Description

Technical Field

[0001] The invention belongs to the technical field of medical supplies, and in particular relates to a wristband type compressor after interventional angiography. Background Art

[0002] Interventional cardiology is a medical procedure that is often used to diagnose and treat cardiovascular disease. This procedure uses a special dye to depict the patient's vascular system to help doctors diagnose and treat diseases. The main operation of interventional angiography is puncture. The puncture point can be the radial artery on the wrist or the femoral artery on the leg. After the operation, the puncture site needs to be compressed to stop bleeding. For the radial artery in the wrist, a compressor is needed to compress and stop bleeding after the operation.

[0003] Existing compressors usually include a hard base and a strap for tightening the patient's wrist. The strap is fastened and fixed with fasteners or adhesive tape. A compression component is arranged on the base, and the compression component is pressed on the puncture point where bleeding needs to be stopped. During the compression hemostasis cycle (half an hour to several hours), the pressure on the puncture point needs to be gradually reduced until the bleeding is completely stopped. The above-mentioned hemostatic compressor has the following problems: first, in order to set a suitable initial pressure on the radial artery and the tightening effect on the patient's wrist, medical staff need to repeatedly adjust the fastener or repeatedly stick / tear the adhesive tape for adjustment, which increases the operating burden of medical staff and increases the discomfort of patients; second, the existing compressor cannot maintain the posture of the patient's wrist, which causes the patient's hand to move randomly during the compression hemostasis cycle, resulting in changes in the pressure of the compressor on the radial artery, especially when the wrist is turned over and the compressor is pressed downward, the pressure on the puncture point will increase significantly, which is easy to cause pressure injury; further, during the compression hemostasis process, the blood exuded from the puncture point will remain on the compression component. Since the consumables cannot be replaced, the next use is only to use cotton swabs for cleaning and disinfection, which is easy to cause cross infection. The entire compressor is used as a consumable and is discarded as a whole after a single use, which undoubtedly increases the consumption of materials and increases the economic burden on patients.

[0004] In summary, it is necessary to develop and design a new type of hemostatic compression device to solve the above-mentioned technical problems. Summary of the invention

[0017] The present invention provides a wristband compressor, which is worn on the patient's wrist like a wristband and is used for compression and hemostasis after interventional angiography in the Department of Cardiology. Compared with the existing hemostatic compressor, the compressor in the present invention has a main body composed of a lower elastic frame and an upper elastic frame that are hingedly connected and is kept in a closed state by a locking structure. The patient's wrist is located between the bottom groove of the upper frame and the top groove of the lower frame.

[0018] The wristband compressor of the present invention is composed of a lower elastic frame and an upper elastic frame to form a support frame with a certain structural strength, so that the posture of the patient's wrist can be constrained during the compression hemostasis cycle, so that the puncture point of the patient's wrist is always facing upward and the disturbance change of the puncture point pressure caused by the patient's arm movement can be avoided, which can maintain the stability and controllability of the hemostasis pressure at the puncture point, which is conducive to smoothly achieving the hemostasis effect. On the other hand, the compression component in the present invention is used as a consumable and can be disassembled and replaced with the main body. In this way, after a single use, the consumable can be replaced to meet the requirements of the next use, which can avoid cross infection and the consumption and waste of materials when the whole is used as a consumable. On the other hand, by installing the lower pad on the lower elastic frame and installing the first upper pad and the second upper pad on the upper elastic frame, the comfort of the patient's wrist is improved.

DETAILED DESCRIPTION

[0028] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0029] Embodiment 1

[0030] See also Figure 1 and Figure 2 The wristband type compressor after interventional angiography of the present invention comprises a lower elastic frame 1 and an upper elastic frame 3, one side of the two is hingedly connected, and the other side is provided with a locking structure with an adjustable degree of engagement. A lower frame top groove 1-2 for accommodating the wrist is provided at the top of the lower elastic frame 1, an upper frame inner frame 3-2 is provided inside the upper elastic frame 3, and an upper frame bottom groove 3-3 for accommodating the wrist is provided in the middle of the upper frame inner frame 3-2.

