Abstract
A multi-purpose conversion type artery blood taking needle belongs to the technical field of operation devices. A syringe needle is connected with a needle plug, a clamping ring and a one-way valve are arranged in an inner hole at one end of the needle plug, a part of circle of the one-way valve is connected with the inner hole of the needle plug, the inner diameter of the clamping ring is smaller than the inner diameter of the needle plug, and the diameter of the one-way valve is smaller than the inner diameter of the needle plug. A syringe needle tube and a syringe needle tube head are of an integral structure, a clamping groove is arranged on the periphery of the syringe needle tube head, a syringe needle tube end head is arranged at one end of the syringe needle tube head, and the diameter of the syringe needle tube end head is smaller than the inner diameter of the clamping ring. When the blood taking needle is utilized to conduct arteriopuncture to take a blood specimen, the artery puncture needle is fixed, and other blood specimens can be continuously extracted by simply replacing a syringe needle tube after the artery blood specimen is collected. When a patient requires blood specimen examination and other blood specimen examination, all specimens can be collected by once artery puncture. Therefore, the multi-purpose conversion type artery blood taking needle can reduce pains of a patient and can improve working efficiency of nurses.
Description
Technical field
This utility model relates to a kind of multipurpose conversion type arterial blood drawing pin, belongs to operation device technical field.
Background technology
In various major operation perioperative patients' nursing, gather the arterial blood gas specimen with the respiratory function of assess patient through regular meeting, also can take routine blood test, blood group, blood biochemistry, four of blood coagulations, four of serum, and multinomial blood test specimen such as match simultaneously.Present conventional way is to carry out the collection that other blood specimen is finished in collection that arterypuncture finishes the vim and vigour specimen and venipuncture to the patient respectively, and the patient needs to puncture more than twice at least.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of multipurpose conversion type arterial blood drawing pin.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of multipurpose conversion type arterial blood drawing pin, syringe needle connects pintle, in the end endoporus of pintle snap ring and unidirectional flap valve is arranged, the part circumference of unidirectional flap valve is connected with the endoporus of pintle, the internal diameter of snap ring is less than the internal diameter of pintle, and the diameter of unidirectional flap valve is less than the internal diameter of pintle
Syringe needle tube and syringe needle tube head are structure as a whole, and the circumference of syringe needle tube head has draw-in groove, and an end of syringe needle tube head is the syringe needle pipe end, and the diameter of syringe needle pipe end is less than the internal diameter of snap ring.
A kind of multipurpose conversion type arterial blood drawing pin, syringe needle connect pintle, in the end endoporus of pintle unidirectional flap valve are arranged, and the part circumference of unidirectional flap valve is connected with the endoporus of pintle, and the diameter of unidirectional flap valve is less than the internal diameter of pintle,
Syringe needle tube and syringe needle tube head are structure as a whole, and an end of syringe needle tube head is the syringe needle pipe end.
Advantage of the present utility model is to carry out arterypuncture when taking the vim and vigour specimen to the patient, and fixedly the arterypuncture syringe needle after having gathered ABS, only needs to change a syringe needle tube, but other blood specimen of continuous drawing.When the patient carries out the inspection of vim and vigour specimen and needs other blood specimen to check simultaneously, can arterypuncture of row can gather whole specimen.So not only can reduce patient's misery, also can improve nurse's work efficiency.
Of the present utility model applied widely, so long as the patient who needs collection vim and vigour specimen to gather other blood specimen simultaneously all can use.For pediatric patient more apparent advantage, especially infant, the infant patient is because body weight is little, and it is big that blood vessel carefully reaches relative blood sampling volume, and the collection difficulty of blood preparation is big before the art.When arterial blood drawing is left and taken the vim and vigour specimen, leave and take other blood specimen and more can show superiority of the present utility model.
Description of drawings
When considered in conjunction with the accompanying drawings, by the reference following detailed, can more completely understand this utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide further understanding of the present utility model, constitute a part of the present utility model, illustrative examples of the present utility model and explanation thereof are used for explaining this utility model, do not constitute to improper restriction of the present utility model, wherein:
Fig. 1 is this utility model sketch map.
Fig. 2 is this utility model assembling sketch map.
Fig. 3 is one of structure of the present utility model sketch map.
Below in conjunction with drawings and Examples this utility model is further specified.
The specific embodiment
Obviously, the many modifications and variations done based on aim of the present utility model of those skilled in the art belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1 and Figure 2, and syringe needle 1, syringe needle tube 2, syringe needle tube head 3, unidirectional flap valve 4, snap ring 5, syringe needle pipe end 6, draw-in groove 7, pintle 8.
A kind of multipurpose conversion type arterial blood drawing pin, syringe needle 1 connects pintle 8, in the end endoporus of pintle 8 snap ring 5 and unidirectional flap valve 4 is arranged, the part circumference of unidirectional flap valve 4 is connected with the endoporus of pintle 8, the internal diameter of snap ring 5 is less than the internal diameter of pintle 8, and the diameter of unidirectional flap valve 4 is less than the internal diameter of pintle 8
When pintle 8 was connected with syringe needle tube head 3, syringe needle pipe end 6 fell unidirectional flap valve 4 tops, and snap ring 5 is connected with draw-in groove 7 couplings.
When pintle 8 broke away from syringe needle tube head 3, unidirectional flap valve 4 restored to the original state, and is stuck in the endoporus of pintle 8.
Key point of the present utility model is that pintle 8 endoporus of syringe needle 1 arrange the unidirectional flap valve 4 that increase prevents that arterial blood from flowing out, pintle 8 has snap ring 5 and draw-in groove 7 with syringe needle tube head 3 junctions of syringe needle tube 2, when pintle 8 was connected with syringe needle tube head 3, unidirectional flap valve 4 was in open state.When pintle 8 separated with syringe needle tube head 3, unidirectional flap valve 4 was in closed condition.
