Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a disposable percutaneous coronary intervention hemostat. Background Technology

[0002] Percutaneous coronary intervention (PCI) is a technique used to relieve narrowing or obstruction of the coronary arteries and restore coronary blood flow. After PCI, patients will have wounds on their bodies. At this time, a tourniquet can be used to stop the bleeding at the wound site to help the patient recover.

[0003] However, existing hemostatic devices require several decompressions of the operated limb during pressure hemostasis to avoid ischemic necrosis of distal arterial tissue and skin damage at the compression site. This hemostasis method wastes human resources and time. Furthermore, when using hemostatic devices, doctors need to rely on experience to apply pressure for hemostasis, making it impossible to intuitively understand and apply individualized pressure to the operated limb. This can lead to complications such as excessive swelling and congestion of the operated limb and tension blisters at the pressure site. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the existing technology, which requires the patient's surgical limb to be depressurized several times when applying pressure for hemostasis. This method wastes human resources and time, and doctors rely on experience to apply pressure for hemostasis, making it impossible to intuitively understand and apply individualized pressure to the surgical limb.

[0005] A disposable percutaneous coronary intervention hemostat is proposed, comprising a strap, a locking assembly, a compression device, a balloon, and an inflation assembly. The locking assembly is slidably disposed on the strap, the compression device is located below the locking assembly, and the locking assembly is connected to the compression device. Multiple balloons are disposed inside the compression device and the strap, respectively. The inflation assembly is disposed at one end of the strap and is connected above the strap.

[0006] In this invention, when using a bandage to compress the patient's operated limb, the first and second airbags inside the bandage can be inflated and deflated alternately. This ensures that the wound is always under pressure while relieving the pressure exerted on the limb by the first and second airbags, preventing pressure injuries to the skin at the compression site due to excessive pressure from the first and second airbags. Furthermore, after the bandage is applied to the patient's operated limb, the gas content inside the first and second airbags can be adjusted via the inflation component to further reduce pressure, eliminating the need to untie the bandage. The pressure sensors built into the airbags measure the pressure on the wound when the first, second, and third airbags apply pressure and transmit the values ​​to the doctor. This allows the doctor to intuitively understand the pressure exerted on the patient, eliminating the need for the doctor to rely on experience for pressure-based hemostasis. This addresses the shortcomings of hemostatic devices mentioned in the background, which require multiple decompressions of the operated limb during pressure-based hemostasis, wasting human resources and time, and requiring doctors to rely on experience for pressure-based hemostasis, thus failing to provide intuitive and individualized pressure control for the operated limb.

[0007] In a preferred embodiment of the present invention, the snap-fit ​​assembly includes a fixed plate, a rotating plate, an umbrella-shaped block, and snap teeth. One end of the fixed plate and the rotating plate are hinged together. The strap passes through the middle of the fixed plate and the rotating plate. The pressing device is connected to the fixed plate. The umbrella-shaped block is vertically arranged at the other end of the rotating plate. There are two sets of snap teeth, both of which are arranged on the rotating plate. After the fixed plate and the rotating plate are connected together by the umbrella-shaped block, the snap teeth can be snapped into the gap of the strap, thus restricting the position of the snap-fit ​​assembly and the pressing device.

[0008] In a preferred embodiment of the present invention, the end of the fixing plate is provided with a slot that mates with the umbrella-shaped block. After the umbrella-shaped block is inserted into the slot, the ends of the fixing plate and the rotating plate can be connected together by a snap-fit. The snap-fit ​​disassembly and connection process is simple and quick, and is suitable for occasions where frequent disassembly is required.

[0009] In a preferred embodiment of the present invention, the two ends of the strap are respectively provided with guide rings and Velcro, the Velcro having a good adhesive effect and being reusable.

[0010] In a preferred embodiment of the present invention, the Velcro includes a soft Velcro surface and a barbed Velcro surface, with the barbed Velcro surface positioned close to the center of the strap. After passing the end of the strap with the soft Velcro surface through the center of the guide ring, the soft Velcro surface can be adhered to the barbed Velcro surface, thereby connecting the two ends of the strap.

