Description

Technical Field

[0001] This utility model relates to the field of blood glucose monitoring technology, and in particular to a portable blood collection device. Background Technology

[0002] Blood collection typically refers to the process of obtaining blood samples through veins or arteries for testing or related needs. Common clinical blood collection methods include venous blood collection, cutaneous blood collection, and arterial blood collection. Venous blood collection involves drawing a certain amount of venous blood using a needle, generally used for complete blood counts, blood biochemistry, coagulation function, tumor markers, or other examinations. Cutaneous blood collection involves gently massaging the collection site to induce hyperemia, disinfecting the skin, and allowing it to dry. The skin is then pinched closed from both sides, and the lancet is inserted, allowing blood to flow out naturally through pressure. Collection sites can include the heel, fingers, or earlobes, and this method is mainly used for various micro-examinations or routine examinations. Arterial blood collection generally involves collecting blood from arteries, primarily used for blood gas analysis. Arterial blood can reflect the measured values ​​of blood gases, but this method has high requirements for sample delivery time, testing time, and the quality of the sample itself. Blood collection devices are used to collect blood samples; with societal development, they are also used when patients need to monitor their blood glucose levels.

[0003] Existing devices, such as CN211674258U, are portable lancing devices that include a pen cap, a housing, an activation device, and a loading device. The pen cap is snapped and fixed to one end of the housing and can be rotated and removed. The activation device is located inside the housing, and a guide ring is provided between the activation device and the housing, allowing the activation device to slide axially relative to the housing. The end of the activation device away from the pen cap is connected to the loading device, and one end of the loading device is located inside the housing. This invention separates the center positioning from the loading device. Loading is performed via a push-pull key on the loading device. An internal positioning needle is provided. During blood collection, only the internal device slides; the positioning needle and its housing do not move. This ensures that even if the end of the lancing pen away from the needle is touched during blood collection, blood collection can still be completed smoothly.

[0004] When a worker needs to draw blood from a patient, the worker places the blood collection device against the patient's skin and activates the device to collect blood. However, when carrying the blood collection device, the worker needs to install an additional protective cap to protect the needle. This requires the worker to spend some time installing the protective cap on the device, causing inconvenience when carrying it. Utility Model Content

[0005] The purpose of this invention is to address the inconvenience that workers experience when carrying blood collection devices in existing technologies, and to propose a portable blood collection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a portable blood collection device, comprising a handle, an adjuster, and a protective device.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a protective device, the blood collection device can be carried and used conveniently by workers when they need to carry it. The device draws blood from the patient by pushing the blood collection needle to puncture the patient's skin. Pulling the cavity causes the cavity to move the slider, which is guided by the groove on the guide channel surface and slides. The slider slides and squeezes the push spring, rotating the guide channel, which in turn moves the cavity. When the cavity slides to the designated position, the guide channel moves the cavity. When the cavity is aligned with the bottom of the handle, pushing the cavity causes the cavity to move the slider, which is pushed by the push spring. The cavity is fitted onto the handle. By setting a protective device, the blood collection device can be carried conveniently by workers, avoiding the need for workers to install a protective cap on the bottom of the handle before carrying the blood collection device. This improves the convenience of carrying the blood collection device, reduces the weight of the blood collection device, and enhances its portability. Attached Figure Description
