Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically, to an intelligent pressing hemostasis device after arterial puncture. Background Art

[0002] For critically ill patients, treatment needs to be adjusted through blood gas analysis, and arterial blood needs to be drawn for blood gas analysis, usually from the radial artery of the patient. Since critically ill patients are in a coma state, weak and unconscious all over, and have relatively weak constitutions, medical staff need to press the puncture site at the radial artery with an appropriate force for about 20 - 30 minutes to ensure hemostasis at the puncture site of the radial artery.

[0003] For example, the patent with the publication number CN214907541U discloses a pressing hemostasis device for the radial artery puncture site, including an upper splint and a lower splint. A round rod is provided between one end of the upper splint and one end of the lower splint, and the upper splint and the lower splint are movably connected through the round rod. A torsion spring is provided on one side of the round rod, and the top and bottom of the torsion spring are respectively fixedly connected to the upper splint and the lower splint. By providing a rotating rod and a clamping plate, compared with the prior art, since the rotating rod is threadedly connected to the fixed block through a thread, the pressing plate at the bottom moves downward or upward to adjust the force of the pressing plate, and then the clamping plate is combined with the upper splint, so that the sleeve moves upward through the threaded rod to adjust the pressing force again. However, after the radial artery puncture, the existing pressing hemostasis devices are all controlled by manual pressing, and the manual control of the pressure cannot be accurately controlled to meet the wound healing requirements, affecting the wound healing effect of the patient.

On the circuit main board, a single chip microcomputer for controlling the automatic operation of the device is provided. The single chip microcomputer is electrically connected to a pressure recording module, a display module and a blood pressure recording module;

[0041] The pressure recording module is used to electrically connect to the pressure sensor and then record in real time the magnitude of the pressing force when pressing and hemostatizing the puncture wound of the patient's radial artery, and upload it to the single chip microcomputer for uploading and storage;

[0046] The voice broadcast module is used for voice broadcast when adjusting the pressing force of the detection pressing plate 66 pressing the patient's puncture wound, and emits a voice broadcast after the timed pressing time expires to remind the user that the pressing is over.

[0047] The pressing and hemostasis arm 63 includes a U-shaped frame 631 fixedly connected to the lower end of the top plate of the isolation cover 5 at uniform intervals and a deflection rod 632 movably connected between the inner walls at the bottom of the U-shaped frame 631. A cross-shaped through groove 633 is formed in the deflection rod 632. An L-shaped limiting rod 634 is movably engaged in the cross-shaped through groove 633. A limiting disk 635 is fixedly connected to the outer wall of the vertical rod of the L-shaped limiting rod 634. A return spring 636 is fixedly connected between the top end of the limiting disk 635 and the lower end of the top plate of the isolation cover 5. The top end of the L-shaped limiting rod 634 penetrates through the isolation cover 5 and the end cross bar of the L-shaped limiting rod 634 is movably engaged in the lifting groove 62. A flexible card sleeve 637 is fixedly connected to the end of the deflection rod 632. A disinfected cotton ball 638 is clamped between the inner walls at the end of the flexible card sleeve 637. Convex teeth are evenly distributed in a ring on the inner wall at the port of the flexible card sleeve 637. The convex teeth are made of rubber. The end of the disinfected cotton ball 638 clamped in the port of the flexible card sleeve 637 is puncture-limited by the horizontally arranged convex teeth, so that the other end of the disinfected cotton ball 638 is suspended outside the port of the flexible card sleeve 637. A detection patch 639 is fixedly connected to the bottom of the end of the deflection rod 632 adjacent to the flexible card sleeve 637. The detection patch 639 is electrically connected to the intelligent control box 1.

[0048] The lifting groove 62 is arranged in a ring on the side wall of the adjusting cylinder 6, and one end of the lifting groove 62 sinks in a V-shaped structure. When the L-shaped limiting rod 634 is located in the lifting groove 62 outside the V-shaped structure, the end of the deflection rod 632 is suspended upward below the through hole at the top of the isolation cover 5. At this time, the return spring 636 maintains a normal diastolic state. When the top end of the L-shaped limiting rod 634 is located at the bottom tip of the V-shaped structure of the lifting groove 62, the L-shaped limiting rod 634 is horizontally suspended at the bottom port of the isolation cover 5. At this time, the bottom surface of the L-shaped limiting rod 634 is flush with the bottom port of the isolation cover 5, and the disinfected cotton ball 638 is located at the center of the bottom port of the isolation cover 5.

