomizing nozzles 20 spray the medical alcohol, thereby realizing the sterilization and disinfection of the pressing member.

[0059] Specifically, ball bearings 26 are embedded in the side wall of the pressing member, so as to reduce the friction between the pressing member and the extrusion airbag 19, making it easier for the pressing member to rotate.

[0060] It can be found from the above technical solutions that when the pressing member is set to an adjustable structure in this application, not only is the accurate compression hemostasis of wounds in different directions considered, but also the rotatable and adjustable pressing member can be used as a power source to sterilize the pressing member itself. Moreover, the sterilization 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, as Figure 10 shown, the liquid injection port 22 is sealed by a one-way silica gel plug 23. A ventilation hole 24 is opened in the middle of the one-way silica gel plug 23. A silica gel valve flap 25 is arranged inside the ventilation hole 24. The silica gel valve flap 25 has an initial stress of mutual fitting. The silica gel valve flap 25 is installed facing the liquid storage cavity 21. In this way, when the pressure inside the liquid storage cavity 21 decreases, the outside air can break through the mutually fitting silica gel valve flap 25 and enter the liquid storage cavity 21, thereby achieving the balance of internal and external pressures.

[0062] The detailed specific sterilization process is as follows: when the extrusion airbag 19 is squeezed, the medical alcohol inside the extrusion airbag 19 will flow to the atomizing nozzle 20. When the extrusion of the pressing member on 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, during the process of returning to its original state, medical alcohol will be sucked from the liquid storage cavity 21 for the next use. At the same time, the medical alcohol in the liquid storage cavity 21 is sucked by the extrusion airbag 19, and the pressure will decrease. In order to ensure that the medical alcohol can smoothly enter the inside of the extrusion airbag 19, at this time, the silica gel valve flap 25 of the one-way silica gel plug 23 will automatically open, connecting the liquid storage cavity 21 with the outside air to ensure pressure balance.

[0063] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
