Description

Easy Blowpipe Syringe

technical field

The utility model belongs to veterinary medical equipment, and mainly relates to a blowpipe syringe used for long-distance drug administration to medium and large animals.

Background technique

At present, when performing disease diagnosis and treatment on medium-sized and large animals, based on various reasons such as safety, blowpipes are generally used for long-distance injection to complete the anesthesia or treatment of large and medium-sized animals. The existing anesthesia guns and blowpipe injection devices can meet the requirements in use, but generally have the technical problems of complex structure and high manufacturing cost. It is very necessary to develop a simple blowpipe syringe for long-distance drug administration for animals with simple structure, low manufacturing cost and convenient use under the premise of ensuring effective anesthesia and therapeutic effects.

Contents of the invention

The purpose of this utility model is to solve the problems existing in the above-mentioned prior art and combine the actual needs of clinical practice to research and provide a simple blowpipe syringe, which achieves simple structure, low manufacturing cost, convenient and reliable use, and good therapeutic or anesthesia administration effect. Purpose.

The basic design of the utility model is that the plunger assembly is axially movable in the syringe body, the injection needle is fixed on the outside of the front end of the syringe body, and the medicinal liquid is filled in the front end of the syringe body and the plunger assembly. In the cavity formed between the two surfaces, a paraffin plug is fixed and sealed in the pinhole at the front end of the injection needle. The liquid medicine discharge hole is opened on the needle wall at the front side of the injection needle. The elastic sleeve is installed, and the elastic sleeve seals and contains the liquid medicine discharge hole. The front and rear ends of the elastic power-assisted tension sleeve are respectively connected to the front end of the syringe body and the rear end of the plunger assembly, and are elastic when connected. The power-assisted lacing sleeve is provided with a pre-tightening contraction force, thus forming a simple blowpipe syringe.

The utility model has the advantages of simple and reasonable structure, low manufacturing cost, simple and convenient use, good long-distance administration effect, fast injection administration speed, and thorough, clean and sufficient discharge dosage, which improves the anesthesia or treatment of large and medium-sized animals. quality.

Description of drawings

The accompanying drawing is a schematic diagram of the overall structure of a simple blowpipe injector.

Description of part number in the figure:

1. Elastic lacing sleeve, 2. Plunger assembly, 3. Syringe body, 4. Liquid medicine, 5. Injection needle, 6. Liquid medicine discharge hole, 7. Elastic sleeve, 8. Paraffin plugging.

Detailed ways

The best implementation of the utility model will be described in detail below in conjunction with the accompanying drawings. A simple blowpipe syringe, in which the plunger assembly 2 is axially movable in the syringe body 3, the injection needle 5 is fixed on the outer front end of the syringe body 3, and the medicinal solution 4 is filled in the syringe body 3 and In the cavity formed between the front ends of the plunger assembly 2, a paraffin plug 8 is fixed and sealed in the pinhole at the front end of the injection needle 5, and a liquid medicine discharge hole 6 is opened on the needle wall at the front side of the injection needle 5. On the outside, an elastic sleeve 7 is installed at the position of the liquid medicine discharge hole 6. The elastic sleeve 7 seals and contains the liquid medicine discharge hole 6, and the front and rear ends of the elastic booster tension sleeve 1 are respectively connected to the syringe body. 3. On the front end and the rear end of the plunger assembly 2, and when connected, the elastic power-assisted lacing sleeve 1 is provided with a pre-tightening contraction force.

When long-distance administration is used, the simple blowpipe syringe is placed in the blowpipe as a whole, and the plunger assembly 2 faces the blowing end side of the blowpipe. Pneumatic force pushes the syringe out of the blowpipe quickly. When the injection needle 5 penetrates into the cortex of large and medium-sized animals, the animal cortex prevents the elastic sleeve 7 from moving synchronously with the injection needle 5, so that the liquid discharge hole 6 is separated from the elasticity. The blockage of the cover, the injection needle 5 pierces into the animal cortex under the action of inertial force, and at the same time, under the joint action of the flight inertial force and the elastic power-assisted lacing sleeve 1 with pretensioning force, the plunger assembly 2 in the The syringe body 3 moves axially quickly, injects the medicinal solution 4 into the animal body through the injection needle 5 and the medicinal solution discharge hole 6, and completes the long-distance administration of anesthesia or treatment.
