Description

Technical Field

[0001] The utility model relates to the technical field of microemulsion drug administration, in particular to a microemulsion drug spray head. Background Art

[0002] Microemulsion spray nozzle is a device or apparatus for spraying or spraying microemulsion. Microemulsion is a micellar system composed of oil phase and water phase, with small particle size and high stability, and has broad application prospects in drug delivery and application.

[0003] Compared with conventional nozzles, microemulsion nozzles have the following differences: microemulsion nozzles can more accurately control the injection volume and spray range of the drug solution, as well as parameters such as injection speed and flow rate. This precise control helps to achieve personalized and accurate drug delivery in drug treatment; because microemulsion nozzles can produce fine droplet sizes, they can improve the injection efficiency of drugs. Smaller droplet sizes are conducive to the uniform distribution of drugs in local areas, improving drug absorption and utilization efficiency; microemulsion nozzles can help maintain the stability of microemulsion drugs and reduce the decomposition and inactivation of drugs during injection. Microemulsion drugs usually have a long shelf life and can maintain the stability of their chemical and physical properties before injection; microemulsion nozzles are usually used for local drug delivery, such as skin, eyes, nasal cavity, etc. They can be widely used in the fields of skin disease treatment, ophthalmic medication, nasal administration, etc. In short, compared with conventional nozzles, microemulsion nozzles have higher accuracy, efficiency and stability in drug delivery, can meet some specific drug delivery needs, and have broad application prospects in related fields.

[0004] However, when administering the drug, the conventional microemulsion drug nozzle needs to extract the drug liquid by pressing, so as to spray the drug. However, in order to adapt to the microemulsion drug, the microemulsion drug nozzles currently used mostly use a thin film channel to spray the drug. In this process, the drug liquid is pressed against the film under the action of an external force. When the pressure on the film reaches a critical point, the drug passes through the thin film channel to form droplets and sprays out. In this process, the operator needs to press repeatedly continuously, and it is difficult to ensure that the force of each press is consistent, resulting in uneven flow during the drug liquid spraying process, and may even cause the drug liquid spraying to be interrupted or the drug liquid to overflow. At the same time, due to the need for continuous and repeated pressing, the operator may feel hand fatigue, especially when performing a large number of spraying operations. This not only affects the comfort of the operation, but also may reduce the accuracy and stability of the operation. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model is operated by an operator with only one hand, which is simpler than repeated pressing operation. The operator only needs to squeeze the air bag in advance to pump air into the medicine bottle body to increase pressure, and then the ball valve body can be rotated in the subsequent operation to realize the spraying and administration of the medicine liquid, avoiding the problem of intermittent spraying of the medicine during repeated pressing operation. At the same time, under the action of high pressure, the microemulsion medicine can be discharged quickly and stably through the thin film channel on the diaphragm body, thereby improving the stability and uniformity of the spraying. Since the spraying and administration of the medicine liquid are realized by controlling the valve stem of the ball valve body The flow rate and injection volume of the medicine liquid can be better controlled, and the overflow and waste of the medicine liquid can be reduced. The operator can directly hold the inverted medicine bottle body, and thus accurately position the medicine liquid to the patient's medication position through the connecting tube, making the medication operation more precise and controllable, and improving the safety and comfort of the user. In short, the utility model places the diaphragm body in the positioning shell, and combines the design of the positioning shell, the ball valve body and the sealing cover to achieve a simpler, continuous and stable microemulsion medicine injection and medication operation, while reducing the waste of medicine liquid and improving the user's operating convenience and safety.
