[0024] In order to make the purpose and advantages of the utility model more clear and apparent, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope of the utility model specifically requested.

[0025] As shown in Figures 1-3 A physical examination nursing blood collection device, comprising a first connecting part 2 and a blood collection container 4 through a third connecting part 3, the first connecting part 2 end is provided with an insertion end 23, the other end of the first connecting part 2 is provided with a blood input end 1, and the blood input end 1 is through the first connecting part 2.

[0026] Further, the blood collection container 4 top is provided with a second connecting part 5, the third connecting part 3 is screwed with the second connecting part 5, the first connecting part 2 is movably inserted with the third connecting part 3 and is inserted at the end of the second connecting part 5, the second connecting part 5 is provided with a sealing part 6 inside, the sealing part 6 is provided with an elastic film 61 outside, the insertion end 23 is screwed vertically in the surface of the sealing part 6 through the third connecting part 3, and penetrates the sealing part 6 and the elastic film 61.

[0027] Among them, the blood input end 1 is provided with a needle away from one end of the first connecting part 2, and the needle at both ends of the blood input end 1 is sleeved with a protective sleeve outside the first connecting part 2 when not in use, and the two protective sleeves are removed respectively when in use, and the first connecting part 2 is inserted at the top of the third connecting part 3, and before use, the third connecting part 3 and the second connecting part 5 are not completely screwed, that is, when the first connecting part 2 is inserted at the top of the third connecting part 3, the bottom end of the first connecting part 2 does not penetrate or does not completely penetrate the sealing part 6.

[0028] According to the above structure, the working principle is:

[0029] In use, first, the blood sampling input end 1 is inserted at the blood sampling site, the first connecting part 2 is inserted at the top of the third connecting part 3, and the third connecting part 3 is screwed with the second connecting part 5 more tightly by rotating the third connecting part 3 or the blood sampling container 4. At this time, the first connecting part 2 end is continuously inserted into the end 23, and gradually penetrates the sealing part 6 and the elastic film 61. When the sealing part 6 and the elastic film 61 are completely penetrated, the vacuum state in the blood sampling container 4 can realize the suction of blood. After the above blood sampling process is completed, the blood sampling container 4 is replaced or the needle at the end of the blood sampling input end 1 is pulled out.

[0030] In addition, the above-mentioned blood sampling container 4 includes a vacuum tube, a blood sampling bag, etc., for collecting blood.

[0031] The above structure only includes three parts, and the connecting part structure is simple and easy to assemble, which is beneficial to mass production, and the production process is simple. According to the above use principle, the use method is simple and easy to operate.

[0032] Please refer to Figure 2 and Figure 3 , the distance between the bottom end of the insertion end 23 and the top end of the first connecting part 2 is greater than the thickness of the top of the third connecting part 3.

[0033] Further, the first connecting part 2 and the insertion end 23 are provided with a first necking extension 21, and the first necking extension 21 is interference fitted with the first insertion slot 31 opened at the top of the third connecting part 3.

[0034] Alternatively, the first necking extension 21 and the insertion end 23 are provided with a second necking extension 22, and the second necking extension 22 is interference fitted with the second insertion slot 32 opened in the middle of the third connecting part 3.

[0035] When one or both of the above two conditions exist, the effect is to avoid the first connecting part 2 from the top of the third connecting part 3 when the third connecting part 3 and the second connecting part 5 are rotated, and to ensure the stability during the blood sampling process and avoid falling off.

[0036] Please refer to Figure 2 and Figure 3 , the sealing part 6 and the elastic film 61 are interference inserted at the top of the second connecting part 5, and are protruding and expanding to fill between the second connecting part 5 and the second insertion slot 32, and the inner diameter of the second insertion slot 32 is smaller than the diameter of the top of the sealing part 6

[0037] In addition, to achieve a better user experience, a spike or an inclined opening is provided at the end of the insertion end 23 to achieve a stable connection between the sealing part 6 and the elastic membrane 61. Furthermore, by setting the opening at an inclination, the size of the insertion opening can be controlled by adjusting the insertion depth during blood collection, thereby controlling the blood collection speed and suction force, which can be adjusted for different blood collection test subjects.

[0038] In addition, since the elastic membrane 61 is an elastic film, preferably a film material with elasticity such as polytetrafluoroethylene, the size of the rupture opening of the elastic membrane 61 can be controlled by the degree to which the insertion end 23 punctures the elastic membrane 61, and the blood flow rate and suction force can also be controlled.

[0039] In this application, a baffle or guide plate is also provided inside the blood collection container 4 to guide the blood to the side wall, so as to avoid the blood being sprayed irregularly on the inner wall of the blood collection container 4 due to the different degrees of deformation of the elastic membrane 61, which would affect the control and observation of the blood volume.

[0040] The aforementioned elastic membrane 61 can also achieve vacuum sealing before blood aspiration. By adhering the elastic membrane 61 to the surface of the sealing part 6, the pores on the surface of the sealing part 6 are blocked, thereby improving the maintenance of the vacuum inside the blood collection container 4. Therefore, during use, the elastic membrane 61 can also enhance the protection of the blood sample.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
