Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a pulse pressure device. Background Technology

[0002] Blood tests are a common diagnostic procedure when visiting a hospital. Before drawing blood, medical staff need to apply a tourniquet to the patient to make the blood vessels full, making it easier to select the puncture site on the skin of the arm.

[0003] Currently, applying tourniquets requires physical contact between medical staff and patients. Although medical staff disinfect their hands each time, no room temperature disinfection method can kill 100% of bacteria and viruses in a short time—such as 1 minute or less. When medical staff's hands come into contact with patients, there is still a possibility of spreading germs between different patients, leading to cross-infection among patients. Utility Model Content

[0004] Based on the above analysis, the present invention aims to provide a compression device to solve the problem of cross-infection caused by physical contact between medical staff and patients when applying compression bandages in the prior art.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] A pulse-pressing device includes a base and a pulse-pressing unit, wherein the pulse-pressing unit is disposed on the base;

[0007] The base includes a seat and a pressure band groove, the pressure band groove being disposed on the seat; one end of the seat can be placed on the operating table of a medical institution to maintain the stability of the pressure device, and the other end of the seat is used to support the patient's arm;

[0008] The pressure pulse unit includes a strap, a fixed seat, a movable pressure plate, and a pressure plate spring. One end of the strap is connected to the seat body, and the other end of the strap is a free end. The fixed seat is fixedly connected to the inner wall of the seat body. The movable pressure plate is rotatably connected to the seat body via a rotating shaft. One end of the pressure plate spring is connected to the movable pressure plate, and the other end of the pressure plate spring is connected to the seat body. The pressure plate spring is used to push the movable pressure plate towards the fixed seat.

[0009] The strap includes an inner side and an outer side. The inner side can be connected to the patient's arm. The strap can be inserted into the compression band groove and form a buckle structure with the outer wall of the seat. Medical staff only need to hold the free end and use the buckle structure to restrain the patient's arm to perform compression. Medical staff cannot have physical contact with the patient and cannot cause the patient to become infected.

[0010] Furthermore, both the fixed base and the movable pressure plate are provided with anti-slip teeth. The anti-slip teeth are used to increase the contact area between the fixed base and the movable pressure plate and the strap, and to increase the friction between the fixed base and the movable pressure plate and the strap.

[0011] Furthermore, the base also includes a lever groove, which is disposed on the base body; the lever groove is an arc-shaped groove, and the arc-shaped groove is concentric with the rotating shaft.

[0012] Furthermore, the pulse pressure unit also includes a lever, which is disposed on the movable pressure plate. The lever can pass through the lever groove, and medical personnel can press the lever on the outside of the seat to rotate the movable pressure plate away from the fixed seat, so that the strap can be detached from the movable pressure plate and the fixed seat.

[0013] Furthermore, the base also includes a guide plate disposed on the base body. The guide plate can be connected to the outer side of the strap and is used to guide the strap so that the free end of the strap passes between the fixed base and the movable pressure plate.

[0014] Furthermore, the guide plate is an arc-shaped plate.

[0015] Furthermore, the pulse compression unit also includes an isolation pad that can be connected to the inner side of the bandage, the isolation pad being used to isolate the bandage from the patient's arm.

[0016] Furthermore, it also includes a spring-loaded unit, which includes a spring-loaded sheet and a pull cord. The spring-loaded sheet is disposed on the base body, one end of the pull cord is connected to the spring-loaded sheet, and the other end of the pull cord is connected to the strap.

[0017] Furthermore, the rebound sheet is an elastic sheet.

[0018] Furthermore, the base also includes a free end hole, which is disposed on the base body; the free end hole is used to allow the free end of the strap to pass through the base.

[0019] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0020] (1) The strap of the pulse pressure device of this utility model can be inserted into the pulse pressure strap groove and form a buckle structure with the outer wall of the seat. Medical staff only need to hold the free end and use the buckle structure to tighten the patient's arm to perform pulse pressure operation. There will be no limb contact with the patient, thus preventing the patient from getting infected.

[0021] (2) After the patient's arm is restrained, the pressure plate spring of this utility model pushes the movable pressure plate towards the fixed seat, so that the movable pressure plate connects with the outer side of the strap. The fixed seat and the movable pressure plate together clamp the strap to prevent the strap from moving towards the patient's arm and causing the pulse compression to fail. If it is necessary to further tighten the patient's arm, the medical staff only need to pull the free end away from the fixed seat to make the strap detach from the fixed seat. At the same time, the pressure plate spring is compressed, and the inner diameter of the buckle structure is reduced. At this time, stop pulling the free end, and the fixed seat and the movable pressure plate together clamp the strap again to prevent the strap from moving towards the patient's arm. The pulse compression operation is simple and quick.

