Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical auxiliary devices, in particular to a hemostasis device for cardiology department. BACKGROUND

[0002] After venous blood sampling, the blood sampling site needs to be pressed for a certain period of time to stop bleeding. Currently, the pressing after blood sampling is usually performed by medical staff pressing a medical cotton swab at the blood sampling site after pulling out the blood sampling needle, and then the patient takes over and presses it by himself. In the actual application process, it is found that some patients apply too little pressure, which leads to continuous bleeding due to insufficient pressure; some patients also apply too much pressure due to their concern about the inability to stop bleeding, which finally leads to blood leakage and subcutaneous congestion around the blood sampling site. Both of these situations will cause pain at the blood sampling site and around the congested area for a long time and require a longer recovery time. Secondly, when the patient takes over the medical staff to press the medical cotton swab, there is also a situation of cotton swab displacement, which also leads to continuous bleeding.

[0003] Most patients in the cardiology department are elderly patients, who often do not press with appropriate force and for a sufficient period of time when pressing by themselves according to the instructions of medical staff. In addition, as the age of patients increases, the number of underlying diseases also increases, and some patients have uncontrollable hand tremors. Therefore, the situation of cotton swab displacement is more common when the patient takes over the medical staff to press. In addition, some elderly patients have reduced coagulation function or reduced coagulation speed due to the use of anticoagulant drugs. When the pressing force is too small and the pressing time is too short, it will lead to obvious bleeding, and obvious bleeding will cause anxiety and fear in elderly patients or reduce their trust in medical staff, which will have an adverse effect on subsequent treatment.

[0004] In order to solve the above-mentioned problem of patient self-pressing hemostasis, there are some hemostasis devices that can press the blood sampling site to stop bleeding at present, such as the "arm infusion port needle withdrawal hemostasis device" disclosed in patent No. CN215018365U, which sets a hemostatic band main body connected by magic tape to form a fastening ring, a sliding block is provided on the hemostatic band main body, a through hole is provided on the sliding block for the hemostatic band main body to pass through, an elastic pressing mechanism is provided on the side wall of the sliding block and the side that contacts the human body, the elastic pressing mechanism includes a pressing plate connected to the side wall of the sliding block by a spring, an arc-shaped groove is provided on the side of the pressing plate that contacts the human body, a positioning mechanism is provided on the sliding block, the positioning mechanism includes a threaded cylinder provided on the outer side of the sliding block and arranged vertically to the through hole, a positioning bolt is screwed into the threaded cylinder and penetrates into the through hole, and a rotating handle is provided on the outer top end of the positioning bolt.

[0005] The hemostatic device is used by sleeving the main body of the hemostatic band on the arm of a patient, aligning the elastic pressing mechanism with the blood sampling position, and then adjusting the pressure between the pressing plate and the patient by rotating the handle to keep the pressure of the blood sampling position within a reasonable range.

[0006] However, when blood sampling is performed, the blood sampling position is not only the arm. When the blood sampling position is the neck side, the head, or the like, or the back of the hand after infusion needs to be pressed, the hemostatic band cannot be sleeved on the neck side, the head, and the palm, so the pressing plate cannot be pressed on the blood sampling position. Secondly, since the contact surface of the pressing plate and the skin of the patient is much larger than the needle hole of the blood sampling position, the pressing plate actually tests the pressure on the area around the blood sampling hole. In order to safely pull out the blood sampling needle, the pressing plate needs to be aligned with the blood sampling hole, the blood sampling needle needs to be pulled out immediately, and then the pressing plate needs to be pressed on the blood sampling position. The operation steps are relatively complex. However, the hospital needs to sample blood from hundreds or even thousands of people every day. Undoubtedly, such operation will slow down the blood sampling speed. Moreover, when the hemostatic band is worn, the pressure of the finger pressing plate cannot be completely controlled. When the pressure increases, the patient will feel pain and there is a risk of blood stasis. When the pressure decreases, there is also a risk of not being able to stop bleeding. SUMMARY

[0007] The present application aims to provide a hemostatic device for cardiology department to solve the problems that the blood sampling device can only press the arm and the operation process is relatively complex.

