CN2062620U - Injection container with spring needle and metallic injector - Google Patents

Abstract

The utility model discloses an injection container with a needle head and a metal injector. A syringe needle head and a plastic container are made into integration; the neck of the container is packaged with the protective sleeve of the needle head with a prestress unsealing pull ring. Physic liquor filled from a charge hole on the bottom of the container is sealed with a ripe melting method. In such way, a disposable injection with the needle head is made out. The injection is loaded and clamped in the frame of the metal injector, and a push rod is pushed to force the plastic outer shell of the injection to be deformed along the axial direction to extrude out the physic liquor to complete the injection. The utility model has high injection safety and greatly reduces injection expenses.

Description

Injection container with spring needle and metallic injector

This utility model belongs to the medical injection apparatus

Syringe that traditional method is used and syringe needle belong to split type, must could continue to use through high-temperature sterilization after using, and belong to permanent use type, and the cross infection of this kind syringe is serious, is replaced by plastic injector for temporary use.Though plastic injector for temporary use can solve the problem of cross infection, but it is not eradicated the pollution channel in the use as yet fully and uses factors such as price is high, there are following two significant disadvantage: one, will from medicine bottle, extract medicinal liquid behind the syringe Kaifeng, often extract shelve behind the medicinal liquid more of a specified duration, the nurse was placed on the drug delivery dolly after night shift room is taken out medicinal liquid earlier when for example injected in the ward, go-cart is patient infusion one by one then, because this process is longer, will certainly cause pin and medicine contaminated; Two, injection cost height, following table (contrast of Wuhan City's in October, 89 retail price) is an example:

Common injection such as An Jibilin only need 0.07 yuan, and injecting charge is but up to more than 0.8 yuan, and such medical expense is extremely uneconomic, also is extremely irrational, bring very big obstacle, the especially more difficult popularization in the rural area to popularizing plastic injector for temporary use.

This utility model is intended to overcome the weak point in the above-mentioned prior art, and a kind of low price is provided, injecting apparatus safe in utilization.

This utility model makes the band needle injection agent container of one by a kind of plastic containers with injection needle and powder charge liquid and the metal squeeze note device of supporting with it repeated life-time service is formed.

The injection container of band syringe needle is as shown in Figure 1: the syringe needle 15 that rustless steel is made is installed in the container neck 18; there is a protective sleeve of syringe needle made of plastic 14 outside; be used for protecting through the syringe needle of strict sterilization and avoid polluting and collision; protective sleeve and container seal with ripe molten method at cervical region 18 places; a needle point sealing-plug 16 made from rubber is arranged in the protective sleeve; to prevent that medicinal liquid from entering in the protective sleeve; the bottom of protective sleeve of syringe needle makes the prestressing force Kaifeng draw ring 13 of the convenient safety again in Kaifeng; the transparent non-toxic medical plastic of shell of tank 12 usefulness is made, and container bottom has a medicine containing opening 19.

Injecting drug use divides water preparation and mixed type injection, can adopt distinct methods to pack into from medicine containing opening.

The water aqua type injecting drug use is respectively charged into the back from medicine containing opening and with ripe molten method medicine containing opening is sealed according to adult and two kinds of dosage of child.

The mixed type injection is provided with a thin film 21 that liquid 24 and powder 22 are separated as shown in Figure 2 at container bottom 1/4 place, the rupture of membranes pin 23 that plastics are made is equipped with in the bottom, during use the rupture of membranes pin is up pushed up, and punctures barrier film, shakes gently to make it mix homogeneously and just can.This injection also can be divided into adult and two kinds of dosage of child.

Metal squeeze note device is as shown in Figure 3: main part is a framework 34, there is one to be used for clamping clip 36 and off-centre that the injection cervical region can folding and to clamp handgrip 35 with little hook 38 in its front portion, there is a push rod 31 at the rear portion, is provided with the locking device of being made up of 3 skewed slots 39 and steel ball 32 at framework and the push rod place of moving.

Using method: as shown in Figure 4, earlier the handgrip 35 of metal squeeze note device is opened left, opened automatically, will be with the needle injection agent to pack in the framework 34 from opening 37 at the effect lower catch hoop 36 of little hook 38, close lower catch hoop 36 and clamp handgrip 35, with the cervical region chucking of band needle injection agent; Draw back prestressing force Kaifeng draw ring 13 again, protective sleeve of syringe needle 14 just is cut open along prestressing force loop wire 17, and needle point sealing-plug 16 promotes push rod 31 along with the protective sleeve that cuts is removed together, and the shell 12 of injection container is discharged bubble along axial deformation.Treat that bubble drains, push rod is turned right gently rotate a little that three uniform steel balls 32 have at least one to rotate and with push rod locking along skewed slot, thereby prevent plastic housing resilience before the inserting needle and suck air.The inserting needle rear push-rod turns left a little, and locking state is removed, and promotes push rod until medicinal liquid is squeezed to the greatest extent.

This utility model is owing to make one with syringe needle and powder charge container, thus when injection, just do not need from medicine bottle, to extract medicinal liquid, not only easy to operate, and eliminated pin and the possible contaminated hidden danger of medicine in the operating process, injection safety is reliable; Also can reduce expense significantly in addition, this utility model only is 1/3～1/2 of a plastic injector for temporary use cost.

This utility model can be widely used in the city medical system owing to safe and reliable, because its low price also extends to the rural area, especially is fit to the use under the adverse circumstances, as the army's field operations and the disaster relief etc.
