Technical Field
[0001] This utility model relates to the technical field of continuous injection in livestock, and in particular to a bidirectional sealed veterinary liquid medicine container. Background Technology
[0002] In the field of continuous veterinary injections for livestock, because animals often cannot cooperate well, staff need to carry veterinary liquid medications with them for rapid injection. Veterinary liquid medication containers are carried by staff for temporary storage of these medications. Conventional veterinary liquid medication containers have an inlet at the top for refilling; there are two dispensing methods. The first method involves inserting the dispensing tube through the inlet into the container to extract the medication; the second method involves placing the dispensing port near the bottom of the container to discharge the medication. Both methods require a seal at the inlet to prevent external contaminants from entering and contaminating the medication, and to prevent splashing and waste of the medication. However, after a certain amount of veterinary liquid medicine is continuously dispensed from the veterinary liquid medicine container, the pressure inside and outside the container will become unbalanced, preventing the veterinary liquid medicine from being dispensed further.

Detailed Implementation
[0025] Example 1: See Figure 1-4A bidirectional sealed veterinary liquid medicine container includes a sealed barrel 1, a sealed cover 2, and a valve. The sealed barrel 1 has an injection port 11 at the top and an outlet 12 at the bottom. The injection port 11 is used to add veterinary liquid medicine to the container; the outlet 12 is used to discharge the veterinary liquid medicine from the container. Because the outlet 12 is located at the bottom of the sealed barrel 1, the veterinary liquid medicine can be discharged smoothly by its own gravity. The sealed cover 2 is detachably installed on the injection port 11. The valve is installed on the outlet 12 to control the opening and closing of the outlet 12. When the sealed cover 2 is removed and the valve is closed, the veterinary liquid medicine container... It can replenish veterinary liquid drugs; when the valve is closed, the veterinary liquid drug container forms a closed container, which can prevent foreign objects from entering and prevent the internal veterinary liquid drugs from splashing out; when the valve is opened, the veterinary liquid drugs are discharged through the drug outlet 12 for continuous injection in livestock; the top of the closed cover 2 is provided with a through vent 21 to maintain the air pressure balance inside and outside the veterinary liquid drug container; the vent 21 is equipped with a downward-facing duckbill valve 22, which closes the vent 21, allowing external air to enter only when the inside of the veterinary liquid drug container becomes a negative pressure state, thus maintaining the air pressure balance inside and outside the veterinary liquid drug container.
[0026] Compared with the prior art, this utility model seals the injection port 11 with the closed cover 2 and seals the outlet port 12 with the valve, so that the inside of the closed barrel 1 forms a sealed space to prevent the veterinary liquid medicine from being contaminated by the outside and to prevent the veterinary liquid medicine from splashing out and causing waste; the duckbill valve 22 is used to maintain the air pressure balance inside and outside the veterinary liquid medicine container and maintain the continuous output of veterinary liquid medicine.
[0027] The enclosed barrel 1 has a rectangular shape, which facilitates connection with the outside.
[0028] The injection port 11 extends outward and has an injection tube 111 communicating with it, so as to replenish the veterinary liquid medicine container with veterinary liquid medicine; the sealing cap 2 is threadedly connected to the upper end of the injection tube 111, so as to realize the detachable connection between the sealing cap 2 and the upper end of the injection tube 111.
[0029] The inner wall of the sealing cap 2 is provided with an internal thread 23; the outer wall of the injection tube 111 is provided with an external thread 1111 that is threadedly engaged with the internal thread 23; the outer wall of the sealing cap 2 is evenly distributed with a number of friction ridges 24 to increase the friction of the sealing cap 2 and increase the ease of rotation of the sealing cap 2.
[0030] The bottom inner edge of the sealing cap 2 is chamfered 25 to facilitate the threaded connection between the sealing cap 2 and the upper end of the injection tube 111.
[0031] The vent 21 has a stepped hole structure, including a large hole 211 and a small hole 212 arranged coaxially at the top and bottom; the upper end of the duckbill valve 22 extends outward in sequence from the ring body A 221 and the ring body B 222; the ring body A 221 is positioned higher than the ring body B 222; the outer diameter of the ring body A 221 matches the diameter of the large hole 211; the outer diameter of the ring body B 222 is greater than the diameter of the small hole 212; the distance between the ring body A 221 and the ring body B 222 is h1; the depth of the small hole 212 is h2; h1 and h2 match; the sealing cover 2 and the duckbill valve 22 form a convenient snap-fit structure.
[0032] The upper surface of the duckbill valve 22 is flush with the upper edge of the vent 21, which can prevent the duckbill valve 22 from automatically coming off the closed cover 2.
[0033] The outer diameter of ring A 221 is greater than the outer diameter of ring B 222, so that the duckbill valve 22 can be fitted into the vent 21.
[0034] The top outer wall of the sealed cover 2 has a groove 26 at the center; the vent 21 is located at the center of the groove 26; the upper end of the duckbill valve 22 is lower than the upper edge of the groove 26, which can prevent the duckbill valve 22 from being pushed by the outside and disengaging from the vent 21.
[0035] The bottom of the sealed barrel 1 is provided with a downward-facing cone structure 13; the medicine outlet 12 is located at the output end of the cone structure 13; the cone structure 13 collects veterinary liquid medicines, making it easy for the veterinary liquid medicines to be discharged from the medicine outlet 12.
[0036] The valve is a double shut-off valve quick connector 3; when the double shut-off valve quick connector 3 is installed with a pipeline for discharging medicine, the medicine outlet 12 can discharge veterinary liquid medicine; when the double shut-off valve quick connector 3 is not installed with a pipeline for discharging medicine, the medicine outlet 12 cannot discharge veterinary liquid medicine; the double shut-off valve quick connector 3 also essentially functions as a valve.
[0037] The working process of this embodiment includes the following steps:
[0038] ① Add veterinary liquid medication to the veterinary liquid medication container
[0039] Unscrew the cap 2 to expose the injection port 11 at the top of the veterinary liquid medicine container; pour the veterinary liquid medicine into the injection port 11; screw the cap 2 onto the upper end of the injection tube 111 to seal the injection port 11.
[0040] ② Draining veterinary liquid drugs
[0041] The veterinary liquid medicine enters the outlet 12 through the cone structure 13, and then enters the double shut-off valve quick connector 3 through the outlet pipe 121;
[0042] When the quick connector 3 of the double shut-off valve is connected to the discharge pipeline, the veterinary liquid medicine is discharged through the discharge pipeline; as the veterinary liquid medicine is discharged, a negative pressure state is formed inside the veterinary liquid medicine container, the duckbill valve 22 is opened, allowing external air to enter the veterinary liquid medicine container, achieving air pressure balance inside and outside the veterinary liquid medicine container, and ensuring the continuous discharge of veterinary liquid medicine.
[0043] When the double shut-off valve quick connector 3 is not connected to the discharge line, the veterinary liquid medicine will stagnate at the double shut-off valve quick connector 3.
[0044] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that: the medicine outlet 12 extends outward to form a medicine outlet pipe 121 that communicates with the medicine outlet 12; the double shut-off valve quick connector 3 is threadedly connected to the medicine outlet pipe 121, which facilitates the replacement and maintenance of the double shut-off valve quick connector 3.
