Description

Hermetically sealed infusion set

Technical field

This utility model relates to a kind of medical apparatus, specifically a kind of hermetically sealed infusion set.

Background technology

Existing infusion set is to be mixed with the normal saline of medicine or Glucose Liquid etc. with the vial splendid attire, is communicated with the syringe needle that inserts human body by tube for transfusion, and medicinal liquid is imported human body.Existing infusion set is the constancy of volume of vial in use, and after liquid flowed out certain amount, pressure of the inside of a bottle will reduce like this, and medicinal liquid just no longer flows out under the negative pressure in bottle.For preventing the generation of above-mentioned phenomenon, the air inlet pipe of can on infusion bottle, pegging graft usually, to be connected with the outer atmosphere of bottle, the pressure that equilibration flask is inside and outside guarantees that medicinal liquid can circulate smoothly.Mostly be connected to defecator on the air inlet pipe of Shi Yonging now, but airborne microorganism, pathogenic bacteria and harmful chemical can enter in the infusion bottle still, cause the pollution of bottle inner liquid medicine, even may cause nosocomial infection by air inlet pipe, harm patient's health.Above-mentioned infusion set also is connected to the kettle that drips that expands at the middle part of tube for transfusion, so that can control the speed of dripping of medicinal liquid at any time.But drip the medicinal liquid that the interior gas of kettle is understood the contaminated stream warp equally, form potential safety hazard.In order to stop the generation of above-mentioned pollution medicine source situation, Chinese patent CN2194730Y discloses a kind of totally enclosed type infusion set, and it adopts flexible material to make transfusion bag, by tube for transfusion the medicinal liquid in the bag is imported human body.This infusion set is a flexibility of utilizing transfusion bag, need not under the situation of air inlet pipe, relies on atmospheric external pressure compressing transfusion bag, successfully medicinal liquid is imported human body, has stopped the situation of outside atmosphere by air inlet pipe pollution medicinal liquid.But, for observing the fast situation of dripping of transfusion, the setting of dripping kettle must be arranged also on the tube for transfusion of this infusion set, therefore still have the possibility of gaseous contamination medicinal liquid, still can't accomplish.

The utility model content

The purpose of this utility model just provides a kind of hermetically sealed infusion set of realizing transfusion under the complete air-proof condition, takes place to avoid the contaminated situation of medicinal liquid, improves the safety of transfusion.

This utility model is achieved in that hermetically sealed infusion set includes tube for transfusion and transfusion bag, its design main points are that this device also includes the liquid water bottle, the liquid water bottle is divided into upper cavity and lower chamber, on upper cavity, be provided with water filling port, on lower chamber, be provided with bottom, transfusion bag is contained in the lower chamber, and the infusion port of transfusion bag passes the sealable opening on the bottom.Be connected to the communicating pipe that is communicated with upper and lower cavity on the bottle wall of liquid water bottle, a kettle is dripped in communicating pipe middle part connection.Before the use, earlier transfusion bag is put into the liquid water bottle after, seal after in the upper and lower cavity of liquid water bottle, filling with water respectively by water filling port and bottom again.During use, along with continuously outflowing of transfusion bag inner liquid medicine, under the condition that water filling port opens wide, the intravital water of epicoele will with the shared spatial volume of filling output medicinal liquid, keep the continuous of transfusion along the continuous lower chamber that flows into of communicating pipe.Be contained in the kettle that drips at communicating pipe middle part like this by observation, can grasp the speed of dripping of transfusion exactly.

This utility model can make no longer to be provided with on the tube for transfusion that joins with infusion vessel and drip kettle, thereby has realized the transfusion of sealing fully, has thoroughly avoided the pollution of air to medicinal liquid.

The bottle that this utility model is preferably in the liquid water bottle is connected to the exhaustor that communicates with lower chamber on the wall, connects the bypass pipe of upper and lower cavity on the bottle wall of liquid water bottle, and valve all is set on bypass pipe and exhaustor.Like this under the situation of not opening liquid water bottle bottom, open the valve on bypass pipe and the exhaustor, can once the upper and lower cavity of liquid water bottle be filled with water by the water filling port on the liquid water bottle upper cavity, thereby simplify operating process to the upper and lower cavity water filling of liquid water bottle.

The bottom lower ending opening of the infusion port of the transfusion bag in this utility model and liquid water bottle can be by being located at transfusion bag the sealing member sealing at infusion port place, also can adopt other known mode to realize sealing.

The infusion port internal fixation that this utility model is preferably in transfusion bag has sealed cover slip, to guarantee the sealing of transfusion bag in transportation, preservation and use.

This infusion set utilizes the gravity of medicinal liquid and the flexibility of transfusion bag to realize medicinal liquid input human body under the situation of not establishing air inlet pipe, has avoided extraneous gas to enter infusion set by air inlet pipe and has polluted medicinal liquid, makes medicinal liquid in use safer.This device utilizes the kettle on communicating pipe can accurately grasp transfusion speed, need not on tube for transfusion, connect again and drip kettle, thereby be sealed in medicinal liquid in this infusion set completely, stopped the possibility that medicinal liquid contacts with polluter, make the input human body medicinal liquid more pure, safer when patient uses.
