Abstract
The utility model belongs to the improvement of a suckling mouse lavage needle structure in a medical experiment, in particular to a nested type suckling mouse lavage device. The nested type suckling mouse lavage device comprises a needle handle which is in cooperation with a needle pipe. A rubber plug is arranged on the head portion of the needle handle. A needle head is installed on an outlet of the needle pipe. A flexible pipe device with the flexible pipe is installed on the needle head. The structure of the flexible pipe device is a connecting sleeve arranged at one end of the flexible pipe. The connecting sleeve is installed on a needle head seat in a sleeved mode. The nested type suckling mouse lavage device is reasonable in structure. Damage to a suckling mouse oral cavity and an esophagus is small when the suckling mouse is lavaged. Success rate of the suckling mouse lavage can be improved.
Description
Technical field
This utility model belongs to the improvement of medical experiment to neonatal rat gavage needle construction, particularly a kind of nested type neonatal rat irrigation stomach device.
Background technology
Domestic neonatal rat gavage pin commonly used is stainless steel neonatal rat gavage pin at present, quality is hard, neonatal rat oral cavity, esophagus very easily stab in use procedure, cause the gavage failure, those of skill in the art use rustless steel gavage pin to carry out the gavage success rate and do not reach 50%, cause the waste of personnel, reagent, time, fund, severe jamming the experiment process.Owing to there is no suitable neonatal rat gavage equipment, domestic to utilize neonatal rat gavage technology to carry out correlational study less, especially in researchs such as some biotoxin detections, pathogenesis, affects greatly.
Summary of the invention
The purpose of this utility model is to provide a kind of nested type neonatal rat irrigation stomach device, and its mechanism is reasonable, while giving the neonatal rat gavage, little to neonatal rat oral cavity, esophagus infringement, can improve the success rate of neonatal rat gavage.
The purpose of this utility model is achieved in that a kind of nested type neonatal rat irrigation stomach device, comprise the needle handle matched with needle tubing, the needle handle head is provided with rubber stopper, in the outlet of needle tubing, syringe needle is installed, hose arrangement with flexible pipe is installed on syringe needle, the end that the structure of hose arrangement is flexible pipe is arranging adapter sleeve, and adapter sleeve is sleeved on needle holder.
The hose arrangement that the utlity model has flexible pipe is nested on syringe needle, and syringe needle is nested on syringe.During use, syringe is pushed away to handle, and to shift bottom onto emptying air, and flexible pipe section inserts below gavage medicament liquid level, pulls syringe to push away handle, and the suction medicament, observe the scale corresponding with pushing away the handle piston position, determines the gavage pharmaceutical quantities.With forefinger and thumb fixedly the neonatal rat head mouth is opened, flexible pipe section is carefully inserted to esophagus, go deep into stomach downwards, pushing syringe pushes away handle medicament is injected to the neonatal rat gastric, extracts gently, the neonatal rat gavage completes.Because flexible pipe is very soft, use separately flexible pipe to be difficult to insert gastric, use separately the rustless steel syringe needle, can produce wound to neonatal rat oral cavity, esophagus, even the gavage success, but neonatal rat can be very fast dead.Flexible pipe is nested on syringe needle, needle length is about 2cm, and flexible pipe grows the about 0.5cm of syringe needle, the rustless steel syringe needle plays a supportive role to flexible pipe, can guarantee that flexible pipe enters esophagus smoothly, and soft flexible pipe can not cause damage to esophagus, guaranteed the success of gavage, also guaranteed the unlikely damage of neonatal rat organ.Simultaneously, the scale on syringe, can accurately show gavage dosage.Through us, try to use, nested type neonatal rat irrigation stomach device can be increased to neonatal rat gavage success rate more than 90% by 50%, has solved the current domestic problem depositing aspect the neonatal rat gavage, has practical value preferably.
This utility model mechanism is reasonable, while giving the neonatal rat gavage, little to neonatal rat oral cavity, esophagus infringement, has improved the success rate of neonatal rat gavage.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described, Fig. 1 is this utility model structural representation, the A-A sectional structure schematic diagram that Fig. 2 is Fig. 1.
The specific embodiment
A kind of nested type neonatal rat irrigation stomach device, as shown in Figure 1 and Figure 2.Comprise the needle handle 5 matched with needle tubing 4, needle handle 5 heads are provided with rubber stopper 3, and syringe needle 2 is installed in the outlet of needle tubing 4, and the hose arrangement with flexible pipe 1 is installed on syringe needle 2, the end that the structure of hose arrangement is flexible pipe 1 is arranging adapter sleeve 6, and adapter sleeve 6 is sleeved on needle holder.The flexible pipe outer end grows the needle point 0.4-0.6cm of syringe needle.The external diameter of flexible pipe is 0.8-1mm.Scale evenly is being set on needle tubing.