[0008] To achieve the above-mentioned purpose, the application adopts the following technical scheme: a hemostatic device for cardiology department, comprising a shell, a pressing unit and a fixed wing, the pressing unit comprising a pressing plate, a water-absorbing cotton sheet and a screw rod, the shell is provided with a groove, the pressing plate is located in the groove and the bottom of the pressing plate is lower than the shell, the bottom of the pressing plate is provided with a strip-shaped groove which transversely penetrates the circumferential side wall of the pressing plate, the lower end of the screw rod is fixed with the pressing plate, the upper end penetrates the top of the shell in vertical direction and is threadedly connected with the shell; the water-absorbing cotton sheet is located below the pressing plate, the diameter of the water-absorbing cotton sheet is larger than that of the pressing plate, and the part of the water-absorbing cotton sheet located outside the pressing plate is fixed on the shell; the fixed wing comprises an integrated pressing part and two fixed parts, the pressing part is opposite to the top of the shell, the fixed parts are respectively located on both sides of the shell, and the bottom of the fixed part is provided with adhesive, the length of the fixed part is greater than the length between the bottom of the pressing plate and the top of the shell.

[0009] The beneficial effects of the present application are as follows:

[0010] The fixed wing provided in the scheme can be pasted on the skin of the patient during use, so that a bracelet type tourniquet does not need to be provided, and the use position is no longer limited to the arm. Secondly, the fixed wing is directly pasted on the skin during use, and the operation is simple, and the shell and the water-absorbing cotton sheet can be pressed on the blood collection position by the fixed band. The pressure plate in the scheme directly tests the pressure on the water-absorbing cotton sheet, thereby providing the pressure required for hemostasis. The strip-shaped groove is provided on the pressure plate, and the strip-shaped groove is aligned with the blood collection needle, so that the wearing of the blood collection device is completed when the blood collection needle is not pulled out. At this time, the strip-shaped groove reserves enough space for the blood collection needle, so that the pressure plate does not test the pressure on the blood collection position, and the blood collection and the pulling out of the blood collection needle are not affected. After the blood collection is completed and the blood collection needle is pulled out, the pressure plate can be lowered by rotating the screw rod, thereby providing the pressure for hemostasis. The rotation angle of the screw rod is proportional to the distance that the pressure plate is moved downward by the screw rod, so that the pressure applied by the pressure plate to the blood collection position can be more intuitively controlled by controlling the rotation angle of the screw rod. Therefore, for different patients or different blood collection positions, the applied pressure can be easily adjusted by the rotation angle of the screw rod. Further, the top of the screw rod is fixed with a handle.

[0011] The beneficial effect of the scheme is that the screw rod can be more easily rotated by the handle.

[0012] Further, the handle is long strip-shaped, and the extension direction of the handle is the same as the extension direction of the strip-shaped groove.

[0013] The beneficial effect of the scheme is that the handle in the scheme can assist in determining the position of the strip-shaped groove, thereby facilitating the alignment of the strip-shaped groove with the blood collection needle.

[0014] Further, the top of the shell is provided with two mark lines, and the two mark lines are opposite to the two side walls of the strip-shaped groove, respectively.

[0015] The beneficial effect of the scheme is that the position of the strip-shaped groove can also be directly determined by the mark lines, and compared with the handle, the mark lines are located on the shell and have a larger length, so that the position of the strip-shaped groove can be better determined.

[0016] Further, the shell stores a disinfectant, the top of the water-absorbing cotton sheet is covered with a waterproof layer, the waterproof layer is fixed with the water-absorbing cotton sheet and the shell, and the pressure plate is fixed with a sharp block for piercing the waterproof layer.

[0017] The beneficial effect of the scheme is that in the initial stage of hemostasis, there is still a small amount of bleeding at the blood sampling position, at this time the exuded blood will be sucked into the water-absorbing cotton piece, and due to different coagulation functions, the amount of bleeding of some patients will be relatively more, if the hemostatic device is not removed for a long time, the blood in the water-absorbing cotton piece will coagulate and adhere to the scab at the blood sampling hole, at this time, directly pulling the water-absorbing cotton piece will cause the scab at the blood sampling hole to fall off. After the waterproof layer in the scheme breaks, the disinfectant seeps into the water-absorbing cotton piece to soften the adhesion position, avoid pulling the scab, and also disinfect the skin around the blood sampling hole to reduce the risk of infection.

[0018] Further, the end of the sharp block away from the pressing plate is a sharp end, and the sharp end is curved to the side away from the rotating direction of the pressing plate, and the side wall of the sharp block towards the rotating direction of the pressing plate is an arc surface.

[0019] The beneficial effect of the scheme is that when the pressing plate is positively rotated to increase the pressure on the skin, the arc surface will not damage the waterproof layer, and when the hemostatic device needs to be removed, the pressing plate is reversely rotated to pierce the waterproof layer, avoiding the disinfectant from seeping out too quickly to cause pain at the blood sampling hole.