[0011] In a preferred embodiment of the present invention, the compression device includes an airbag, a pressure sensor, and a waterproof and breathable membrane. The airbag is positioned below the fixed plate, the air bladder is positioned inside the airbag, the pressure sensor is positioned inside the airbag, and the waterproof and breathable membrane is positioned below the airbag and connected to it. When the waterproof and breathable membrane is in close contact with the patient's skin, the wound is located at the square through-hole in the center of the membrane. At this time, the membrane will wrap around the wound and adhere tightly to the patient's skin, thereby preventing blood from the wound from sliding down the patient's skin.

[0012] In a preferred embodiment of the present invention, a foam dressing is provided below the airbag. When the third airbag inflates, it presses the foam dressing onto the patient's wound, thereby preventing wound infection and promoting wound healing.

[0013] In a preferred embodiment of the present invention, the airbag comprises a first airbag, a second airbag, and a third airbag. The first and second airbags are both disposed inside the strap and are connected to an inflation assembly. The third airbag is disposed inside the airbag pouch and is located above the pressure sensor. When gas is inflated into the first and second airbags through the inflation assembly, the inflated first and second airbags will compress the patient's limb inward, thereby applying pressure to the patient's limb. After applying pressure for a period of time, the air inside the first and second airbags can be released through the inflation assembly. At this time, the pressure exerted by the first and second airbags on the patient's limb will decrease, so there is no need to untie the strap.

[0014] In a preferred embodiment of the present invention, the inflation assembly includes a housing, a three-way diverter valve, a ball valve, a first quick connector, and a second quick connector. The housing is located at one end of the strap, the three-way diverter valve is located inside the housing, and there are two ball valves, both located inside the housing. The two ball valves are located at opposite ends of the three-way diverter valve and are respectively connected to the first airbag and the second airbag. The first quick connector is located above the housing and is connected to the three-way diverter valve. The second quick connector is located on one side of the airbag and is connected to the third airbag. When it is necessary to inflate the first and second airbags, the first quick connector can be opened, and then inflated through the first quick connector. Similarly, when needed, opening the first quick connector allows the gas inside the first and second airbags to be released through the first quick connector.

[0015] The advantages of this utility model compared with the prior art are:

[0016] This invention, after binding the patient's limb with a strap, allows for alternating inflation and deflation of the first and second airbags inside the strap via an inflatable component. This ensures that while the patient's wound is constantly under pressure, the pressure on the skin at the corresponding locations of the first and second airbags is relieved, thereby reducing the risk of pressure injury to the patient's skin. When the first, second, and third airbags are used to compress the patient's limb, the pressure sensors built into the airbags measure the pressure value on the wound and transmit the value to the doctor, helping the doctor to intuitively understand the pressure on the patient. When the inflated third airbag presses the foam dressing onto the patient's wound, the waterproof and breathable membrane presses around the wound, preventing blood from flowing down the patient's skin. Furthermore, the breathable material of the waterproof and breathable membrane prevents moisture condensation under the straps from causing skin damage. Attached Figure Description

[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-11 The technical solutions in the embodiments of this utility model will be described in detail below.

[0030] like Figure 1-4 As shown, a disposable percutaneous coronary intervention hemostat includes a strap 1, a locking assembly 2, a compression device 3, a balloon 4, and an inflation assembly 5. The locking assembly 2 is slidably disposed on the strap 1, and the strap 1 passes through the middle of the locking assembly 2, so the relative position of the locking assembly 2 on the strap 1 can be adjusted.

[0031] like Figure 1-4 As shown, the bandage 1 used is a cloth strip, which is made of two layers of cloth strip sewn together. After the bandage 1 is wrapped around the patient's limb, the outer layer of cloth strip that does not contact the patient's skin is not elastic, while the inner layer of cloth strip that is in direct contact with the patient's skin is elastic.

[0032] like Figure 1-4 As shown, after the strap 1 is wrapped around the patient's limb, the outer diameter of the strap 1 will not change, while the inner diameter of the strap 1 can be changed by the action of the airbag 4.

