Inner sticky pad type film sealed vacuum hemostix

Abstract

The invention relates to an internal sticky mat membrane vacuum plain tube comprising a vacuum test tube, a seal diaphragm and an elastic cushion. The elastic cushion is arranged in a vacuum test tube chamber, coated with silastic directly, self-shaped and adhered to the inner surface of the seal diaphragm. The seal diaphragm and a test tube mouth are sealed. The outer surface of the seal diaphragm is designed to be concave for paracentetic needle guiding. The design of the built-in elastic cushion ensures that the cushion does not drop off or is polluted easily. In addition, the minimum puncture strength of a paracentetic needle can be realized for equipment protection and easy operation.

Description

technical field [0001] The invention relates to an inner adhesive pad type membrane-sealed vacuum blood collection tube. In particular, it relates to a vacuum blood collection tube with a negative pressure vacuum blood collection tube with an elastic sealing pad structure whose inner surface of a sealing film integrated with a vacuum test tube mouth is directly formed and self-adhesively fixed. technical background [0002] At present, the sealing method of vacuum blood collection tubes used in the mainstream of the market is to insert a rubber plug into the vacuum test tube mouth to achieve sealing and seal the sealing film on the vacuum test tube mouth, and to stick a rubber pad on the outside of the film. Plastic materials are used in the vacuum test tube. However, the sealing method of the rubber plug will lead to vacuum leakage during long-term storage, high cost of outsourcing supporting parts, high toxicity of waste disposal, serious environmental pollution, etc., and...

Problems solved by technology

[0002] At present, the sealing method of vacuum blood collection tubes used in the mainstream of the market is to insert a rubber plug into the vacuum test tube mouth to achieve sealing and seal the sealing film on the vacuum test tube mouth, and to stick a rubber pad on the outside of the film. Plastic materials are used in the vacuum test tube. However, the sealing method of the rubber plug will lead to vacuum leakage during long-term storage, high procurement costs for outsourced supporting parts, high toxicity of waste disposal, serious environmental pollution, etc., and strong puncture force by the needle tip. The pad method often causes problems such as poor bonding and adhesive fragmentation into the vacuum test tube. During the production process, the volatilization of the adhesive causes air pollution and poisons the operators. Toxic gases are also produced during waste incineration to pollute the environment. The rubber pad is not firmly bonded. When it is easy to fall off or crack, blood collection cannot be completed or the blood collection volume is inaccurate. The needle tip puncture resistance is high, and manual operation is time-consuming and labor-intensive. It is easy to accidentally injure the hand and cause infection. In addition, the puncture sampling needle of the equipment is also easy to cause damage.

[0003] In addition, if the surface needs to be disinfected during use, the products of rubber stoppers or rubber pads have many edges and corners and are deep and astringent, so it is not easy to complete them thoroughly and the disinfectant is easy to remain, and the release of toxic gases during waste incineration will cause environmental pollution.