[0020] Further, a water bag is arranged in the groove, the disinfectant is arranged in the water bag, and the sharp block can pierce the water bag.

[0021] The beneficial effect of the scheme is that the water bag protects the disinfectant, further avoiding the disinfectant from being contaminated.

[0022] Further, the strip-shaped groove is communicated with a water guide strip, and the water guide strip extends to the outside of the shell.

[0023] The beneficial effect of the scheme is that under the action of siphon, the disinfectant flows along the water guide strip, and the longer the time, the longer the part of the water guide strip wetted by the disinfectant, so that the disinfectant on the water guide strip can prompt the patient to reach the pressing time, avoiding that the surrounding tissue of the blood sampling hole is damaged due to too long pressing.

[0024] Further, the water guide strip extends to the fixed wing and is fixedly connected with the fixed wing.

[0025] The beneficial effect of the scheme is that the fixed wing can better fix the water guide strip.

[0026] Further, a sealing rubber tube is arranged at the end of the water guide strip away from the strip-shaped groove, a color developing agent is arranged at the end of the sealing rubber tube away from the strip-shaped groove, and the color developing agent is in contact with the water guide strip.

[0027] The beneficial effect of the scheme is that after reaching the pressing time of 3-5 minutes, the disinfectant infiltrates to the color developing agent along the water guide strip, so that the color developing agent displays color, and the change of color can better play a prompting effect.

[0034] EMBODIMENT

[0035] The embodiment is basically as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , a hemostatic device for cardiology department, comprising a shell 1, a pressing unit and a fixed wing 6, the pressing unit comprising a pressure plate 4, a water-absorbing cotton sheet 2 and a screw rod 11, the shell 1 is provided with a recess, the upper part of the pressure plate 4 is located in the recess and the bottom part is lower than the shell 1, the bottom part of the pressure plate 4 is provided with a strip-shaped groove 41, the strip-shaped groove 41 transversely penetrates the circumferential side wall of the pressure plate 4. The screw rod 11 is vertically arranged, the lower end of the screw rod 11 is integrally injection molded with the pressure plate 4, the upper end vertically penetrates the top of the shell 1 and extends above the shell 1, the screw rod 11 is threadedly matched with the shell 1, and the top of the screw rod 11 is glued with a long strip-shaped handle 12, the handle 12 extends along the direction of the strip-shaped groove 41. In actual implementation, two mark lines can also be provided on the top of the shell 1, and the mark lines are opposite to the two side walls of the strip-shaped groove 41, and the end parts of the mark lines can extend to the vertical side wall of the shell 1, thereby assisting medical staff to better align the blood taking needle with the strip-shaped groove 41.

[0036] The water bag 13 is glued in the groove by adhesive, and the water bag 13 stores disinfectant liquid, and the disinfectant liquid in the embodiment is alcohol. The lower part of the water bag 13 extends between the pressing plate 4 and the side wall of the groove. The side wall of the pressing plate 4 is fixed with two sharp blocks 42, and the upper and lower sharp blocks 42 are used to pierce the water bag 13 and the waterproof layer 3 respectively. The sharp block 42 used to pierce the waterproof layer 3 is provided with a sharp end away from the pressing plate 4, and the sharp end is curved away from the water bag 13. The side of the sharp block 42 facing the water bag 13 is an arc surface. The sharp end of the other sharp block 42 is curved in the opposite direction to the previous sharp block 42, so that the pressing plate 4 can pierce the water bag 13 when it is adjusted downward.

[0037] The water-absorbing cotton sheet 2 is located below the pressing plate 4, and the diameter of the water-absorbing cotton sheet 2 is the same as the outer diameter of the shell 1. The top of the water-absorbing cotton sheet 2 is fixed with a plastic film-shaped waterproof layer 3 by adhesive, and the waterproof layer 3 is fixed with the bottom of the shell 1 by adhesive to seal the groove.

[0038] The fixed wing 6 includes a pressing part 61 and two fixed parts 62, and the fixed parts 62 and the pressing part 61 are integrated. The pressing part 61 and the fixed part 62 in the embodiment are both adhesive tapes. The screw rod 11 penetrates the fixed part 62, and the fixed part 62 is pasted on the top of the shell 1 to fix the shell 1. The bottom of the fixed part 62 is provided with adhesive, and the length of the fixed part 62 is greater than the length between the bottom of the pressing plate 4 and the top of the shell 1, so that the fixed part 62 can be pasted on the patient's skin when the water-absorbing cotton sheet 2 abuts against the patient's skin.