[0033] like Figure 1-4 As shown, guide rings 11 and Velcro 7 are provided at both ends of the strap 1. The guide rings 11 are provided at the ends of the strap 1. The Velcro 7 includes a soft Velcro surface 71 and a barbed Velcro surface 72. Both the soft Velcro surface 71 and the barbed Velcro surface 72 are sewn onto the strap 1.

[0034] like Figure 1-4As shown, both the Velcro soft fuzz surface 71 and the Velcro barbed surface 72 are positioned above the strap 1. The Velcro soft fuzz surface 71 is sewn to the end of the strap 1, and the Velcro barbed surface 72 is located on one side of the Velcro soft fuzz surface 71 and close to the middle of the strap 1.

[0035] like Figure 1-4 As shown, after the end of the strap 1 with the Velcro soft fuzz side 71 passes through the middle of the guide ring 11, the Velcro soft fuzz side 71 can be glued to the Velcro barbed side 72, thereby connecting the two ends of the strap 1.

[0036] like Figure 1-4 As shown, the compression device 3 is located below the snap-fit ​​assembly 2. The snap-fit ​​assembly 2 is connected to the compression device 3, so when the snap-fit ​​assembly 2 moves, it will synchronously drive the compression device 3 to move. When the bandage 1 is wrapped around the patient's limb, the compression device 3 will come into contact with the patient's wound.

[0037] like Figure 1-4 As shown, there are multiple sets of airbags 4, which are respectively installed inside the bandage 1 and the compression device 3. Therefore, when the compression device 3 comes into contact with the wound, gas can be injected into the airbags 4 so that the inflated airbags 4 can press against the patient's wound.

[0038] like Figure 1-4 As shown, the inflation component 5 is located at one end of the strap 1 and is connected to one end of the strap 1. The inflation component 5 is connected to the airbag 4 inside the strap 1, so gas can be inflated into the airbag 4 inside the strap 1 through the inflation component 5 when needed.

[0039] like Figure 5 As shown, the snap-fit ​​assembly 2 includes a fixed plate 21, a rotating plate 22, an umbrella-shaped block 23, and a snap-fit ​​tooth 24. The fixed plate 21 and the rotating plate 22 are respectively located above and below the strap 1, and one end of the fixed plate 21 and the rotating plate 22 are hinged together. Therefore, when the fixed plate 21 remains stationary, the rotating plate 22 can rotate through the hinge point.

[0040] like Figure 5 As shown, the pressing device 3 is located below the fixed plate 21 and connected to the fixed plate 21. The umbrella-shaped block 23 is vertically arranged at the other end of the rotating plate 22. The other end of the fixed plate 21 is provided with a slot 6 that cooperates with the umbrella-shaped block 23. Therefore, after the umbrella-shaped block 23 is inserted into the slot 6, the ends of the fixed plate 21 and the rotating plate 22 can be connected together by snap-fit.

[0041] like Figure 5 As shown, there are two sets of locking teeth 24, both of which are vertically arranged below the rotating plate 22, and the two sets of locking teeth 24 are respectively arranged on both sides of the umbrella-shaped block 23. Both sets of locking teeth 24 are glued to the rotating plate 22.

[0042] like Figure 5 As shown, after the rotating plate 22 rotates downward until the umbrella-shaped block 23 is inserted into the slot 6, the two sets of locking teeth 24 will also be inserted into the gap of the strap 1, thereby restricting the position of the locking assembly 2 and the pressing device 3.

[0043] like Figure 6 As shown, the compression device 3 includes an airbag 31, a pressure sensor 32, and a waterproof and breathable membrane 33. The airbag 31 is located below the fixing plate 21 and is adhered to the fixing plate 21. The pressure sensor 32 is located inside the airbag 31 and is connected to the airbag 31.

[0044] like Figure 6 As shown, the airbag 31 used is made of transparent material (such as plastic), so after the airbag 31 is pressed above the patient's wound, medical staff can directly observe the patient's wound through the airbag 31. The airbag 31 is equipped with a third airbag 43.

