[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] The utility model provides a portable fingertip blood collection and aspiration integrated blood sampling device, see Figures 1 to 4 , mainly includes a shell 1, a rubber airbag 2, a blood suction tube 10 and a needle 8.

[0036] The shell 1 is the main structure of the entire blood collection and suction device. A plurality of balls 3 are arranged in a ring at the bottom, which are used to massage the fingertip skin area to be drawn before blood collection. The rubber airbag 2 is arranged inside the shell 1, and can be pressed downward and moved during blood collection. The suction blood tube 10 is connected to the top of the rubber airbag 2 and extends out of the top of the shell 1. The needle 8 is fixedly arranged at the bottom of the rubber airbag 2, and can extend out of the bottom of the shell 1 as the rubber airbag 2 is pressed downward and moved during blood collection. The portable fingertip blood collection and suction integrated blood collector provided by the utility model drives the needle 8 to be inserted into the fingertip skin tissue by pressing the rubber airbag 2. After puncture, the shell 1 can be inverted so that the suction blood tube 10 is located at the puncture site, and the rubber airbag 2 is pressed. This method can use a rubber-tipped dropper-like method to suck out blood, so as to achieve the collection function. It is integrated and easy to operate. The utility model solves the problem of inconvenient operation caused by many tools required in the process of collecting blood from fingertips, and at the same time, the massage and kneading of the fingertip skin by the ball is conducive to blood flow, which can speed up the blood collection process.

[0037] See also Figures 1 to 3 The outer shell 1 is made of a hard material, cylindrical in shape, and hollow inside, and is used to accommodate the rubber airbag 2, the needle 8 and other components. The rubber airbag 2 is also cylindrical in shape, and its size is slightly smaller than the inner hollow part of the outer shell 1, so as to ensure that the rubber airbag 2 and the needle 8 can be completely included in the inner part of the outer shell 1.

[0038] See also Figure 2 The bottom of the housing 1 is provided with a through hole 1, and the periphery of the through hole 1 is fixedly connected with a protective tube 4. When not in use, the tip of the needle 8 is located in the protective tube 4.

[0039] It should be noted that the length of the protective tube 4 should not be too long, so as to ensure that when in use, the needle 8 can pass through the protective tube 4 and pierce the fingertip skin tissue when the needle 8 is moved downward by the rubber airbag 2. When not in use, the needle tip of the needle 8 can be stored by the protective tube 4 to prevent the needle tip of the needle 8 from being exposed and injuring people.

[0040] See also Figure 1 , Figure 3 A through hole 2 is provided on the top of the shell 1 , a sleeve 11 is fixedly connected to the outer periphery of the through hole 2, and the blood suction tube 10 is slidably inserted into the sleeve 11 .

[0041] The sleeve 11 is a cylindrical hollow body. To ensure safety, the hollow inner diameter of the sleeve 11 is slightly larger than the outer diameter of the blood suction tube 10, so that the blood suction tube 10 can be slidably inserted into the sleeve 11. The sleeve 11 can maintain the stable movement of the blood suction tube 10. When the rubber airbag 2 moves up and down, the blood suction tube 10 slides and moves up and down in the sleeve 11.

[0042] Continue to see Figure 1 , Figure 3The two opposite side walls of the housing 1 are provided with openings 5, and the outer wall of the rubber airbag 2 is partially exposed through the housing openings 5. When in use, the exposed part of the rubber airbag 2 is pressed through the openings 5 ​​to move the rubber airbag 2 downward to achieve needle puncture. It can be seen that the openings 5 ​​can facilitate medical personnel to operate the rubber airbag 2 up and down or squeeze the rubber airbag 2.

[0043] See also Figures 1 to 3 The two side walls of the housing 1 are symmetrically provided with an anti-skid layer 6, which is composed of a plurality of parallel anti-skid convex strips. The anti-skid convex strips can increase the friction resistance between the hands of medical staff and the housing 1, thereby preventing the device from slipping when used, improving the convenience of operation and the safety of the device.

[0044] Continue to see Figure 1 , Figure 2 , Figure 4 The two side walls of the rubber airbag 2 exposed through the opening 5 are symmetrically provided with an anti-skid layer 2 9, which is also composed of a plurality of parallel anti-skid convex strips. When the medical staff slides up and down or squeezes the rubber airbag 2, the anti-skid convex strips can increase the friction resistance between the medical staff's hands and the rubber airbag 2, making the operation easier.

[0045] See also Figure 2 , multiple balls 3 are evenly distributed in an annular shape around the outer circumference of the protective tube 4 at the bottom of the housing 1. Usually, for convenience and practicality, multiple balls 3 are provided, for example, 4-6 balls 3 are closely arranged and of equal size. The balls 3 can roll at the bottom of the housing 1. Medical staff can control the rolling of the balls 3 through the housing 1, and massage the fingertip skin with a little force. Massage after puncture increases blood circulation and facilitates blood outflow.

[0046] See also Figure 1 , Figure 4 The utility model provides a portable fingertip blood collection and aspiration integrated blood collector, which also includes a spring 7. The spring 7 is sleeved on the periphery of the needle 8. The head of the spring 7 is fixedly connected to the bottom of the rubber airbag 2, and the tail of the spring 7 is fixedly connected to the bottom inner wall of the shell 1. The automatic rebound of the rubber airbag 2 can be controlled by the spring 7. The spring 7 is retractable, and when the rubber airbag 2 is pressed, the smooth retracting movement of the needle 8 can be maintained. The elastic force of the spring 7 can also reset the rubber airbag 2, so that the needle 8 is upwardly retracted into the protective tube 4 provided in the shell 1, so that the needle 8 can be automatically stored, so as to avoid the used needle from being exposed after the operation is completed, and to avoid accidental operation and injury to people, causing unsafe medical accidents.

[0047] The working principle of the utility model is as follows: when collecting blood, the medical staff operates the shell 1 to make the shell 1 drive the ball 3 to roll on the fingertips, and with a little force, the blood collection area can be massaged and kneaded to increase the local blood circulation speed. After the massage is completed, the rubber airbag 2 is pressed down again. The rubber airbag 2 is hard rubber and has anti-skid patterns on the surface. The rubber airbag 2 is pressed down, and the rubber airbag 2 drives the needle 8 to move downward, and drives the spring 7 to undergo elastic deformation, so that the needle 8 punctures into the skin tissue of the fingertips, and then the elastic force of the spring 7 drives the rubber airbag 2 to reset, so that the needle 8 resets upward and is collected in the protective tube 4. At this time, the fingertip puncture area is massaged by rolling the ball 3 of the shell 1, and then the shell 1 is inverted so that the blood suction tube 10 is located in the puncture area, and the rubber airbag 2 is pressed so that the rubber airbag 2 can collect blood in a manner similar to a rubber-tipped dropper.

[0048] The utility model realizes the integrated design of the fingertip blood collection device, is easy to operate, safe to use, and is suitable for collecting fingertip blood in various medical occasions.

[0049] Although several specific implementation details are included in the above discussion, these should not be interpreted as limiting the scope of the present invention. Certain features described in the context of a separate embodiment may also be implemented in a single implementation in combination. On the contrary, the various features described in the context of a single implementation may also be implemented in multiple implementations individually or in any suitable sub-combination.

[0050] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
