technical field

The invention relates to a drug delivery device during anesthesia, in particular to a drug delivery device for automatic treatment of bronchospasm under general anesthesia.

Background technique

Respiratory spasm generally refers to the sharp contraction of the smooth muscles of the larynx, trachea, bronchi, bronchioles, and terminal bronchi, resulting in narrowing of the lumen and airway obstruction. The main reason is that the mucous membrane of the respiratory tract is too sensitive. When encountering allergens or temperature changes, it will cause respiratory spasm, which mostly occurs in young children and those with allergic constitution.

During some major surgeries, anesthesia mixed with oxygen is sent into the patient's body through the trachea to maintain the operation.

During surgery, patients sometimes experience airway spasms that block the airway and prevent anesthesia from entering the body. At this time, the doctor needs to urgently inject or spray anti-spasmodic drugs into the patient.

However, the above-mentioned processes all need to be manually operated, and there is no device that can automatically administer drugs during general anesthesia.

The above-mentioned drug delivery device for the automatic treatment of bronchospasm under general anesthesia of the present invention is characterized in that: in the drug bottle, there is an atomized anti-spasm drug with a certain pressure, and the drug is budesonide aerosol or Terbutaline aerosol.

The above-mentioned drug delivery device for the automatic treatment of bronchospasm under general anesthesia of the present invention is characterized in that the piston area of the cylinder is 6-10 times the area of the cylinder tube.

The above-mentioned drug delivery device for general anesthesia and automatic treatment of bronchospasm of the present invention is characterized in that: the drug guiding tube is also provided with a switch.

The method of using the device of the present invention is as follows: during operation, the drug bottle is filled with nebulized medicine for treating convulsions, inserting one end of the drug guiding tube into the drug bottle, and turning on the switch. Fix the end of the spiral tube at the patient's throat, turn on the anesthesia machine, and the mixed gas of anesthetic and oxygen is sent into the patient's body.

Under normal circumstances, under the pressure of the spring, the through hole at the upper end of the cylinder shaft is located below the drug guide tube, that is, the through hole does not communicate with the drug guide tube, and the medicine cannot enter the threaded tube through the drug guide tube.

When the patient has respiratory spasm, the trachea of the human body contracts, the mixed gas cannot enter the body, the pressure in the threaded tube increases, and the pressure in the cylinder also increases. When the force of the cylinder shaft is greater than the force of the spring, the cylinder piston and cylinder are pushed The shaft moves, so that the through hole on the cylinder shaft communicates with the drug guide tube, and the aerosol in the medicine bottle enters the threaded tube through the drug guide tube, and then enters the human body, quickly eliminating or relieving the patient's airway spasm. When the patient no longer has convulsions, the pressure in the threaded tube drops rapidly. When the force of the cylinder shaft is less than the force of the spring, the cylinder shaft retracts to its original position, and the through hole on the cylinder shaft is no longer connected with the drug guide tube. Block the drug guide tube.

The piston area of the cylinder is larger than the area of the cylinder tube, and the pressure of the cylinder piston can be increased under the same pressure, which is beneficial to promote the movement of the cylinder shaft.

The present invention selects nebulizable drugs such as budesonide, and when the drugs are mixed with mixed gas (oxygen and anesthetic), they enter the body to quickly relieve the spasm reaction without affecting the operation.

The beneficial effect of the present invention is that, during operation, when airway spasm occurs, medicine can be automatically given to the patient to quickly eliminate or alleviate the patient's spasm, so that the operation can be carried out smoothly and the patient is prevented from suffocating.