[0049] Specifically, the auxiliary strap 31 is used to bind the patient's wrist to fix the device, so that the bottom of the isolation cover 5 fits the patient's wrist skin, and then the isolation cover 5 is wrapped around the outside of the puncture wound on the patient's wrist. After the puncture blood collection is completed, the intelligent control box 1 is started. The intelligent control box 1 uses a single-chip microcomputer to independently control the micro-motor to drive the driving gear to mesh with the first toothed ring 61, thereby driving the adjusting cylinder 6 to rotate, and then controlling the V-shaped structure of the lifting groove 62 on the adjusting cylinder 6 to selectively rotate and move to one of the pressing hemostasis arms 63 outside the adjusting cylinder 6. At this time, the top cross bar of the L-shaped limiting rod 634 slides along the V-shaped structure of the lifting groove 62. During the sliding process towards the tip of the V-shaped structure of the lifting groove 62, the V-shaped structure of the lifting groove 62 pushes the vertical rod of the L-shaped limiting rod 634 downward to push the limiting disc 635 to stretch the return spring 636. At the same time, the vertical rod of the L-shaped limiting rod 634 pushes the end of the deflecting rod 632 to deflect downward based on the U-shaped frame 631, so that the disinfected cotton ball 638 fixed at its end fits the patient's wrist skin through the flexible card sleeve 637, so as to automatically cover and press the puncture wound on the patient's wrist, absorb and clean the blood oozing from the puncture wound with the disinfected cotton ball 638 and complete disinfection to prevent wound infection. At the same time, the intelligent control box 1 uses the single-chip microcomputer to control the hydraulic rod 65 to extend to push the detection pressing plate 66 to assist in pressing the disinfected cotton ball 638 covering the puncture wound, so that the disinfected cotton ball 638 closely adheres to the patient's puncture wound, further compresses the puncture wound to stop bleeding for healing. At this time, the detection patch 639 at the bottom of the end of the deflecting rod 632 fits the patient's wrist to monitor the blood pressure. The pressure sensor at the bottom of the detection pressing plate 66 real-time detects the magnitude of the pressing force, and the detection data is transmitted to the single-chip microcomputer of the intelligent control box 1 in real time. The single-chip microcomputer adjusts the extension amount of the hydraulic rod 65 according to the detected blood pressure of the patient, so as to automatically adjust and control the pressing force of the detection pressing plate 66 on the disinfected cotton ball 638, thereby realizing the intelligent automation adjustment of the pressing force on the patient's puncture wound, ensuring that the blood at the patient's puncture wound no longer overflows due to blood pressure and avoiding excessive pressing force from affecting the healing effect of the wound, solving the problems of manual pressing by medical staff and shortage of medical staff, and being convenient to use.

The electric lifting rod 524 adjusts the lower shell 521 slightly based on the mounting strip 522 by lifting and lowering, thereby controlling the needle of the blood collection needle 53 to slightly tilt and point to the center of the bottom port of the isolation cover 5, so as to align it with the radial artery of the patient's wrist.

[0053] Specifically, the medical staff puts on the device for the patient and makes the red laser emitted by the laser lamp 54 point to the radial artery of the patient's wrist, that is, the center of the bottom port of the isolation cover 5 is aligned with the radial artery of the patient's wrist. At this time, the intelligent control box 1 retracts through the electric lifting rod 524, so as to drive the lower housing 521 to deflect slightly based on the mounting strip 522, making the needle of the blood collection needle 53 clamped and fixed between the lower housing 521 and the upper housing 523 tilt slightly and point to the center of the bottom port of the isolation cover 5, that is, aligned with the radial artery of the patient's wrist. At this time, the intelligent control box 1 controls the electric push rod 527 on the inner wall of the card slot 525 on the upper housing 523 to extend. After the electric push rod 527 extends, it pushes the U-shaped clamping plate 526 to slide in the card slot 525 on the upper housing 523, and then pushes the blood collection needle 53 clamped and fixed between the lower housing 521 and the upper housing 523 to slide along the card slot 525, so as to push the blood collection needle 53 to slide along the card slot 525 in the slightly tilted lower housing 521 and then obliquely pierce into the radial artery of the patient's wrist, so that the blood in the radial artery of the patient's wrist is imported into an external sample tube through the blood collection needle 53 along the blood transfusion tube 531 for storage, automatically completing the automatic blood collection of the patient's radial artery. On the contrary, after blood collection, the electric push rod 527 retracts to drive the blood collection needle 53 to automatically withdraw from the radial artery of the patient's wrist, which is convenient to use.

