Description

nasopharyngeal anesthesia spray bottle

technical field

The invention relates to a medical device, in particular to a nasopharyngeal anesthesia spray bottle.

Background technique

Existing nasopharyngeal anesthesia watering can as shown in Figure 1. After determining the amount of anesthetic, the doctor draws the corresponding amount through the syringe and injects it into the watering can; then, connects the right end of the nozzle part to the oxygen source, and when the oxygen is ejected from the left end of the nozzle part, the downward extension of the nozzle part is inserted into the pot body A suction tube inside the unit draws the anesthetic fluid into the nozzle unit, where it is blown into the patient's throat along with oxygen.

In the case where the anesthetic is a powder that needs to be diluted with saline, the syringe needs to draw the saline and pour it into the vial containing the powder, then the powder is completely dissolved before being drawn into the syringe, and then the solution is transferred through the syringe to the watering can . Syringes are used multiple times throughout the process, and spray cans need to be opened and recapped, increasing the risk of drug contamination. Moreover, the anesthetic agent is transferred through the syringe, and the amount drawn in by the syringe is not exactly equal to the amount that the syringe pushes into the watering can, so that the amount of anesthetic agent caused by the transfer causes an error.

Detailed ways

Below, the anesthesia watering can of the present invention will be described in detail in conjunction with the accompanying drawings.

The anesthesia watering pot of the present invention includes a nozzle part 10 and a pot body part 20 .

A cover 11 is formed on the lower end of the spray head part 10, and the lower end of the suction pipe 13 extends downward from the cover, and the lower end of the suction pipe 13 is flush with each other. The upper part of the suction pipe 13 is formed with a stopper 12 for limiting the distance of the upward movement of the straw 13 , the diameter of the stopper 12 is greater than the diameter of the spout 26 ; the stopper 12 is located directly below the spout 26 .

The pot body part 20 is formed as a cylinder body 21; a spout 26 is formed on the upper end of the cylinder body 21 for combining with the lid body 11; the lid body 11 and the spout 26 are slidably combined to form a seal. A cylindrical manifold 22 is formed on the side of the cylinder 21 for installing the piston member 30; an external thread is formed on the outer periphery of the manifold 22; a raised portion 25 formed of rubber is formed on the lower side of the bottom surface 24 of the cylinder 21; The raised part 25 is used for detachably installing the needle part 40 . The bottom surface of the barrel 21 is formed with a slope 23 that slopes downward from the outer circumference to the center, so that the anesthetic fluid can be gathered around the straw more effectively, so that more anesthetic fluid can be effectively used. The cylinder body 21 is formed to be transparent, and a metering scale is formed on the cylinder body, so as to facilitate observation of the amount of anesthetic agent. A bottom circumference 27 extending beyond the raised portion 25 is also formed at the lower end of the cylinder body 21 . The bottom wall 27 can conveniently place the cylinder body 21 .

The piston member 30 includes a cylindrical piston cover 31 with one end closed, and the inner circumference of the cylindrical piston cover 31 is formed with internal threads to engage with the external threads of the manifold; the piston head 32 is formed in the middle of the cylindrical piston cover 31 The piston head 32 is inserted into the manifold 22 sealingly; the closed end of the piston head 32 and the cylindrical piston cover 31 is connected by a connecting rod 33 . The connecting rod 33 has a smaller diameter than the piston head 32 .

The needle part 40 includes a seat body 42 and a needle body, the needle body passes through the seat body 42, the upper end 41 of the needle body is located above the seat body, and the lower end 43 of the needle body is located below the seat body; the upper end 41 of the needle body is used to pass through the seat body. The protrusion 25 enters the cylinder body 21 so that the needle body communicates with the cylinder body; The lower end of the suction pipe 13 corresponds to the central position of the bottom surface of the cylinder body 21 ; the protrusion 25 is located at an eccentric position of the bottom surface 24 of the cylinder body 21 .

When in the state of pumping medicine, the lower end of the suction pipe 13 abuts against the bottom surface 24 of the cylinder body 21 to form a seal; when in the state of spraying medicine, the lower end of the suction pipe 13 is separated from the bottom surface 24 of the cylinder body by a predetermined distance by operating the cover 11 to move upwards . When taking medicine, the piston head 32 is moved by rotating the cylindrical piston cover 31 so as to take medicine.

In the structure of the present invention, the outer circumference of the piston member and the inner circumference of the manifold form a seal. In the state of pumping medicine, the suction pipe is not connected to the cylinder body, and the cylinder body is only connected to the needle part; in the state of spraying medicine, the needle part is removed, and the inside of the cylinder body is only connected to the suction pipe. The suction pipe can be in contact with the center of the barrel, and the upper end of the needle part should be misplaced with the lower end of the suction pipe, and be in an eccentric position, that is, the needle part cannot communicate with the suction pipe. The cover of the present invention is different from the cover of the prior art in that the cover of the present invention needs to move up and down, thereby forming the contact and separation of the straw and the bottom surface.

When in the state of pumping medicine, first make the cover slide down sealingly along the spout until the lower end of the straw abuts against the bottom surface of the cylinder and forms a seal between the bottom surface and the straw; then rotate the cylindrical piston cover, due to the straw It is sealed with the bottom surface of the cylinder, so the anesthetic liquid enters the cylinder through the upper end of the needle body, of course, at this time, the lower end of the needle body is inserted into the liquid medicine; the operator reads the pump through the scale on the cylinder. When the inhaled amount reaches the prescribed amount of anesthesia, stop the suction and take off the needle part, the raised part made of rubber restores and closes the hole pierced by the needle part. Slide the cover upwards so that the lower end of the straw is a predetermined distance away from the bottom surface of the cylinder. At this time, the straw communicates with the cylinder. When the oxygen source blows through the nozzle part, the anesthetic in the straw is blown out into the throat of the patient to complete anesthesia.

The invention cleverly arranges the piston in the watering can, combines the syringe and the watering can into one, avoids the pollution and dose loss caused by the transfer of liquid medicine, and provides a guarantee for accurate and safe administration of anesthetics.
