Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drug delivery devices, in particular to a drug delivery device. Background Art
[0002] Oral administration, also known as oral administration, is the most commonly used method of administration in animal husbandry. Oral administration has the advantages of simple administration, low production cost of drugs, and relatively cheap price. Existing technology mostly uses syringes to administer drugs orally to animals.
[0003] When forcibly administering drugs to larger animals such as pigs and cattle, the use of a syringe will result in a shallow drug administration site, and the animal will easily spit out the drug through vomiting or tongue peristalsis, making oral administration more difficult. Utility Model Content
[0004] The purpose of the utility model is to provide a drug delivery device to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drug delivery device, comprising: a syringe and a sheath, the syringe is connected to an extension tube, the extension tube is connected to a joint, the extension tube and the sheath are connected through the joint, and the syringe cooperates with the sheath to inject medicine into the esophagus of an animal.
[0006] Preferably, the syringe comprises a syringe, and the syringe is provided with an injection port.
[0007] Preferably, the extension tube is provided with a mounting portion, and the mounting portion is sleeved on the injection port.
[0008] Preferably, a fixing fixture is provided at the mounting portion.
[0009] Preferably, the connector is provided with an interface.
[0010] Preferably, the interface is detachably connected to the extension tube.
[0011] Preferably, the connector is detachably connected to the sheath.
[0012] Preferably, a piston rod is arranged in the syringe.
[0013] The drug delivery device has the following beneficial effects:
[0014] The drug delivery device is a device in which a syringe is filled with injection liquid, the drug is placed in a sheath tube, and then the sheath tube is extended into the esophagus of an animal. The injection liquid is injected into the sheath tube through an extension tube and a joint using a syringe. The injection liquid carries the drug in the sheath tube into the esophagus of the animal. The esophagus is a deeper drug delivery site, making it difficult for the animal to spit out the drug, thereby facilitating drug delivery. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 A three-dimensional diagram of a drug delivery device provided in an embodiment of the present application;
[0016] Figure 2 This is an exploded view of the drug delivery device provided in an embodiment of the present application.
[0017] In the figure: 1. syringe; 2. piston rod; 3. injection port; 4. extension tube; 5. mounting part; 6. fixing fixture; 7. connector; 8. interface; 9. sheath. DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] like Figure 1-Figure 2 As shown, the utility model provides an embodiment of a drug delivery device, including: a syringe, the syringe includes a syringe barrel 1, the syringe barrel 1 is provided with an injection port 3, a piston rod 2 is provided in the syringe barrel 1, by moving the piston rod 2 outward in the syringe barrel 1, the injection liquid can be poured into the syringe barrel 1, and the injection liquid is sprayed out by moving the piston rod 2 inward.
[0020] Among them, the syringe is connected to the extension tube 4, the extension tube 4 is provided with a mounting portion 5, the mounting portion 5 is sleeved on the injection port 3, and a fixing clamp 6 is provided at the mounting portion 5. The fixing clamp 6 can fix the mounting portion 5 to the injection port 3 to prevent the extension tube 4 from falling off the syringe after being pulled.
[0021] Further, the extension tube 4 is connected to the connector 7, and the connector 7 is provided with an interface 8, which is detachably connected to the extension tube 4, and the connection methods include but are not limited to sleeve connection and snap connection. Preferably, the interface 8 is snap-connected to the extension tube 4.
[0022] Specifically, the connector 7 is detachably connected to the sheath 9, and the connection methods include but are not limited to socket connection and threaded connection. Preferably, the connector 7 is threadedly connected to the sheath 9, and an internal thread can be opened on the inner wall of the connector 7, and an external thread can be opened on the outer wall of the sheath 9, wherein the sheath 9 can select a model according to the size of the drug, and the extension tube 4 is connected to the sheath 9 through the connector 7, so that the extension tube 4, the connector 7 and the sheath 9 are connected.
[0023] In this embodiment, the syringe cooperates with the sheath tube 9 to inject the drug into the animal's esophagus. First, the piston rod 2 is moved outward to fill the syringe 1 with the injection liquid, and then the drug is placed in the sheath tube 9. The sheath tube 9 is inserted into the animal's esophagus, and the piston rod 2 is moved inward. The injection liquid enters the extension tube 4 from the syringe 1 through the injection port 3, and then enters the sheath tube 9 from the extension tube 4 through the connector 7. The injection liquid carries the drug in the sheath tube 9 into the animal's esophagus. The esophagus is a deeper administration site, which makes it difficult for the animal to spit out the drug, thereby facilitating administration.
[0024] In this embodiment, the sheath tube 9 can be removed from the connector 7 and replaced. When the animal bites through the sheath tube 9, the applicator can continue to be used by replacing the sheath tube 9.
[0025] Working principle: first, the piston rod 2 is moved outward to fill the syringe 1 with injection liquid, and then the drug is placed in the sheath tube 9, the sheath tube 9 is inserted into the animal's esophagus, and the piston rod 2 is moved inward. The injection liquid enters the extension tube 4 from the syringe 1 through the injection port 3, and then enters the sheath tube 9 from the extension tube 4 through the connector 7. The injection liquid carries the drug in the sheath tube 9 into the animal's esophagus.
[0026] In summary, although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
