Description

[0001] Drip device for injecting linger's solution [

The present invention relates to a liquid dispensing device.

In general, patients who are unable to consume food, surgery patients, and patients who need to supply nutrients due to decreased function of the human body, are forced to administer the liquid to the patient's blood vessel through the medical liquid administration set.

The infusion set used for forcibly administering the infusion fluid as described above includes a infusion dispenser for infusing the infusion solution into the infusion bottle into which the infusion solution is injected, A hose, a syringe connected to the end of the injection hose and injected into the blood vessel of the human body, and a fluid injection amount adjuster installed at one side of the injection hose to adjust the injection amount of the fluid injected into the blood vessel.

Generally, a caregiver or a nurse checks the amount of Ringer's solution while the patient is receiving the fluid, and replaces it with a new fluid container if the fluid in the fluid container is exhausted.

However, if the caregiver or the nurse can not recognize when the fluid container is to be replaced, air may enter the blood vessel after the fluid is completely filled, or the blood of the patient may flow backward through the syringe and the injection hose.

Therefore, careful attention and care of the caregiver were required to check the dose and the dosage of the sap from time to time in order to observe the amount and amount of the sap, and when the sap remains constant, the nurse had to pull the sap container beforehand and replace it.
