Abstract
The utility model relates to a three-way puncturing needle, belonging to a disposable medical device. The utility model is particularly suitable for the situation of carrying out optical photon treatment in the process of transfusion. The three-way puncturing needle is formed by that the back part of a puncturing needle head is combined with a three-way tube; the three-way tube comprises a straight tube which is straightly communicated with the puncturing needle head; the head of the three-way pipe is provided with two needle holders which can be connected to a spare sealing block, a transfusion tube or an optical-fibre needle. The three-way optical-fibre needle solves the problem of simultaneously carrying out optical blood vessel internal irradiation treatment and transfusion, having the advantage of convenient operation, and pollution can be effectively avoided.
Description
This utility model relates to a kind of threeway puncture needle, belongs to disposable medical apparatus and instruments.
When carrying out the irradiation treatment of blood optical photon therapy clinically, one of method is that the optical fiber pin is directly inserted irradiation operation in the blood vessel, and when the patient who accepts this treatment need infuse, often needs to puncture separately, increases misery to patient.
The purpose of this utility model is to provide a kind of threeway puncture needle, so that transfusion is carried out at the same time with quantum of light irradiation treatment or avoid repeated puncture when hocketing.
The technical solution of the utility model is that the threeway puncture needle is made up of syringe needle, needle stand and tee T, at the rear of syringe needle in conjunction with tee T, tee T comprises straight tube and a bypass branch straight-through with piercing needle, the threeway tube head is established two needle stands, needle stand can be connected with backup seal is stifled, also can be connected with tube for transfusion or optical fiber pin.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a threeway puncture needle sketch map;
Among the figure 1, syringe needle 2, straight tube 3, arm 4, needle stand
5, stifled 6, the puncture needle handle of sealing
Three-way interface place among the figure should try one's best nearer apart from syringe needle, and straight tube leads directly to be suitable for cooperating with syringe needle and inserts optical fiber pin or optical fiber remaining needle, and the general external transfusion device of arm has several situations during use:
If 1. illumination is carried out in transfusion more earlier, then straight tube inner fiber pin can be pushed into the three-way interface place, in case the non-return blood coagulation;
2. carry out illumination earlier and infuse again, the optical fiber pin is pushed into the anterior syringe needle of three-way interface place;
3. transfusion is carried out simultaneously with illumination, then the optical fiber pin is placed the rear portion at three-way interface place, so that the liquid of input just connects back illumination before arriving blood vessel.
This threeway puncture needle, easy to use, simple to operate, can prevent from effectively to pollute.