[0039] The shell 1 is provided with a water guide strip 5 made of water-absorbing material. One end of the water guide strip 5 penetrates the top of the shell 1 and the pressing plate 4 and extends into the strip-shaped groove 41. The water guide strip 5 is fixed with the pressing plate 4. The other end of the water guide strip 5 away from the strip-shaped groove 41 extends to the fixed part 62. The water guide strip 5 in the embodiment is a long strip-shaped water-absorbing material rolled from a sheet, and a color developing agent is inserted into the other end of the water guide strip 5 away from the strip-shaped groove 41. The color developing agent in the embodiment is a solid that can be dissolved in alcohol and has color. The part of the water guide strip 5 located in the strip-shaped groove 41 is sleeved with a sealing rubber tube 51 made of transparent plastic material. The sealing rubber tube 51 is fixed on the fixed part 62 by adhesive to fix and protect the water guide strip 5. The part of the water guide strip 5 located in the groove is curved to prevent it from being pulled when the pressing plate 4 rotates.

[0040] The specific implementation process is as follows:

[0041] When the blood sampling is about to end, the fixed part 62 is unfolded, the strip-shaped groove 41 is aligned with the blood sampling needle, and the blood sampling hole is offset from the center of the pressing plate 4 and the shell 1. Then the water-absorbing cotton sheet 2 is attached to the patient's skin and a pressure less than the required pressure for pressing hemostasis is applied. Finally, the fixed part 62 is pasted on the patient's skin to fix the shell 1.

[0042] After the blood sampling is finished, the blood sampling needle is pulled out, and the screw rod 11 is rotated forward, so that the pressing plate 4 slides downward and exerts pressure on the blood sampling position to press and stop bleeding. Specifically, the rotation angle of the screw rod 11 is determined according to the required pressure, and the rotation angle is not an integer multiple of 180°, and the screw rod 11 drives the pressing plate 4 downward after being rotated, so that the blood sampling position is pressed and stopped bleeding. When the pressing plate 4 starts to rotate, the upper sharp block 42 of the pressing plate 4 pierces the water bag 13, and part of the disinfectant enters the strip-shaped groove 41 and continuously moves downward with the pressing plate 4. When the pressing plate 4 abuts against the waterproof layer 3, the waterproof layer 3 seals the end of the strip-shaped groove 41. When the posture of the blood sampling position of the patient changes, the disinfectant in the strip-shaped groove 41 will not flow out in large quantities to cause the water guide strip 5 to fail to contact the disinfectant.

[0043] With the increase of the pressing time, the disinfectant flows along the water guide strip 5 under the action of siphon, and gradually wets the water guide strip 5. When the disinfectant reaches the chromogenic agent position, the chromogenic agent dissolves in the water guide strip 5 to form a colored solution, which wets the water guide strip 5 and can be observed from the outside, prompting the patient that the pressing and stopping bleeding time is reached. Specifically, the material of the water guide strip 5 is determined according to the speed of the disinfectant and the chromogenic agent dissolved in the disinfectant, and the time from the disinfectant entering the water guide strip 5 to the colored solution being observed from the outside is 3-5 min.

[0044] After the pressing time is reached, the screw rod 11 is rotated reversely, driving the pressing plate 4 to rotate reversely, and the other sharp block 42 pierces the waterproof layer 3, so that the disinfectant in the inner cavity enters the water-absorbing cotton sheet 2, preventing the water-absorbing cotton sheet 2 from being adhered to the scab and causing the scab to fall off when the hemostasis device is removed. In the embodiment, the disinfectant only enters the water-absorbing cotton sheet 2 after the pressing and stopping bleeding time is reached and the pressing plate 4 is rotated reversely. At this time, the blood sampling hole has been covered by the blood scab, so that the disinfectant will not cause stinging pain when contacting the blood sampling hole. In addition, the disinfectant can also avoid contacting the blood sampling hole too early to dilute the blood in the blood sampling hole and prevent the blood scab from being formed. After the blood scab is formed, the disinfectant flowing out can also disinfect the skin around the blood sampling hole, reducing the infection probability of the blood sampling hole.

[0045] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that, for those skilled in the art, without departing from the technical solutions of the present application, some modifications and improvements can be made, which should also be regarded as the protection scope of the present application. The protection scope of the present application should be subject to the content of the claims, and the specific embodiments in the description can be used to explain the content of the claims.
