Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and in particular to a feedback hemostasis device. Background Art

[0002] Peripheral venipuncture (venipuncture) is an invasive procedure and the most common clinical procedure. Subcutaneous hemorrhage is the most common adverse reaction during venipuncture. With the widespread use of antiplatelet and anticoagulant drugs in recent years, as well as factors such as advanced patient age and prolonged disease duration, the incidence of post-puncture subcutaneous hemorrhage has continued to increase. This not only increases the difficulty of repeat punctures but also causes pain, increases patient resistance to venipuncture, and may even lead to subcutaneous hematomas and large venous thrombi, a significant factor in increasing medical risk. Post-puncture subcutaneous hemorrhage is particularly common in pediatric patients due to poor cognitive function, hyperactivity, and low compliance. This problem has long plagued clinical practice. Most studies have focused on improving the technique and preventing adverse reactions. However, this condition is affected by numerous factors, including technique, pressure, and instrumentation. Although continuous improvements in technical specifications have reduced the incidence of subcutaneous hemorrhage to a certain extent, the effect has been limited.

The present invention has a simple structure, is easy to use, and can simultaneously perform blood glucose testing and hemostasis. It can achieve hemostasis through blood glucose monitoring feedback, thus providing high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0041] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0042] In Example 1, please refer to Figure 1 and Figure 2 A feedback hemostasis device includes: an outer cover 1 and a suction cup 2 connected to the bottom end of the outer cover 1, through which the suction cup 2 adsorbs the surrounding tissue of the bleeding location, the outer wall of the outer cover 1 is provided with a perspective opening, a perspective window 101 is installed inside the perspective opening, and an exhaust device 3 is provided on the outer wall of the outer cover 1 for suctioning the inside of the outer cover 1, so that the suction cup 2 can be adsorbed on the surrounding tissue of the bleeding location.

[0043] Specifically, the exhaust device 3 includes a mounting shell 301 fixed to the outer wall of the outer cover 1, and the side of the mounting shell 301 away from the outer cover 1 is sealed with an air bag 302. Two exhaust components 303 are symmetrically arranged on the upper end of the mounting shell 301. The outer wall of the outer cover 1 is penetrated by an air outlet 102 connected to the inner side of the mounting shell 301, and a first air inlet component 304 is arranged on the inner side of the air outlet 102.

[0044] Furthermore, the exhaust assembly 303 includes a first connecting chamber 3032 that is opened through the upper end of the mounting shell 301, a first piston disc 3031 is mounted on the upper side of the first connecting chamber 3032, a first guide rod 3033 is fixedly connected to the bottom end of the first piston disc 3031, a first cross 3035 is fixedly connected to the lower inner wall of the first connecting chamber 3032, the first guide rod 3033 slides through the inside of the first cross 3035, a first connecting spring 3034 is sleeved on the outer side of the first guide rod 3033, and the two ends of the first connecting spring 3034 are respectively connected to the first piston disc 3031 and the first cross 3035.

[0045] Furthermore, the first air intake assembly 304 includes a second cross 3043 fixedly connected to the inner wall of the air outlet 102, a second guide rod 3044 slides through the center of the second cross 3043, one end of the second guide rod 3044 is fixedly connected to the second piston disk 3041, and a second connecting spring 3042 is sleeved on the outside of the second guide rod 3044, and the two ends of the second connecting spring 3042 are respectively connected to the second piston disk 3041 and the second cross 3043.

[0046] In this embodiment, during actual medical work, the suction cup 2 is placed on the surrounding tissue of the bleeding site. The suction cup 2 can be made of soft silicone material. By repeatedly pressing the airbag 302, the air inside the outer cover 1 is sucked, so that the suction cup 2 can be stably adsorbed on the surrounding tissue of the bleeding site.

[0047] Specifically, when the airbag 302 is pressed, the air between the airbag 302 and the mounting shell 301 pushes the first piston disc 3031 upward, the first guide rod 3033 constrains and guides the movement of the first piston disc 3031, the first connecting spring 3034 is stretched, and the air between the airbag 302 and the mounting shell 301 is discharged through the first communicating cavity 3032. Afterwards, under the action of the first connecting spring 3034, the first piston disc 3031 moves downward and resets to re-block the first communicating cavity 3032, and the airbag 302 automatically expands and resets due to its own elasticity. During this process, the second piston disc 3041 moves outward, so that the air outlet 102 is in a connected state, so that the air inside the outer cover 1 is sucked into the inner side of the airbag 302 through the air outlet 102. This reciprocating process makes the inner side of the outer cover 1 in a negative pressure state, so that the suction cup 2 can stably adhere to the surrounding tissue of the bleeding location.

