Abstract

The utility model discloses a protection appliance for the extracorporeal part of the femoral artery and vein of the big mouse, which consists of a coat, at the edge of which some holes for stretching the four legs, tail and head of a mouse are opened. The back part of the coat is provided with an interlayer, in which PE tube for protecting the intubatton is positioned and the exit of the PE tube is opened at the interlayer approaching to the neck and back area of the mouse. The utility model solves many difficult problems, such as after the intubatton, to fix the extracorporeal part is hard, which is easy to drop off and is inclined to be worried by the mouse, resulting in difficulty for sampling, drug administration, check on the body and also is likely to cause damage or infection to the mouse when given traditional subcutaneous puncture. The utility model can conduct sampling, drug administration or check on the body, so that the utility model is accurate and reliable to analyze the experimental data.

Description

The protector of rat thigh venous incubation outer body

Technical field

This utility model relates to a kind of protector of outer body when using rat thigh artery and vein intubate, is specially adapted to take a sample under the clear-headed or active state rat, administration or detection in vivo.

Background technology

In the prior art, the outer body of rat thigh artery and vein intubate is generally adopted the subcutaneous puncture protection, and subcutaneous puncture easily causes problems such as rat somatic damage or infection.Still there is not at present the correlation technique report that solves this difficult problem.

Summary of the invention

Task of the present utility model provides a kind of protector of rat thigh venous incubation outer body; this protector has solved after the rat intubate outer body and has been difficult to fix, comes off easily, is easily baited and cause being difficult to difficult problems such as sampling, administration, detection in vivo; and reduced the influence of extraneous factor, made the experimental analysis data more accurately, reliably.

The protector of the rat thigh venous incubation outer body that this utility model provides; comprise overcoat; the overcoat edge is respectively arranged with the aperture of rat extremity, tail and head; extremity, tail and head for rat stretch out overcoat; on the back of overcoat interlayer is set; place the PE flexible pipe that is used to protect intubate in the interlayer, offer the outlet of PE flexible pipe near Mus nape portion place at interlayer.

The protector of rat thigh venous incubation outer body of the present utility model has following advantage:

(1) with the PE flexible pipe outer body of intubate is fixed in the back of rat, has solved after the rat intubate outer body and be difficult to fix, come off easily, easily baited and cause being difficult to difficult problems such as sampling, administration or detection in vivo by Mus;

(2) solve traditional subcutaneous puncture and easily caused problems such as rat somatic damage or infection;

(3) sampling, administration or detection in vivo are fixed on rat back with intubate, are not subjected to the influence of rat motor, have reduced the external influence factor in the experimentation, make that the analysis experimental data is accurate, science is reliable, helps development of scientific research;

(4) can be rat take a sample under the clear-headed or active state, administration or detection in vivo, experiment method is flexible.

The specific embodiment

Be further described below in conjunction with embodiment and accompanying drawing thereof.

Referring to Fig. 1, this is the embodiment of the protector of rat thigh venous incubation outer body.The protector of this rat thigh venous incubation outer body comprises overcoat 1, this rat overcoat 1 is made suitable size by elastic fabrics such as elasticity cottons, the edge of overcoat 1 offers the elasticity aperture 7 that overs rat extremity, tail and head respectively, make head, extremity and the tail of rat expose overcoat 1, and can be free movable; On the both sides of overcoat 1 adhesive-layer 3 is set, can does suitably fine setting, overcoat 1 is securely fixed on one's body the rat according to the size of rat health.

Interlayer 2 is set on the back of overcoat 1, and interlayer 2 internal fixation have PE flexible pipe 4, and PE flexible pipe 4 is used for fixing and protects the intubate 6 that sampling, administration or detection in vivo are used; On interlayer 2, offer PE flexible pipe outlet 5, from here PE flexible pipe 4 is derived near rat nape portion place; One end of intubate 6 passes PE flexible pipe 4, penetrates in the rat body, and the other end can be used for sampling, administration or detection in vivo after the PE flexible pipe exports 5 derivation.

Claims

1. the protector of a rat thigh venous incubation outer body; it is characterized in that comprising overcoat; the overcoat edge offers the aperture that overs rat extremity, tail and head respectively; overcoat is provided with interlayer on the back; place the PE flexible pipe that is used to protect intubate in the interlayer, offer the outlet of PE flexible pipe near Mus nape portion place at interlayer.

2. protector according to claim 1 is characterized in that said overcoat two ends are provided with adhesive-layer.
