Abstract
Description
Technical Field
[0001] This utility model belongs to the field of veterinary syringe technology, specifically relating to a syringe extension rod. Background Technology
[0002] A veterinary syringe is a medical device specifically designed for injecting drugs or vaccines into animals. They typically consist of a syringe, needle, and plunger, and are modified and upgraded for specific purposes or other functions. Veterinary syringes are primarily used for injecting vaccines and other medications into animals, and are an indispensable medical device for disease prevention and control in livestock farming and pet ownership. Due to the significant differences in the types of animals used for veterinary injections, compared to medical injection and puncture instruments, veterinary injection and puncture instruments offer a wider variety of specifications and reusable needles.
[0003] When administering intramuscular injections to large animals, the animals often exhibit fear towards the veterinarian and are generally less obedient. In such cases, using a standard syringe for intramuscular injection could injure the veterinarian. Furthermore, the shorter length of standard syringes is often insufficient for practical needs.
[0004] Therefore, this utility model aims to provide a syringe extension rod to overcome the limitations of using short syringes. Utility Model Content
[0005] The purpose of this invention is to provide a syringe extension rod to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A syringe extension rod includes a connector one, an extension tube, a rubber tube, and a connector two connected in sequence; a needle connecting partition is provided at the middle of the inner wall of the connector one, and a needle connecting tube is provided at the center of the needle connecting partition; a front thread and a rear thread are provided on the inner wall of the connector one, and the front thread and the rear thread are respectively located on both sides of the needle connecting partition; an external thread is provided at the front end of the extension tube, and the rear thread of the connector one and the external thread of the extension tube are threadedly connected; a grip handle is provided at the middle and rear section of the extension tube.
[0008] Preferably, the outer surface of the connector is provided with anti-slip threads.
[0009] Preferably, a hose protection spring is provided at the rear end of the extension tube, and the hose passes through the hose protection spring.
[0010] Preferably, a hose protection spring is provided at the front end of the connector two, and the hose passes through the hose protection spring two.
[0011] Preferably, the outer surface of the connector head two is provided with anti-slip threads two.
[0012] Preferably, the end of the second connector is provided with a connection limiting ring.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) The present invention provides a syringe extension rod, which can effectively extend the length of the syringe by adding an extension tube and a rubber tube to the syringe;
[0015] (2) The syringe extension rod provided by this utility model is provided with a tubing protection spring one and a tubing protection spring two at the connection between the tubing and the front and rear ends; it can effectively prevent excessive bending at the connection between the tubing and the front and rear ends, which would cause the liquid to stop flowing.
[0016] (3) The syringe extension rod provided by this utility model has a grip handle that can effectively enhance the grip comfort of this device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] A syringe extension rod includes a connector 1, an extension tube 2, a rubber tube 3, and a second connector 4 connected in sequence. The outer surface of connector 1 has an anti-slip thread 5, which enhances surface friction and facilitates tightening. A needle connection partition 6 is located at the center of the inner wall of connector 1, dividing the inner wall into two parts, each with a front thread 7 and a rear thread 8. The front thread 7 and rear thread 8 are located on opposite sides of the needle connection partition 6. The front thread 7 of connector 1 is used to connect a needle, and the rear thread 8 is used to connect the extension tube 2. The front end of the extension tube 2 has an external thread 9, and the rear thread 8 of connector 1 and the external thread 9 of extension tube 2 are threadedly connected. For ease of gripping, a handle 10 is provided at the middle to rear section of the extension tube 2. To protect the tubing 3, a tubing protection spring 11 is provided at the rear end of the extension tube 2, through which the tubing 3 passes; a tubing protection spring 12 is provided at the front end of the connector 4, through which the tubing 3 passes. The tubing protection springs 11 and 12 effectively prevent excessive bending at the connection points of the tubing 4 with the front and rear ends, thus preventing interruption of the medication flow. An anti-slip thread 13 is provided on the outer surface of the connector 4 for easy tightening. A connection limiting ring 14 is provided at the end of the connector 4, allowing for quick connection to the syringe at the rear end.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
