Problems solved by technology

[0002] Magnetic resonance examinations often require enhanced scanning, but because some parts of the examination require the use of Tim coils to fix the arms or some patients are often unable to press the puncture site with their fingers to stop bleeding due to neurological diseases, and the special examination of magnetic resonance is inconvenient for family members. Accompanied by the patient, using the traditional cotton swab to pressurize hemostasis will cause many patients to have subcutaneous blood stasis and hematoma
Repeated blood vessel bleeding causes various blood components to leak out, which can cause connective tissue hyperplasia, resulting in thickening and hardening of the vessel wall, increasing pain for the patient and making it difficult for the next venipuncture

Embodiment 1

[0018] Such as figure 1 As shown, the constant-pressure arteriovenous puncture hemostasis device includes at least one fixing belt 1, and there is an air bag 2 on the fixing belt 1. The air bag is a cuboid and is fixed along the length of the fixing belt; Connection; air pump control unit.

[0019] Such as figure 2 As shown, the air pump control unit 4 includes a button control circuit 401, an air pump control circuit 402, a solenoid valve control circuit 403 and a power supply circuit 404. The key control circuit 401 is a single-chip microcomputer, and the input port of the single-chip microcomputer is connected with a button K1 and a button K2. The first output port is electrically connected with the air pump control circuit 402; the second output port of the single-chip microcomputer is electrically connected with the solenoid valve control circuit 403; Connection; the solenoid valve 406 and the air pump 405 communicate with the air bag 2 through the hose 3 .

Abstract

The invention relates to a hemostasis device, in particular to a constant-pressure type arteriovenous puncturing hemostasis device. The constant-pressure type arteriovenous puncturing hemostasis device is characterized by comprising at least one fixing belt and an air pump control unit, wherein an air bag is arranged on the fixing belts, is in an oblong shape, and is fixed along the length direction of the corresponding fixing belt, and the air bag is connected with an air pump control unit through a hose pipe. Compared with the existing hemostasis, the constant-pressure type arteriovenous puncturing hemostasis device has the characteristic that the safety and convenience are realized.

Description

technical field [0001] The invention relates to a hemostatic device, in particular to a constant-pressure arteriovenous puncture hemostatic device. Background technique [0002] Magnetic resonance examinations often require enhanced scanning, but because some parts of the examination require the use of Tim coils to fix the arms or some patients are often unable to press the puncture site with their fingers to stop bleeding due to neurological diseases, and the special examination of magnetic resonance is inconvenient for family members. Accompanied by the patient's side, using the traditional cotton swab to pressurize the hemostasis will cause subcutaneous bleeding and hematoma in many patients. Repeated bleeding of blood vessels causes various blood components to ooze out, which can cause connective tissue hyperplasia, resulting in thickening and hardening of the vessel wall, increasing pain for patients and making it difficult for the next venipuncture. Contents of the i...