[0045] like Figure 6 As shown, the third airbag 43 is located above the pressure sensor 32. Therefore, when the third airbag 43 inflates and compresses the wound, the pressure sensor 32 can measure the amount of pressure applied by the third airbag 43 to the patient's wound. The waterproof and breathable membrane 33 is located below the airbag bag 31 and is attached to the airbag bag 31.

[0046] like Figure 6 As shown, after the third airbag 43 inflates, it will apply pressure to the patient's wound. Then, under the action of the third airbag 43, the airbag bag 31 and the waterproof and breathable membrane 33 will adhere tightly to the patient's skin. A square through hole is provided in the center of the waterproof and breathable membrane 33.

[0047] like Figure 6 As shown, when the waterproof and breathable membrane 33 is tightly attached to the patient's skin, the wound will be located at the square through-hole in the center of the waterproof and breathable membrane 33. At this time, the waterproof and breathable membrane 33 will wrap around the wound and stick tightly to the patient's skin, thereby preventing the blood from the wound from sliding down the patient's skin.

[0048] like Figure 6 As shown, a foam dressing 8 is provided below the airbag 31. The foam dressing 8 is located at the square through-hole in the center of the waterproof and breathable membrane 33 and is adhered to the airbag 31. When the third airbag 43 inflates and presses the waterproof and breathable membrane 33 onto the patient's skin, the foam dressing 8 will come into direct contact with the patient's wound, thereby preventing wound infection and promoting wound healing.

[0049] like Figure 7-10As shown, the airbag 4 includes a first airbag 41, a second airbag 42 and a third airbag 43. The first airbag 41 and the second airbag 42 are both disposed inside the strap 1, and the first airbag 41 and the second airbag 42 are arranged alternately inside the strap 1.

[0050] like Figure 7-10 As shown, the first airbag 41 and the second airbag 42 are both attached to the strap 1, and the first airbag 41 and the second airbag 42 are connected to the inflation assembly 5. Therefore, gas can be injected into the first airbag 41 and the second airbag 42 through the inflation assembly 5 when needed.

[0051] like Figure 7-10 As shown, after the bandage 1 is wrapped around the operated limb, gas can be injected into the first airbag 41 and the second airbag 42 through the inflation component 5. The inflated first airbag 41 and the second airbag 42 will squeeze the patient's limb inward, thereby applying pressure to the patient's limb.

[0052] like Figure 7-10 As shown, after the first airbag 41 and the second airbag 42 are subjected to pressure for a period of time, the air inside the first airbag 41 and the second airbag 42 can be released through the inflation component 5. At this time, the pressure exerted by the first airbag 41 and the second airbag 42 on the patient's limb will be reduced, so there is no need to open the strap 1.

[0053] like Figure 11 As shown, the inflation assembly 5 includes a housing 51, a three-way diverter valve 52, a ball valve 53, a first quick connector 54, and a second quick connector 55 (the quick connectors used are existing products, so they will not be described in detail; the old American 1 / 4 NPT external dental connector is preferred). The housing 51 is located at one end of the bandage 1 and is attached to the top of the bandage 1. When the bandage 1 is wrapped around the surgical limb, the housing 51 will be located on the outside of the bandage 1.

[0054] like Figure 11 As shown, the three-way diverter valve 52 is located inside the housing 51 and is fixedly connected to the bottom plate of the housing 51 with screws. There are two ball valves 53, which are respectively located at both ends of the three-way diverter valve 52, and both ball valves 53 are fixedly connected to the bottom plate of the housing 51 with screws.

[0055] like Figure 11 As shown, the two ball valves 53 are connected to the two outlets of the three-way diverter valve 52 through conduits, so after the airflow enters the interior of the three-way diverter valve 52, the three-way diverter valve 52 can control which ball valve 53 the airflow flows into.