[0022] (3) Before the pulse compression operation, the rebound piece of this utility model can pull the strap with a pull line so that the patient can insert his arm into the buckle structure; the medical staff pulls the strap to tighten the patient's arm, so that the inner diameter of the buckle structure becomes smaller, the pull line moves with the strap and bends the rebound piece in the direction of the strap to store energy for the rebound piece; after the strap is separated from the movable pressure plate and the fixed seat, the rebound piece can rebound and pull the strap with a pull line to make the inner diameter of the buckle structure larger. Without the operation of the medical staff, the buckle structure can be automatically restored to the state before the pulse compression operation, reducing the labor of the medical staff.

[0023] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing this invention. The objectives and other advantages of this invention can be realized and obtained from the details specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0031] A specific embodiment of this utility model is as follows: Figure 1 As shown, a pulse-pressure device is disclosed, including a base 1 and a pulse-pressure unit 2, with the pulse-pressure unit 2 mounted on the base 1. The base 1 is used to connect to an operating table to maintain the stability of the pulse-pressure device. Medical staff can pull the pulse-pressure unit 2 by hand to perform pulse-pressure on the patient without physical contact between the medical staff and the patient, thus preventing infection.

[0032] Preferably, such as Figure 2 As shown, the base 1 includes a seat 11 and a bandage groove 12, with the bandage groove 12 disposed on the seat 11. One end of the seat 11 can be placed on the operating table to maintain the stability of the bandage device, while the other end of the seat 11 is used to support the patient's arm. The bandage groove 12 is used to accommodate the bandage unit 2.

[0033] Preferably, the outer wall of the seat 11 has an arcuate profile to provide support for the patient's arm.

[0034] Preferably, such as Figure 3 As shown, the pulse compression unit 2 includes a strap 21, one end of which is connected to the base 11, and the other end of which is a free end. The strap 21 includes an inner side and an outer side. The inner side can connect to the patient's arm. The strap 21 can be inserted into the pulse compression groove 12 and forms a buckle structure with the outer wall of the base 11. Medical staff only need to hold the free end and use the buckle structure to restrain the patient's arm to perform pulse compression, so there is no limb contact with the patient and no risk of infection.

[0035] The pulse compression unit 2 also includes a fixed base 22, a movable pressure plate 23, and a pressure plate spring 24. The fixed base 22 is fixedly connected to the inner wall of the base body 11. The movable pressure plate 23 is rotatably connected to the base body 11 via a pivot (not shown in the figure). One end of the pressure plate spring 24 is connected to the movable pressure plate 23, and the other end of the pressure plate spring 24 is connected to the base body 11. The pressure plate spring 24 is used to push the movable pressure plate 23 towards the fixed base 22. After the patient's arm is restrained, the inner side of the strap 21 can connect with the fixed base 22. The pressure plate spring 24 pushes the movable pressure plate 23 towards the fixed base 22, so that the movable pressure plate 23 connects with the outer side of the strap 21. The fixed base 22 and the movable pressure plate 23 together clamp the strap 21 to prevent the strap 21 from moving towards the patient's arm and causing pulse compression failure. If it is necessary to further tighten the patient's arm, medical staff only need to pull the free end away from the fixation seat 22 to make the strap 21 detach from the fixation seat 22. At the same time, the pressure plate spring 24 is compressed, and the inner diameter of the buckle structure is reduced. At this time, stop pulling the free end, and the fixation seat 22 and the movable pressure plate 23 will clamp the strap 21 together again to prevent the strap 21 from moving towards the patient's arm.

[0036] Preferably, both the fixed seat 22 and the movable pressure plate 23 are provided with anti-slip teeth. The anti-slip teeth are used to increase the contact area between the fixed seat 22 and the movable pressure plate 23 and the strap 21, respectively, and increase the friction between the fixed seat 22 and the movable pressure plate 23 and the strap 21, respectively, so as to further prevent the strap 21 from moving towards the patient's arm.

