Background
In the clinical diagnosis and treatment work of hospitals, antibiotic medicines are commonly used medicines, in order to ensure the safety of medication, a skin test needs to be carried out on a patient before the medicines are injected, whether the patient has an allergic phenomenon to the antibiotic medicines is determined, reference opinions are provided for the clinical diagnosis and treatment work, and a basis is provided for subsequent diagnosis and treatment schemes and methods. Therefore, in the process of preparing the antibiotic skin test solution, how to ensure the uniformity of the skin test solution concentration is very critical.
At present, when skin test solution is prepared, the conventional operation is to use a disposable 1ml syringe to firstly extract a certain amount of dissolved antibiotic liquid, then extract physiological saline to 1ml, shake up, push off 0.9ml and leave 0.1ml, then add physiological saline to 1ml, shake up until the required skin test concentration is prepared. The shaking method comprises the steps of pumping a small amount of air back to form small bubbles in the injector, enabling the bubbles in the injector to roll from bottom to top to drive liquid to flow by changing the direction of the injector and continuously bouncing the outside of the injector, and finally uniformly mixing the skin test solution. The following defects exist in the preparation process of the skin test solution: because the pipe diameter is little in the 1ml syringe, the bullet bubble degree of difficulty is big, and need consume more time, increase nursing staff's work load, low efficiency, it is poor to lead to the operation compliance easily in clinical busy nursing work, partial nurse and practice nurse are for reducing work load, bubble is not taken back when shaking evenly, only rock the syringe, the degree of consistency of skin test liquid can't be guaranteed, greatly increased the false positive rate of skin test result, and when incessantly flicking the syringe, the syringe needle drops easily and pollutes the phenomenon that probably takes place the needle stick injury even.

The utility model discloses the technical scheme who adopts:
a portable injector special for rapidly mixing skin test solution comprises a needle head and a needle tube, wherein the needle head is arranged on the needle tube, physiological saline and antibiotic liquid are respectively sucked into the needle tube by the needle head, when the skin test solution is required to be injected into a human body, the skin test solution in the needle tube is injected into the human body through the needle head, a drawing rod is movably arranged in the needle tube, a rubber plug is arranged at the front end of the drawing rod, the drawing rod drives the rubber plug to reciprocate in the needle tube, a guide through hole is formed in the center of the drawing rod, a core rod is movably arranged in the guide through hole and reciprocates in the guide through hole, the phenomenon of bending or position deviation of the core rod during movement is avoided by the guide effect of the guide through hole, the front end of the core rod penetrates through the rubber plug and is connected with a conical bump, a conical head matched with the front part is arranged on the conical bump, and the skin test solution in the needle tube can, set up on the plug with toper lug assorted toper appearance groove, utilize the cooperation in toper lug and toper appearance groove, ensure when pull core bar and pull pole, can effectively return in advance between the two and paste tightly, guarantee normal drawing and liquid pushing away, be provided with the sealing washer on toper appearance groove end, the sealing washer suit prevents that the core bar from when reciprocating motion in the direction through-hole, skin test solution flows along the direction through-hole. When the injector is used for pumping liquid, the front end of the core rod is returned to be attached to the rubber plug, the tail ends of the core rod and the drawing rod are pulled backwards, the drawing rod is kept in a static state after the front ends of the core rod and the drawing rod move to a certain position, the core rod is pushed to move back and forth, and then the conical head at the front end of the core rod is driven to move back and forth in the needle tube, so that the conical head can effectively stir physiological saline and antibiotic liquid in the needle tube to be uniformly mixed, skin test liquid with uniform concentration is formed, and the false positive rate of the skin test is greatly reduced.
Furthermore, the needle tube is provided with a liquid volume scale value. The liquid volume scale value is used for observing the content of the needle tube endothelium test solution.
Further, the section of the wide part of the conical head is smaller than that of the rubber plug. The cone head is ensured to have enough moving space in the needle tube, and the physiological saline and the antibiotic liquid medicine in the needle tube can be effectively and uniformly mixed by moving the cone head in a reciprocating way.
Further, the tail end of the core rod is provided with a core seat. The core rod is driven to reciprocate in the guide through hole through the core seat, so that a user can hold the core seat conveniently, and the core seat is convenient to operate and use.
Furthermore, the tail end of the drawing rod is provided with a drawing seat. The drawing seat drives the drawing rod to reciprocate in the needle tube, so that a user can conveniently hold the drawing seat, and the needle tube drawing device is convenient to operate and use.
Furthermore, a rubber ring is arranged in a guide through hole of the pull rod, and the rubber ring is sleeved on the core rod. Effectively ensures that the core bar is not easy to bend or shift when reciprocating in the guide through hole of the drawing rod, and ensures the stability of the movement of the core bar.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the utility model discloses simple structure, high durability and convenient use, through the pull pole, the cooperation design of core bar and conical head, when preparing skin test solution, utilize the core bar to drive conical head reciprocating motion in the needle tubing, make the conical head mix physiological saline and antibiotic liquid effectively and carry out the misce bene, ensure the degree of consistency of needle tubing endothelium test solution, effectively improve the compliance that nursing staff skin test solution prepared standard operation, improve the work efficiency that nursing staff prepared skin test solution, improve the positive rate of skin test result, higher use and spreading value have in actual application.
(2) Can effectively avoid nursing staff to adopt comparatively traditional skin test solution mode of preparation, incessantly flick the syringe outside, lead to the syringe needle to drop easily and probably take place the phenomenon of acupuncture wound even.
