Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, and more particularly to an inflatable artery compressor. Background Art

[0002] The arterial compression hemostat currently used in clinical practice includes lifting bracket type, inflatable type and rotary type. When installing, the compression position should be aligned with the arterial puncture point, and the compressor should be fixed with a cotton bandage so that the arterial pulsation can be felt without bleeding at the puncture site.

[0003] A search revealed that existing technologies typically use a fixing strap to secure a hemostat to a patient's forearm or leg. For example, Publication No. CN208017532U, titled "Inflatable Arterial Compression Hemostat," utilizes a lower and upper plate buckle structure to secure the hemostat around the patient's forearm or leg. Furthermore, Publication No. CN114376658A, titled "Arterial Compression Tourniquet," utilizes a fixing strap to secure the fixing plate to the arterial hemostasis site.

[0004] However, there are some defects in the method of fixing with a fixing belt. For example, because the fixing belt is wrapped around the forearm or leg and will last for 5-10 minutes, it will inevitably exert a certain circumferential pressure on the forearm or leg. If the pressure is large, it will cause marks on the forearm or leg, or even redness and swelling of the skin, which will reduce the patient's comfort in using the hemostat and thus reduce the patient's experience.

[0005] Furthermore, a search revealed a patent application with publication number CN118161223A, titled "An Inflatable Arterial Compressor." This device features a cotton ball positioned within a recess at the lower end of an airbag. The airbag is inflated to press the cotton ball against the bleeding site. However, because the cotton ball is in direct contact with the airbag, if bleeding is heavy, blood will inevitably seep through the cotton ball and stain the airbag, contaminating it. If the airbag is not disinfected and reused, there is a risk of blood infection. Therefore, this compressor is not very safe.

[0006] Therefore, how to provide an inflatable arterial compressor that improves patient comfort and safety is an urgent problem that those skilled in the art need to solve. Utility Model Content

[0007] In view of this, the utility model provides an inflatable arterial compressor that improves patient comfort and safety in use.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] An inflatable arterial compressor, comprising:

[0010] a base plate on which the arms can be placed;

[0011] A vertical telescopic rod, the lower end of which is mounted on the top of the base plate;

[0012] A transverse support rod, one end of which is fixedly connected to the upper end of the vertical telescopic rod, and a long strip adjustment hole is opened on the top surface of the transverse support rod;

[0013] A compression screw rod, the compression screw rod being passed through the elongated adjustment hole, the compression screw rod being threaded with an upper limit nut and a lower limit nut, the upper limit nut and the lower limit nut being respectively stopped on the top end surface and the bottom end surface of the transverse support rod;

[0014] A compression airbag, wherein the top end of the compression airbag is fixedly connected to the lower end of the compression screw, and the bottom end surface of the compression airbag has a card slot for placing an alcohol cotton ball;

[0015] An inflation and deflation component, wherein the inflation and deflation port of the inflation and deflation component is connected and communicated with the compression airbag.

[0016] It can be seen from the above technical solution that compared with the prior art, the utility model discloses an inflatable arterial compressor. When in use, the patient places his arm on the base plate, and then the medical staff adjusts the height of the vertical telescopic rod to an appropriate position, and then lowers the compression screw, and then adjusts the compression airbag to an appropriate position, so that the alcohol cotton ball on the compression airbag contacts the bleeding point, and locks the upper limit nut and the lower limit nut to fix the position of the compression screw to prevent it from moving. Then, the inflation and deflation component inflates the compression airbag, and then the inflated compression airbag is used to appropriately press the bleeding point to stop bleeding. When the bleeding point stops bleeding, the inflation and deflation component deflates the gas in the compression airbag for the next use.

[0017] Therefore, the inflatable arterial compressor can achieve inflatable compression hemostasis without the use of a traditional fixation belt, effectively avoiding the phenomenon of bruises, redness and swelling on the arm caused by using a fixation belt to tie the patient's arm. Moreover, the compressor only compresses the hemostasis point and does not need to compress other parts, thereby greatly improving the comfort of the patient in using the hemostat. Moreover, the device is easy to operate and does not require the tedious hemostasis compression steps of early tying and later untying required by the traditional use of a fixation belt, which greatly simplifies the operation of medical staff and improves the convenience and ease of use.

[0018] Furthermore, the vertical telescopic rod includes:

[0019] A support rod, wherein the lower end of the support rod is fixedly or rotatably connected to the top of the base plate, the upper end of the support rod is provided with a plug hole, and the rod wall of the support rod is provided with a first positioning hole penetrating the plug hole;

[0020] A telescopic rod is inserted into the insertion hole, and a plurality of second positioning holes are uniformly arranged on the rod wall of the telescopic rod.

[0021] A positioning pin is inserted into the first positioning hole and the second positioning hole.

[0022] The above technical solution has the beneficial effect that the telescopic rod is adjusted in position up and down by inserting the positioning pin into the corresponding second positioning hole, thereby achieving a wide range of adjustment of the position of the compression air bag up and down.