[0037] Preferably, such as Figure 2 and Figure 3 As shown, the base 1 also includes a lever groove 13, which is disposed on the base body 11. The lever groove 13 is an arc-shaped groove, concentric with the rotating shaft. The pulse compression unit 2 also includes a lever 25, which is disposed on the movable pressure plate 23. The lever 25 can pass through the lever groove 13, and medical personnel can press the lever 25 on the outside of the base body 11 to rotate the movable pressure plate 23 away from the fixed base 22. The strap 21 can then detach from the movable pressure plate 23 and the fixed base 22, so that the patient's arm is no longer constricted by the buckle structure, thus completing the pulse compression operation.

[0038] Preferably, the base 1 further includes a guide plate 14, which is disposed on the base body 11. The guide plate 14 is an arc-shaped plate that can be connected to the outer side of the strap 21 and is used to guide the strap 21 so that the free end of the strap 21 passes between the fixed base 22 and the movable pressure plate 23, making it easier for participants to plan the direction of the free end and saving operation time.

[0039] Preferably, the base 1 further includes a free end hole 15, which is disposed on the base body 11. The free end hole 15 is used to allow the free end of the strap 21 to pass through the base 1, so that medical staff only need to pull the free end outside the base 1 without touching the patient's arm.

[0040] Preferably, the bandage 21 is a disposable bandage, or a disposable insulating pad can be attached to the inner side of the bandage 21 to prevent the bandage 21 from coming into contact with the patient's arm and causing infection.

[0041] Preferably, such as Figure 1 As shown, the pulse pressure device in this embodiment also includes a rebound unit 3. The rebound unit 3 includes a rebound sheet 31 and a pull wire 32. The rebound sheet 31 is disposed on the base 11, one end of the pull wire 32 is connected to the rebound sheet 31, and the other end of the pull wire 32 is connected to the outer side of the strap 21. The rebound sheet 31 is an elastic sheet. Before the pulse compression procedure, the rebound spring 31 can pull the strap 21 through the pull line 32, allowing the patient to insert their arm into the buckle structure. When the medical staff pulls the strap 21 to tighten the patient's arm, the inner diameter of the buckle structure decreases. The pull line 32 moves with the strap 21 and bends the rebound spring 31 towards the strap 21, storing energy in the rebound spring 31. After the strap 21 is separated from the movable pressure plate 23 and the fixing seat 22, the rebound spring 31 can rebound and pull the strap 21 through the pull line 32, increasing the inner diameter of the buckle structure. Without the need for medical staff to operate, the buckle structure can automatically return to the state before the pulse compression procedure, reducing the workload of medical staff.

[0042] Compared with the prior art, the strap 21 of the pulse compression device provided in this embodiment can be inserted into the pulse compression strap groove 12 and form a buckle structure with the outer wall of the seat 11. Medical staff only need to pull the free end and use the buckle structure to restrain the patient's arm to perform pulse compression without limb contact with the patient, thus preventing infection. After restraining the patient's arm, the inner side of the strap 21 can be connected to the fixed seat 22. The pressure plate spring 24 pushes the movable pressure plate 23 towards the fixed seat 22, so that the movable pressure plate 23 connects with the outer side of the strap 21. The fixed seat 22 and the movable pressure plate 23 together clamp the strap 21 to prevent the strap 21 from moving towards the patient's arm and causing pulse compression failure. If it is necessary to further tighten the patient's arm, the medical staff only need to pull the free end away from the fixed seat 22 to detach the strap 21 from the fixed seat 22. 2. Simultaneously, the pressure plate spring 24 is compressed, reducing the inner diameter of the buckle structure. At this point, the pulling of the free end stops, and the fixed seat 22 and the movable pressure plate 23 clamp the strap 21 again to prevent the strap 21 from moving towards the patient's arm. Before the pulse compression operation, the rebound piece 31 can pull the strap 21 through the pull line 32, allowing the patient to insert their arm into the buckle structure. When the medical staff pulls the strap 21 to tighten the patient's arm, the inner diameter of the buckle structure decreases, and the pull line 32 moves with the strap 21 and bends the rebound piece 31 towards the strap 21 to store energy. After the strap 21 is separated from the movable pressure plate 23 and the fixed seat 22, the rebound piece 31 can rebound and pull the strap 21 through the pull line 32, increasing the inner diameter of the buckle structure. Without the need for medical staff to operate, the buckle structure can automatically return to the state before the pulse compression operation, reducing the workload of medical staff.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
