Description
Technical field
This utility model relates to a kind of teaching experimental tool, is specifically related to a kind of Physiological Experiment frog metal probe.
Background technology
For the student of pharmaceutical specialty, by probe, laboratory animal is carried out various Physiological Experiment (such as: medullotherapy
Experiment etc.) it is the education activities that it is frequently necessary to carry out, but owing to present student is pampered and spoiled at home, few people exist
Family uses needlework, receives sole even without meeting family old man, so majority does not knows how to take pin, in education experiment mistake
Journey will exist a lot of trouble, the when of at school, need teacher to emphasize many times over, demonstrate many times over, but student is the most not
Knowing how this takes probe, and how long take, also student pricks in one's hands during operation, each not phase of everyone operation
With, the specification that neither one is unified, causes teaching to be pushed slowly, is unfavorable for Students ' Learning.Additionally, existing frog metal probe is many
It is structure as a whole, student experimenting frequent operation, and it is mostly repetitive operation, it is easy to cause probe that deformation, distortion etc. occur
Problem, the probe of integrative-structure is accomplished by integral replacing, causes the serious waste of material, makes instruction cost improve.
Utility model content
The purpose of this utility model is to use for problems of the prior art and a kind of Physiological Experiment of not enough offer
Frog metal probe, this frog metal probe grasps the mode of probe to student has a unified specification, when making student grasp probe
Having regulations to abide by, student operates more easy, accuracy, safe, improves teaching efficiency and quality of instruction.
For realizing this novel purpose, basis is the most novel to be adopted the following technical scheme that, a kind of Physiological Experiment frog metal probe, including
Handle, shank and syringe needle, described handle is arranged on needle tip, and described syringe needle is arranged on shank bottom, and syringe needle top is arranged
Having threaded connector, shank is being arranged to cavity with threaded connector correspondence position, and in cavity inner wall is provided with coupling
Screw thread, described syringe needle is flexibly connected by screw thread with shank, and described shank is disposed with the frog skull penetrating degree of depth from bottom to top
Labelling, entrance cranial cavity sounding mark and frog spinal cord collapse dept labelling, and be reserved with on frog spinal cord collapse dept labelling top
Movable adjustment district.
Based on technique scheme, described needle tip is structure as a whole with handle.
Based on technique scheme, described needle tip is flexibly connected with handle.
Based on technique scheme, described syringe needle is tapered needle.
Based on technique scheme, described handle is tapered handle.
Based on technique scheme, described frog skull penetrating sounding mark distance syringe needle distance is 0.5cm.
Based on technique scheme, described entrance cranial cavity sounding mark distance syringe needle distance is 1.5cm.
Based on technique scheme, described frog spinal cord collapse dept marking path syringe needle distance is 4-6cm.
This utility model has the advantages that Physiological Experiment of the present utility model frog metal probe, change with
Hold the quasi-disunity of pin mark, fault when operating toward student, and easily stab the problems such as hands, at the base of existing frog metal probe
On plinth, labelling pierces through frog skull, entrance cranial cavity and destruction frog spinal cord should play the pin degree of depth, according to piercing through frog skull labelling, permissible
Enough pierce through the skull of the frog, enter cranial cavity from Foramen magnum, according to entering cranial cavity sounding mark, probe is entered cranial cavity, Ke Yibao
Card is sufficiently destroyed brain, determines Labelled Frog spinal cord collapse dept according to the head size of the frog, according to frog spinal cord collapse dept mark
Write down pin and can destroy the spinal cord of the frog completely.Probe after making marks, under student, pin is had regulations to abide by, it is easy to grasp, it is simple to study,
When handling, frog skull penetrating sounding mark can place labelling as forefinger again, and handle only need to be held in the centre of the palm, by forefinger by student
Being placed at frog skull penetrating sounding mark, can easily realize the probe grip posture of standard, easy and simple to handle, standard is united
One, it is simple to teaching.And, conventional frog metal probe is all structure as a whole, but due to teaching probe, student's operation excessively frequency
Numerous, it is easy to damage syringe needle, syringe needle needs integral replacing after damaging, waste resource.Basis is the most novel designs composition by syringe needle with shank
Body structure, syringe needle is broken, and is directly individually replaced syringe needle, effectively reduces use cost and the wasting of resources.
Figure of description
Fig. 1 is this utility model Physiological Experiment frog metal probe structural representation.
Label in figure: 1 is handle, 2 is syringe needle, and 3 is shank, and 4 is movable adjustment district, and 5 is frog skull penetrating sounding mark,
6 for entering cranial cavity sounding mark, and 7 is frog spinal cord collapse dept labelling, and 8 is threaded connector.
Detailed description of the invention
It is described further the most novel below in conjunction with specific embodiment, in order to be more fully understood that this new technique scheme.
Embodiment 1: a kind of Physiological Experiment frog metal probe, sees Fig. 1, including handle 1, shank 3 and syringe needle 2, described
Handle is arranged on needle tip, and handle is structure as a whole with shank, and for ease of grasping, handle is arranged to tapered handle, with pin
It is thin that bar connects end, and upper end is thick.Described syringe needle is arranged on shank bottom, and for ease of piercing through, syringe needle is sharper, and needle design is tapered
Syringe needle, the present embodiment changes the traditional mode that conventional syringe needle is structure as a whole with shank, is flexibly connected with shank by syringe needle, with
Save and use and replacement cost.Particularly as follows: be threaded union joint 8 on syringe needle top, shank 3 is in position corresponding with threaded connector
Installing and be set to cavity, and be provided with the female thread of coupling at cavity inner wall, described syringe needle is flexibly connected by screw thread with shank, institute
State shank and be disposed with frog skull penetrating sounding mark 5, entrance cranial cavity sounding mark 6 and frog spinal cord destruction from bottom to top deeply
Scale designation 7, in order to make probe adapt to the frog of various body sizes, range is more extensive, on frog spinal cord collapse dept labelling
Portion is reserved with movable adjustment district.Especially for the frog that head is big, lower pin can be adjusted flexibly according to the needs of the different frogs
The degree of depth.
In the present embodiment: frog skull penetrating sounding mark distance syringe needle distance is 0.5cm, and this distance the most enough pierces through the frog
Skull enter cranial cavity from Foramen magnum.Entering cranial cavity sounding mark distance syringe needle distance is: 1.5cm, this distance is as probe
Entering the degree of depth in cranial cavity, can be sufficiently destroyed brain, frog spinal cord collapse dept labelling is made at distance syringe needle 4-6cm, this mark
Note determines position according to the head size of the frog, it is ensured that enough destroy the spinal cord of the frog.Before the ratio that in the present embodiment, handle makes
Overstriking, in order to be prone to grasp, and in order to make probe sturdy and durable, prevent syringe needle from bending, syringe needle, shank and the hands in the present embodiment
Handle is material hard, rustless wear-resisting, enough.In use, frog skull penetrating sounding mark can place labelling as forefinger again,
Handle only need to be held in the centre of the palm by student, is placed on by forefinger at frog skull penetrating sounding mark, can easily realize standard
Probe grip posture, has regulations to abide by during lower pin, it is easy to grasps, is especially advantageous in the promotion and implementation of education experiment field.
