Change into the internal thread with the original external screw thread of pipe shaft, so alright go out the pipe shaft with an injection mold shaping, and can guarantee that the lid does not evade in the pipe shaft, optimized the forming process who gathers the pipe, reduce the preparation cost who gathers the pipe.
Description
Technical Field
The utility model belongs to the technical field of medical treatment detects, a detection sample collecting pipe is related to.
Background
Shown in figure 1 is a fecal occult blood sample collecting tube, which comprises a cover A, a sampling rod B, a protective cover C and a tube body D, wherein the opening part of the tube body is provided with an external thread E, and the fixed connection between the cover and the tube body is realized after the internal thread of the cover is matched with the external thread of the tube body. At present, the pipe body is formed by injection blow molding, a pipe mold blank is formed by injection molding of an injection molding machine, the external thread of the pipe opening is formed at the moment, and then the pipe body is formed by heating and blow molding. The tube body is formed by an injection mold and a blow mold, and the process is complex, so that the cost of the sample collecting tube is high.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to simplify the forming process of the collecting pipe and reduce the cost of the collecting pipe.
In order to achieve the above purpose, the utility model provides a technical scheme as follows:
the detection sample collecting pipe comprises a cover, a sampling rod, a protective cover and a pipe body, wherein a section of taper hole and an inner threaded part are inwards and sequentially arranged at the pipe orifice of the pipe body, a section of taper column matched with the taper hole and an outer threaded part matched with the inner threaded part are arranged outside the cover; one end of the sampling rod is fixed in the cover, and the other end of the sampling rod is inserted into the tube body; the one end that the lid is relative the shaft is provided with the projection, be provided with out the liquid hole in the projection, the visor with the projection is connected and is stopped up go out the liquid hole.
Compared with the prior art, the utility model discloses the beneficial effect who has is: change into the internal thread with the original external screw thread of pipe shaft, so alright go out the pipe shaft with an injection mold shaping, and can guarantee that the lid does not evade in the pipe shaft, optimized the forming process who gathers the pipe, reduce the preparation cost who gathers the pipe.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.
FIG. 1 is a schematic view of a prior art collection tube;
FIG. 2 is a cross-sectional view of the test sample collection tube (with the tube body removed) in the example;
FIG. 3 is a sectional view of the tube body in the embodiment;
FIG. 4 is a cross-sectional view of a test sample collection tube in an example embodiment.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Examples
Referring to the detecting sample collecting tube shown in fig. 2-4, the detecting sample collecting tube comprises a cover 10, a sampling rod 20, a protective cover 30 and a tube body 40, wherein a section of conical hole 41 and a section of internal thread part 42 are sequentially arranged inwards at the tube mouth of the tube body, a section of conical column 11 matched with the conical hole and a section of external thread part 12 matched with the internal thread part are arranged outside the cover. One end of the sampling rod is fixed in the cover, and the other end of the sampling rod is inserted into the tube body. The taper of the taper hole and the taper column is preferably 3-5 degrees, so that the pipe body can have enough capacity. The external thread part and the conical column of the cover are inserted into the pipe orifice, the cover is screwed to enable the external thread part to be meshed with the internal thread part, and the conical column is contacted with the conical surface of the conical hole along with the screwing of the cover until the conical column is in interference fit with the conical surface of the conical hole to form sealing at the pipe orifice.
The original external screw thread of pipe shaft is changed into the internal thread to this embodiment, so alright go out the pipe shaft with an injection mold shaping, and can guarantee that the lid does not evade in the pipe shaft, has optimized the forming process who gathers the pipe, reduces the preparation cost who gathers the pipe.
One end of the cover opposite to the tube body is provided with a convex column 13, a liquid outlet hole 14 is arranged in the convex column, and the protective cover is connected with the convex column and blocks the liquid outlet hole. The sample collecting tube is internally pre-stored with a dissolving solution, the stool sample scraped by the sampling rod is dissolved in the dissolving solution, the protective cover is unscrewed, and the dissolving solution mixed with the sample drips out from the liquid outlet hole.
Further, an external thread part I15 is arranged outside the convex column, and an internal thread part I matched with the external thread part I is arranged inside the protective cover; the convex column is internally provided with a plug 31 inserted into the liquid outlet hole to prevent the collecting pipe from leaking liquid.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
Claims (5)
