Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an integrated penicillin bottle cap and a using method thereof.
Background
The clinical requirement is that the liquid medicine is in an aseptic state, and therefore, the liquid medicine needs to be contained in a sealed container. The penicillin bottle is a widely used sealed container for containing liquid medicine and can be used for containing liquid or powder medicines. Penicillin bottles, small bottles sealed by rubber plugs, are brown, transparent and the like, and are generally made of glass materials. The neck of the penicillin bottle is thin, the thickness below the bottleneck is consistent, the bottleneck is slightly thicker than the bottleneck and slightly thinner than the bottle body, and the penicillin bottle is generally used as a medicinal injection bottle, an oral liquid bottle and the like. The common rubber plug is sealed, and finally, the aluminum cap is tightly rolled by using a capping device, so that the sealing purpose is achieved. In the process of extracting the liquid medicine in the penicillin bottle by using the syringe, no air enters the closed container to fill the space for extracting the liquid medicine when the liquid medicine is extracted, so negative pressure can be generated, and clinical medical care personnel can extract the liquid medicine by using great strength. The process of extracting the liquid medicine can not protect the medicine hygiene and is easy to cause nosocomial infection. Sepsis is defined as a life-threatening organ dysfunction caused by the body's dysregulation of the response to infection and is a major cause of death in critically ill patients. Aseptic operation by medical personnel is particularly important for patients with disorders of the autoimmune system such as sepsis, organ transplantation and the like. In operations of liver, kidney and the like, the blood flow blockage inevitably leads to ischemia reperfusion injury, the blood flow blockage time directly influences the success or failure of the operations, and medical care personnel need to be matched efficiently. However, the process of extracting the liquid medicine is not only delayed, but also easily causes hand fatigue, is not beneficial to subsequent clinical and nursing operations, and is particularly not beneficial to rescue of patients when the disease condition of the patients changes suddenly and needs to compete for seconds. These inconveniences are particularly troublesome for anesthesiologists who need to draw large quantities of medicine on a daily basis and handle many perioperative flare symptoms.
Therefore, how to safely and efficiently extract the liquid medicine from the penicillin bottle is a problem to be solved by those skilled in the art.

Preferably, the diameter of the circular plastic frame is smaller than that of the plastic sawtooth cylinder periphery, and the circular plastic frame and the teeth can move downwards on the inner surface of the plastic sawtooth cylinder periphery under the action of external force.
Preferably, four horizontal plastic support columns are fixed on the circular plastic frame in a cross shape.
Preferably, the teeth formed by extending the horizontal plastic pillars below the circular plastic frame are extended outwards by 90 degrees.
Preferably, the teeth cling to the inner surface of the plastic sawtooth cylinder periphery, and can slide downwards in a one-way mode along the sawtooth-shaped lines on the inner surface of the plastic sawtooth cylinder periphery under the action of external force.
Preferably, the inner diameter of the cap needle is larger than the outer diameter of the syringe needle, and the syringe needle can penetrate into the cap needle to form a state that the needle is sleeved with the needle.
The working principle is as follows: when the liquid medicine is sucked, the aluminum cap is firstly uncovered, then the penicillin bottle body and the syringe needle cylinder are respectively held by two hands, the syringe needle is perpendicularly inserted into the small rubber plug, downward force is continuously exerted, the syringe needle is sleeved into the cap needle to form a state that the needle is sleeved with the needle, then the syringe needle pierces the sealing rubber plug to enter the penicillin bottle body, at the moment, the circular plastic frame is pressed downwards, four teeth slide downwards in a one-way mode along sawtooth-shaped lines surrounded by the plastic sawtooth cylinder, meanwhile, the cap needle pierces the sealing rubber plug to enter the penicillin bottle body, air penetrates through the air purification film, and enters the penicillin bottle body through the air chamber and a gap between the syringe needle and the cap needle.
Contrast prior art, the inside and outside pressure of balanced bottle of above-mentioned design, extract liquid medicine labour saving and time saving and health again, and then reduced the degree of difficulty of extracting the liquid medicine from xiLin bottle, solved clinical medical personnel's puzzlement.
