Abstract
A two-way venoclysis needle is provided, which comprises a needle head and a silica gel tube. The silica gel tube is connected with the needle head with one end and is attached with an interface at the other end. The utility model is characterized in that: the silica gel tube is opened with a side tube to push liquid medicine and the side tube is attached with a rubber cap. During normal transfusion, the utility model, if liquid medicine is required for temporary, is able to add the liquid medicine from the side tube mentioned without need to open the infusion set again, which is capable of pushing medicine repeatedly without affecting the normal transfusion and therapy. Besides, the rubber cap is available to be punctured repeatedly, thus making the utility model possess good self-closing performance after pulling out the needle head and avoiding the side tube communicated with the outside. The utility model is suitable for patients with transfusion applicable to a plurality of channels as well, so as to prevent puncturing at several places to damage blood vessel.
Description
Technical field
This utility model belongs to medical apparatus, particularly a kind of venoclysis needle.
Background technology
The venoclysis needle of clinical practice is made up of silica gel tube and syringe needle, and silica gel tube one end connects syringe needle, and the other end has interface and is connected with the other parts (drainage screen end) of disposable transfusion device.In patient's normal infusion process, due to illness people's change of illness state is fast, the often interim rescue medicine of using.Under existence conditions, the joining place that often unplugs transfusion device (drainage screen end) and transfusion needle (or claiming scalp acupuncture) pushes away medicine.The problem of its existence is to influence normal infusion; Unplug easily repeatedly and pollute; In the process that unplugs, enter by bubble unavoidably.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of two general formula venoclysis needles, has suffered dosing repeatedly and has not influenced normal infusion in infusion process.
This utility model two general formula venoclysis needles comprise syringe needle, silica gel tube, and silica gel tube one end connects syringe needle, and the other end has interface, it is characterized in that offering on the described silica gel tube one and pushes away the medicine side pipe, pushes away the medicine side pipe and has rubber cap.
In the normal infusion process, as the interim dosing of need, can add from pushing away the medicine side pipe, need not to unplug again transfusion device.But the rubber cap repeated localised puncture, extract syringe needle after dereism good, avoid pushing away the medicine side pipe and communicate with the external world.
Advantage of the present utility model:
In infusion process, medicine be can push away repeatedly, normal infusion and treatment do not influenced.Also be applicable to the multichannel transfusion patient, avoid the many places puncture to cause blood vessel injury.Consume material is few, and is cheap.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 interface, 2 rubber caps 3 push away medicine side pipe 4 silica gel tubes 5 syringe needles
The specific embodiment
As Fig. 1, two general formula venoclysis needles comprise syringe needle 5, silica gel tube 4, and silica gel tube 4 one ends connect syringe needle 5, and the other end has interface 1 and is connected with the drainage screen end of transfusion device, offers on the silica gel tube 4 and pushes away medicine side pipe 3, pushes away medicine side pipe 3 and has rubber cap 2.The effect of rubber cap 2 is that sealing pushes away medicine side pipe and the puncture that is used for syringe needle, can adopt to be enclosed within the mode that pushes away medicine side pipe outside or to be the rubber plug structure mode.
In the normal infusion process, as the interim dosing of need, add from pushing away medicine side pipe 3, need not to unplug again transfusion device.