[0056] like Figure 11As shown, the two ball valves 53 are connected to the first airbag 41 and the second airbag 42 inside the strap 1 through pipes respectively. Therefore, after the airflow enters the interior of the three-way diverter valve 52, if the first airbag 41 needs to be inflated, the ball valve 53 corresponding to the first airbag 41 can be opened, so that the airflow enters the interior of the first airbag 41 through the opened ball valve 53. At this time, the ball valve 53 corresponding to the second airbag 42 is in the closed state.

[0057] like Figure 11 As shown, similarly, when the second airbag 42 needs to inflate, the ball valve 53 corresponding to the second airbag 42 can be opened, so that the three-way diverter valve 52 can enter the interior of the second airbag 42 through the opened ball valve 53. At this time, the ball valve 53 corresponding to the first airbag 41 is in the closed state.

[0058] like Figure 11 As shown, after the inflated first airbag 41 and second airbag 42 apply pressure to the patient's operated limb for a period of time, the air inside the first airbag 41 can be released through the ball valve 53, while the second airbag 42 is still inflated.

[0059] like Figure 11 As shown, the pressure on the skin at the corresponding position of the first airbag 41 will be reduced at this time, thereby reducing the risk of pressure injury to the skin at the corresponding position of the first airbag 41. After the skin at the corresponding position of the first airbag 41 has been relieved for a period of time, gas can be injected into the interior of the first airbag 41.

[0060] like Figure 11 As shown, the air inside the second airbag 42 is then released, which reduces the pressure on the skin at the location corresponding to the second airbag 42, thereby reducing the risk of pressure injury to the skin at the location corresponding to the second airbag 42.

[0061] like Figure 11 As shown, by alternately inflating and deflating the first airbag 41 and the second airbag 42, the pressure on the skin at the corresponding positions of the first airbag 41 and the second airbag 42 can be relieved while the bandage 1 is always applying pressure to the patient's operated limb.

[0062] like Figure 11 As shown, the first quick connector 54 is located above the housing 51 and is connected to the middle air inlet of the three-way diverter valve 52 through a pipe. Therefore, when it is necessary to inflate the first airbag 41 and the second airbag 42, the first quick connector 54 can be opened.

[0063] like Figure 11As shown, air is then inflated into the first airbag 41 and the second airbag 42 through the first quick connector 54. Similarly, when the first quick connector 54 is opened when needed, the gas inside the first airbag 41 and the second airbag 42 can be released through the first quick connector 54.

[0064] like Figure 11 As shown, the second quick connector 55 is located on one side of the airbag 31 and is connected to the third airbag 43 through a pipe. Therefore, when it is necessary to inflate the third airbag 43, the second quick connector 55 can be opened and then inflated into the third airbag 43 through the second quick connector 55.

[0065] like Figure 11 As shown, similarly, when the second quick connector 55 is opened when needed, the gas inside the third airbag 43 can be released through the first quick connector 54.

[0066] The movement process of this embodiment is as follows: After the compression device 3 is aligned with the wound on the patient's operated limb, the foam dressing 8 is pressed onto the patient's wound, and then the bandage 1 is wrapped around the patient's operated limb. After passing one end of the bandage 1 with the Velcro soft bristle side 71 through the inside of the guide ring 11 and adhering the Velcro soft bristle side 71 to the Velcro barbed side 72.

[0067] Gas is injected into the first airbag 41 and the second airbag 42 through the first quick connector 54. After the first airbag 41 and the second airbag 42 have expanded and pressed against the patient's operated limb, gas is injected into the third airbag 43 inside the airbag bag 31 through the second quick connector 55.

[0068] After the third airbag 43 inflates, it will press the foam dressing 8 onto the patient's wound. At this time, the pressure sensor 32 will measure the pressure on the patient's wound. After the patient's limb is tied with the bandage 1 for a period of time, the air inside the first airbag 41 can be released through the first quick connector 54.

[0069] After the skin at the location corresponding to the first airbag 41 has been relieved of pressure for a period of time, gas can be drawn into the first airbag 41 through the first quick connector 54, and then the gas inside the second airbag 42 can be released to relieve the pressure on the skin at the location corresponding to the second airbag 42, thereby reducing the risk of pressure injury to the patient's skin.

[0070] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
