Abstract
The utility model relates to a medicine liquid dropping type catheter which comprises a syringe needle, a needle hole formed in the syringe needle, a three-way device and a side sliding hole arranged at one side of the syringe needle. An outlet end I and an outlet end II are arranged at the top end of the three-way device, a fixing tube is inserted in to the outlet end II in a sealed mode, the lower end of a sliding tube is inserted into the side sliding hole in a sliding mode, the upper end of the sliding tube is inserted in the fixing tube in a sliding mode, the bottom of the three-way device is fixed with the top end of the syringe needle in a sealed mode, a urine discharge hole inside the outlet end I is communicated with the syringe needle, and a guide wire is arranged in the fixing tube. When the syringe needle is pulled out, the sliding tube is pushed outwards through the guide wire till the sliding tube stretches out of the side sliding hole, then the syringe needle with antibiotics is taken out and is inserted into the tube opening position of the fixing tube, after the syringe needle is pulled out, due to the fact that the sliding tube is still in a body, a needle tube is pushed at the moment to enable medicine liquid is injected into the wound after passing through the fixing tube and the sliding tube, antiinflammation is achieved, and finally the sliding tube is taken out completely. By means of the medicine liquid dropping type catheter, the phenomenon of the fester of the wound caused by being subjected to bacterial infection is avoided effectively.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of catheter.
Background technology
As everyone knows, in Urology Surgery, need to use catheter to insert urethra or intravesical for some bladder diseases, urine is directly drawn out to external, but the long-term catheter that inserts easily makes site of puncture infected by antibacterial, thereby cause wound suppuration.
Summary of the invention
This utility model, in order to overcome the deficiency of above technology, provides a kind of medicine catheter that can propel to wound site medicinal liquid.
This utility model overcomes the technical scheme that its technical problem adopts:
This medicine catheter, comprise syringe needle, be arranged at pin hole, the three-way device on syringe needle and be arranged at the sideslip hole of syringe needle one side, described three-way device top is respectively arranged with port of export I and port of export II, one stationary pipes sealing is plugged in port of export II, slide and be plugged in sideslip hole in sliding tube lower end, and slide and be plugged in stationary pipes in its upper end, described three-way device bottom is fixing with needle tip sealing, urine tap and the pin hole conducting of described port of export I inside, be provided with seal wire in described stationary pipes.
In order to improve sealing, also comprise plug, on described plug, be provided with groove, on the inwall of described stationary pipes top, be provided with barb, described plug is fastened on the barb in stationary pipes by groove.
The beneficial effects of the utility model are: while needing urethral catheterization, syringe needle is inserted in patient body, urine can flow in three-way device through pin hole afterwards, and the urine tap in the port of export I of three-way device is discharged.In the time that needs are extracted syringe needle, first by seal wire, sliding tube is outwards promoted until it stretches out from sideslip hole, afterwards extraction there is is antibiotic needle tubing to be inserted into the mouth of pipe place of stationary pipes, extracting after syringe needle, due to sliding tube also in vivo, therefore now promote needle tubing, make medicinal liquid spurt into wound after stationary pipes and sliding tube, realize antiinflammation, finally completely sliding tube is taken out, effectively prevented that wound is infected by antibacterial and causes the phenomenon of suppurating to occur.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plug portion structure schematic diagram;
In figure, 1. syringe needle 2. three-way device 3. port of export I4. port of export II5. stationary pipes 6. sliding tube 7. sideslip hole 8. pin hole 9. urine tap 10. seal wire 11. plugs.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, accompanying drawing 2, this utility model is described further.
As shown in Figure 1, this medicine catheter, comprise syringe needle 1, be arranged at pin hole 8, the three-way device 2 on syringe needle 1 and be arranged at the sideslip hole 7 of syringe needle 1 one sides, three-way device 2 tops are respectively arranged with port of export I3 and port of export II4, one stationary pipes 5 sealings are plugged in port of export II4, slide and be plugged in sideslip hole 7 in sliding tube 6 lower ends, and slide and be plugged in stationary pipes 5 in its upper end, three-way device 2 bottoms and syringe needle 1 end sealing are fixed, urine tap 9 and pin hole 8 conductings of port of export I3 inside, be provided with seal wire 10 in stationary pipes 5.While needing urethral catheterization, syringe needle 1 is inserted in patient body, urine can flow in three-way device 2 through pin hole 8 afterwards, and the urine tap 9 in the port of export I3 of three-way device 2 is discharged, and therefore urinal is inserted in urine tap 9 by plastic tube.In the time that needs are extracted syringe needle 1, first by seal wire 10, sliding tube 6 is outwards promoted until it stretches out from sideslip hole 7, afterwards extraction there is is antibiotic needle tubing to be inserted into the mouth of pipe place of stationary pipes 5, extracting after syringe needle 1, due to sliding tube 6 also in vivo, therefore now promote needle tubing, make medicinal liquid spurt into wound after stationary pipes 5 and sliding tube 6, realize antiinflammation, finally completely sliding tube 6 is taken out, effectively prevented that wound is infected by antibacterial and causes the phenomenon of suppurating to occur.
As shown in Figure 2, can also comprise plug 11, on plug 11, be provided with groove, on stationary pipes 5 top inwalls, be provided with barb, plug 11 is fastened on the barb in stationary pipes 5 by groove.In the time of urethral catheterization at ordinary times, plug 11 can be blocked to the mouth of pipe of stationary pipes 5, prevent that urine from flowing out from stationary pipes 5.In the time of needs liquid medicine injection, then plug 11 is taken off and inserts needle tubing.The convenience and the safety that use are improved.
