Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an upper arm blood vessel blocking device for convenient blood collection. Background Art

[0002] When patients visit the hospital for treatment, they often need to collect blood samples for testing. Currently, most of the blood is collected from the median cubital vein. The standard steps for collecting blood from the median cubital vein are: first help the patient to position himself, expose his elbow, straighten his arm, and palm up, then select the puncture site, generally the median cubital vein, determine the puncture point, which is usually located 2 horizontal fingers below the cubital fossa, and disinfect the skin at the blood collection site. The operator wears gloves, takes out the blood collection needle, holds the blood collection needle at an angle of 15 to 30° to the skin, inserts the needle obliquely, and inserts the blood collection needle into the vein. After seeing the blood return, fix the needle, collect blood to the required amount, and after the blood collection is completed, quickly pull out the blood collection needle and press the puncture site with a dry cotton swab for 5 to 10 minutes until the bleeding stops completely. When collecting blood from the median cubital vein, the operator must pay attention to strictly implement aseptic operation to avoid infection.

[0003] At present, the way to block the blood vessels in the upper limbs during blood collection is to tie and fix the upper limbs with rubber bands to block the venous return, and then fill the blood vessels, which is conducive to puncture. At present, the rubber band needs to be replaced once for each patient. In order to avoid cross-infection of blood, the current method of tying and replacing the fixing band is more troublesome and inefficient. The rubber fixing band needs to be soaked and disinfected and air-dried, and the disinfection process is more cumbersome. Utility Model Content

[0018] The present invention is further described in detail below in conjunction with the embodiments.

[0019] like Figure 1-3 As shown, a specific embodiment of an upper arm blood vessel blocking device for convenient blood collection provided by the utility model is as follows:

[0020] An upper arm blood vessel blocking device for convenient blood collection comprises a base 1 and a disinfectant supply bin 2, wherein an inclined support plate 3 is provided on the base 1, and two groups of blood vessel blocking blood collection mechanisms 4 are installed on the inclined support plate 3, wherein one group of blood vessel blocking blood collection mechanisms 4 is in a standby state;

[0021] The blood vessel blocking blood sampling mechanism 4 includes a blood vessel blocking cylinder 5, which is installed on the diagonal support plate 3. The cylinder wall of the blood vessel blocking cylinder 5 has an installation cavity. Two annular tracks 6 are installed on the inner wall of the blood vessel blocking cylinder 5. The two annular tracks 6 are closely adjacent to each other. Two slides 7 are arranged on each annular track 6. The two slides 7 can slide along the annular track 6. The outer arc of the annular track 6 is located in the installation cavity. The outer arc of the annular track 6 is a gear ring structure 8. One end of the slide 7 is located in the installation cavity. A pinion 9 is rotatably installed on one end of the slide 7. The pinion 9 is meshed with the gear ring structure 8. A forward and reverse motor 10 is also provided on the slide 7. The forward and reverse motor 10 drives the pinion 9 to rotate. An elastic belt 11 is connected between the ends of the two slides 7 of the annular track 6. The forward and reverse motor 10 can drive the slide 7 to move around the annular track 6 through the meshing transmission of the pinion 9 and the gear ring structure 8;

[0022] A plurality of disinfection spray nozzles 12 are arranged on the inner wall of the front end and the rear end of the blood vessel blocking tube 5, and the disinfection spray nozzles 12 face the middle position inside the blood vessel blocking tube 5. The disinfection liquid supply bin 2 is connected to a disinfection pump, and the disinfection pump is connected to all the disinfection spray nozzles 12 through a hose. A cover plate 13 is arranged on the front end and the rear end of the blood vessel blocking tube 5, and the cover plate 13 is used to block the front end and the rear end of the blood vessel blocking tube 5, and the cover plate 13 is hinged to the end of the blood vessel blocking tube 5 through a pin shaft;

[0024] In the upper arm blood vessel blocking device of this embodiment, the blood vessel blocking cylinder 5 is a hollow cylindrical structure. When blood is collected, the inside of the blood vessel blocking cylinder 5 is first disinfected, and the front and rear openings of the blood vessel blocking cylinder 5 are blocked by the cover plate 13. The disinfectant supply bin 2 is filled with alcohol disinfectant. The disinfection control switch 15 is pressed, and the main controller controls the disinfection pump to start. The disinfection pump transports the disinfectant in the disinfectant supply bin 2 to the disinfection spray nozzle 12 through a hose, and the disinfection spray nozzle 12 sprays a mist of disinfectant toward the inside of the blood vessel blocking cylinder 5 to seal and disinfect the inside;

[0025] After the disinfection is completed, the patient's arm is inserted into the blood vessel blocking tube 5. In the initial state, the arm is located between the two elastic bands 11. Then the motor control switch 16 is pressed, and the main controller controls all the forward and reverse motors 10 to move. The forward and reverse motors 10 on the same circular track 6 rotate in opposite directions, so that the two slides 7 on the same circular track 6 move in opposite directions. Driven by the slides 7, the elastic bands 11 move, as shown in FIG. Figure 2 and Figure 3 As shown, for example, the elastic band 11 on the left side of the arm starts to move to the right, and the elastic band 11 on the right side of the arm starts to move to the left, and the two elastic bands 11 tighten the arm together to stop bleeding, and then the blood collection operation can be performed. After the blood collection is completed, the main controller controls the forward and reverse motor 10 to reverse and return to the initial state.
