AI Technical Summary
Existing enema devices can easily lead to leakage of the drug fluid when the catheter is inserted into the intestine of rats, and a single drug outlet leads to poor absorption of the drug effect.
A multifunctional rat enema was designed, and the drug conduit was connected to the tube head through internal threads and external threads. The diameter of the outer end of the drug conduit was larger than the inner end to avoid leakage of the drug fluid. Multiple grooved liquid outlets were set up in the drug conduit to ensure that the drug intestines enters the multi-directional direction.
It effectively avoids the leakage problem of the drug liquid during catheter insertion, and through the design of multiple liquid outlets, the absorption effect of the drug liquid in the intestine is improved.

Description
Technical Field
[0001] The utility model specifically relates to the technical field of medical experimental instruments, in particular to a multifunctional rat enema. Background Art
[0002] Rats are the most commonly used research organisms in biological research and medical experiments. Rats are usually used for experiments to test the efficacy and effects of drugs on organisms. Enemas are generally used when administering drugs, which facilitate the enema to inject the drugs into the intestines of mice.
[0003] The existing enema is not fully functional and has some technical problems. When the catheter is inserted into the rat intestine and the drug solution is infused, the drug solution is prone to leakage, and there is only one drug outlet hole on the existing catheter, resulting in poor drug absorption effect. Utility Model Content
[0004] The purpose of the utility model is to provide a multifunctional rat enema to solve the current problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional rat enema, comprising a syringe, a push rod is arranged on the right inner side of the syringe, and a rubber head is arranged on the left end of the push rod, a scale line is arranged on the outer side of the syringe, a tube head is arranged on the left end of the syringe, and an external thread component is arranged on the outer side of the tube head, a drug guide tube is arranged on the left end of the tube head, an internal thread component is arranged on the inner side of the right end of the drug guide tube, and the drug guide tube is connected with the external thread component on the tube head through the internal thread component, and a liquid outlet is arranged on the outer side of the left end of the drug guide tube.
[0006] Preferably, the scale lines are provided in multiple groups.
[0007] Preferably, the diameter of the right end of the drug guiding tube is greater than the diameter of the left end of the drug guiding tube.
[0008] Preferably, the left end of the drug guiding tube is provided with a plurality of liquid outlets, and the liquid outlets are in a groove structure.
[0009] Compared with the prior art, the utility model has the following beneficial effects: the multifunctional rat enema device can
[0010] (1) A drug guide tube, an internal thread component, a tube head and an external thread component are provided. The drug guide tube is connected to the external thread group on the tube head through the internal thread component. When the drug guide tube is inserted into the intestinal tract of a rat, the diameter of the port where the drug guide tube is connected to the tube head is larger than the diameter of the outer end of the drug guide tube, thereby preventing leakage during injection of drug solution.
[0011] (2) A drug guide tube and a liquid outlet are provided. After the drug guide tube enters the rat's intestine, the drug solution enters the intestine through the multi-directional liquid outlets, allowing the rat's intestine to absorb more comprehensively. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the figure: 1. injection tube; 2. push rod; 3. rubber head; 4. scale line; 5. tube head; 6. external thread assembly; 7. drug guide tube; 8. internal thread assembly; 9. liquid outlet. DETAILED DESCRIPTION
[0017] 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.
[0018] See also Figure 1-4 The utility model provides a technical solution: a multifunctional rat enema, comprising an injection tube 1, a push rod 2 is arranged on the right inner side of the injection tube 1, and a rubber head 3 is arranged on the left end of the push rod 2, a scale line 4 is arranged on the outer side of the injection tube 1, a tube head 5 is arranged on the left end of the injection tube 1, and an external thread component 6 is arranged on the outer side of the tube head 5, a drug guide tube 7 is arranged on the left end of the tube head 5, an internal thread component 8 is arranged on the inner side of the right end of the drug guide tube 7, and the drug guide tube 7 is connected with the external thread component 6 on the tube head 5 through the internal thread component 8, a liquid outlet 9 is arranged on the outer side of the left end of the drug guide tube 7, when the drug guide tube 7 enters the intestine to inject liquid medicine, since the outer end diameter of the drug guide tube 7 is larger than the inner end diameter, leakage of the liquid medicine can be avoided during injection.
[0019] like Figure 1 As shown, there are multiple groups of scale lines 4, which are convenient for the experimenter to know the injection amount of the liquid medicine in time.
[0020] like Figure 1 and Figure 2As shown, the diameter of the right end of the drug guiding tube 7 is larger than the diameter of the left end of the drug guiding tube 7, so as to avoid leakage of the drug solution when injecting the drug solution.
[0021] like Figure 1 and 2 As shown, there are multiple liquid outlets 9 at the left end of the drug guiding tube 7, and the liquid outlet 9 is a groove structure. After the drug guiding tube 7 is inserted into the rat intestine, when the drug solution is injected through the liquid outlet 9, since the liquid outlet 9 is a groove structure, the liquid outlet 9 is prevented from directly contacting the intestinal wall of the pipeline, and the drug solution cannot be injected.
[0022] Working principle: When using the multifunctional rat enema device, when installing the drug guide tube 7, rotate the drug guide tube 7 to connect the internal thread component 8 on the drug guide tube 7 with the external thread component 6 on the tube head 5. After the drug solution is injected into the injection tube 1, the enema experiment can be carried out. By inserting the drug guide tube 7 into the rat intestine, the enema can be started. Press the push rod 2, and the push rod 2 pushes the rubber head 3 to allow the drug solution to enter the drug guide tube 7. The drug solution enters the rat intestine through the liquid outlet 9 on the drug guide tube 7. Since the outer end of the drug guide tube 7 has a large diameter, leakage of the drug solution is avoided, and the drug solution is injected into the intestine through multiple liquid outlets 9, so that the rat intestine absorbs more comprehensively. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
[0023] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
