Abstract
The utility model relates to a barbed puncture set, which belongs to fittings of medical instruments and comprises a puncture set body and a steel needle. A liquid medicine channel and an air inlet channel which are isolated from each other are arranged in the puncture set body, and the steel needle is inserted into the puncture set body. The barbed puncture set is characterized in that a barb is arranged on the upper portion of the steel needle. As the puncture set comprises the steel needle and the plastic puncture set body and simultaneously the barb is arranged at the tip of the steel needle, the purpose of self-destroying is achieved. Simultaneously, as the strength of the steel needle is higher than that of a commonly used puncture set, the barbed puncture set is more labor-saving and time-saving when in puncture. The barbed puncture set has the advantages of simple structure, convenience and rapidness in operation, low manufacturing cost and the like, and is suitable for wide popularization and use.
Description
Technical field
This utility model relates to a kind of accessory of medical apparatus and instruments, specifically is the perforator that a kind of transfusion bag is used.
Background technology
Transfusion device is widely used in clinical transfusion, and it mainly is linked in sequence by perforator, separatory bag or dropping funnel, flow regulator, liquid medicine filter and transfusion needle and forms.Because its frequency of utilization is high, though these transfusion devices all are disposable, these transfusion devices can not be realized self-destruction.Therefore some bad medical workers reuse these transfusion devices, thereby cause the medicinal liquid cross-contamination for one's own profit, badly influence patient's life safety.And the perforator of these transfusion devices all is an integral type, and does not have the self-destruction design, therefore need the perforator of existing transfusion device be improved.
The utility model content
The purpose of this utility model is to above-mentioned technical problem, provides a kind of and can realize self-destruction and easy to operate barb type perforator.
The technical scheme that this utility model is adopted in order to achieve the above object is following:
A kind of barb type perforator, it comprises perforator body and draw point, is provided with mutual isolated medicine liquid channel and inlet channel in the perforator body, said draw point is inserted in the perforator body, it is characterized in that said draw point top is provided with barb.
According to the barb type perforator described in this utility model, it is characterized in that said draw point is inserted in the inlet channel and with inlet channel be interference fit.
According to the described barb type perforator of this utility model, it is characterized in that said draw point upper part is solid, end portion is a hollow, its hollow space exceeds the perforator body) and this hollow space lower end communicate with inlet channel, the top communicates with the external world.
According to the barb type perforator described in this utility model, it is characterized in that said perforator body is made up of plastic material.
This utility model also provides a kind of self-destruction type infusion device, it is characterized in that the perforator on this transfusion device is aforesaid barb type perforator.
This utility model is formed through perforator being divided into by draw point and plastics perforator body two parts; Simultaneously barb is set in the draw point tip; Thereby realize the purpose of self-destruction, simultaneously since the intensity of draw point greater than perforator commonly used, more laborsaving when therefore puncturing, save time.The utlity model has advantages such as simple in structure, convenient to operation, cheap for manufacturing cost, be fit to promote the use of widely.
Description of drawings
Fig. 1 is this utility model structural representation.
Among the figure: 1-perforator body, 2-draw point, 3-barb, 4-medicine liquid channel, 5-inlet channel.
The specific embodiment
To combine accompanying drawing that the technical scheme of this utility model is further specified below:
As shown in Figure 1: the barb type perforator, it has comprised perforator body 1 and draw point 2, wherein perforator body 1 adopts plastics to process.Be provided with mutual isolated medicine liquid channel 4 and inlet channel 5 in the perforator body 1.Wherein draw point 2 be inserted in the inlet channel 5 of perforator body 1 and with inlet channel 5 are interference fit.And draw point 2 upper parts are solid, and end portion is a hollow, and its hollow space slightly exceeds perforator body 1.This hollow space communicates with inlet channel 5, and the top of hollow space is that draw point 2 that communicate and this apical position is provided with barb 3 with the external world.Therefore after using, when wanting to extract puncture, be interference fit because draw point 2 is provided with barb and its and perforator body 1, so draw point 2 disengaging perforator bodies 1 and being retained in the infusion bottle, reach the purpose of self-destruction.
This barb type perforator is applicable to various transfusion devices, during practical implementation, only needs to have now the perforator that perforator on the transfusion device changes this barb type into.