[0023] Further, an installation groove is arranged at the top end of the bottom plate, and a T-shaped connecting block is fixed to the lower end of the support rod, which is rotatably arranged in the installation groove.

[0024] The above technical solution has the beneficial effect that the transverse support rod can be rotated, thereby achieving swing adjustment of the compression air bag in the horizontal direction, and the compression screw can move left and right in the long strip-shaped adjustment hole, thereby achieving fine adjustment of the left and right positions of the compression air bag, and the compression air bag can be fine adjusted in position up and down by moving the compression screw up and down. Therefore, the position of the compression air bag can be flexibly adjusted, and the compression air bag can be quickly aligned with the bleeding point to achieve compression hemostasis.

[0025] Further, a universal joint is fixed to the lower end of the compression screw, a universal plate is fixed to the universal rod of the universal joint, and the top end of the compression air bag is fixedly connected to the bottom end of the universal plate.

[0026] The above technical solution has the beneficial effect that the universal joint allows the compression air bag to rotate 360°, thereby greatly improving the flexibility of position adjustment of the compression air bag.

[0027] Further, the air charging and discharging assembly comprises:

[0028] An air charging bag is arranged on the bottom plate.

[0029] An air charging pipe is connected and communicated with the air charging port of the air charging bag at one end and connected and communicated with the compression air bag at the other end, and an air charging regulator is arranged on the air charging pipe.

[0030] An air discharging pipe is connected and communicated with the air charging pipe at one end, and an air discharging regulator is arranged on the air discharging pipe.

[0031] The beneficial effects of the above technical solution are as follows: both the inflation regulator and the deflation regulator adopt the existing flow regulator on the infusion tube, which adjusts the flow rate of the infusion tube and switches it on and off by adjusting the position of the roller. Therefore, when inflating, the inflation tube is opened by rotating the roller on the inflation regulator, and the deflation tube is blocked by rotating the roller on the deflation regulator. Then, the inflatable bag is pressed, and the gas in the inflatable bag enters the inflation tube, thereby inflating and expanding the compression bag, thereby achieving the function of pressing the bleeding point with an alcohol cotton ball to stop bleeding. When pressing to stop bleeding, the roller on the inflation regulator can be rotated to block the inflation tube, so that the gas in the compression bag does not flow back into the inflation bag, thereby achieving the pressure-maintaining hemostasis function of the compression bag. When deflation is required, the roller on the deflation regulator is rotated to open the deflation tube, thereby allowing the gas in the compression bag to be discharged through the deflation tube, thereby achieving the exhaust operation of the compression bag.

[0032] Therefore, the compressor uses an inflation regulator and a deflation regulator to adjust the inflation and deflation of the compression airbag. The operation is extremely simple, and the inflation and deflation amounts of the compression airbag can be adjusted by simply turning the rollers on the inflation regulator and the deflation regulator, thereby quickly adjusting the pressure of the compression airbag to an appropriate position.

[0033] Furthermore, a plurality of hanging rings are slidably connected to the bottom end of the transverse support rod, and the inflation tube is passed through the hanging rings.

[0034] The beneficial effects of adopting the above technical solution are: the inflation tube is hung on the transverse support rod to avoid the problem of entanglement of the inflation tube, and the inflation tube is moved left and right on the transverse support rod through a sliding hanging ring, so that when the position of the compression airbag is adjusted, the inflation tube will not pull the compression airbag, thereby ensuring the adjustability of the position of the compression airbag.

[0035] Furthermore, a T-shaped groove is provided on the bottom end surface of the transverse support rod, and a T-shaped slider is provided on the top end of the hanging ring, and the T-shaped slider is slidably installed in the T-shaped groove.

[0036] The beneficial effect of adopting the above technical solution is: the hanging ring can slide left and right along the length direction of the T-shaped groove, thereby realizing the left and right movement of the inflation tube.

[0037] Furthermore, it also includes a disposable isolation layer bonded to the bottom end surface of the compression airbag for isolating the alcohol cotton ball and the compression airbag, and the middle part of the disposable isolation layer can be recessed into the embedding groove.

[0038] The beneficial effects produced by the above technical solutions are that the disposable isolation layer effectively isolates the alcohol cotton ball and the compression air bag, avoids blood on the alcohol cotton ball from sticking to the compression air bag, easily causes the risk of cross infection, and improves the use safety.

[0039] Further, a supporting groove plate for placing an arm is arranged on the bottom plate top end at a position below the compression air bag, and the groove bottom surface of the supporting groove plate has an outer convex surface for supporting a wrist.

[0040] The beneficial effects produced by the above technical solutions are that the patient's wrist can be placed on the outer convex surface, the wrist contact part is convex so as to draw blood, and the hand is also comfortable.

[0041] Further, a soft pad layer is arranged on the outer convex surface.

[0042] The beneficial effects produced by the above technical solutions are that the comfort of the arm placed on the outer convex surface is improved. BRIEF DESCRIPTION OF DRAWINGS
