Description

Technical Field

[0001] The present invention relates to the technical field of radial artery hemostasis devices, and specifically to an adaptive tightening type radial artery compression hemostasis device. Background Art

[0002] Radial artery compression hemostasis is a hemostasis measure taken after blood is drawn from the radial artery of the wrist. Usually, fingers or a compression device are directly pressed on the most obvious position of the radial artery pulse, that is, the position near the bone on the thumb side of the wrist. By blocking the blood flow, the hemostasis purpose is achieved, thus completing the compression hemostasis of the target position, and it is commonly used in occasions where radial artery puncture is required.

[0003] Most of the existing compression hemostasis devices perform compression by directly pressing or by a combination of a strap and an elastic member. The direct pressing method requires manual long-term pressing of the radial artery. For the patient himself, improper operation is likely to cause repeated bleeding. For medical staff, it will lead to unreasonable occupation of medical resources due to the blood vessel healing time. And the pressing method of the combination of the strap and the elastic member is likely to cause a decrease in the pressing force due to the elastic deformation of the combination of the strap and the elastic member, which is not easy to control. Both methods are likely to affect the healing of the patient's blood vessels. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides an adaptive tightening type radial artery compression hemostasis device, which has the advantages of being able to conveniently fix the wrist and stop bleeding of the radial artery at the same time, and solves the problems that the direct pressing method requires manual long-term pressing of the radial artery. For the patient himself, improper operation is likely to cause repeated bleeding. For medical staff, it will lead to unreasonable occupation of medical resources due to the blood vessel healing time. And the pressing method of the combination of the strap and the elastic member is likely to cause a decrease in the pressing force due to the elastic deformation of the combination of the strap and the elastic member, which is not easy to control. Both methods are likely to affect the healing of the patient's blood vessels.

[0006] (2) Technical Solutions

[0007] The technical solution of the present invention to solve the above technical problems is as follows: An adaptive tightening type radial artery compression hemostasis device includes a wrist frame that fits the wrist, a wrist strap, a driving unit, a bidirectional telescopic driving member, and an expansion unit;

[0008] The bidirectional telescopic driving member includes a telescopic frame and a sealing push rod. The telescopic frame is arranged inside the wrist frame and is in an L shape. The sealing push rod is slidably and hermetically arranged inside both ends of the telescopic frame. The two sealing push rods respectively form compression hemostasis and restraint of the wrist strap;

[0009] The wristband is arranged in a ring shape and bypasses the bidirectional telescopic driving member, and the length of the wristband inside the wrist rest is controlled by being pushed by a sealing push rod;

[0010] The driving unit is connected to the corner of the telescopic frame, and the driving unit forms a drive for the sealing push rod through air pressure.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Further, the two sealing push rods are respectively a pressing push rod and a tensioning push rod. The pressing push rod is transparent and a cotton ball groove is arranged at the end.

[0013] Further, the expansion unit includes a visual function frame connected to the outside of the bidirectional telescopic driving member and having the same movement direction as the pressing push rod. A transparent observation window corresponding to the position of the visual function frame and not affecting sealing is arranged inside the expansion unit.

[0014] Further, the expansion unit further includes expansion slots arranged outside the visual function frame. The number of the expansion slots is two, which are respectively a blood recognition slot and a pressing control slot. Signal contacts for information transmission are arranged on the inner side of the expansion slots.

[0015] Further, the expansion unit further includes a semi-transparent reflector arranged inside the visual function frame. The semi-transparent reflector corresponds to the position of the blood recognition slot, and a blood recognition unit is inserted into the blood recognition slot.

[0016] Further, the blood recognition unit is composed of a CCD recognition module, a power supply module and a processing module;

[0017] The CCD recognition module monitors the bleeding state at the cotton ball in real time through the semi-transparent reflector;

[0018] The power supply module stably supplies power to the whole recognition process;

[0019] The processing module controls the driving unit through the signal contacts.

[0020] Further, an LED lighting member is arranged inside the telescopic frame at the connection with the pressing push rod. The LED lighting member is controlled and powered by the blood recognition unit through the signal contacts.

[0021] Further, a wireless control unit is inserted into the pressing control slot. The wireless control unit includes a rewriting module and a wireless signal processing module;

[0022] The rewriting module rewrites the control logic of the blood recognition unit;

[0023] The wireless signal processing module wirelessly transmits the data of the blood recognition unit through wireless communication and receives the rewritten control information and transmits it to the rewriting module.

[0024] The present invention provides an adaptive tightening radial artery compression hemostasis device. By setting a bidirectional telescopic driving member, when performing hemostasis, the wrist strap can be first put on the outside of the wrist, and then the cotton ball is placed at the cotton ball groove of the pressing push rod. At this time, the driving unit is started to inject air into the inside of the telescopic frame, driving the pressing push rod and the tensioning push rod to start moving. During the movement of the tensioning push rod, as it moves, the length of the wrist strap entering the inside of the wrist frame changes, and the length outside can be shortened until the tensioning push rod moves to the point where the wrist strap fits completely with the wrist, then the fixation with the wrist can be completed, and at the same time, under the influence of air pressure, this fixation effect can be maintained.

