Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a clinical blood sampling device for non-surgical treatment. BACKGROUND

[0002] In clinical medicine, blood sampling is a common and important diagnostic and therapeutic means. However, there are some problems that cannot be ignored in the existing non-surgical treatment and clinical blood sampling process.

[0003] Since blood sampling is usually performed in a state where the patient is awake and not completely fixed, the patient may produce body shaking due to nervousness, pain or involuntary action. In addition, the medical staff may also cause the blood sampling site to be affected by external force to a certain extent due to the operation process, environment and other factors.

[0004] In these cases, the existing blood sampling device often has difficulty in effectively responding to the problem of shaking. The connection between the blood sampling needle and the patient's skin is not stable enough, and the blood sampling needle is prone to falling off when shaking. Once the blood sampling needle falls off, it will not only cause the blood sampling to be interrupted, but also increase the patient's pain and the medical staff's work burden.

[0005] Moreover, the falling off of the blood sampling needle may also cause blood splashing, resulting in the pollution of the surrounding environment and the risk of cross infection. At the same time, the falling off of the blood sampling needle may also lead to insufficient blood collection or contamination of the blood sample, affecting the accuracy of the subsequent test results, which may delay the diagnosis and treatment of the disease.

[0006] In summary, the existing clinical blood sampling device for non-surgical treatment has obvious deficiencies in dealing with the shaking problem in the blood sampling process, which seriously affects the efficiency and quality of blood sampling, and brings many inconveniences and potential risks to patients and medical staff.

[0032] Wherein, the outer wall of blood collection component 5 is provided with limiting component 4, limiting component 4 includes first butterfly seat 41 and second butterfly seat 42, first butterfly seat 41 and second butterfly seat 42 are made of medical grade polyethylene plastic, with certain elasticity and hardness. Its surface is designed with anti-skid texture to increase the friction force when contacting with fingers, prevent slipping during operation, first butterfly seat 41 and second butterfly seat 42 are sleeved on the surface wall of blood collection component 5 and can rotate at an angle, used for limiting and fixing blood collection component 5, medical staff selects appropriate blood collection site, disinfects the skin, then accurately inserts blood collection needle 51 into the patient's vein. During blood collection, if the patient feels slight shaking or the possibility of external force, the medical staff rotates first butterfly seat 41 and second butterfly seat 42 clockwise or counterclockwise, so that they tightly fit the patient's skin and form a certain angle and support, thereby effectively limiting and fixing blood collection needle 51.

[0033] Blood collection component 5 includes blood collection needle 51, which is made of high-quality stainless steel material and is finely polished, with sharp needle tip and smooth surface, to ensure easy insertion into the vein and reduce patient pain. At the same time, blood collection needle 51 is subjected to strict disinfection treatment to ensure aseptic state. The bottom end of blood collection needle 51 is provided with insertion pipe 52, the bottom end of insertion pipe 52 is provided with blood collection seat 53, the bottom end of blood collection seat 53 is provided with vertical pipe 54, blood collection seat 53 and vertical pipe 54 are both hollow tubular structures, and the size of insertion pipe 52 is smaller than that of blood collection seat 53.

[0034] The surface wall of first butterfly seat 41 and second butterfly seat 42 is provided with anti-skid texture, the intersection between first butterfly seat 41 and second butterfly seat 42 and insertion pipe 52 is provided with connecting column 43, first butterfly seat 41 is detachably connected with blood collection needle 51, and second butterfly seat 42 is non-detachably connected with blood collection needle 51.

[0035] The two ends of connecting pipe 2 are respectively inserted and connected with blood collection component 5 and blood transfusion component 3, and the outer surface wall of blood transfusion component 3 is provided with branch pipe for protecting blood transfusion component 3.

[0036] The outer surface wall of blood collection component 5 is provided with protection pipe 1, which protects the internal blood collection needle 51 to avoid infection.

[0037] By adopting the technical scheme above,

[0038] A nurse is taking blood from an elderly patient at a community health service center.

[0039] Using the blood taking device of the present application, the nurse first holds the second butterfly seat 42 to smoothly insert the blood taking needle 51 into the vein of the patient. During the blood taking process, if the patient slightly shakes due to nervousness, the first butterfly seat 41 is detachably connected with the blood taking needle 51 and can rotate around the blood taking needle 51, and the second butterfly seat 42 is not detachably connected with the blood taking needle 51 but can also rotate around the blood taking needle 51. During the blood taking operation, when the blood taking needle 51 is inserted into the vein, the medical staff holds the second butterfly seat 42 to preliminarily prevent the blood taking needle 51 from falling off. Then, the first butterfly seat 41 and the second butterfly seat 42 are rotated towards the vein, and the blood taking needle 51 is limited by the deflection of the first butterfly seat 41 and the second butterfly seat 42, so as to effectively avoid the blood taking needle 51 from falling off due to shaking, and ensure the smooth progress of the blood taking process and the blood taking quality. The blood taking needle is stably fixed, the blood taking is smoothly completed, and the patient does not feel obvious discomfort.

[0040] The working principle is as follows:

[0041] At the beginning of the blood taking operation, the protective tube 1 is detached, and then the blood taking needle 51 is inserted into the vein of the patient. At this time, the medical staff holds the second butterfly seat 42 with the hand to provide initial stability and prevent the blood taking needle 51 from shaking and falling off in the initial insertion stage.

[0042] Then, during the blood taking process, if there are factors that may cause the blood taking needle 51 to shake, the first butterfly seat 41 and the second butterfly seat 42 are rotated towards the vein, so that the positions of the first butterfly seat 41 and the second butterfly seat 42 are deflected. Since the first butterfly seat 41 is detachably connected with the blood taking needle 51 but can rotate around the blood taking needle 51, and the second butterfly seat 42 is not detachably connected with the blood taking needle 51 but can also rotate, the deflection of the first butterfly seat 41 and the second butterfly seat 42 can effectively limit and fix the blood taking needle 51. When the first butterfly seat 41 and the second butterfly seat 42 are deflected, the first butterfly seat 41 and the second butterfly seat 42 are connected with the plug-in tube 52 in a hard friction manner, and the blood taking needle 51 is limited when the first butterfly seat 41 and the second butterfly seat 42 are rotated.

[0043] This limiting and fixing action can reduce the shaking of the blood taking needle 51 due to the movement of the patient, the collision of the external environment or other accidental factors during the blood taking process, thereby greatly reducing the risk of the blood taking needle falling off and ensuring that the blood taking process can be smoothly and safely carried out.

[0044] Finally, it should be noted that the above embodiments are merely intended for the purpose of illustration, and are not intended to limit the present application. Based on the above description, those skilled in the art can make other variations or modifications of the present application in different forms. Here, it is not necessary or possible to enumerate all the embodiments. The obvious variations or modifications derived therefrom are still within the scope of the present application.
