Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a detachable venous puncture hemostatic presser. Background Art

[0002] In the process of testing and treating patients, blood samples are usually collected from the vein for testing, intravenous infusion is used for medication and even clinical rescue. Effective compression after venous puncture and needle removal is the premise for protecting the patient's blood vessels, alleviating the patient's pain and discomfort, and ensuring the success of the next puncture. Improper compression after venous puncture can easily cause skin bleeding and subcutaneous congestion. At present, there are two methods for stopping bleeding after human blood vessel puncture: one is to use a cotton swab, paper column, and gauze column "two-point one-line method" to compress the puncture point. The other method is to directly use fingers to press the infusion patch that has been covered on the puncture point in advance. There are two problems. One is that the compression position changes after changing hands and the compression force disappears when changing hands, causing subcutaneous congestion or hematoma; the second is that the patient or family members may be contaminated with blood when taking over, which can easily cause cross infection.

[0003] Therefore, a convenient size-adjustable, detachable venous puncture hemostasis presser is urgently needed. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-4 The detachable intravenous puncture hemostatic presser shown in the figure comprises a fixing belt 1, one end of the fixing belt 1 is fixedly connected to a tooth seat 2, a first tooth 3 is arranged on the outer side of the other end of the fixing belt 1, an annular groove 4 is arranged inside the fixing belt 1, a slot 41 is arranged on one side of the annular groove 4, an adjusting groove 21 is arranged inside the tooth seat 2, the inner wall size of the adjusting groove 21 matches the outer wall size of the fixing belt 1, a mounting groove 22 is arranged on the top of the adjusting groove 21, a tooth unlocking rod 24 is rotatably connected inside the mounting groove 22, both sides of the tooth unlocking rod 24 are rotatably connected to a spring shaft 242, connecting holes 23 are arranged on both sides of the inner wall of the mounting groove 22, the outer wall of the spring shaft 242 is fixedly connected to the inner wall of the connecting hole 23, a second tooth 241 is arranged on one end of the tooth unlocking rod 24, the second tooth 241 is engaged and fixed with the first tooth 3, when in use, a disposable hemostatic pad 5 is inserted into the inner wall of the annular groove 4 through the slot 41, and a disposable cotton ball is embedded in the inner wall of the limiting groove 51, After the intravenous puncture needle is pulled out, the cotton ball is pressed on the puncture point, and then the fixing belt 1 is wrapped around the arm, and one end of the fixing belt 1 is inserted through the inner wall of the adjusting groove 21. According to the thickness of the patient's arm, one end of the fixing belt 1 is pulled to tighten it. Under the action of the elastic force of the spring shaft 242, the second latch tooth 241 is driven to rotate downward and engage and fix with the first latch tooth, so that the inner hemostatic pad 5 is fixed on the puncture point by the cotton ball. After the pressing is completed, the latch tooth unlocking rod 24 is pressed down, thereby driving the second latch tooth 241 to rotate around the spring shaft 242, thereby driving the second latch tooth 241 to disengage from the first latch tooth 3. At this time, one end of the fixing belt 1 can be pulled out from the inner wall of the adjusting groove 21, so that the fixing belt 1 and the hemostatic pad 5 are out of contact with the patient's arm. At this time, the cotton ball on one side of the hemostatic pad 5 can be removed and discarded, and the hemostatic pad 5 is checked to see if it is stained with blood. If it is stained, it is discarded. If it is not in contact with blood, it is soaked in chlorine-containing disinfectant and reused to reduce consumables.

[0019] The number of the second latch teeth 241 and the first latch teeth 3 are both set to be multiple, and the multiple second latch teeth 241 are equidistantly distributed in a linear shape at one end of the latch tooth unlocking rod 24, and the multiple first latch teeth 3 are equidistantly distributed in a linear shape on the outside of the fixing belt 1. One side of the fixing belt 1 is flush with one side of the latch tooth seat 2 to reduce the indentation on the patient's arm. A hemostatic pad 5 is clamped inside the annular groove 4. The hemostatic pad 5 is set to a shape that is thin in the middle and thick at both ends, and is used to be clamped with the inner wall of the annular groove 4. The size of the middle part of the hemostatic pad 5 is smaller than the inner diameter of the annular groove 4 and larger than the width of the slot 41. A limiting groove 51 is provided at one end of the hemostatic pad 5 to embed a cotton ball.

[0020] In summary, the utility model has the following working principle: when in use, the disposable hemostatic pad 5 is inserted into the inner wall of the annular groove 4 through the slot 41, and the disposable cotton ball is embedded in the inner wall of the limiting slot 51. After the intravenous puncture needle is pulled out, the cotton ball is pressed on the puncture point, and then the fixing belt 1 is wrapped around the arm, and one end of the fixing belt 1 is inserted through the inner wall of the adjusting slot 21. According to the thickness of the patient's arm, one end of the fixing belt 1 is pulled to tighten, and under the action of the elastic force of the spring shaft 242, the second clamping tooth 241 is driven to rotate downward and is clamped and fixed with the first clamping tooth, so that the inner hemostatic pad 5 is pressed on by the cotton ball. The puncture point is fixed. After the pressing is completed, the locking tooth unlocking rod 24 is pressed down, thereby driving the second locking tooth 241 to rotate around the spring shaft 242, thereby driving the second locking tooth 241 to disengage from the first locking tooth 3. At this time, one end of the fixing belt 1 can be pulled out from the inner wall of the adjustment groove 21, thereby making the fixing belt 1 and the hemostatic pad 5 disengage from the patient's arm. At this time, the cotton ball on one side of the hemostatic pad 5 can be removed and discarded, and the hemostatic pad 5 can be checked to see if it is stained with blood. If it is stained, it can be discarded. If it is not in contact with blood, it can be soaked in chlorine-containing disinfectant and reused to reduce consumables. This completes the overall workflow of the device.
