Description
Technical field
The utility model relates to clinical care technical fields, specifically, being a kind of detachable intravenous injection filter device.
Background technique
Vein treatment one of most important administration route when being clinical treatment, rescue, medical fluid is directly inputted blood by it, hair
Raw efficacy time is short, and effect is rapid.
In the nursing of clinical treatment at present when vein treatment inputs drug, insoluble drugs particle, rubber particle in medical fluid
Or glass chip etc. enters blood of human body therewith, and it is documented that: the diameter of electricity consumption sem observation these glass chips, rubber particle
There was only 10um in the diameter of 10-30um, and the capillary of human body, so these invisible particles, which will be deposited on lungs, to be caused
Decline in pulmonary function, at present decline in pulmonary function in a large amount of crowds, lung capacity is low has some relations with this, so clinic has paid attention to this
One problem, research and development contain accurate filter infusion apparatus, and ultimate filter uses the filter medium less than 5um, can be effectively
Insoluble particle in medical fluid is filtered out, to reduce damage of the particle to human body.
The shortcoming of the method is: the treatment of intravenous injection in clinic is after having aspirated medical fluid with syringe, will be defeated
Liquid pipe is separated with scalp syringe needle hole, then connect medicine injection with scalp acupuncture with syringe nipple, due to medical fluid in injection process
It is not directly entered blood by filter, then insoluble drugs particle, rubber particle or glass chip etc. in medical fluid
Human health is endangered therewith blood of human body is entered.
With the increasingly specification of vein treatment, has partial clinical nurse and find disadvantage present in intravenous injection therapeutic process
The advantages of end, has developed " the filter bulb formula scalp acupuncture " of filter ball Yu scalp acupuncture one, this needle can prevent medical fluid in syringe
Particle enters in vivo, but the method is also clearly present not foot point:
1. if the device unitary design cannot take off leave and take the chemical examination of patient's blood specimen by scalp acupuncture before intravenous injection
Filter ball is unloaded, blood will affect result of laboratory test by filtering ball device.
If just having blood in filter ball 2. blood back occurs in infusion process in patient and being detained and influence transfusion speed,
Increase the risk of infusion reaction.
Clinically nurse additionally uses to prevent drug microparticles from entering human body through Murphy type burette upper end external connector
Injection of medicine removes particle by the filter device of infusion apparatus.
Shortcomings of this method is that: the high nurse operation in Murphy type burette position is inconvenient, if drug in infusion strap and pushed away
Injection object has incompatibility, and crystallization is easy to appear in infusion apparatus and causes to block and occur adverse reaction.
Chinese patent literature CN201520891105.0, applying date 2015.11.10, patent name are as follows: a kind of intravenous

Mutually cooperation；Also, medicine-carrying trough is provided on the support unit.
A kind of intravenous filter device of above patent document is linked together simultaneously using support unit and filter element
Cage structure is formed, support unit rear and front end is respectively equipped with front end, tail end internal screw thread tube seat, filter element rear and front end difference
It equipped with front end, rear end male-pipe, is cooperated using front end riffled tube and front end male-pipe, tail end riffled tube is with after
Male-pipe is held to cooperate, the medicine-carrying trough for recycling support unit to be equipped with filters to reach the intravenous filter for installation
Thrombus effect is good, histocompatbility is good, easy to operate, the recyclable and vena cave mistake that can extend Implantation Time, delay endothelialization
Filter, the effect having important practical significance with good application prospect.But about a kind of low in cost, small in size, use
Simplicity can effectively remove the various particles in intravenous injection medical fluid, reduce the hazard factor in vein medical treatment, reduce vein
Injection is injured caused by patient health, reduces patient economy burden, and the one kind for improving intravenous injection treatment safety coefficient can take off
Intravenous injection filter device is unloaded then without relevant report.
In conclusion need it is a kind of it is low in cost, small in size, using simplicity, can effectively remove intravenous injection medical fluid
In various particles, reduce vein medical treatment in hazard factor, reduce intravenous injection injured caused by patient health, reduce suffer from
Person's financial burden improves a kind of detachable intravenous injection filter device of intravenous injection treatment safety coefficient.
