Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a sprayer for administering medicine to the throat of a patient after surgery. Background Art

[0002] In clinical practice, patients with oral and maxillofacial tumors often experience edema and congestion in the throat due to the influence of endotracheal intubation under general anesthesia. To address this situation, medication needs to be administered through the throat after surgery to relieve the inflammatory response. Currently, the commonly used method is to reduce the inflammatory response through nebulized hydrocortisone, but for patients who have undergone tracheotomy, it is difficult for the nebulized method to act on the upper respiratory tract (such as the throat), so a more effective route of administration needs to be found.

[0003] A common way of drug administration is to spray the drug directly into the throat through the mouth. However, patients with oral and maxillofacial tumors have surgical wounds in their mouths after surgery, and direct contact may cause secondary injuries. Therefore, it is particularly important to design a drug delivery device that can be shaped and maintain stability. It can penetrate deep into the mouth without touching the wound, ensuring that the drug can accurately act on the affected area. At present, the existing drug delivery devices in hospitals usually use a combination of a syringe and a connecting tube. This drug delivery method is not only inconvenient to operate, but also has many inconveniences in carrying and storing syringes and drugs, which makes it difficult to meet the needs of caregivers for drug administration and patients for self-administration. In addition, the hardness of the connecting tube has also become a key issue. A connecting tube that is too hard may increase the patient's discomfort, while a connecting tube that is too soft may not guarantee the accuracy and stability of drug administration.

[0004] Therefore, in response to the above problems, we urgently need to develop a new type of bottled sprayer, which can not only meet the needs of nursing staff and patients for self-administration, but also be easy to carry and store, and can ensure that the drug acts accurately and stably on the throat, thereby effectively alleviating the inflammatory response of postoperative patients and improving the patient's rehabilitation effect and quality of life. The development of this innovative drug delivery device has important clinical significance and broad application prospects. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a sprayer for administering medicine to the throat of a patient after surgery.

[0006] The technical solution of the utility model is: a drug delivery sprayer for the throat of a patient after surgery, comprising a kettle body, a pressing pump arranged in the kettle body, a pressing head fixedly connected to the top of the pressing pump, a pressing nozzle fixedly connected to the right side of the pressing pump, a connecting piece threadedly connected to the right side of the pressing nozzle, a connecting pipe fixedly connected to the right side of the connecting piece, a spray head fixedly connected to the right side of the connecting pipe, a connecting cover fixedly connected to the outer side of the top of the pressing pump, and the connecting cover is threadedly connected to the top of the kettle body.

[0007] Furthermore, the pressing pump includes a suction tube, a cavity is fixedly connected above the suction tube, a piston is movably connected in the cavity, a piston rod is fixedly connected above the piston, a one-way ball valve is provided at the connection point between the cavity and the suction tube, a limit cover is fixedly connected above the one-way ball valve, a sleeve is provided above the piston, a sealing sleeve is movably clamped on the outside of the sleeve, the outside of the sealing sleeve is slidably connected to the inner wall of the cavity, a suction hole is provided on the side wall below the piston rod, the top of the piston rod is connected to the inside of the sleeve, and the top of the sleeve is fixedly connected to the pressing head.

[0008] Description: After the pressing head is pressed, the liquid in the cavity is squeezed and enters the pressing head, and then enters the connecting pipe. After the pressing head is released, the piston moves upward under the action of the spring, and the one-way ball valve shifts and the liquid suction tube sucks the liquid into the cavity.

[0009] Furthermore, a push cover is movably connected to the top of the kettle body, a dust cover is hinged on the right side of the push cover, a placement groove is fixedly connected to the right side wall of the kettle body, and the placement groove is movably connected to the dust cover.

[0010] Note: Bend the connecting pipe and place it in the placement slot, then cover it with a dust cover to facilitate the carrying and storage of the sprayer and prevent the connecting pipe and nozzle from being contaminated.

[0011] Furthermore, the length of the connecting pipe is 14-17 cm, and the shape of the nozzle is hemispherical.

[0012] Description: The hemispherical nozzle is easy to insert into the mouth close to the throat, and has a large spraying area and a wide range of action.

[0013] Furthermore, a metal guide wire is fixedly connected inside the connecting tube, the connecting tube is made of polyvinyl chloride, the nozzle is made of maternal and infant grade silicone material, the connecting tube has a diameter of 5-8 mm and a wall thickness of 1-2 mm.

[0014] Description: The connecting tube has a built-in metal guide wire, which can be shaped outside the mouth, making it easier to insert into the patient's wound. The nozzle is made of maternal and infant grade silicone material, which is soft in texture and reduces the risk of throat injury and postoperative wound injury to the patient.

[0015] The beneficial effects of the utility model are:

[0016] The utility model can spray the medicine accurately onto the throat wound through the cooperation of the spray pot and the connecting tube, and can effectively reduce the risk of the connecting tube being contaminated by the dust cover. The design of the dust cover is more convenient to carry, which is convenient for patients to carry and can be repeatedly used for throat medication. BRIEF DESCRIPTION OF THE DRAWINGS
