Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a throat sprayer. Background Art

[0002] Internal medicine is a comprehensive subject in clinical medicine. It covers a wide range of areas and has a strong integrity. It studies the causes, diagnosis, prevention and treatment of diseases of various systems and organs of the human body. It includes throat examination, indirect laryngoscopy, and laryngeal tumor resection surgery under fiber laryngoscope. Before the operation, the patient's throat must be anesthetized using an anesthetic sprayer inserted into the patient's mouth before the operation can be performed.

[0003] When using the current laryngeal sprayer, it is difficult for the anesthetic agent in the spray tank to be fully mixed with other auxiliary agents (physiological saline), resulting in a decrease in the anesthetic effect, making it impossible for the patient to enter the anesthesia state, and the pain caused by the patient leads to a decrease in the success rate of the operation, thereby reducing the utilization efficiency of the sprayer. Therefore, in order to solve this problem, the utility model proposes a laryngeal sprayer. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Reference Figure 1-Figure 5 A throat sprayer comprises a cup body 1, a rotating block 2 is detachable from the top of the cup body 1, a mounting cavity 3 is arranged inside the rotating block 2, a rotating liquid guide tube 4 is vertically arranged inside the mounting cavity 3 and inside the cup body 1, a stirring blade 5 located inside the cup body 1 is arranged on the surface of the liquid guide tube 4, and a spray piece 6 installed on the rotating block 2 is connected to the top of the liquid guide tube 4.

[0024] In the utility model, first, the anesthetic agent and other auxiliary agents (physiological saline) are introduced into the cup body 1 from the top port of the cup body 1, and then the stirring blade 5 designed on the catheter tube 4 on the rotating block 2 is put into the cup body 1 from the top port of the cup body 1 and rotated to lock, and the drive part 9 of the servo motor is started by the switch designed on the surface of the rotating block 2 to drive the circular gear 1 10, the circular gear 2 11 and the catheter tube 4 to rotate relative to each other, so that the stirring blade 5 designed on the surface of the catheter tube 4 can stir and mix the anesthetic agent and other auxiliary agents introduced into the cup body 1, thereby ensuring that the anesthetic agent and other auxiliary agents can be fully mixed, finally, the nozzle on the liquid outlet tube 62 is introduced into the patient's oral cavity, and the infusion pump 61 is started, so that the catheter tube 4 can mix the sufficient drugs in the cup body 1, and spray anesthesia to the patient's oral cavity through the nozzle of the liquid outlet tube 62. In addition, in the present technical scheme, there are related ones that are not mentioned in detail, all of which belong to the prior art.

[0025] Reference Figure 2 The cup body 1 and the rotating block 2 are threaded disassembly structures. When the cup body 1 and the rotating block 2 are threaded disassembly structures, the inner wall of the cup body 1 corresponding to the top port is provided with an internal thread 7, and the bottom of the rotating block 2 is fixed with an external threaded connecting ring 8 threadedly connected to the internal thread 7.

[0026] In the utility model, the design of the internal thread 7 and the external thread connecting ring 8 is to enable the rotating block 2 and the top port of the cup body 1 to have a disassembly feature. With this design, there is no need to design a medicine inlet structure on the top of the cup body 1. At the same time, it is also helpful to remove the stirring blade 5 on the surface of the catheter 4 from the cup body 1, which is convenient for subsequent cleaning.

[0027] Reference Figure 1 A gap space is reserved between the bottom end of the liquid guiding tube 4 and the inner bottom wall of the cup body 1 .

[0028] In the present invention, a certain gap space is reserved between the bottom end of the liquid guide tube 4 and the bottom wall of the cup body 1, which helps the liquid guide tube 4 to introduce the mixed medicine inside the cup body 1 into the liquid outlet tube 62 under the action of the infusion pump 61 to perform spray anesthesia into the patient's mouth.

[0029] Reference Figure 1-Figure 2 , the diameter of the stirring blade 5 is smaller than the diameter corresponding to the top port of the cup body 1.

[0030] In the utility model, the diameter of the stirring blade 5 is smaller than the corresponding diameter of the top port of the cup body 1. This design helps the stirring blade 5 to smoothly enter or escape from the top port of the cup body 1, making it convenient to subsequently remove the stirring blade 5 from the inside of the cup body 1 for cleaning.

[0031] Reference Figure 3-Figure 4 A driving unit 9 is installed on the inner bottom wall of the mounting cavity 3, and an output end of the driving unit 9 is connected to a circular gear 10 attached to the bottom of the rotating block 2, and a circular gear 2 11 which is matched and fixed on the catheter 4 is connected to the surface of the circular gear 10.

[0032] In the present invention, the design of the driving part 9, the circular gear 1 10 and the circular gear 2 11 is to cooperate with the catheter 4 to drive the stirring blade 5 to fully mix the medicine introduced into the cup body 1, thereby improving the anesthetic effect of the medicine.

[0033] Reference Figure 1 The sprayer 6 includes an infusion pump 61 mounted on the rotating block 2. The bottom of the infusion pump 61 is connected to the top of the catheter 4 through a bearing. The top of the infusion pump 61 is connected to a liquid outlet pipe 62 with a nozzle, and the liquid outlet pipe 62 is a hose structure.

[0034] In the present invention, the spray element 6 is designed to facilitate the extraction of the liquid inside the cup body 1 and introduce it into the patient's oral cavity for spray anesthesia. The spray element 6 is mainly a prior art and will not be described in detail here.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