[0031] When in use, the patient's wrist is located between the top groove 1-2 of the lower frame and the bottom groove 3-3 of the upper frame. Figure 2 In the state shown in FIG. 1 , when the upper elastic frame 3 is rotated and the locking structure is used to close, the compressor of the present invention is worn on the patient's wrist like a wristband. As shown in the figure, the lateral dimension of the lower elastic frame 1 is larger than the lateral dimension of the upper elastic frame 3. Figure 1The equilateral triangle in the figure shows the shape of the wristband compressor in the application state. It can be seen that the compressor is wide at the bottom and narrow at the top in the application state, so it has stability. In this way, when the compressor is worn on the patient's wrist, it can provide a certain restraining effect on the patient's wrist, so that the puncture point of the patient's wrist faces upward, and because the lower elastic frame 1 and the upper elastic frame 3 form a support frame, the patient's wrist cannot move at will, which can effectively prevent the hemostatic pressure on the wrist puncture point from being disturbed, ensure that the hemostatic pressure is stable and controllable, and ensure the effect of compression hemostasis.

[0032] In this embodiment, a lower connecting seat 1-1 is provided at the upper right side of the lower elastic frame 1, and an upper connecting seat 3-1 is provided at the lower right side of the upper elastic frame 3. The lower connecting seat 1-1 and the upper connecting seat 3-1 are hingedly connected by a hinge shaft 2. In this way, when the locking structure is unlocked, the upper elastic frame 3 can rotate around the hinge shaft 2 while the lower elastic frame 1 remains stationary. Figure 2 The open state and Figure 1 Switch between closed states in .

[0033] In this embodiment, the locking structure includes a connecting plate 9 with teeth on the outer side arranged at the lower left side of the upper elastic frame 3 and a connecting socket 11 with teeth on the inner wall arranged at the upper left side of the lower elastic frame 1. When locked, the connecting plate 9 is located in the connecting socket 11 and is combined through the teeth. Since the connecting plate 9 itself has a certain elasticity, the teeth on the connecting plate 9 and the teeth in the connecting socket 11 can maintain a good combination state, and the lower elastic frame 1 and the upper elastic frame 3 are kept in the current locked state without arbitrarily changing the state. It can be seen from this that when it is necessary to clamp the patient's wrist to a greater extent, the connecting plate 9 can be made to enter the connecting socket 11 more. On the contrary, when it is necessary to clamp the patient's wrist to a lesser extent or release the locked state, it is only necessary to press the connecting plate 9 to disengage the teeth, so that the connecting plate 9 is more or completely removed from the connecting socket 11.

[0034] In this embodiment, the lower elastic frame 1 is an integral injection molded part, and the upper elastic frame 3 and the connecting plate 9 are integral injection molded parts, all of which are made of medical grade plastic material. The frame structure shown in the figure itself has certain elastic properties, but is not completely rigid. At the same time, the main body is made of medical grade plastic material, which can also improve the lightweight level and avoid causing additional burden to the patient. A lower frame bottom groove 1-3 is provided in the middle of the bottom of the lower elastic frame 1. The purpose of setting the lower frame bottom groove 1-3 is: when the patient is in a lying state and wears the compressor, the patient's arm and the wristband compressor fall on the bed. At this time, the lower frame bottom groove 1-3 can make the compressor more stable (if the bottom is straight, it is easy to shake left and right under the support of foreign objects in the middle and lower part).

[0035] A compression assembly 6 detachably connected to the upper frame inner frame 3-2 is provided in the groove 3-3 at the bottom of the upper frame, a detachable first upper pad 4 and a second upper pad 8 are respectively installed on the upper elastic frame 3 and on both sides of the compression assembly 6, and a detachable lower pad 10 is installed on the lower elastic frame 1. The compression assembly 6 is used to provide compression and hemostasis to the puncture point of the patient's wrist. In the present invention, since the compression assembly 6 is detachable, the compression assembly 6 is designed as a consumable, which is discarded after a single use and replaced with a new one before the next use. Therefore, the cross infection problem caused by improper cleaning and disinfection in the non-consumable form can be avoided. At the same time, since only this part of the consumables needs to be replaced, the material loss and waste of the compressor can be significantly reduced, and the use cost of the compressor can be reduced.

[0036] See also Figure 6 and Figure 7 , we can see that:

[0037] The compression assembly 6 includes a hard substrate 6-1, a flexible pressure pad 6-3 is provided below the hard substrate 6-1, two insertion rods 6-2 are also provided on the side of the hard substrate 6-1 and the main body of the insertion rod 6-2 extends to the top of the hard substrate 6-1, two transversely penetrating holes 3-4 are provided in the middle of the upper frame inner frame 3-2 and the two insertion rods 6-2 of the compression assembly 6 are respectively inserted into the two insertion holes 3-4.

