Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a compressor. Background Art

[0002] Femoral artery puncture is a surgical procedure that can be used to perform most interventional surgeries, such as cerebral angiography, cerebral vascular stent implantation, or aneurysm embolization. After femoral artery puncture, the tube needs to be removed to prevent massive bleeding in the femoral artery. A compressor is generally used for routine compression for 6-8 hours. The mechanical pressure of the compressor is mainly used to apply pressure to the femoral artery puncture site to promote hemostasis and healing of the puncture site.

[0003] During use, the existing compressor generally compresses the patient's puncture site in a small area. Long-term compression causes pain and discomfort in the compressed area of ​​the patient, which is often unbearable for the patient. Medical staff need to manually rotate the compressor to move the compressor away from the patient to reduce the pressure on the patient. However, medical staff often cannot control the number of rotations. The compressor may be relaxed, which will affect the compression effect, and the personalized adjustment performance is poor. Therefore, in response to the above problems, we propose a compressor. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a compressor that, when the compression position of the patient needs to be appropriately adjusted, can selectively relax the pressure on the skin in the local compression area by adjusting the local compression area without reducing the pressure on the skin around the puncture site, thereby achieving personalized adjustment without affecting the compression effect.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: a compressor, comprising a fixed ring, a compression assembly is slidably sleeved inside the fixed ring, the compression assembly comprises a plurality of compression units, the plurality of compression units are slidably sleeved between each other, a fixed frame is provided at the upper end of the fixed ring, a pressure rod is threadedly connected to the upper end of the fixed frame, a resistance plate is rotatably connected to the bottom of the pressure rod, a plurality of lifting assemblies are provided on the resistance plate, the plurality of lifting assemblies are the same in number and correspond one to one to the plurality of compression units, and the lifting assemblies are used to lift the compression units.

[0006] The beneficial effects of the utility model are as follows: by setting up a plurality of mutually nested compression units, when the femoral artery puncture point is compressed, the plurality of compression units are compressed together at the puncture point; when the compression point needs to be adjusted, one of the compression units is pulled up by the pulling component, while the other compression units are still compressed at the puncture point; while the compression force on the skin around the puncture site is not reduced, the local compression area is adjusted so that the skin in the local compression area can selectively relax the pressure, thereby achieving personalized adjustment without affecting the compression effect.

[0007] In order to facilitate the adjustment of multiple compression units and realize the adjustment of local compression areas;

[0008] As a further improvement of the above technical solution: the lifting assembly includes a pull rod, a spiral rod and a balance rod, the bottom of the pull rod is connected to the upper end of the compression unit, the bottom of the spiral rod is rotatably connected to the upper end of the compression unit, the upper ends of the pull rod and the spiral rod both penetrate the top of the resistance plate, and the pull rod is slidingly connected to the resistance plate, the spiral rod is threadedly connected to the resistance plate, the upper end of the pull rod is connected to one end of the balance rod, the upper end of the spiral rod penetrates the other end of the balance rod and is rotatably connected to the balance rod.

[0009] The beneficial effect of this improvement is: when the patient feels great pressure and produces discomfort such as pain, the medical staff can rotate the spiral rod with one hand and pull up the balance rod with the other hand. At this time, the compression unit that needs to be pulled up is pulled up so that it does not press on the puncture site, thereby reducing the discomfort of the local skin around the puncture site. By arbitrarily adjusting any lifting component, any compression unit can be lifted at will, so that the skin in the local compression area can selectively relax the pressure.

[0010] To ensure that the fixing ring is flush with the bottom of the compression unit;

[0011] As a further improvement of the above technical solution: when the bottom of the balance bar is in contact with the top of the fixing frame, the bottoms of the plurality of compression units are flush with the bottom of the fixing ring.

[0012] The beneficial effect of this improvement is that when the bottom of the balance bar contacts the top of the fixing frame, it means that the patient's puncture point is compressed. At this time, the bottom of multiple compression units is flush with the bottom of the fixing ring, and the same compression force can be applied to the puncture point together.

[0013] In order to fix the fixing ring;

[0014] As a further improvement of the above technical solution: four rings are symmetrically arranged on the outer wall of the fixing ring, and two adjacent rings are provided with straps, and the other end of the strap passes through the ring symmetrical to it and is fixed by a connecting piece.

[0015] The beneficial effect of this improvement is that when the compressor is needed, the other ends of the two straps are respectively inserted into the symmetrical loops, and then the straps are fixed by the connecting pieces arranged on the straps. Then, the two straps are cross-fixed, making it easier to fix the compressor at the femoral artery puncture point.

[0016] In order to facilitate pulling up the compression unit;

[0017] As a further improvement of the above technical solution: a handle is provided at the upper end of each of the plurality of balancing rods.

[0018] The beneficial effect of this improvement is that when the compression unit is pulled upward, one hand rotates the spiral rod and the other hand holds the handle and pulls it upward, which facilitates the force on the balance rod and makes it easier to pull the compression assembly upward.

