Description
Technical field
This utility model is specifically related to the special empty needle of a kind of skin test.
Background technology
In hospital clinical, not having special skin test empty needle, be all use the empty needle of 1ml to replace, but the skin test collocation method that we commonly use is all adopt to take out the method that three push away two, the solution for skin test for the last time then for configuring.In the process of configuration skin test, there are two shortcomings: carry out puncture extraction diluent liquid and aerofluxus frequently, skin test medicament mixed can be made uneven and easily contaminated, sometimes cause syringe needle to come off; The setup time of solution for skin test is long, not only brings the work of repetition to nursing staff, also easily causes unnecessary to protect trouble contradiction.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of skin test special empty needle, and to solve that skin test medicament mixed is uneven, setup time is long and easily contaminated, and syringe needle holds caducous problem.
For achieving the above object, technical solution adopted in the utility model is: provide a kind of skin test special empty needle, comprise syringe of getting it filled, auxiliary needle cylinder and skin test syringe, its upper end of getting it filled is communicated with auxiliary needle cylinder lower end by valve III, and auxiliary needle cylinder upper end is communicated with skin test syringe lower end by valve II; Syringe lower end of getting it filled is communicated with by valve IV syringe needle of getting it filled, skin test its upper end is communicated with dismountable skin-test needle by valve I, skin test syringe lower end is provided with the sterile sealing lid for covering valve II, and syringe of getting it filled, auxiliary needle cylinder and skin test syringe inside are all preinstalled with normal saline and are vacuum.
As preferably, the normal saline of syringe of getting it filled, auxiliary needle cylinder and skin test syringe inside prepackage has 0.9ml.
As preferably, get it filled syringe needle and skin-test needle are equipped with pin cap.
As preferably, skin-test needle is provided with the graduation mark being convenient to control injected dose.
the beneficial effects of the utility model are:
1, its upper end of getting it filled of the present utility model is communicated with auxiliary needle cylinder lower end by valve III, and auxiliary needle cylinder upper end is communicated with skin test syringe lower end by valve II; Described syringe lower end of getting it filled is communicated with by valve IV syringe needle of getting it filled, skin test its upper end is communicated with dismountable skin-test needle by valve I, skin test syringe lower end is provided with the sterile sealing lid for covering valve II, and syringe of getting it filled, auxiliary needle cylinder and skin test syringe inside are all preinstalled with normal saline and are vacuum.Syringe needle of getting it filled inserts after in skin test medication, opens valve IV, valve III and valve II successively, can obtain required skin test medicinal liquid in skin test syringe.This device can make required skin test medicinal liquid simply, fast, accurately, and skin test medicinal liquid does not contact with extraneous air and can not be polluted in layoutprocedure.Syringe needle of getting it filled only once is got it filled, and skin-test needle only carries out the injection of skin test, and the situation of accidental appears in can avoid getting it filled syringe needle and skin-test needle.
2, the normal saline of syringe of getting it filled of the present utility model, auxiliary needle cylinder and skin test syringe inside prepackage has 0.9ml, can ensure syringe, auxiliary needle cylinder and the skin test syringe accuracy at configuration skin test medicinal liquid of getting it filled.
3, get it filled syringe needle and skin-test needle of the present utility model are equipped with pin cap, pin cap can play a protective role to get it filled syringe needle and skin-test needle, and avoid getting it filled syringe needle and skin-test needle are damaged or pollute before use.
4, skin-test needle of the present utility model is provided with the graduation mark being convenient to control injected dose, and medical worker holds injected dose by the graduation mark on skin-test needle in the process to sufferer injection skin test medicinal liquid, can ensure the accuracy of skin test liquid medicine injection dose.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein: 1, sterile sealing lid; 2, skin-test needle; 3, valve I; 4, skin test syringe; 5, valve II; 6, auxiliary needle cylinder; 7, valve III; 8, to get it filled syringe; 9, valve IV; 10, to get it filled syringe needle; 11, pin cap.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with this utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, the present embodiment provides a kind of skin test special empty needle, comprise syringe 8 of getting it filled, auxiliary needle cylinder 6 and skin test syringe 4, syringe 8 upper end of getting it filled is communicated with auxiliary needle cylinder 6 lower end by valve III 7, and auxiliary needle cylinder 6 upper end is communicated with skin test syringe 4 lower end by valve II 5; Syringe 8 lower end of getting it filled is communicated with by valve IV 9 syringe needle 10 of getting it filled, skin test syringe 4 upper end is communicated with dismountable skin-test needle 2 by valve I 3, skin test syringe 4 lower end is provided with the sterile sealing lid 1 for covering valve II 5, and syringe 8 of getting it filled, auxiliary needle cylinder 6 and skin test syringe 4 inside are all preinstalled with 0.9ml normal saline and are vacuum.Get it filled on syringe needle 10 and skin-test needle 2 and be equipped with pin cap 11.Skin-test needle 2 is provided with the graduation mark being convenient to control injected dose.
In implementation process, syringe needle 10 of first getting it filled inserts after in skin test medication opens valve IV 9, and syringe 8 of getting it filled sucks the skin test medication of 0.1ml under the effect of inner vacuum negative pressure.Then open valve III, auxiliary needle cylinder 6 sucks the medicinal liquid that 0.1ml gets it filled in syringe 8 under the effect of inner vacuum negative pressure.Finally open valve II, skin test syringe 4 sucks the medicinal liquid in 0.1ml auxiliary needle cylinder 6 under the effect of inner vacuum negative pressure, and the medicinal liquid in skin test syringe 4 is required skin test medicinal liquid.
Skin test syringe 4 and auxiliary needle cylinder 6 are separated, valve II is stayed on skin test syringe 4, to be covered by valve II and open valve I 3 with sterile sealing lid 1.Undertaken in the process of skin test by skin-test needle 2, injecting 0.1 ~ 0.2ml skin test medicinal liquid by the 1 pair of sufferer of sterile sealing lid under hand, then changing skin-test needle 2 and carry out skin test next time.
As long as this device has been broken do the fixing thinking that skin test just must use 1ml empty needle, and this device have volume little, be easy to place, use simple and dosage to configure advantage accurately, avoid in skin test layoutprocedure because of the pollution of skin test medicinal liquid of repeatedly aspirating, aerofluxus may cause, the dose error existed when avoiding human configuration solution for skin test, shortens patient's waiting time.Skin-test needle 2 can be changed immediately after misoperation causes syringe needle to pollute, and guarantees that patient one pin one is with avoiding cross infection simultaneously.
Above-mentioned embodiment is used for explaining and this utility model is described; instead of this utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make this utility model and change, all fall into protection domain of the present utility model.