[0038] The hard substrate 6-1 and the insertion rod 6-2 are integrally molded parts, and can be made of the same medical grade plastic material as the lower elastic frame 1 and the upper elastic frame 3. The flexible pressure pad 6-3 is fixed to the lower surface of the hard substrate 6-1 by bonding. The flexible pressure pad 6-3 can be made of medical grade silicone material, and the surface is coated with medical grade non-woven fabric. When the flexible pressure pad 6-3 is directly pressed on the puncture point of the wrist, the medical grade non-woven fabric can absorb the blood exuded from the puncture point.

[0039] The first upper pad 4 and the second upper pad 8 arranged on the upper elastic frame 3 and the lower pad 10 arranged on the lower elastic frame 1 are used to improve the comfort of the patient's wrist. Figure 5 As shown in the figure, the first upper pad 4, the second upper pad 8 and the lower pad 10 are all made of sponge material, a first upper slot 4-1 is provided on the first upper pad 4, a second upper slot 8-1 is provided on the second upper pad 8, and a lower slot 10-1 is provided on the lower pad 10, the first upper pad 4 and the second upper pad 8 are inserted and installed on the upper elastic frame 3 and the upper frame inner frame 3-2 is embedded in the first upper slot 4-1 and the second upper slot 8-1, the lower pad 10 is inserted on the lower elastic frame 1 and the upper frame body of the lower elastic frame 1 is embedded in the lower slot 10-1.

[0040] Therefore, Figure 1 As shown in , the bottoms of the first upper pad 4 and the second upper pad 8 are located in the groove 3-3 at the bottom of the upper frame and are located on both sides of the flexible pressure pad 6-3, respectively, and the top of the lower pad 10 is located in the groove 1-2 at the top of the lower frame. When the compressor clamps the patient's wrist, the bottoms of the first upper pad 4 and the second upper pad 8 and the flexible pressure pad 6-3 contact the upper part of the patient's wrist, and the top of the lower pad 10 contacts the lower part of the patient's wrist, which improves comfort. The first upper pad 4, the second upper pad 8 and the lower pad 10 can be designed as consumables, which can be discarded and replaced after a certain period of use.

[0041] The upper elastic frame 3 is provided with a threaded rod 5 whose lower end is rotatably connected with the middle top of the upper frame inner frame 3-2, and also includes a rotary pressure relief component 7 that drives the threaded rod 5 to rotate so as to gradually reduce the pressure of the compression component 6 on the wrist. When the patient wears the wristband compressor on the wrist at the beginning, a suitable initial pressure is established. During the compression hemostasis cycle, the rotary pressure relief component 7 is used to rotate the threaded rod 5 regularly and multiple times to reduce the pressure of the compression component 6 on the puncture point of the patient's wrist by reducing the top pushing tension of the upper frame inner frame 3-2, until the hemostasis effect is finally achieved.

[0042] In this embodiment, see Figure 3 and Figure 4 A threaded hole is provided at the middle position of the top of the upper elastic frame 3 and the middle part of the threaded rod 5 is located in the threaded hole. An axial hole 3-5 is provided at the center of the top of the upper frame inner frame 3-2. The lower end of the threaded rod 5 has an axial section and the axial section is located in the axial hole 3-5. In this way, when the threaded rod 5 is rotated forward, the threaded rod 5 pushes the middle part of the upper frame inner frame 3-2 downward, the pushing tension increases, and the compression component 6 moves downward accordingly. On the contrary, when the threaded rod 5 is rotated backward, under the action of the elastic force of the upper frame inner frame 3-2 itself, the distance between the middle part of the upper frame inner frame 3-2 and the top frame body of the upper elastic frame 3 decreases, the pushing tension decreases, and the compression component 6 moves upward accordingly.

[0043] Figure 3 A structural diagram of the first embodiment is given in FIG. 1 . In this embodiment, medical personnel manually operate the threaded rod 5 to rotate to achieve timed and multiple decompression effects.

[0044] like Figure 3As shown in , in this embodiment, the rotary pressure relief assembly 7 includes a knob 7-1, a connecting shaft seat 7-2 with a coupling hole is provided at the center of the knob 7-1, the upper end of the threaded rod 5 is plug-connected to the connecting shaft seat 7-2, a pointer is provided on the knob 7-1, and an annular scale is provided on the top of the upper elastic frame 3. When it is necessary to gradually reduce the pressure of the compression assembly 6 on the puncture point, the threaded rod 5 is operated to rotate in the opposite direction by rotating the knob 7-1, and the number of turns of each reverse rotation can be judged by the indication of the pointer and the annular scale. For example, after wearing the wristband compressor, the threaded rod 5 is reversely rotated for two weeks by rotating the knob 7-1 every 15 minutes until the compression hemostasis cycle ends.

