Description

Technical Field

[0001] The utility model relates to a blood sampling device, in particular to a blood sampling device for animal quarantine. Background Art

[0002] At present, there are two main types of blood collection equipment, namely syringe blood collection and vacuum tube blood collection. The above two methods are selected according to different blood collection objects. When the blood collection object is a natural person, vacuum tube blood collection is generally selected. Vacuum tube blood collection refers to the use of negative pressure vacuum glass tubes and venous blood needles to collect blood. When collecting blood, the venous blood needle is inserted into the human vein. When the blood collection object is livestock, syringe blood collection is generally selected because livestock have thicker or harder fur, which makes it difficult to insert the venous blood needle. However, syringe blood collection has the following disadvantages: (1) After the syringe is collected, the pull rod of the syringe is generally in a pulled-out state. Once it is subjected to external force, the pull rod will push the syringe and blood will overflow, causing pollution; (2) After the syringe collects blood, the blood needs to be transferred to the corresponding container, which adds an operation and reduces the efficiency of blood collection.

[0003] Based on this, it is necessary to improve the syringe used for blood collection. Utility Model Content

[0004] Technical purpose: In order to overcome the deficiencies in the prior art, the utility model provides a blood sampling device for animal quarantine, which is convenient for storing the collected blood.

[0006] An adsorption chamber, wherein a piston is slidably disposed in the adsorption chamber, and the piston can change the vacuum degree of the adsorption chamber by moving up and down;

[0007] An accommodating chamber, wherein the accommodating chamber and the adsorption chamber can be connected to or disconnected from each other;

[0008] The injection needle can be connected to or separated from the accommodating cavity.

[0009] Preferably, the adsorption chamber is provided with an opening, the opening is covered with a rubber plug, the piston is connected to a pull rod, one end of the pull rod passes through the rubber plug and is placed outside the adsorption chamber, and the greater the length of the pull rod extending into the adsorption chamber, the greater the vacuum degree of the adsorption chamber.

[0010] Preferably, it also includes a connecting needle; the accommodating chamber is provided with a first plug and a second plug, the first plug is arranged at one end of the accommodating chamber, the first plug is made of rubber material, and one end of the injection needle can pass through the first plug and extend into the accommodating chamber; the second plug is made of rubber material, and the connecting needle is connected with the adsorption chamber through the second plug.

[0013] Preferably, an annular convex ring is provided in the fixing buckle, the communicating needle is connected to the convex ring, and a channel communicating with the adsorption chamber is provided in the convex ring.

[0014] The utility model has the following beneficial effects:

[0015] (1) In the present device, the vacuum degree of the adsorption chamber is increased only after the pull rod is pushed into the adsorption chamber, thereby absorbing blood. After the blood is collected, the pull rod is completely placed in the adsorption chamber, rather than being in a pulled-out state like the existing syringe, thereby avoiding blood spillage due to unexpected circumstances.

[0016] (2) After blood collection, the accommodating chamber can be taken out separately, thereby improving blood collection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is combined with Figure 1 To Attachment Figure 4 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0023] A blood sampling device for animal quarantine comprises an adsorption chamber 1, a containing chamber 3, an injection needle 4 and a connecting needle 9. A piston 2 is slidably arranged in the adsorption chamber 1, and a pull rod 6 is connected to the piston 2, and the pull rod 6 is used to drive the piston 2 to slide up and down in the adsorption chamber 1. The upward movement of the piston 2 can change the vacuum degree in the adsorption chamber 1. An opening is arranged upward at one end of the adsorption chamber 1, and a rubber plug 5 is arranged and connected to the opening. The other end of the pull rod 6 away from the piston 2 passes through the rubber plug and is placed outside the adsorption chamber 1 to form an operating part. The setting of the operating part can facilitate the staff to push the pull rod 6 into the adsorption chamber 1.

[0024] See attached Figure 2 , the piston 2 divides the adsorption chamber 1 into an upper chamber and a lower chamber, and the vacuum degree of the upper chamber increases when the piston 2 moves downward. An air outlet should be provided at the bottom of the lower chamber to prevent the piston 2 from being difficult to move downward due to pressure. A fixing buckle 10 for fixing the accommodating chamber 3 is integrally formed with the adsorption chamber 1, and the fixing buckle 10 is arranged in parallel with the adsorption chamber 1. The accommodating chamber 3 can be fixedly engaged in the fixing buckle 10. A ring-shaped convex ring 13 is provided in the accommodating chamber 3, and the connecting needle 9 is connected to the convex ring 13. The injection needle 4 is connected to the end of the fixing buckle 10, and the extension direction of the injection needle 4 is consistent with that of the connecting needle 9, which is the sliding direction of the piston 2. The connecting needle 9 is arranged on the convex ring 13, and a channel connected to the adsorption chamber 1 is provided in the convex ring 13. The injection needle 4 includes a needle head 11 and a connecting part 12, wherein the needle head 11 is further divided into two parts, and the needle head 11 extends to both sides of the connecting part 12 respectively. One end of the injection needle 4 is used to pierce into the livestock body, and the other end of the injection needle 4 is inserted into the accommodating chamber 3. The accommodating chamber 3 is provided with a first plug 7 for the injection needle 4 to pierce and a second plug 8 for the connecting needle 9 to pierce. The first plug 7 is provided at one end of the accommodating chamber 3, and the second plug 8 is provided at the middle position of the accommodating chamber 3. When the connecting needle 9 passes through the second plug 8 and extends into the accommodating chamber 3, the accommodating chamber 3 and the adsorption chamber 1 are mutually connected. The first plug 7 and the second plug 8 are both made of rubber.

[0025] When sampling, the device first connects the accommodating chamber 3 to the fixed buckle 10, and allows the connecting needle 9 to penetrate the second plug 8, so that the adsorption chamber 1 and the accommodating chamber 3 are connected to each other. Next, the injection needle 4 is installed, and one end of the injection needle 4 is allowed to penetrate the first plug 7 and extend into the accommodating chamber 3. Then, the pull rod 6 is pushed into the adsorption chamber 1 to complete the blood sampling. Finally, the accommodating chamber 3 is removed from the fixed buckle 10.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