[0025] While the wrist strap is being fixed, the pressing push rod is simultaneously affected by air pressure and starts to automatically distribute pressure and press on the bleeding site. While the wrist strap is quickly fixed, the pressing force of the pressing push rod rises, realizing the compression hemostasis of the puncture site.

[0026] At the same time, on this basis, through the set expansion unit, the bleeding situation can be directly judged through the visual function frame, so as to know the hemostasis effect achieved by the current pressing force, and in cooperation with the blood recognition unit, it can avoid the patient's inability to judge by himself due to blood dizziness. Through the blood recognition unit, the power of the driving unit can be intelligently regulated to ensure the hemostasis effect.

[0027] In addition, through the set expansion unit cooperating with the wireless control unit, medical staff can directly understand the bleeding situation of the current pressing site through remote viewing, and rewrite the control information of the pressing force according to whether there is bleeding, which is convenient for targeted control of different bleeding situations of different people.

[0028] In summary, this device has the advantages of being able to conveniently fix the wrist and stop the radial artery bleeding at the same time. Brief Description of the Drawings

[0034] Please refer to Figures 1-3 , the present invention provides an adaptive tightening radial artery compression hemostasis device, which includes a wrist rest 1 that fits the wrist, a wrist strap 2, a driving unit 3, a bidirectional telescopic driving member 4 and an expansion unit 5;

[0035] The bidirectional telescopic driving member 4 includes a telescopic frame 41 and a sealing push rod 42. The telescopic frame 41 is arranged inside the wrist rest 1 and is in an L shape. The sealing push rod 42 is slidably and sealedly arranged inside both ends of the telescopic frame 41. The two sealing push rods 42 respectively form compression hemostasis and constrict the wrist strap 2;

[0036] The wrist strap 2 is arranged in a ring shape and bypasses the bidirectional telescopic driving member 4. The length of the wrist strap 2 located inside the wrist rest 1 is controlled by the pushing of the sealing push rod 42;

[0037] The driving unit 3 is connected to the corner of the telescopic frame 41, and the driving unit 3 drives the sealing push rod 42 through air pressure.

[0038] Furthermore, the two sealing push rods 42 are respectively a pressing push rod 421 and a tensioning push rod 422. The pressing push rod 421 is transparent and a cotton ball groove is arranged at the end.

[0039] The transparent pressing push rod 421 is made of medical-grade polycarbonate material. An antibacterial cotton pad is embedded in the cotton ball groove. The bleeding state of the contact area of the cotton ball can be observed in real time through the transparent wall of the push rod. The visualization of the hemostasis process is realized through the design of the transparent push rod. Combined with the integration of the antibacterial cotton pad, the infection risk is reduced and the operation controllability is improved.

[0040] Furthermore, the expansion unit 5 includes a visual function frame 51 that is externally connected to the bidirectional telescopic driving member 4 and has the same movement direction as the pressing push rod 421. A transparent observation window corresponding to the position of the visual function frame 51 and not affecting the sealing is arranged inside the expansion unit 5.

[0041] Through the design of the visual function frame 51, non-contact monitoring of the hemostasis effect is achieved, avoiding frequent adjustment and interfering with the hemostasis process.

[0042] Furthermore, the expansion unit 5 further includes expansion slots disposed outside the visual function frame 51.

[0047] The power supply module stably supplies power to the overall recognition process;

[0048] The processing module controls the driving unit 3 through the signal contacts.

[0049] The CCD recognition module acquires images of the cotton ball area at a set frame rate. The processing module identifies the blood exudation range through an edge detection algorithm. When the exudation area exceeds the set threshold, the driving unit 3 is triggered to increase the pressure of the pressing push rod 421.

[0050] Furthermore, an LED lighting element is provided inside the telescopic frame 41 at the connection with the pressing push rod 421. The LED lighting element is controlled and powered by the blood recognition unit 6 through the signal contacts.

[0051] The LED light source irradiates the cotton ball area, enhancing the brightness so as to increase the recognition ability of the CCD module for blood and cotton fibers. The brightness of the light source is automatically adjusted according to the ambient light intensity.

[0052] Furthermore, a wireless control unit is inserted inside the pressing control slot. The wireless control unit includes a rewriting module and a wireless signal processing module;

[0053] The rewriting module rewrites the control logic of the blood recognition unit 6;

[0054] The wireless signal processing module wirelessly transmits the data of the blood recognition unit 6 through wireless communication and receives the rewritten control information and transfers it to the rewriting module.

[0055] The wireless control unit 7 supports Bluetooth / Wi-Fi dual-mode communication. Medical staff can receive real-time hemostasis data such as pressure values and bleeding areas through a mobile terminal.
