Description

Technical Field

[0001] This utility model relates to the field of creatinine detection technology, and in particular to a blood sampler for creatinine detection. Background Technology

[0002] Creatinine is a metabolic byproduct of muscle metabolism in the human body, primarily excreted through glomerular filtration. Every 20g of muscle metabolism produces 1mg of creatinine. When meat intake is stable and muscle metabolism remains relatively unchanged, creatinine production remains relatively constant. Blood creatinine comes from both exogenous and endogenous sources. Exogenous creatinine is a byproduct of meat metabolism; endogenous creatinine is a byproduct of muscle tissue metabolism. Clinically, testing blood creatinine is one of the main methods for assessing kidney function. This test requires drawing a certain amount of blood using a sampler, typically a disposable syringe.

[0003] Since the needle is fixedly attached to the front end of the syringe, it cannot be retracted into the syringe after blood is drawn. This can cause medical staff to be pricked by the needle when handling used syringes. Therefore, a blood sampler for creatinine testing is proposed. Utility Model Content

[0013] As a further description of the above technical solution:

[0014] The connecting sleeve is provided with four observation windows, which are arranged in a circular equidistant array.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the connecting sleeve is provided with two limiting grooves, and two limiting blocks are fixedly provided on the outside of the sampler body. The limiting blocks and the limiting grooves are slidably connected.

[0017] As a further description of the above technical solution:

[0018] A second spring is fixedly installed inside the storage hole. A guide plate is fixedly installed at one end of the second spring.

[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with existing technologies, this blood sampler for creatinine testing, by setting up spring one, positioning hole, positioning rod and spring two, after sampling, the two positioning rods are pressed inward at the same time. The positioning rods press the guide plate, and the guide plate presses the spring two on one side. When the positioning rods are retracted into the storage hole, spring one pushes the positioning block, causing the sampler body to move upward. The sampler body drives the needle, causing it to retract into the connecting sleeve. This can effectively prevent medical personnel from being accidentally pricked by the needle when handling the sampler, thereby reducing the risk of cross-infection.

[0021] 2. Compared with existing technologies, this blood sampler for creatinine testing has a rubber anti-slip sleeve, which makes it easier for medical staff to hold during blood collection, allowing for better control of the syringe and preventing slippage. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1 to 4 This utility model provides a blood sampler for creatinine detection: it includes a sampler body 1, a connecting sleeve 2 movably provided on the outside of the sampler body 1, two limiting grooves 9 provided on the inner wall of the connecting sleeve 2, two limiting blocks 10 fixedly provided on the outside of the sampler body 1, the limiting blocks 10 and the limiting grooves 9 are slidably connected, a needle 3 is provided at the bottom of the sampler body 1, two horizontal plates 5 are fixedly provided on the inner wall of the connecting sleeve 2, a spring 6 is fixedly provided at the top of each of the two horizontal plates 5, the top of the spring 6 is fixedly connected to the bottom of the positioning block 111, two sliding grooves 7 are provided on the inner wall of the connecting sleeve 2, a positioning hole 8 is provided on the inner wall of each of the two sliding grooves 7, the positioning hole 8 is adapted to the positioning rod 117, and four observation windows 12 are provided on the connecting sleeve 2, the four observation windows 12 are arranged in a ring equidistant array, the observation windows 12 can facilitate medical personnel to observe the blood sample volume.

[0030] To facilitate the grip of medical personnel, the sampler body 1 is fixedly equipped with an anti-slip sleeve 4. The anti-slip sleeve 4 is three millimeters thick and made of rubber. The anti-slip sleeve 4 can enhance the friction between the sampler and the palm, allowing staff to better control the syringe and prevent it from slipping.

[0031] To achieve the purpose of retracting the needle tip 3, two positioning structures 11 are fixedly provided on the outside of the sampler body 1. The positioning structure 11 includes a positioning block 111 for installation. A receiving hole 112 is provided on one side of the positioning block 111. A positioning rod 117 for positioning is movably installed in the receiving hole 112. A second spring 114 is fixedly provided in the receiving hole 112. A guide plate 115 is fixedly provided at one end of the second spring 114. The guide plate 115 is fixedly connected to one end of the positioning rod 117 on one side. Two sliding grooves 113 are provided on the inner wall of the receiving hole 112. The outer side of the guide plate 115... Two sliders 116 are fixedly installed, and the sliders 116 and the slide groove 113 are slidably connected. After sampling, the two positioning rods 117 are pressed inward at the same time. The positioning rods 117 press the guide plate 115, and the guide plate 115 presses the spring 114 on one side. When the positioning rods 117 are retracted into the receiving hole 112, the spring 16 pushes the positioning block 111, causing the sampler body 1 to move upward. The sampler body 1 drives the needle 3, causing it to retract into the connecting sleeve 2. This can effectively prevent medical personnel from being accidentally pricked by the needle 3 when handling the sampler, thereby reducing the risk of cross-infection.

[0032] Working principle: During blood collection, the sampler body 1 is pressed downwards. The sampler body 1 moves the positioning block 111 and the limiting block 10. The positioning block 111 moves the positioning rod 117. When the positioning rod 117 moves to the position of the positioning hole 8, the spring 114 pushes the guide plate 115. The guide plate 115 moves the positioning rod 117 outwards and pops it out of the positioning hole 8, thus positioning the sampler body 1. At this time, the needle 3 is exposed, and medical personnel can use the device to collect samples. After sampling, both positioning rods 117 are pressed inward simultaneously. The positioning rods 117 press the guide plate 115, and the guide plate 115 presses the spring 114 on one side. When the positioning rods 117 are retracted into the receiving hole 112, the spring 6 pushes the positioning block 111, causing the sampler body 1 to move upward. The sampler body 1 drives the needle 3, causing it to retract into the connecting sleeve 2. This can effectively prevent medical personnel from being accidentally pricked by the needle 3 when handling the sampler, thereby reducing the risk of cross-infection.
