Abstract
The utility model discloses a venous indwelling needle. A filter 4 is arranged on the transfusion pipe 3 which is arranged between a syringe interface 1 and an indwelling needle 2. A filtration membrane 5 is arranged in the filter 4. This device has the function of filtering. The rubber particle, the glass fiber, and the insoluble medicine particle can be filtered outside the body during the intravenous transfusion; thereby the utility model reduces the harm to patients.
Description
Technical field
This utility model relates to a kind of medical transfusion utensil, particularly a kind of venous detaining needle.
Background technology
Often need the intravenous injection medicinal liquid in the clinical transfusion process, some medicinal liquid such as ampicillin, ceftriaxone sodium etc., contain a large amount of rubber particles, glass fibre and insoluble drug particle in the medicinal liquid, existing venous detaining needle lacks defecator, direct socket syringe in the time of need quietly pushing away medicine, a large amount of rubber particles, glass fibre and insoluble drug particle just enter human vas with medicinal liquid, bring harm to patient.
Summary of the invention
The purpose of this utility model is to provide a kind of venous detaining needle with filtering function.
This utility model is achieved in that a kind of venous detaining needle, comprises tube for transfusion, keeps somewhere syringe needle and syringe interface, on the tube for transfusion between syringe interface and the indwelling syringe needle filter is set, and filter membrane is set in the filter.
This utility model is provided with filter on tube for transfusion, quiet when pushing away medicine, rubber particle, glass fibre and insoluble drug particle can be filled into externally, has reduced the harm to patient.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Fig. 1 is this utility model sketch map.
Fig. 2 is the amplification view of this utility model filter part.
The specific embodiment
As shown in the figure, this utility model comprises tube for transfusion 3, keeps somewhere syringe needle 2 and syringe interface 1, on the tube for transfusion 3 between syringe interface 1 and the indwelling syringe needle 2 filter 4 is set, and filter membrane 5 is set in the filter 4.The small filtering holes of distribution on the filter membrane 5, pore size is at 0.1～0.2 μ m.By filter 4 is set, the utlity model has filtering function, compared with prior art, more can guarantee patient's transfusion safety.
