Description

Technical Field

[0001] The utility model relates to the technical field of biochemical detection, in particular to a disposable convenient blood collector. Background Art

[0002] There are various types of blood collection devices, among which medical testing devices composed of a syringe and a blood collection needle are the most widely used. When a nurse holds the syringe and presses the head of the blood collection needle against the patient's limb, the sheath retracts under the elastic force of the skin, causing the needle to protrude and pierce the skin to cause micro-injury. When the blood collection needle is removed, the sheath resets again under the action of a reset spring to cover the needle to prevent the needle from being exposed and contaminated or accidentally stabbing the human body. When the blood collection needle is removed, the cavity surrounded by the syringe and the skin gradually increases, forming an instantaneous negative pressure, which is conducive to the collection of blood samples. However, after using a vacuum blood collection tube to draw blood, the syringe and the blood collection tube need to be assembled, which is too troublesome. Therefore, a disposable and convenient blood collection device is needed.

[0003] Currently, the most common way of drawing blood in hospitals is to use a vacuum blood collection tube to draw blood. However, before use, the needle and the blood collection tube need to be assembled and then blood is drawn. During the process, the nurse needs to assemble them manually, which increases the blood collection time and affects the subsequent work progress. Therefore, a disposable and convenient blood collection device is needed. Utility Model Content

During the process, the nurse needs to assemble them manually, which increases the blood collection time. To achieve the above purpose, the utility model provides the following technical solutions: a disposable convenient blood collector, including a blood collection tube, one side of the blood collection tube is provided with a simple component; the simple component includes a sealing rubber cover, the sealing rubber cover is clamped on one end of the blood collection tube, the inner wall of the sealing rubber cover is fixedly connected with a connecting tube 1 and the connecting tube 1 passes through one end of the blood collection tube, the other end of the connecting tube 1 is fixedly connected with a liquid one-way valve, one side of the sealing rubber cover is distributed with a disposable connecting strip in an annular array, the other end of the disposable connecting strip is fixedly connected with a syringe, the other end of the syringe is fixedly connected with a connecting tube 2 and the other end of the connecting tube 2 is clamped on the inner wall of the connecting tube 1.

[0009] Further preferably, a card slot is opened on one side of the vacuum tank, and a spring is movably sleeved on the outer wall of one side of the vacuum tank, and one end of the spring is fixedly connected to the other side of the connecting ring. By installing the disposable connecting piece and the breakthrough tube in the secondary extraction assembly, when the amount of blood sample in the blood collection tube is insufficient to support the test, the vacuum tank is connected to the test tube through the breakage of the disposable connecting piece, and then the patient can be drawn blood for the second time, avoiding the situation that the amount of blood sample in the test tube is insufficient to support the test during use, and the patient may need to undergo a second needle insertion for blood drawing, which is beneficial to improving the practicality of the device.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the utility model, by installing the disposable connecting strip and the connecting tube in the simple assembly, after the blood is drawn, the syringe can be manually pulled apart from the blood collection tube, and during the blood drawing, since the syringe and the test tube are connected in an integrated manner, the blood can be prevented from being contaminated. In this process, the assembly steps before blood drawing can be avoided, which is conducive to shortening the blood drawing time of the device;

A pushing rod 211 is fixedly connected to the side surface of the adjusting piece 210 and the pushing rod 211 passes through the slide groove 209. In the manufacture of the blood collector, the blood collection tube 1 and the vacuum tank 304 are kept in a vacuum state. When the blood collector is used, the operator's thumb first pushes the pushing rod 211. When the pushing rod 211 moves, the adjusting piece 210 drives the movement of the blood collection needle tube 208, so that the length of the blood collection needle tube 208 can be adjusted, and the blood collection tube 207 also moves accordingly. At the same time, the blood collection tube 207 is coiled inside the syringe 205. After the blood collection needle tube 208 is inserted into the skin, blood flows from the blood collection needle tube 208 into the blood collection tube 207, and then from the blood collection tube 207 through the connecting tube 206 to the liquid one-way valve 203, and then flows into the blood collection tube 1.

[0022] In this embodiment, Figure 5 and Figure 6As shown, a secondary extraction component 3 is provided on the other side of the blood sampling tube 1, and the secondary extraction component 3 includes a gas one-way valve 301, and the gas one-way valve 301 is fixedly connected to the other end of the blood sampling tube 1, and a disposable connecting piece 302 is fixedly sleeved in the hole of the gas one-way valve 301 away from the blood sampling tube 1, and a connecting ring 303 is fixedly connected to the side of the gas one-way valve 301 away from the blood sampling tube 1, and a vacuum tank 304 is fixedly sleeved on the inner wall of the connecting ring 303, and a breakthrough tube 305 is fixedly connected to one side of the vacuum tank 304, and a card is provided on one side of the vacuum tank 304. Groove 306, the outer wall of one side of the vacuum tank 304 is movably sleeved with a spring 307, and one end of the spring 307 is fixedly connected to the other side of the connecting ring 303. When the blood inside the blood collection tube 1 is filled to a certain extent, the amount of blood sample is insufficient to support the detection requirements, and the vacuum tank 304 is manually pressed to insert the breakthrough tube 305 and destroy the disposable connecting piece 302 at the same time, thereby connecting the vacuum tank 304 with the blood collection tube 1, and the excess gas in the blood collection tube 1 enters the vacuum tank 304, so that the air pressure of the blood collection tube 1 is reduced, and then blood can be drawn again for replenishment.

[0023] The use method and advantages of the utility model: The disposable convenient blood collection device, when in use, has the following working process:

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in the manufacture of the blood collection device, the blood collection tube 1 and the vacuum tank 304 are kept in a vacuum state. When the blood collection device is used, the operator's thumb first pushes the push rod 211. When the push rod 211 moves, the adjustment member 210 drives the movement of the blood collection needle tube 208, so that the length of the blood collection needle tube 208 can be adjusted, and the blood collection tube 207 also moves accordingly. At the same time, the blood collection tube 207 is coiled inside the syringe 205. After the blood collection needle tube 208 is inserted into the skin, blood flows from the blood collection needle tube 208 into the blood collection tube 207, and then from The blood sampling tube 207 reaches the liquid one-way valve 203 through the connecting tube 206, and then flows into the blood sampling tube 1. When the blood inside the blood sampling tube 1 is filled to a certain extent, the amount of blood sample is insufficient to support the detection requirements. By manually pressing the vacuum tank 304, the breakthrough tube 305 is inserted and the disposable connecting piece 302 is destroyed, thereby connecting the vacuum tank 304 with the blood sampling tube 1. The excess gas in the blood sampling tube 1 enters the vacuum tank 304, reducing the air pressure in the blood sampling tube 1, and blood can be drawn again for replenishment.