[0019] To increase patient comfort;

[0020] As a further improvement of the above technical solution: the bottom of the plurality of compression units and the bottom of the fixing ring are provided with protective pads, and the inner walls and outer walls of two adjacent protective pads are in contact with each other.

[0021] The beneficial effect of this improvement is that the bottom of the compression unit and the bottom of the fixing ring are prevented from directly contacting the patient's skin through the barrier of the protective pad, thereby reducing the patient's discomfort.

[0022] To increase the friction between the strap and the skin;

[0023] As a further improvement of the above technical solution: a plurality of anti-slip strips are provided on the binding strap.

[0024] The beneficial effect of this improvement is that the provision of the anti-slip strip can increase the friction between the bandage and the skin, and when the bandage is fixed at the femoral artery puncture point, it can prevent the bandage from slipping and increase the stability of the bandage.

When the femoral artery puncture point is compressed, the pressure rod 4 is rotated to pressurize the resistance plate 5 and lower it, so that the plurality of compression units 201 are compressed together at the puncture point. When the compression point needs to be adjusted, one of the compression units 201 is pulled up by the lifting component 6. At this time, the other compression units 201 are still compressed at the skin around the puncture point. While not reducing the pressure force on the skin around the puncture site, the local compression area is adjusted so that the skin in the local compression area can selectively relax the pressure, and personalized adjustment is achieved without affecting the compression effect. The lifting component 6 includes a pull rod 601, a spiral rod 602 and a balance rod 603. 03, the bottom of the pull rod 601 is connected to the upper end of the compression unit 201, the bottom of the spiral rod 602 is rotatably connected to the upper end of the compression unit 201, the upper ends of the pull rod 601 and the spiral rod 602 both penetrate the top of the contact plate 5, and the pull rod 601 is slidably connected to the contact plate 5, the spiral rod 602 is threadedly connected to the contact plate 5, the upper end of the pull rod 601 is connected to one end of the balance rod 603, the upper end of the spiral rod 602 penetrates the other end of the balance rod 603 and is rotatably connected to the balance rod 603, when the patient feels greater pressure and produces discomfort such as pain, at this time, the medical staff can rotate the spiral rod 602 with one hand and pull up the balance rod 60 with the other hand 3. At this time, the compression unit 201 that needs to be pulled up is pulled up so that it does not compress the puncture site, thereby reducing the discomfort of the local skin around the puncture site. By adjusting any one of the lifting components 6 at will, any one of the compression units 201 can be lifted at will, so that the skin in the local compression area can selectively relax the pressure; when the bottom of the balance bar 603 is in contact with the top of the fixing frame 3, the bottoms of multiple compression units 201 are flush with the bottom of the fixing ring 1. When the bottom of the balance bar 603 is in contact with the top of the fixing frame 3, it means that the patient's puncture point is compressed. At this time, the bottoms of multiple compression units 201 are flush with the bottom of the fixing ring 1, and the same compressive force can be applied to the puncture point together;Four loops 7 are symmetrically arranged on the outer wall of the fixing ring 1, and two adjacent loops 7 are provided with straps 8, and the other end of the strap 8 passes through the symmetrical loop 7 and is fixed by a connector, wherein the connector may be a Velcro, a snap-on buckle or the like. When the compressor is needed, the other ends of the two straps 8 are respectively inserted into the symmetrical loops 7, and then the straps 8 are fixed by the connector arranged on the straps 8.

[0033] The working principle and use process of the utility model are as follows: when using the device, the compression unit 201 located in the middle presses the puncture point of the patient, and then the puncture catheter is pulled out, and then one end of the two straps 8 is respectively passed through the two symmetrical rings 7, and then fixed to the femoral artery through the connecting piece. At this time, the two straps 8 are cross-fixed to increase stability, and the anti-slip strip 11 is in contact with the skin to prevent the straps 8 from slipping, and then the pressure rod 4 is rotated. At this time, the bottom of the pressure rod 4 contacts the contact plate 5, so that the contact plate 5 moves downward as a whole, and then drives the lifting component 6 and multiple compression units 201 to move downward to pressurize the area around the puncture point. When the pressurized pressure is sufficient, stop rotating the pressure rod 4. After the pressurization time, the patient feels uncomfortable, and the medical staff can stop by not changing the compression pressure. While exerting force, the skin of the local area of ​​the puncture point is relaxed. The medical staff rotates the spiral rod 602 with one hand and pinches the handle 9 with the other hand, and then pulls the balance rod 603 and the pull rod 601 upward. At this time, the screwing up of the spiral rod 602 and the pulling up of the pull rod 601 drive the compression unit 201 to rise. At this time, the local area compressed by the rising compression unit 201 is relaxed, while the compression force of the remaining compression units 201 still exists, and bleeding from the puncture point can still be avoided. Similarly, the remaining local areas are adjusted in the same way, and the overall operation is convenient. Without reducing the compression force on the skin around the puncture site, the local compression area is adjusted so that the skin in the local compression area can selectively relax the pressure, thereby achieving personalized adjustment without affecting the compression effect.
