AI Technical Summary
During the production process, existing infusion sets are prone to blockage at the connection between the drip pot and the hose, resulting in uneven dripping and affecting the infusion effect. In particular, it may cause side effects such as arrhythmia for patients with poor heart function. In addition, the initial liquid drop is prone to cause excessive flow rate, affecting the infusion effect.
A circular array of grooves is set at the connection between the drip pot and the hose to accommodate excess glue residue, and an H-shaped overflow step is set on the inner side of the lower end of the drip pot to prevent excessive flow rate. These designs can prevent accidents caused by blockage and impact.
It achieves precise control of dripping, avoids problems of uneven dripping and excessive flow rate, improves the safety and stability of infusion, and reduces the occurrence of side effects.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a precise dropper infusion device. Background Art
[0002] An infusion set is a common medical consumable. After sterilization, it establishes a channel between the vein and the medication solution and is used for intravenous infusion. It generally consists of eight connected parts: an IV needle or injection needle, a needle cap, an infusion hose, a medication filter, a flow regulator, a drip pot, a bottle stopper puncture device, and an air filter. Some infusion sets also have an injection device and a dosing port.
[0003] During the production process of existing infusion sets, the connection between the drip pot and the hose is prone to being blocked to a certain extent or completely blocked due to glue coating problems, resulting in uneven dripping during actual use of the infusion set, which can easily lead to side effects such as irregular heartbeat when the patient has poor heart function. In addition, the uneven dripping can easily cause impact when the early liquid falls to the bottom, which can accelerate the liquid flow rate and affect the infusion.
[0004] Based on the above reasons, this design proposes a precise dropper infusion device. Summary of the Invention
[0005] The purpose of the utility model is to provide a precise dropper infusion device.
[0006] To achieve the above-mentioned purpose, the utility model is realized through such a technical solution, a precision dropper infusion device, including an intravenous needle, a needle cap, a hose, a liquid medicine filter, a flow rate regulator, a bottle stopper puncture device, an air filter, and also a drip pot, the upper end of the drip pot is connected to the hose, and a dropper is provided on the inner side of the upper end of the drip pot, the dropper is connected to the hose, and the connection is coated with glue, a plurality of grooves are provided on the outer surface of the hose at the connection, and the grooves are distributed in a circular array, and an overflow step is provided on the inner side of the lower end of the drip pot.
[0007] Furthermore, the overflow step is H-shaped, with the upper side being shorter and the lower side being longer, and the upper end and the left and right ends of the overflow step protrude outward.
[0008] Furthermore, the lower end of the overflow step is connected to the hose.
[0009] Furthermore, the groove is arranged in a vertical strip shape.
[0010] The beneficial effects of the above scheme are:
[0011] The utility model can accommodate excess glue residue during glue application through the annular distribution of grooves, prevent glue from clogging the hose or dropper, thereby avoiding uneven dripping in subsequent use, and thus achieving the purpose of precise dripping. The setting of the overflow step can also prevent the impact of the early dripping from causing excessive flow rate and causing some unexpected situations. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto. Example
[0017] like Figures 1 to 3 As shown, a precise dropper infusion device includes an intravenous needle, a needle cap, a hose, a liquid medicine filter, a flow rate regulator, a bottle stopper puncture device, an air filter, and a drip pot 1. The upper end of the drip pot 1 is connected to the hose 2. The inner side of the upper end of the drip pot 1 is provided with a dropper 3. The dropper 3 is connected to the hose 2 and glue is applied at the connection. A plurality of grooves 4 are provided on the outer surface of the hose 2 at the connection. The grooves 4 are distributed in a circular array. The ring-shaped distribution of the grooves 4 can accommodate excess residual glue during gluing to prevent glue from clogging the hose 2 or the dropper 3, thereby avoiding uneven dripping in subsequent use and achieving the purpose of precise dripping. The inner side of the lower end of the drip pot 1 is provided with an overflow step 5.
[0018] In this embodiment, the overflow step 5 is H-shaped, with the upper side shorter and the lower side longer. The upper and left and right ends of the overflow step 5 protrude outward. The setting of the overflow step 5 can prevent the impact of the early droplet from falling, causing excessive flow rate and causing some unexpected situations.
[0019] In this embodiment, the lower end of the overflow step 5 is communicated with the hose 2 .
[0020] In this embodiment, the groove 4 is arranged in a vertical strip shape.
[0021] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