[0045] Embodiment 2

[0046] Figure 4 The structure of the second embodiment is shown in FIG. 1 . In this embodiment, a rotary pressure relief assembly 7 with an electric timing drive function is provided to operate the threaded rod 5 to rotate to achieve a timed and multiple pressure relief effect, thereby further reducing the operating burden of medical staff. In this embodiment, except that the structure of the rotary pressure relief assembly 7 is different from that of the first embodiment, the other structures and operating methods are exactly the same as those of the first embodiment, and are not described in detail.

[0047] like Figure 4 As shown in , in this embodiment, the rotary pressure relief assembly 7 includes a housing 7-4, a shaft seat 7-7 is provided at the center of the housing 7-4, a hollow shaft 7-8 is installed in the shaft seat 7-7, and the upper end of the threaded rod 5 is plug-connected with the hollow shaft 7-8. A driven gear 7-12 is provided on the hollow shaft 7-8, and a micro motor 7-6 and a driving gear 7-5 driven by the micro motor are also installed in the housing 7-4, and the driving gear 7-5 is meshed with the driven gear 7-12 for transmission. A control circuit board 7-11 and a battery 7-10 are also installed in the housing 7-4, and an operating button 7-9 and a charging interface are provided on the housing 7-4. The rotary pressure relief assembly 7 is started by operating the button 7-9, and electric energy is replenished through the charging interface.

[0048] The control circuit board 7-11 has a clock module. After the rotary pressure relief component 7 is started by operating the operating button 7-9, the clock module measures the time. When the timing time is reached, the electric rotary pressure relief component 7 is used to drive the threaded rod 5 to rotate in the opposite direction to achieve a gradual decompression effect. For example, after wearing the wristband compressor, the clock module counts every 15 minutes, and the control circuit board 7-11 starts the micro motor 7-6 to rotate the threaded rod 5 through the gear set for two weeks until the compression hemostasis cycle ends.

[0049] In this embodiment, a plurality of threaded mounting holes 3-6 are provided on the top of the upper elastic frame 3, and the housing 7-4 of the rotary pressure relief assembly 7 is fixedly connected to the upper elastic frame 3 by a plurality of connecting screws 7-3 located in the threaded mounting holes 3-6. Therefore, the manual rotary pressure relief assembly 7 and the electric rotary pressure relief assembly 7 can be selected as needed. When the manual rotary pressure relief assembly 7 is required, the electric rotary pressure relief assembly 7 is disassembled, and then the knob 7-1 is installed on the upper end of the threaded rod 5. Otherwise, the knob 7-1 is disassembled, and the electric rotary pressure relief assembly 7 is installed by the connecting screws 7-3.

[0050] Directions:

[0051] In the initial state, the threaded rod 5 should be controlled to rotate forward to push the upper frame inner frame 3-2 and the compression assembly 6, so that the upper frame inner frame 3-2 maintains the pushing tension; then the patient's wrist is placed in the lower elastic frame 1 and the upper elastic frame 3 and the wrist falls into the top groove 1-2 of the lower frame, and then the upper elastic frame 3 is closed and locked with the locking assembly. During this process, the flexible pressure pad 6-3 of the compression assembly 6 should be accurately pressed onto the puncture point of the wrist; the upper elastic frame 3 is slowly pressed downward to allow the connecting plate 9 to enter the connecting jack 11 more, until the flexible pressure pad 6-3 of the compression assembly 6 forms a suitable initial compression strength at the puncture point;

[0052] When the rotary pressure relief component 7 is a manual component, the medical staff will time a certain time interval, go to the scene and reversely rotate the threaded rod 5 through the knob 7-1 to reduce the pressure of the compression component 6, until the compression hemostasis cycle is over and the wristband compressor is removed from the patient's wrist; when the rotary pressure relief component 7 is an electric component, the rotary pressure relief component 7 will time itself, and at a certain time interval, the rotary pressure relief component 7 will reversely rotate the threaded rod 5 to reduce the pressure of the compression component 6, until the compression hemostasis cycle is over and the wristband compressor is removed from the patient's wrist;

[0053] After this use, the compression assembly 6 as a consumable is pulled out to the side, disassembled, and discarded. Before the next use, a new compression assembly 6 is inserted into the upper frame inner frame 3-2.
