Description

A medicine spraying device for otolaryngology

technical field

The utility model belongs to the technical field of medical equipment, in particular to an otolaryngology medicine spraying device.

Background technique

Anesthetics refer to drugs that can cause temporary and reversible loss of sensation and pain in the entire body or parts of the body. Proper use of anesthetics during surgery can effectively relieve the patient's pain and make the operation go smoothly. In most cases, anesthesia is used by injection, but some operations require patients to take oral anesthesia to achieve the effect of anesthesia. In order to avoid the anesthetic drug coming into contact with the tongue, the traditional oral method is that the patient throws the drug down the throat and drinks a lot of water quickly to make the drug enter the body. The medication process needs to be very fast, and there are certain risks, which cannot be realized for some patients with limited mobility.

Utility model content

The purpose of this utility model is to provide an ENT medicine spraying device, which is used to solve the problem that the existing way of taking anesthetics in the ENT department has a high risk and cannot be realized for some patients with limited mobility.

For realizing above-mentioned technical purpose, the technical scheme that the utility model adopts is as follows:

A spraying device for otolaryngology, comprising a rubber ball, the left end of the rubber ball is provided with a water inlet pipe, the water inlet pipe is provided with a water inlet check valve, the right end of the rubber ball is provided with a water outlet pipe, and the water outlet pipe The right end is provided with a medicine storage ball, the upper end of the medicine storage ball is provided with a medicine feeding pipe, the medicine feeding pipe is provided with a medicine feeding check valve, the right end of the medicine storage ball is connected with a catheter, and the head of the right end of the catheter gradually The right end of the outer wall of the catheter is provided with a plurality of blocks in the circumferential direction, and the right end of the catheter is covered with a rubber sleeve. The rubber sleeve is a cylindrical structure with an open left end and a closed right end. The left part of the rubber sleeve The outer wall is provided with a card hole matching the card block, and the middle part of the side wall of the rubber sleeve is radially provided with a drug outlet groove.

The utility model adopting the above-mentioned technical scheme, when in use, through the cooperation of the clamping block and the clamping hole, the rubber sleeve is set on the conduit from the right end of the conduit, and then injects clean water into the rubber ball from the water inlet pipe through the syringe equipped with clean water, and then Connect the drug inlet tube through the syringe containing the anesthetic drug, inject the anesthetic drug into the drug storage ball, then remove the two syringes, extend the catheter from the patient's mouth into the patient's throat, squeeze the rubber ball, and make the rubber ball The clear water inside enters the drug storage ball through the outlet pipe, and then sprays from the small hole at the right end of the catheter into the rubber sleeve, so that the anesthetic in the drug storage ball enters the patient's throat under the push of clean water; A large amount of water is sprayed from the small hole, and in order to ensure that the anesthetic will not flow out of the small hole when the rubber ball is not squeezed, it must be ensured that the diameter of the small hole cannot be too large. When the water sprayed out from the small hole, it will cause a huge impact on the throat of the patient. The function of the rubber sleeve is to block the water sprayed from the small hole, so that the water sprayed from the small hole will be blocked by the rubber sleeve first, and the speed will be reduced. After that, it will flow out from the medicine outlet tank to avoid discomfort to the human body caused by too fast water flow. With such a structural design, the anesthetic is directly delivered to the throat of the patient through the catheter, which reduces the risk of taking the medicine. For some patients with limited mobility, the medicine can also be successfully completed under the operation of the medical staff.

It is further defined that the outer wall of the right part of the conduit is provided with an annular retaining ring at the left end of the block, and the annular retaining ring is integrally formed with the conduit. With such a structural design, after the rubber sheath is set on the right end of the catheter, the position of the rubber sheath inserted into the catheter will not be too deep, resulting in misalignment of the clamping block and the clamping hole, affecting the stability of the clamping connection.

Further defined, the water outlet pipe is provided with a water outlet one-way valve. Such a structural design can prevent the anesthetic from entering the rubber ball, because the water in the rubber ball may not be used up during use, that is, it will completely enter the patient's throat. If the anesthetic enters the rubber ball, it will inevitably cause the anesthetic Insufficient dosage; at the same time, it can also prevent the rubber ball from being sucked back into the device from the catheter to cause pollution when the rubber ball is squeezed and deformed to recover.

It is further defined that the right end of the rubber sleeve is a round head structure. With such a structural design, when inserted into the patient's throat, the patient's comfort is higher than other structures.

It is further defined that the catheter is detachably connected to the medicine storage ball. With such a structural design, since the catheter will extend into the patient's mouth and throat during use, it will inevitably carry a large amount of saliva, sputum and other liquids in the patient's mouth after use, while other rubber balls and medicine storage balls are not contaminated. If these things are cleaned together, it is a waste of cleaning resources; however, the detachable connection allows the conduit to be removed and cleaned separately, saving resources and making cleaning more convenient.

Further defined, there are more than three blocks. Such a structural design can enhance the stability of the connection between the catheter and the rubber sleeve, and is more practical.
