Description

Nasopharyngeal anesthesia device

Technical Field

The utility model mainly relates to the medical field, in particular to a nasopharyngeal surface anesthesia device.

Background Art

During clinical anesthesia induction, if there is gastrointestinal obstruction, pathological requirements, facial damage or a pregnant woman, the patient must be allowed to maintain spontaneous breathing and intubated while awake.

In order to reduce the patient's pain, it is required to give the patient's nasopharynx and glottis sufficient surface anesthesia before tracheal intubation.

During general anesthesia, long cotton swabs or cotton gauze strips soaked in local anesthetic solution are often used to anesthetize the nasal mucosa. The anesthesia effect and range are not perfect, and there are also great requirements for the operators.

In addition, inhalation of nebulized local anesthetics is also used clinically to obtain surface anesthesia of the airway (including the nasal cavity and nasopharynx). This requires the patient to be able or willing to cooperate in deep breathing, but the intensity of anesthesia obtained in the airway is uncertain.

Summary of the invention

In view of the above-mentioned defects of the prior art, the utility model provides a nasopharyngeal topical anesthesia device, comprising an injection tube and a flat anesthesia hose, wherein the injection tube and the anesthesia hose are connected via a connector;

A medicine cavity is provided inside the anesthesia hose and is connected to the injection tube through a connecting piece. A plurality of medicine spraying holes are provided at equal intervals on the side wall of the anesthesia hose.

Preferably, the connecting piece includes a mouth opener in the middle section, a locking ring for fixing the mouth opener and the injection tube, and a connecting flat tube for connecting the anesthesia hose. The side wall of the mouth opener is provided with a supporting surface for preventing the connecting piece from entering the human oral cavity. The two ends are respectively provided with a slotted threaded opening and a connecting flat tube. The locking ring is connected to the slotted threaded opening through a thread.

Preferably, the inner cavity of the slotted threaded opening is wide at a section away from the opening support device and narrow at the other end.

Preferably, the side wall of the connecting flat tube is provided with an anti-falling groove.

Preferably, an anti-falling protrusion is provided on the inner side wall of one end of the anesthesia hose connecting connector.

Preferably, the radius of the spray hole increases gradually from an end away from the connecting piece to an end close to the connecting piece.

Preferably, scale values are set on the surface of the injection tube.

Beneficial effects of the utility model:

1. Directly penetrate into the human body through the anesthesia hose, directly inject and spray the medicine through the syringe, and the spraying operation can be carried out evenly;

2. The depth of medication is controlled by medical staff, and even if a certain amount of pressure is applied, it is not easy to damage the patient's rhinitis membrane;

3. The dosage of the medicine is controlled and there will be no overdose of anesthesia.

DETAILED DESCRIPTION

In order to make the technical solution of the present invention better understood by the technical personnel in the field, and to make the above-mentioned features, purposes and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with the embodiments. The embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

As shown in Fig. 1-2, the utility model includes: an injection tube 1 and a flat anesthesia hose 2, wherein the injection tube 1 and the anesthesia hose 2 are connected via a connector 3;

The anesthesia hose 2 has a medicine cavity therein connected to the injection tube 1 through a connector 3 , and the side wall of the anesthesia hose 2 has a plurality of medicine spray holes 21 equidistantly formed therein.

First, inject enough anesthetic liquid into the injection tube 1, connect the injection tube 1 and the anesthesia hose 2 through the connecting piece 3, and insert the anesthesia hose 2 into the nasal cavity. When it is about to reach the nasopharynx, push the injection tube 1 to push the liquid medicine out from the spray hole 21 by pressure, and then gradually withdraw the anesthesia hose 2 into the patient's body, and simultaneously push the injection tube 1 to continuously administer the medicine.

After the injection tube 1, the anesthesia hose 2 and the connector 3 are connected, a portion of the liquid medicine will flow into the anesthesia hose 2 and the connector 3, but it will not affect the implementation of the device.

In order to achieve a better anesthesia effect, the radius of the spray hole 21 gradually increases from the end away from the connector 3 to the end close to the connector 3. This ensures that when spraying, the amount of liquid sprayed at the front section is greater than the amount of liquid sprayed at the rear section, and the excess liquid remains in the patient's body to prevent excessive anesthesia. At the same time, the spray hole 21 at the rear section mainly prevents the occurrence of inadequate anesthesia.

In order to better control the amount of medicine, scale values are set on the surface of the injection tube 1.

As the specific structure of the connecting member 3:

The connector 3 includes a mouth opener 31 in the middle section, a locking ring 32 for fixing the mouth opener 31 and the injection tube 1, and a connecting flat tube 33 for connecting the anesthesia hose 2. The side wall of the mouth opener 31 is provided with a supporting surface 311 for preventing the connector 3 from entering the human oral cavity, and both ends are respectively provided with a slotted threaded opening and a connecting flat tube 33, and the locking ring 32 is connected to the slotted threaded opening through a thread.

The inner cavity of the slotted threaded opening is wide at a section away from the opening supporter and narrow at the other end.

The side wall of the connecting flat tube 33 is provided with an anti-falling groove.

An anti-falling protrusion is provided on the inner side wall of one end of the anesthesia hose 2 connected to the connecting piece 3.

When the medicine outlet of the injection tube 1 is connected to the slotted threaded port, the locking ring 32 can be rotated to play the role of a fixing belt. The inner wall of the slotted threaded port can prevent the sealing ring from forming a sealing ring to complete the sealing.

When the anesthesia hose 2 is put on the connecting flat tube 33, the anti-drop-off protrusion is embedded in the anti-drop-off groove to complete the sealing and fixing.

The above embodiments are merely illustrative of the principles and effects of this patent application, and are not intended to limit this patent application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of this patent application. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in this patent application should still be covered by the claims of this patent application.