[0054] In order to enhance the healing effect of the puncture wound after the patient's puncture blood collection, as Figures 1-2 , Figure 6 and Figures 8-9 shown, the present embodiment provides the following preferred technical solutions:

[0055] The auxiliary strap 31 includes a communication pipe 311 respectively movably clamped on the bottom plates on both sides of the cold water box 3 and a middle turntable 312 fixedly connected to the bottom of the communication pipe 311. The middle turntable 312 is hollow. The communication pipes 311 are symmetrically arranged about the isolation cylinder 14. The communication pipes 311 movably penetrate through the bottom plate of the cold water box 3 and are provided with raised clamping disks, and the communication pipes 311 are movably clamped on the bottom plate of the cold water box 3 by using the raised clamping disks. At the same time, anti-leakage measures such as sealing rings are arranged between the contact end faces of the bottom plate of the cold water box 3 and the raised clamping disks. A second gear ring 313 is fixedly sleeved on the outer wall of the middle turntable 312. Two sides of the bottom of the middle turntable 312 are respectively fixedly connected with a communicated cold water inlet pipe 314 and a cold water outlet pipe 315. The outer walls of the cold water inlet pipe 314 and the cold water outlet pipe 315 near one end of the middle turntable 312 are movably sleeved with limiting plates 316, and a circulating pipe 317 is fixedly connected at equal intervals between the side walls of the other end joints of the cold water inlet pipe 314 and the cold water outlet pipe 315. A thin gauze sleeve 318 is wrapped and sleeved on the outer wall of the circulating pipe 317.

[0056] The top of the second toothed ring 313 is attached to the bottom of the cold water box 3. An accommodation opening is provided on the side wall of the isolation cylinder 14 corresponding to the second toothed ring 313. One end of the second toothed ring 313 extends into the isolation cylinder 14 through the accommodation opening. A micro motor 15 is fixedly connected to the bottom plate of the intelligent control box 1. The transmission shaft of the micro motor 15 penetrates the bottom plate of the intelligent control box 1 and then extends into the isolation cylinder 14. And a driving gear 16 is fixedly connected to the bottom of the transmission shaft of the micro motor 15. A chain 17 is movably sleeved on the outer wall of the driving gear 16, and the other end of the chain 17 is movably sleeved on the outer wall of the second toothed ring 313.

[0057] A water delivery pipe 32 is fixedly connected to the outer wall of one side of the cold water box 3. The water delivery pipe 32 is externally connected to a cold water circulation pump. There are two water delivery pipes 32, one responsible for water inlet and the other for water outlet to realize the water circulation transportation and update in the cold water box 3. The driving gear 16 is suspended above the top port of the adjusting cylinder 6, and the setting height of the driving gear 16 is the same as the setting height of the second toothed ring 313. The driving gear 16 is located at the midpoint of the connection line between the two second toothed rings 313. The driving gear 16 and the two groups of second toothed rings 313 spread the chain 17 in a triangular shape.

[0058] Specifically, when wearing the device on the patient, put the patient's wrist through the circulation pipes 317 on both sides of the isolation cylinder 14, so that the bottom of the isolation cover 5 fits the patient's wrist skin. At the same time, the limiting plate 316 is suspended on the side of the patient's wrist away from the circulation pipes 317. After calibrating the position of the isolation cover 5 and the patient's wrist radial artery, start the intelligent control box 1 to control the micro motor 15. The micro motor 15 drives the driving gear 16 to rotate. The driving gear 16 drives the second toothed rings 313 suspended outside both ends of the adjusting cylinder 6 to rotate through the chain 17. The second toothed ring 313 drives the middle turntable 312 to rotate at the bottom of the cold water box 3 based on the communicating pipe 311. When the middle turntable 312 rotates, it drives the cold water inlet pipe 314 and the cold water outlet pipe 315 at both ends of the circulation pipe 317 to twist. Since the water stored in the cold water inlet pipe 314 and the cold water outlet pipe 315 will not deform, and with the restriction of the patient's wrist on the limiting plate 316, the cold water inlet pipe 314 and the cold water outlet pipe 315 on the side of the limiting plate 316 close to the middle turntable 312 are twisted. After the two are twisted, they push the limiting plate 316 towards the patient's wrist to contract the cold water inlet pipe 314 and the cold water outlet pipe 315, and at the same time cooperate with the circulation pipe 317 in the gauze sleeve 318 to automatically lock the patient's wrist, so as to realize the automatic wearing and fixing of the device on the patient's wrist. On the contrary, the wearing lock can be released. After the patient's puncture blood collection is completed, the low-temperature water in the cold water box 3 flows through the cold water inlet pipe 314, the circulation pipe 317 and the cold water outlet pipe 315 under the action of the external circulation pump. It passes through the gauze sleeve 318 through the circulation pipe 317 and then performs low-temperature ice compress on the patient's arm on both sides of the puncture wound to reduce the blood flow circulation effect of the patient's wrist, so as to promote the hemostasis and healing effect of the patient's radial artery puncture wound. It is convenient and practical.
