Background technology
In recent years, multiple advantages such as disposable transfusion device is simple and convenient, aseptic, nontoxic with it, no heat source response are generally used in clinical care.The present disposable transfusion device that uses, the liquid medicine filter operated by rotary motion is below a kettle, medicinal liquid enters liquid medicine filter by dripping kettle, because filtering material itself has certain thickness in the liquid medicine filter, and constitute by many slight gap, continuous immersion with liquid, gas in the gap is displaced gradually, form the periphery that the minute bubbles collection is stored in filter, the part minute bubbles are gathered into bigger bubble, and with the change of fluid pressure fluctuation, the part bubble enters human body with the liquid of infusion, even during the transfusion front exhaust the meticulous bullet of filter is beaten, the minute bubbles that collection is deposited in the filter also are difficult for complete emptying, cause invisible psychological burden to the patient, part patient even require to pull out faller gill gas by force and puncture again, thereby suspect nursing staff's operating technology and nursing quality, influence and reduced therapeutic effect.
Summary of the invention
The purpose of this utility model provides simple and easy to do, simple in structure, the easy to use safe disposable transfusion device of a kind of bleeding.
For achieving the above object, this utility model has adopted following technical scheme:. disposable transfusion device, it comprises and connects a bottle plug, transfusion catheter, drip kettle, actuator, liquid medicine filter, needle stand, described connecing between bottle plug lower end and described kettle is provided with a threeway, the described kettle port of export links to each other with described needle stand by described transfusion catheter, described actuator is set on the tube for transfusion between described kettle and the described needle stand, it is characterized in that: described liquid medicine filter entrance point is connected with described threeway lower end, and the described liquid medicine filter port of export is connected with described kettle upper end.
Above-mentioned disposable transfusion device, its characteristics are: described liquid medicine filter middle part outer rim and described kettle upper portion side wall are socketed into one.
Above-mentioned disposable transfusion device, its characteristics are: described liquid medicine filter is connected with described kettle by transfusion catheter.
Above-mentioned disposable transfusion device, its characteristics are: described liquid medicine filter is connected as a single entity by transfusion catheter and described threeway.
Above-mentioned disposable transfusion device, its characteristics are: the lower port of described threeway directly is set on the upper port of described liquid medicine filter.
Above-mentioned disposable transfusion device, its characteristics are: described liquid medicine filter top is provided with a dosing injection port that has a block.
Above-mentioned disposable transfusion device, its characteristics are: described dosing injection port has a curved arc degree.
Above-mentioned disposable transfusion device, its characteristics are: the opening end in described threeway is provided with a block.
Above-mentioned disposable transfusion device, its characteristics are: be provided with a spade tip between described transfusion catheter and the described needle stand.
Above-mentioned disposable transfusion device, its characteristics are: described spade tip is the butterfly joint.
Operation principle of the present utility model is: the liquid medicine filter position is located at is dripped in the kettle more than the liquid level, the minute bubbles that accumulate can enter by the liquid medicine filter port of export and drip kettle, dripping kettle top has part to be used to observe the space of liquid droping speed, be generally and drip kettle volumetrical 1/3, these gases only can overflow can not enter into to this space and enter human body with liquid below the liquid level, simultaneously, enter the minimum gas that drips kettle and also can not cause the obvious decline of dripping the kettle liquid level, liquid level still remains on proper level.Make the nursing staff when transfusion, needn't carry out repeatedly bullet to filter and beat, bleeding is more convenient, and is safer, time saving and energy saving, increases work efficiency.
The beneficial effects of the utility model are:
1. eliminated the phenomenon of gas intravasation, the patient producing the nervous feared state of mind, has not increased the trust to the nursing staff, and harmonious nurse-patient relationship has improved nursing quality.Helping the patient feels at ease to receive treatment.
2. aesthetic in appearance, succinct, production technology and cost are compared with the traditional infusion device and are changed not quite, are convenient to producer and directly put into production, needn't carry out invest in the transformation of real estate to equipment.The structure of threeway, the two one of liquid medicine filter is simplified manufacturing process flow, has improved production efficient, saves cost.
3. according to mechanics principle, increase lifting surface area pressure is reduced, the sword-shaped needle needle stand pulled out and connects when the butterfly joint of catheter of transfusion system lower end was beneficial to the intravenous injection operation, was easy to nursing staff's operation.This joint internal diameter even thickness, inner wall smooth avoid gas to adhere to, and the observation when selecting for use transparent plastic material to be convenient to the nursing staff patient is infused.
This utility model has kept all functions of former transfusion device, filter is to infusion bottle and go into the kettle medicinal liquid and played filtration, filters locations setting and have the drip velocity of apart from length various concentration liquids being gone into kettle operation, bleeding, liquid between the threeway of dosing injection port and have no effect is played positive impetus to the research and development of products of producer and to the raising of clinical nursing activity quality.
