Abstract
The utility model discloses a disposable venous retention needle with a liquid medicine filtering membrane, which is an improvement on the basis of the original disposable venous retention needle; thedisposable venous retention needle mainly comprises a guide tube seat, and a liquid filling port arranged on the guide tube seat for carrying out filling to a clinical patient in the bolus injectionprocess; the disposable venous retention needle is characterized in that: a liquid medicine filtering membrane is arranged in the liquid filling port; in the bolus injection process of the clinical patient, the bolus injection medicine can be filtered by the special liquid medicine filtering membrane, so as to effectively reduce and prevent infusion particles from entering in a patient body and eliminate medical accidents caused by the infusion particles; the disposable venous retention needle has simple structure, convenient operation, safety and reliability and low production cost, and can be widely applied to medical and clinical treatment.
Description
One, technical field
This utility model relates to a kind of venous detaining needle that medical field is used for the clinical patient aspect that belongs to, particularly Gai Liang disposable vein remaining needle.
Two, background technology
At present, the existing venous detaining needle that is used for the clinical patient aspect all is not provided with liquid medicine filtering membrane on structure, to such an extent as in clinical patient being carried out the quiet process that pushes away medicine, inevitably transfusion particle is input in patient's body simultaneously, this is unfavorable for patient's treatment and rehabilitation, and also can exists the hidden danger of malpractice and malpractice takes place easily.
Three, utility model content
The purpose of this utility model is the venous detaining needle that a kind of improvement will be provided, particularly be with liquid medicine filtering membrane disposable vein remaining needle, be used for the venous detaining needle of clinical patient aspect because of liquid medicine filtering membrane is not set to solve to have now at present, in clinical patient being carried out the quiet process that pushes away medicine, simultaneously transfusion particle is input into unavoidably in patient's body and is easy to generate unexpected drawback.
The purpose of this utility model is achieved in that this utility model band liquid medicine filtering membrane disposable vein remaining needle improves on the basis of original disposable use venous detaining needle, it mainly comprises catheter block, and be used on the catheter block clinical patient it is characterized in that: in described filling opening, be provided with liquid medicine filtering membrane making the quiet filling opening that the medicine process is carried out liquid feeding that pushes away.
The disposable use of this utility model, clinical patient is being carried out quiet pushing away aspect the medicine, because its distinctive liquid medicine filtering membrane can filter the quiet medicine that pushes away, can reduce and stop transfusion particle to enter in patient's body effectively, thereby avoid and stopped so and the malpractice of generation.It is simple in structure, and is easy to operate, safe and reliable, and production cost is low, can be widely used in the medical treatment clinical in.
Four, description of drawings
Fig. 1, be according to the structural representation that the utility model proposes.
Five, the specific embodiment
Below in conjunction with drawings and Examples structure of the present utility model is further described:
Labelling among the figure: 1, catheter block; 2, filling opening; 3, liquid medicine filtering membrane.
In the drawings, this utility model band liquid medicine filtering membrane disposable vein remaining needle is improved on the basis of original disposable use venous detaining needle, it mainly comprises catheter block 1, and be used on the catheter block 1 clinical patient is being made the quiet filling opening 2 that the medicine process is carried out liquid feeding that pushes away, it is characterized in that: in described filling opening 2, be provided with liquid medicine filtering membrane 3.
By distinctive liquid medicine filtering membrane 3 in this utility model, in clinical patient being carried out the quiet process that pushes away medicine, can filter the quiet medicine that pushes away, this just can reduce and stop transfusion particle to enter in patient's body effectively, thereby avoids and stopped therefore and the malpractice that takes place.
Above-described only is preferential embodiment of the present utility model.Should be pointed out that to those skilled in the art under the prerequisite that does not break away from this utility model principle, can also make some modification and improvement, this also is considered as belonging to protection domain of the present utility model.
