Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to single use venoclysis needle.
Background technology
Venous transfusion is that hospital clinical gives emergency treatment to a patient and one of important measures treating patient, the most the most frequently used disposable venous infusion needle is to use to be socketed in tubular needle tube for transfusion, being punctured by syringe needle to patient's blood vessel during use, medicine passes through tube for transfusion and transfusion needle intravasation.In infusion process, adding medicine, the method used at present is the most temporarily, separates nipple and the scalp acupuncture junction of transfusion device, after adding medicine, then the two is connected, such inconvenient operation, and junction is easily contaminated, and is susceptible to infusion reaction.Further, due to separating for several times, joint is easy to fall off, causes the phenomenon of leakage, it is impossible to ensure patient safety treatment.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of easy to use, decrease the single use venoclysis needle of pollution.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is, single use venoclysis needle, including flexible pipe, one end of described flexible pipe connects needle stand, and described needle stand is for being connected with transfusion device, the other end of described flexible pipe connects syringe needle, being provided with a feed tube on described flexible pipe and near one end of needle stand, described feed tube is connected with inside hose, and described feed tube is additionally provided with a dismountable sealing device；On described flexible pipe, and it is provided with, at feed tube, the control piece preventing liquid countercurrent.
Further, in this feed tube, and within one week, it is provided with filter membrane around its inwall.
Further, this sealing device is the block that lid is located at feed tube end, and is provided with screw thread on described block inwall.
Further, this control piece is the clip being arranged at outside flexible pipe.
Further, this control piece is for being arranged at flexible pipe internal check valve, so that medicinal liquid is towards the direction one-way flow of syringe needle.
Further, this syringe needle is arranged with protection pipe.
Further, it is connected by hard pipe between this syringe needle with flexible pipe, described hard pipe is provided with needle handle.
This utility model single use venoclysis needle has the advantage that 1. is easy to operate, during use, it is only necessary to closes transfusion regulation valve, opens block and can add medicinal liquid.2. it is difficult to be contaminated.3. it is provided with filter membrane in feed tube, quiet is not susceptible to venous transfusion reaction when pushing away medicinal liquid.4. on flexible pipe, clip is set, quiet push away medicinal liquid before and after be difficult to occur in blood back and anti-hemostatic tube enter air, it is possible to ensure the safety of patient.5. block only need to screw, and would not fall off and the phenomenon of leakage.The most in emergency situations, it is possible to make the medicinal liquid pushed quickly arrive in the patient.

Detailed description of the invention
This utility model single use venoclysis needle, as depicted in figs. 1 and 2, including flexible pipe 6, one end of described flexible pipe 6 connects needle stand 1, described needle stand 1 is for being connected with transfusion device, and the other end of flexible pipe 6 connects syringe needle 4, is provided with a feed tube 2 on described flexible pipe and near one end of needle stand 1, feed tube 2 is internal with flexible pipe 6 to be connected, and feed tube 2 is additionally provided with a dismountable sealing device；On flexible pipe 6, and it is provided with, at feed tube 2, the control piece preventing liquid countercurrent.In feed tube 2, and within one week, it is provided with filter membrane 8 around its inwall.During actual production, determine the position of filter membrane 8 according to the length of feed tube 2, if feed tube 2 is comparatively short, filter membrane 8 can be arranged at the junction of feed tube 2 and flexible pipe 6, in case in infusion process during dosing, the nipple of syringe touches filter membrane 8.
Single use venoclysis needle of the present utility model, sealing device is the block 3 that lid is located at feed tube 2 end, and is provided with screw thread on block 3 inwall.During dosing, it is only necessary to close clip 9 and turn on block 3, after dosing terminates, block 3 of screwing on, open clip 9 and be not susceptible to pollute.
Single use venoclysis needle of the present utility model, a kind of embodiment is, as it is shown in figure 1, control piece is the clip 9 being arranged at outside flexible pipe 6.By stepping up of clip 9, quiet push away medicinal liquid before and after be difficult to occur blood back and anti-hemostatic tube enter air
Single use venoclysis needle of the present utility model, another embodiment is, as in figure 2 it is shown, control piece is the check valve 10 being arranged in flexible pipe 6, so that medicinal liquid is towards the direction one-way flow of syringe needle 4.Quiet push away medicinal liquid before and after be difficult to occur in blood back and anti-hemostatic tube enter air.
Single use venoclysis needle of the present utility model, syringe needle 4 is arranged with protection pipe 5.It is connected by hard pipe between syringe needle 4 with flexible pipe 6, hard pipe is provided with needle handle 7.
This utility model single use venoclysis needle, during use, is connected transfusion device with the needle stand 1 of this single use venoclysis needle, when needing to add medicinal liquid during transfusion, the regulation valve on close transfusion device, when using clip 9, steps up clip 9；When using check valve 10, directly open spiral block 3, the nipple end making syringe is connected with feed tube 2, get final product injection liquid, after injecting, close clip 9, the nipple end of syringe is separated with feed tube 2, screw block 3, open transfusion device regulation valve after opening clip 9, carry out normal venous transfusion.
Single use venoclysis needle in this utility model, convenient use, solve in existing infusion process, when need to add medicinal liquid, use the problem that remaining needle is connected with transfusion device.Compared with remaining needle, low cost, how much a venoclysis needle has only to, and the price of remaining needle, the price 30 of single remaining needle～90 yuan, for the patient bad to economic situation, it is unwilling to select remaining needle.Further, to some patient, especially old people, blood vessel is more crisp, is not suitable for indwelling remaining needle；It addition, patient's state of an illness need not prick remaining needle, simply infuse every other day.
