Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of department of dermatologry puncture drainage needle.
Background technology
The department of dermatologry of prior art is the tip inclined-plane with the syringe needle of puncture drainage needle, and in piercing process, this puncture needle may cause the normal hypodermic damage in patient deep excessively deeply because of inserting needle.The medical worker need use syringe when patient's drain in addition, but therefore the finite capacity of syringe will be extracted syringe after folder closes drainage tube when full hydrops in the syringe is discharged taking out.This operation not only needs to repeat, and folder closes the breakage that drainage tube easily causes drainage tube.
The utility model content
The purpose of this utility model provides a kind of improved department of dermatologry puncture drainage needle, to solve the problems of the technologies described above effectively, overcomes the defective that exists in the above-mentioned prior art.
For achieving the above object, this utility model is taked following technical scheme.
A kind of department of dermatologry puncture drainage needle comprises brokenly sword-shaped needle, nook closing member and drainage system, and wherein, the syringe needle of described broken sword-shaped needle is the inclined-plane opening; Described nook closing member is hollow tubular, and its head end is that taper is blunt nosed, and described nook closing member inserts in the described broken sword-shaped needle; Described drainage system is connected with the tail end of described nook closing member.
Further, described drainage system comprises sleeve pipe, suction tube, and the tail end of described nook closing member inserts described sleeve pipe, and described suction tube is socketed on the described sleeve pipe, and the upper end of described suction tube is provided with handle, and the lower end of described suction tube is provided with discharge pipe.
Further, be provided with some side openings at described nook closing member.
The beneficial effects of the utility model are: the first, and department of dermatologry of the present utility model is blunt nosed with the nook closing member of puncture drainage needle, has avoided the normal hypodermic risk of damage in the piercing process, has alleviated medical worker's operating pressure.The second, adopt department of dermatologry puncture drainage needle of the present utility model, do not need to extract one after another syringe, do not need folder to close drainage tube yet, thereby improved the efficient of drain and avoided closing the drainage tube breakage that drainage tube causes because of folder.
Description of drawings
Fig. 1 is the structural representation that this utility model department of dermatologry is used puncture drainage needle.
Among the figure, the 1-head end, the 2-side opening, the 3-syringe needle, 4-breaks sword-shaped needle, 5-nook closing member, 6-sleeve pipe, 7-suction tube, 8-handle, 9-discharge pipe.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
Department of dermatologry of the present utility model comprises brokenly sword-shaped needle 4, nook closing member 5 and drainage system with puncture drainage needle as shown in Figure 1, and the syringe needle 3 of broken sword-shaped needle 4 is the inclined-plane opening; Nook closing member 5 is hollow tubular, and its head end 1 is blunt nosed for taper, and nook closing member 5 inserts in the broken sword-shaped needle 4; Drainage system is connected with the tail end of nook closing member 5.Drainage system comprises sleeve pipe 6, suction tube 7, and the tail end of nook closing member 5 inserts in the sleeve pipe 6, and suction tube 7 is socketed on the sleeve pipe 6, and the upper end of suction tube 7 is provided with handle 8, and the lower end of suction tube 7 is provided with discharge pipe 9.
As preferably, the close head end side of nook closing member 5 is provided with some side openings 2.
When using department of dermatologry of the present utility model to perform a surgical operation with puncture drainage needle, the syringe needle 3 of broken sword-shaped needle 4 is moved forward to the head end of nook closing member 5, make head end 5 place the back of syringe needle, extract that nook closing member is stayed is subcutaneous thereby will break sword-shaped needle behind the broken skin.Fixing nook closing member, outer handle 8 is discharged the liquid drain to suction tube and by discharge pipe.Handle 8 is advanced to the head end thruster of nook closing member 5, and outer handle 8 is proceeded drain then.
The above is preferred embodiment of the present invention only, is not to limit practical range of the present invention; If do not break away from the spirit and scope of the present invention, the present invention is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of claim of the present invention.
