Description

Animal eye blood sampling device

Technical Field

The utility model belongs to the technical field of the medical treatment, concretely relates to animal eye device of getting blood.

Background

Blood is an important body fluid of an organism, contains various components such as cell components (white blood cells, red blood cells and the like), ion components (potassium, sodium, chlorine, calcium and the like), water, fat, amino acid, cell factors and the like, possibly contains bacteria and circulating tumor cells, can know the physiological and pathological states of the organism through analysis of the components in the blood, and has important significance in basic research and disease diagnosis, so that the operation which is common in animal experiments when the blood is collected for detection is carried out. The existing animal blood taking method comprises tail blood taking, namely tail vein needling and tail tip cutting can be adopted; taking blood from eyes by retrobulbar venous plexus blood taking method; collecting blood from large blood vessel by using carotid artery (venous), femoral artery (venous), abdominal aorta, etc.; taking blood from heart; cutting off the head and taking blood, etc. The method for taking blood from the retrobulbar venous plexus at the eye part comprises the following steps: a1 ml syringe or a 10ml long glass tube (one end of which is fired and drawn into a capillary tube having a diameter of 1 to 1.5 mm) was connected to the needle with a No. 7 gauge. When blood is taken, the left hand grasps the skin between the two ears of the mouse to fix the head, gently presses the two sides of the neck to block the backflow of the head veins, so that the eyeballs are fully protruded outwards, and the retrobulbar venous plexus is congested with blood. The right hand syringe or glass tube was inserted into the inner canthus and rotated in the direction of the fundus oculi. Insertion depth: the mouse is 2-3 mm, and the rat is 4-5 mm. Because of the blood pressure, blood flows into the tube automatically, the needle or the glass tube is pulled out, and the left hand is relaxed. In order to prevent bleeding of the puncture hole, the eyeball can be pressed by gauze to achieve the purpose of hemostasis, blood can be repeatedly collected from the same puncture hole after a plurality of minutes, 0.2ml of blood can be collected from a mouse once, and 0.5ml of blood can be collected from a rat once.

Often, the mouse needs to be inverted when taking blood from the eye, then a blood sampling tube is connected outside a long glass tube inserted into a posterior venous plexus of an eyeball, or the eyeball of the mouse is directly removed, the eye part is aligned with the blood sampling tube, then the blood is dripped, the blood is dripped by gravity when taking blood in the prior art, the blood sampling amount is small, and the posture that the animal is inverted and aligned with the blood sampling tube by hands is inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the weak point among the prior art, provide an animal eye device of getting blood that can maintain the animal handstand, conveniently take a blood sample.

In order to solve the technical problem, the utility model adopts the following technical scheme: an animal eye blood taking device comprises a fixed plate and a base, wherein a vertical rod is arranged in the middle of the base, a steering engine is fixed on the upper portion of the vertical rod, and two pin holes are formed in a power output shaft of the steering engine;

the top of fixed plate is fixed with the installation cover, the axis of installation cover sets up along the horizontal direction, two perforations have been seted up at the top of installation cover, the installation cover suit is on the power output shaft of steering wheel, two perforations and two corresponding settings of pinhole, the bolt is worn to be equipped with in pinhole and the perforation that corresponds, the upper portion of fixed plate sets up two low limbs fixed columns, all be connected with first tether on two low limbs fixed columns, the middle part left side of fixed plate is provided with two truck fixed columns, the middle part right side of fixed plate is connected with the fixed band, the end connection of fixed band has the second tether, the lower part of fixed plate is provided with two ear fixed columns, be connected with the clip through the third tether on the ear fixed column, the lower tip of fixed plate is provided with two snap rings.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the novel technology utilizes a fixed plate to fix an animal, keeps a long glass tube in an eyeball of the animal or a blood collection tube with an eye aligned to the lower part, inverts the fixed plate upside down to enable the animal to be in an inverted shape, then fixes the fixed plate on a power output shaft of a steering engine through an installation sleeve, can drive the fixed plate to swing back and forth at 30 degrees, and further promotes whole body blood to enter the head of the animal and further enter the blood collection tube by means of gravity and swing; overall structure reasonable in design, the animal relies on the fixed plate to fix, does not need the supplementary handstand that keeps of people, and it is more convenient to use.