[0048] In Example 2, please refer to Figure 1 and Figure 2, including all the contents of Example 1. In addition, a mounting sleeve 4 is embedded on one side of the outer cover 1, and a blood glucose meter 5 is detachably slidably mounted inside the mounting sleeve 4. A blood glucose siphon test strip 501 is detachably inserted at the bottom of the blood glucose meter 5 for absorbing blood exuding from the bleeding site, so that blood glucose can be tested through the blood glucose meter 5. A sealing gasket 401 is provided at the bottom of the mounting sleeve 4, and an insertion opening 402 is provided through the bottom of the mounting sleeve 4 for the blood glucose siphon test strip 501 to be inserted. A hemostatic pad 9 is provided on the inside of the outer cover 1, and a guide cylinder 8 is fixedly mounted on the top of the outer cover 1. A driving mechanism 7 is mounted on the guide cylinder 8 for pushing and pulling the hemostatic pad 9, so that the hemostatic pad 9 can be used to press and stop bleeding at the bleeding point. A transmission mechanism 6 is provided on the upper side of the outer cover 1. When the driving mechanism 7 pushes the hemostatic pad 9, the blood glucose meter 5 can be pulled diagonally upwards through the transmission mechanism 6.

[0049] Specifically, the transmission mechanism 6 includes a bracket 603 fixed to the top of the outer cover 1. The bracket 603 is rotatably provided with a first pulley 602 and a second pulley 604 at both ends away from the outer cover 1. A traction rope 601 is provided between the first pulley 602 and the second pulley 604.

[0050] Specifically, the driving mechanism 7 includes a pull-out column 702 and two limit bars 704 symmetrically fixed to the outer wall of the pull-out column 702. The pull-out column 702 and the limit bars 704 slide through the inside of the guide tube 8. The bottom ends of the pull-out column 702 and the limit bars 704 are jointly fixed with a pressure plate 705, and the pressure plate 705 is connected to the hemostatic pad 9.

[0051] Furthermore, the driving mechanism 7 includes a pressing block 701 fixed to the top of the pull-out column 702. A return spring 703 is sheathed outside the pull-out column 702. The two ends of the return spring 703 are respectively fixedly connected to the pressing block 701 and the guide cylinder 8. One end of the traction rope 601 is connected to the top of the blood glucose monitor 5, and the other end of the traction rope 601 is connected to the top of the pressing block 701.

[0052] In the present embodiment, in clinical work, when there is a wound, after placing this device, blood can be collected using the siphon principle to confirm that there is still blood oozing out. Specifically, the oozing blood is siphoned by the blood glucose siphon test paper 501, and the blood glucose tester 5 is used to test the blood glucose of the collected blood. When the blood stops or the blood volume is significantly reduced, it is impossible to siphon blood, and it is difficult to test blood glucose at this time. At this time, the pull-out column 702 can be pressed by the pressing block 701, so that the return spring 703 is compressed, so that the pull-out column 702 is pressed down by the pressure plate 705 to the hemostatic pad 9, so that the hemostatic pad 9 can achieve the purpose of compression hemostasis at the wound with positive pressure. Wherein the hemostatic pad 9 can adopt different dressings according to the patient's coagulation function. Conventionally, dry sterilized cotton containing tincture of iodine is adopted. For special patients with poor coagulation function, a procoagulant dressing can also be used. It should be noted that the pressing block 701, the outer cover 1 and other structures can be attached with soft silica gel to increase the cushioning performance.

[0053] In this embodiment, in order to ensure that the blood glucose siphon test strip 501 does not affect the hemostatic work of the hemostatic pad 9 during the process of the pulling column 702 pressing down the hemostatic pad 9, the pressing block 701 will pull the blood glucose tester 5 through the traction rope 601 while pressing down, so that the blood glucose tester 5 can slide out from the inside of the installation sleeve 4, thereby enabling the blood glucose tester 5 to slowly move the blood glucose siphon test strip 501 diagonally upward, so that the blood glucose siphon test strip 501 is removed from the wound, avoiding interference with the pressing work of the hemostatic pad 9. After use, the blood glucose siphon test strip 501 can be disposed of according to garbage classification.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
