Tourniquet for artery and vein puncture

Abstract

The invention provides a tourniquet for artery and vein puncture, relating to a body bleeding stopping device. The tourniquet comprises an air sac, adhesive tapes and bonding ensuring skins, wherein the air sac is shaped like a plastic spheroid with a one-piece injection sealing air hole; the adhesive tapes comprise an upper adhesive tape and a lower adhesive tape; the upper adhesive tape is longer than the lower adhesive tape; after the middle parts of the upper and lower adhesive tapes are respectively bonded on the air sac in a semi-circumferentially wrapping manner, the upper and lower adhesive tapes are bonded with each other, so that the upper and lower adhesive tapes and the air sac are fixedly bonded; and the two plastic film bonding ensuring skins as wide as the upper adhesive tape are respectively pasted on the two blank parts, which are not bonded with the lower adhesive tape, of the upper adhesive tape. The tourniquet has the following advantages: the defects that the manually compressed positions are not correct, the compression time is hard to master, the compression forces are inconsistent, the patients need to maintain a certain passive posture during compression and the like are overcome, so that patient limb fatigue and discomfort caused by the situation that the patients need to maintain the stereotypic posture for a longer time can be avoided; and the tourniquet is convenient to use, is safe and greatly reduces the nursing workload.

Description

Technical field: [0001] The invention relates to a human body hemostatic device, in particular to an arteriovenous puncture tourniquet. Background technique: [0002] The current situation of arteriovenous puncture hemostasis: At present, in clinical medical work, venipuncture of extremities, such as intravenous infusion, venous blood collection, intravenous injection of drugs, etc., after puncture, the method of manually pressing the venipuncture site is used to achieve local hemostasis. However, in the manual pressing method, there will be inaccurate pressing positions, poor grasp of pressing time, inconsistent pressing intensity, and the patient will maintain a certain passive posture when pressing. Improper pressing or pressing too lightly or for too short a time may easily lead to bleeding at the puncture site and local hematoma; excessive pressing pressure or too long pressing time may cause local pain to aggravate; when manual pressing, the patient needs to maintain a...
