Specific embodiments

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Such as Figures 1-5As shown in the figure, a new type of flying needle blood collection device includes a blood collection device body. The blood collection device body includes a rectangular parallelepiped-shaped housing 1. Inside the housing 1, there is a partition plate 8. Above the partition plate 8, there is a baffle 13. The rear part of the baffle 13 is connected to a pull rod 4. A spring 14 is sleeved outside the pull rod 4. There is a through hole on the rear side wall of the housing 1 for the pull rod 4 to pass through. The rear part of the pull rod 4 is connected to a first handle 5; in the front part of the baffle 13, there is a pushing member. The pushing member includes a fixing plate 12 attached to the front side of the baffle 13. The lower part of the fixing plate 12 is connected with two push rods 17 arranged side by side. In the front part of the partition plate 8, there is a first opening groove 7 adapted to the push rods 17; the housing 1 includes a bottom plate 6. Between the bottom plate 6 and the partition plate 8, there is an inclined slideway. On the bottom plate 6, there is a second opening groove 10 adapted to the first opening groove 7; on the front side of the bottom plate 6, there is a blood collection needle outlet 11 communicated with the slideway. On the rear side of the bottom plate 6, there is a blood collection needle installation port 9 communicated with the slideway. In the middle of the bottom plate 6, there is also a horizontally arranged first strip-shaped opening. The blood collection needle outlet 11 and the blood collection needle installation port 9 are communicated through the strip-shaped opening. This design is simple in structure and convenient to use. Through the cooperation of components such as the partition plate 8, the spring 14 and the pushing member, the blood collection needle can be quickly ejected, with a fast needle insertion speed, little pain to the blood donor, and when the housing 1 is placed on the arm of the blood donor, the blood collection needle is hidden in the housing 1, which can effectively relieve the psychological pressure of the blood donor and reduce the occurrence of the situation that the hand of the blood collector is pricked by the needle.

[0029] The thickness of the front part of the partition plate 8 gradually decreases from front to back, and the thickness of the front part of the bottom plate 6 gradually increases from front to back to facilitate the formation of an inclined slideway. Preferably, the inclination angle of the slideway is not greater than 15°.

[0030] The first strip-shaped opening penetrates through the bottom plate 6, and the width of the rear part of the first strip-shaped opening gradually increases from front to back to facilitate the passage of the hose connected to the blood collection needle, ensure the use effect of the blood collection device body, and during the process of the blood collection needle piercing into the arm of the blood donor, the hose is restricted by the first strip-shaped opening, so that the blood collection needle on the front side of the hose always remains above the first strip-shaped opening, which is beneficial to ensuring the accuracy of the blood collection needle piercing. The length of the bottom plate 6 is less than the length of the partition plate 8, so as to form a space for placing the hose below the housing 1 and can also adapt to a longer hose in a curved shape.

[0031] The width of the second opening groove 10 is greater than the width of the first opening groove 7 to facilitate the sliding of the push rods 17.

[0032] A sponge pad is attached to the inner wall of the front side of the housing 1 to form a buffer through the sponge pad and avoid the direct contact between the pushing member and the inner wall of the front side of the housing (END]]

[0033] A second handle 3 is provided at the rear side above the housing 1. A locking rod 15 is connected to the lower part of the second handle 3. A second strip-shaped opening 2 for passing through the locking rod 15 is provided on the upper side wall of the housing 1. An installation plate arranged vertically is provided inside the housing 1. The middle part of the locking rod 15 is connected to the installation plate through a rotating shaft. A hook is provided at the lower part of the locking rod 15. At least one first annular groove 16 for engaging with the hook is provided in the middle part of the pull rod 4. After the blood collection personnel pull the first handle 5 to a predetermined position, the pull rod 4 drives the baffle 13 to compress the spring 14, and rotate the second handle 3, so that the hook at the lower part of the locking rod 15 engages with the first annular groove 16, thereby restricting the movement of the pull rod 4. In order to ensure the use effect of the locking rod 15, the hook and the locking rod 15 adopt an integrated structure.

[0034] A second annular groove for engaging with the hook is provided at the rear part of the pull rod 4, that is, a second annular groove is provided on the pull rod 4 near the first handle 5, so as to facilitate the fixation of the first handle 5 when the blood collection device body is not in use.

[0035] A triangular protrusion corresponding to the position of the blood collection needle outlet 11 is provided on the upper surface of the housing 1 to facilitate the blood collection operation of the blood collection personnel.

[0036] In the use of this design, the blood collection personnel pull the first handle 5 backward, drive the baffle 13 to compress the spring 14 through the pull rod 4, and toggle the second handle 3 to make the hook at the lower part of the locking rod 15 engage with the first annular groove 16 in the middle part of the pull rod 4, thereby restricting the movement of the pull rod 4. Place the blood collection needle into the slideway from the blood collection needle installation port 9, then place the housing 1 on the arm of the blood collection person, and align the middle of the blood collection needle outlet 11 on the front side of the housing 1 with the blood collection position on the arm of the blood collection person. Toggle the second handle 3 again to make the hook disengage from the first annular groove 16 and release the spring 14, and drive the pusher to move forward by the elastic force of the spring 14, so that the push rod 17 of the pusher quickly pushes the blood collection needle forward, making the blood collection needle pierce into the arm of the blood collection person, facilitating the blood collection operation of the blood collection personnel.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
