Abstract
The utility model discloses a stomach irrigation needle, which comprises a catheter. A base capable of being connected with external infusion equipment is arranged at one end of the catheter; a needle head is arranged at the other end of the catheter; at least one liquid outlet hole is arranged on the outer wall of the needle head; the needle head and the catheter are in an integral structure, namely the tail end of the catheter is the needle head; the needle head at the tail end of the catheter is in a structure with a closed top end; and the base, the catheter and the needle head are made of high molecular materials. The stomach irrigation needle is capable of allowing the catheter to be conveniently inserted into a digestive tract of an experimental animal without injuring a stomach wall of the experimental animal, and simultaneously effectively prevents the stomach wall from blocking a liquid outlet of the needle head. In addition, the stomach irrigation needle is simple in structure, convenient in manufacturing and easy in popularization and utilization.
Description
Technical field
This utility model relates to and a kind ofly is intended to laboratory animal is irritated a kind of filling stomach instrument of excess of the stomach when testing, and is specifically related to a kind of filling stomach pin.
Background technology
Known, at present, it all is to be made by metal material that the employed laboratory animal of each scientific research institution and universities and colleges is irritated the stomach pin.The metal base that the essential structure of described filling stomach pin is divided into the metal needle of falling the droplet-shaped, metal catheter and is connected with syringe.Wherein, the experimental clinical requirement of metal catheter of some product has been designed to certain radian, to adapt to the digestive tract structure of laboratory animal.With pedestal and suck in advance after experiment is connected with the syringe of liquid, left hand is caught the laboratory animal collare, and the right hand slowly inserts the digestive tract of syringe needle along animal, until desired depth, and the perfusion fluid be scheduled to of injection experiments then.
But, many times because metal material is really up to the mark, perhaps because operator's error, cause the intensive uncomfortable reaction of laboratory animal, even, cause the coat of the stomach damage of laboratory animal because degree of depth assurance is inaccurate, to the effectiveness and the verity generation adverse influence of experimental result.In addition, the situation that the coat of the stomach that also often occurs laboratory animal in practical operation stops up the liquid outlet of needle tip, so, experiment becomes very unhappy with the input of liquid, causes the input quantity that the experimenter can not liquid with precise control.
The utility model content
For overcoming deficiency of the prior art, the purpose of this utility model is to provide a kind of filling stomach pin, this filling stomach pin can insert catheter in the digestive tract of laboratory animal easily, and can effectively not avoid coat of the stomach to stop up the phenomenon of syringe needle liquid outlet simultaneously its coat of the stomach damage.
For solving the problems of the technologies described above, reach above-mentioned technique effect, this utility model has adopted following technical scheme:
A kind of filling stomach pin comprises a conduit, and described conduit one end is a pedestal that can be connected with outside infusion apparatus, and the other end of described conduit is a syringe needle, has the liquid outlet of at least one on the outer wall of described syringe needle.
Further, described syringe needle and described conduit are structure as a whole, and promptly the end of conduit is considered as syringe needle.
Further, the terminal needle section of described conduit is divided into the structure of a top closure formula.
Further, the material of described pedestal, conduit and syringe needle is a macromolecular material, for example polrvinyl chloride, natural rubber, polyethylene, polyamide, polypropylene, polystyrene, silicone rubber, polyester, politef, polymethyl methacrylate and polyurethane etc. and their mixture thereof.
Utilize filling stomach pin of the present utility model, when operator will irritate the stomach pin along in the process of the stomach of the digestive tract insertion laboratory animal of laboratory animal, because the pliability of macromolecular material itself, and the body temperature of animal has formed one near the gastral shape of laboratory animal to the emollescence of macromolecular material with the catheter part of irritating the stomach pin in the digestive tract of laboratory animal.
Compared with prior art, the utlity model has following beneficial effect:
Filling stomach pin of the present utility model is for metal needle, and the plastic spike that macromolecular material is made is little to the lateral pressure of digestive tract wall, thereby the comfortableness that has improved laboratory animal in the experimentation has also made things convenient for the operation of experiment operator.Simultaneously, reduced the risk that laboratory animal digestive tract wall is hurt.In addition, the liquid outlet that has on liquid outlet by the syringe needle outer wall or the conduit pours into experiment when use liquid, has effectively avoided the needle tip obstruction and situation that can not fluid.In addition, improved needle tip adopts the form of sealing, will more help irritating the insertion of stomach pin.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of description, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Fig. 1 is the structural representation that this utility model is irritated stomach pin one embodiment.
Number in the figure explanation: 1. pedestal, 2. conduit, 3. syringe needle, 201,301. liquid outlets, the formula structures of 302. sealings.
Specific implementation method
Referring to shown in Figure 1, a kind of filling stomach pin comprises a conduit 2, and described conduit 2 one ends are a pedestal 1 that can be connected with outside infusion apparatus, and the other end of described conduit 2 is a syringe needle 3, has the liquid outlet 301 of at least one on the outer wall of described syringe needle 3.
Further, described syringe needle 3 is structure as a whole with described conduit 2, and both the end of conduit 2 was considered as syringe needle 3.
Further, terminal syringe needle 3 parts of described conduit 2 are the structure 302 of a top closure formula.
Further, the material of described pedestal 1, conduit 2 and syringe needle 3 is a macromolecular material, for example polrvinyl chloride, natural rubber, polyethylene, polyamide, polypropylene, polystyrene, silicone rubber, polyester, politef, polymethyl methacrylate and polyurethane etc. and their mixture thereof.
Above-mentioned filling stomach pin of the present utility model is described in detail; for one of ordinary skill in the art; thought according to this utility model embodiment; the part that all can change in specific embodiments and applications, therefore all any changes of being made according to this utility model design philosophy are all within protection domain of the present utility model.
