Description
Technical Field
The utility model relates to the field of medical auxiliary equipment, in particular to an inner canthus hemostix for animal experiments.
Background
The medial canthus blood sampling is a method for collecting relatively much blood when the animal is alive, and the operation is of great significance for dynamically observing cytological changes of animal blood cells, detecting cytokines and the like.
The following two methods are currently used for medial canthus blood sampling: firstly, a capillary glass tube method comprises the specific steps that a mouse is fixed by the left hand, an eyeball at one side protrudes out, the prepared capillary tube is held by the right hand and is inserted into the inner eyelid of the mouse along an angle of 45 degrees, the capillary tube is twisted, and blood flows into an EP tube along the wall of the tube; the 'improved' capillary glass tube method is characterized in that blood vessels are self-prepared and used for taking blood from inner canthus, the method comprises the steps of taking 1 suction head of 200ul, cutting off a part with the front end of 0.3-0.4cm according to specific conditions, taking 1 capillary glass tube with the diameter of about 1mm, inserting the suction head along the upper end of the suction head, pulling out the suction head from the lower end to a part with the length of 0.3-0.5mm overlapped with the glass tube, properly burning the suction head and the glass tube by an alcohol lamp, enabling the two parts to be tightly connected, cutting the suction head and the glass tube at proper length by using a small grinding wheel, and breaking off the capillary tube at the redundant part, wherein the length of the exposed capillary tube is 2.0-2.5 cm. The first method has the following disadvantages: firstly, the capillary glass tube has large brittleness, and is easy to be broken in an eyeball during blood sampling, so that the eyeball is damaged; secondly, the capillary glass tube is easy to fall off in the EP tube, and hemolysis can be caused if the capillary glass tube is not properly treated, so that the experimental result is influenced. The second method has many disadvantages, firstly, the operation of burning the suction head and the intussusception part of the glass tube by the alcohol lamp is not easy to be mastered, the fire power is often too large in the actual operation process, the suction head is easy to be burnt excessively, and the problem of the infirm connection of the two is caused when the fire power is too small; secondly, blood below the capillary glass tube orifice of the intussusception part is not easy to suck out, so that blood waste is caused; finally, the manufacturing process is very complicated, time-consuming and labor-consuming, sterile operation is difficult to achieve in the whole process, and blood samples are very easy to pollute to influence experimental results, periorbital infection of animals and the like. Based on the above problems, there is a need for a dedicated angular hemostix with simple operation and less damage.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the problems in the prior art and provide an inner canthus hemostix for animal experiments.
For realizing above-mentioned technical purpose, reach above-mentioned technological effect, the utility model discloses a following technical scheme realizes:
the inner canthus blood sampler for animal experiments comprises a blood storage tube body for storing blood, wherein the lower end of the blood storage tube body is communicated with a blood sampling tip for extending into the inner canthus to take blood.
Furthermore, the upper end of the blood storage tube body is of an open structure, and a tube cap matched with the blood storage tube body is arranged at the open structure of the blood storage tube body and used for opening or sealing the upper end of the blood storage tube body.
Furthermore, the opening structure of the blood storage tube body and the tube cap are in threaded screwing fit or interference sleeving fit.
Further, the tube cap comprises a plurality of different colors, and each color corresponds to the type of anticoagulant added in the blood storage tube body in advance so as to be convenient for identification and selection.
Furthermore, a tip sleeve matched with the blood sampling tip in a sleeved mode is arranged on the blood sampling tip and used for sealing the blood sampling tip to prevent pollution.
Furthermore, the outer side surface of the blood storage tube body is vertically provided with scale marks for observing the blood volume in the blood storage tube body.
The utility model has the advantages that:
the utility model discloses simple structure, it is convenient to make, with low costs, convenient to use can save assistant's assistance during the blood sampling to be convenient for preserve, can prevent to pollute.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The reference numbers in the figures illustrate: 1. a blood storage tube body 2, a blood sampling tip 3, a tube cap 4, a tip sleeve 5 and scale marks.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Referring to fig. 1, an angular blood collector for animal experiments includes a blood storage tube body 1 for storing blood, the lower end of the blood storage tube body 1 is communicated with a blood collection tip 2, in this embodiment, the blood storage tube body 1 and the blood collection tip 2 are integrally formed, and are made of plastic and used for collecting blood extending into the angular region.
The upper end of the blood storage tube body 1 is of an open structure, and a tube cap 3 matched with the blood storage tube body 1 is arranged at the open structure of the blood storage tube body 1 and used for opening or sealing the upper end of the blood storage tube body 1.
The opening structure of the blood storage tube body 1 is in threaded screwing fit or interference sleeve fit with the tube cap 3, and in the embodiment, the interference sleeve fit is adopted, so that the structure is simple and practical.
The pipe cap 3 is including a plurality of different colours to every colour is corresponding with the anticoagulant kind that adds in advance in the blood storage tube body 1, so that the discernment is chooseed for use, in addition, if do not add the anticoagulant, also reserve the pipe cap 3 of a colour and correspond rather than, for example add the design of anticoagulant EDTA for purple pipe cap, do not add the design of anticoagulant for yellow pipe cap etc..
