Abstract

The utility model is a rubber-plastic composite film packaging negative pressure blood collection tube for various testing blood collection, and comprises a transparent plastic pipe and a rubber-plastic composite sealing film. The nozzle of the transparent plastic pipe has a thickening part and the rubber-plastic composite sealing film is formed by the composite of a butyl rubber layer and a plastic film layer. The transparent plastic pipe with the thickening part at the nozzle and the rubber-plastic composite sealing film are hard combined into a whole through the hot plastic packaging method. The upper layer of the rubber-plastic composite sealing film is the butyl rubber layer which plays a sealing role and can recover after acupuncture to keep the vacuum, and the lower layer is the plastic film layer which is used to make a thermoplastic adhesion with the plastic test tube and strengthen the vacuum holding performance of the composite film. The vacuum holding period of products is more than two years. The technology can significantly reduce the production cost and price of the blood collection tubes.

Description

Rubber and plastic composite membrane packaged type negative pressure blood taking tube

(1) technical field: this utility model relates to a kind of negative pressure blood taking tube, and particularly rubber and plastic composite membrane packaged type negative pressure blood taking tube is applicable to all kinds of anticoagulant collections and check, belongs to technical field of medical instruments.

(2) background technology:

The negative pressure blood taking tube is generally adopted in beginning on the domestic and international market at present, and its structure all is by glass or transparent plastic test tube, and medical poisonless butyl rubber bung, colour are moulded medicated cap three parts and constituted; And wherein the cost of butyl rubber bung accounts for the over half of blood taking tube cost, and butyl rubber is again the import goods and materials, with the large, medium and small hospital in the whole nation, and a large amount of uses of negative pressure blood taking tube, butyl rubber will become goods and materials in short supply.

(3) summary of the invention:

The purpose of this utility model is too high and prevent the pollution problem of blood taking tube content for the cost that solves present medical negative pressure blood taking tube, this utility model provides a kind of rubber and plastic composite membrane packaged type negative pressure blood taking tube, structure is made of lucite pipe (1) and rubber and plastic compound seal film (2) as Figure 1-3; Lucite pipe (1) oral area has reinforcement (1a), and rubber and plastic compound seal film (2) is by butyl rubber layer (2a) and two-layer being composited of plastic membranous layer (2b); The lucite pipe (1) of mouth of pipe band reinforcement (1a) and rubber and plastic compound seal film (2) are put in advance in the lucite pipe (1) and are conformed to agent with firm being combined as a whole of thermoplastic packaged type, and conforming to agent is anticoagulant or coagulant, decides with inspection item.Evacuation in vitro, the test tube outer wall sticks the label that is used to put down in writing inspection item.

The rubber and plastic composite membrane is superposeed bonding the composition by medicinal butyl rubber layer and plastic film layers, total thickness has only 0.5～1.0mm, be compressed to finished product in advance, the disk of tailoring to equating with test tube mouth size uses, and the upper strata is a rubber layer, seal, can restore again after the acupuncture, to keep vacuum, lower floor is a plastic film layers, be used for transparent plastic test tube thermoplastic bondingly, open and strengthen laminated film to keep vacuum performance.The reinforcement of test tube mouth (1a) can increase the bonding area of rubber and plastic compound seal film and increase test tube intensity greater than 2 years the empty phase of the fidelity of product.

One of advantage of the present utility model is to reduce the production cost and the price of blood taking tube significantly, simplifies production technology, saves a large amount of import butyl rubber materials, reduces cost, has simplified operation again, is more suitable in automatic assembly line production.It two is the sealing ways that the empty phase of its seal degree and fidelity are better than rubber stopper greatly, its three categories of etiologic factors industry standard code: not handy hands touches stopper, external product has also increased safety helmet for this reason, this has just more increased manufacturing process complexity and production cost, the production use of this product all is suitable for mechanical way and can eliminates manual operations, so do not need to increase safety helmet.It is four because of the rubber and plastic composite membrane is thin than plug, and the blood sampling puncture is just easier.

The negative pressure hemostix has begun to popularize in an all-round way at home to be popularized, and manufacturer will face the market competition widely, and the focus of the market competition is price:

The negative pressure hemostix of import (is representative with the U.S. company BD product), 2.20 yuan/of its blood taking needles, 1.14 yuan/of negative pressure blood taking tubes (adding up to 3.60 yuans/cover), present home-made negative pressure hemostix (is example with Beijing and liuyang hunan product), the every cover producer price of its product is about 1.20 yuan, wherein the negative pressure blood taking tube is 0.65 yuan/, 0.55 yuan/of blood taking needle.But the at present domestic plastic injector for temporary use blood sampling of also using in tradition, its totle drilling cost is less than 0.60 yuan/cover (syringe, test tube and additives etc.), for this reason, popularize in an all-round way and use negative pressure technique is not only the problem of traditional habit, and main is price problem.China is a underdeveloped developing country still, and the numerous common people's living standard, medical level and medical treatment cost must not be compared with developed countries, popularize the negative pressure blood collecting technology comprehensively, and it is crucial how reducing its cost and price significantly.

Rubber and plastic composite membrane packaged type negative pressure blood taking tube, its total material cost is that (wherein plastic tube 0.06 about 0.10 yuan/, composite membrane 0.03, label 0.01), the selling price of dispatching from the factory will be below 0.20 yuan/, its price will be 1/3 of a homemade goods, and 1/6 of imported product will have great competition (comprising the competition with conventional syringe) potentiality undoubtedly.

China is the big country of one more than 10 hundred million population, the social need amount of hemostix is huge, the demand in metropolitan hospital every year will be hundreds thousand of, up to a million and (adopt multinomial order blood sampling especially now, each patient need adopt many blood samples, need many negative pressure blood taking tubes, this utility model will be brought into play great economic benefit and social benefit undoubtedly so.

(5) specific embodiment:

Fig. 1～3rd, enforcement illustration of the present utility model, oral area has the lucite pipe (1) of reinforcement (1a), butyl rubber layer (2a) and plastic membranous layer (2b) are through the superimposed bonding rubber and plastic compound seal film that total thickness is 0.5～1.0mm of making, plastic tube bottom spray additives (anticoagulant or coagulant) with lucite pipe (1) oral area end face and rubber and plastic compound seal film in automatic machine equipment, evacuation and thermoplastic encapsulate.
