One end of the rubber hose in the blood sample dilution chamber is connected to a quantitative capillary tube made of glass with an inner diameter of 1 mm.
[0021] The working principle and operation method of the present invention are:
[0022] The medical worker places the unused matching blood collection tubes on the matching blood collection tube carrier, checks whether the reagents in the disinfection alcohol barrel and the diluent barrel are sufficient, and then turns on the machine. The person whose blood is being collected enters the corresponding information on the multimedia interactive device and clicks to start blood collection. The blood collection terminal limit device moves from the limit device moving platform to above the blood collection terminal blood collection hole of the blood collection terminal support plate.
[0023] After the blood sampling distal limit device is in place, the matching blood sampling tube loading device first pushes an unused matching blood sampling tube to the front end of the matching blood sampling tube carrier for unsampled blood, and then returns to the initial position. The matching blood sampling tube transverse movement device then pushes the unused matching blood sampling tube located at the front end of the matching blood sampling tube carrier for unsampled blood to the bottom of the disinfectant alcohol injection hole, and then the disinfectant alcohol injection pump injects a certain amount of disinfectant alcohol into the disinfectant sponge pad of the unused matching blood sampling tube. After the disinfectant alcohol is injected, the matching blood sampling tube transverse movement device continues to move the matching blood sampling tube that has been injected with disinfectant alcohol to the matching blood sampling tube rotating lifting device, and the matching blood sampling tube base pressure sensor on the matching blood sampling tube rotating lifting device senses and confirms that the matching blood sampling tube is in place.
[0024] After the matching blood collection tube is in place, the multimedia interactive device switches to standby mode and plays blood collection reminders. The person whose blood is being collected directly puts his palm into the blood collection tip limiter and presses on the blood collection hole of the blood collection tip. The blood collection tip presses the matching blood collection tube to trigger the heavy sensing of the pressure sensor at the base of the matching blood collection tube, confirming that the blood collection tip of the palm is in place. The multimedia interactive device starts playing multimedia videos, and the blood collection tip limiter starts to inject gas and pressurize, limiting the range of movement of the blood collection tip. The matching blood collection tube rotary lifting device drives the matching blood collection tube to rotate 15° forward and backward twice continuously, so that the disinfection sponge pad can disinfect the blood collection tip.
[0025] After the blood sampling tip is disinfected, the matching blood sampling tube rotary lifting device drives the matching blood sampling tube to rotate 45° clockwise, and drives the disposable puncture device to puncture the blood sampling tip and then retract. After the blood sampling tip is punctured, the matching blood sampling tube rotary lifting device drives the matching blood sampling tube to rotate 45° clockwise to connect to the blood sample collection chamber, and the negative pressure of the peristaltic pump is used to simulate the squeezing of the punctured blood sampling tip to make it bleed, thereby collecting the blood sample into the blood sample collection chamber. After the blood sample is collected, the blood sampling tip limiting device deflates and releases pressure, and retreats from the blood sampling tip blood sampling hole of the blood sampling tip support plate to the moving platform of the limiting device, and the multimedia interactive device prompts the person whose blood is being collected to remove his palm. At any time before this, if the blood sampling tip of the blood sampling tip of the person whose blood is being collected moves away from the blood sampling hole of the blood sampling tip, the blood collection work will be suspended immediately.
[0026] After the palm is removed, the pressure sensor at the tip of the matching blood collection tube on the top of the matching blood collection tube disappears, and the pressure sensor at the base of the matching blood collection tube on the matching blood collection tube rotary lifting device also disappears. The matching blood collection tube rotary lifting device is connected to the hose clamping and cutting device, and drives the matching blood collection tube rotary lifting device to open the rubber hose. The quantitative capillary is connected to the capillary connecting tube, and the quantitative capillary absorbs a certain amount of blood sample in the blood sample collection cavity through the capillary connecting tube and the rubber hose in turn. After the blood sample is absorbed, the matching blood collection tube rotary lifting device continues to drive the hose clamping and cutting device to cut off the rubber hose, and the air pump starts to work, pressurizes the hose clamping and cutting cavity, and injects the blood sample in the quantitative capillary into the blood sample dilution cavity of the matching blood collection tube. The air pump stops working, and the matching blood collection tube rotary lifting device drives the hose clamping and cutting device to return downward.
[0027] After the blood sample is injected, the matching blood collection tube lateral movement device continues to push the matching blood collection tube that has been collected to the bottom of the diluent injection hole, and the diluent injection pump injects a certain amount of diluent into the blood sample dilution chamber. At the same time, the matching blood collection tube rotary lifting device rotates 135° counterclockwise to return to its original position. After the diluent is injected, the matching blood collection tube lateral movement device pushes the diluted matching blood collection tube to the front end of the matching blood collection tube carrier that has been collected, and then returns to the initial position. Then the matching blood collection tube unloading device pushes the used matching blood collection tube to the rear end of the matching blood collection tube carrier that has been collected, and then returns to the initial position, thereby completing a peripheral blood collection work.
[0028] All stepper motors, gas injection tubes, air pumps, peristaltic pumps and multimedia interactive devices on the automated peripheral blood collection and pre-dilution machine of the present invention are controlled by an integrated controller with PLC as the core. The integrated controller coordinates the work of all stepper motors, gas injection tubes, air pumps, peristaltic pumps and multimedia interactive devices according to a pre-set logic program and a pressure sensing signal received during the blood collection process, thereby ensuring the smooth completion of blood collection and dilution work.
[0029] The beneficial effects of the present invention are:
[0030] The automated peripheral blood collection and pre-dilution machine of the present invention can be used in conjunction with a dedicated matching blood collection tube to automatically complete the tasks of peripheral site disinfection, puncture, blood sample collection, and quantitative dilution of blood samples, greatly reducing the labor intensity of medical workers and reducing manual operation errors to a certain extent.
[0031] The matching blood collection tube loading device, matching blood collection tube lateral movement device and matching blood collection tube unloading device on the automated peripheral blood collection and pre-dilution machine of the present invention can automatically and accurately complete the matching blood collection tube loading positioning, disinfection alcohol sample addition hole positioning, peripheral blood collection hole positioning, diluent sample addition hole positioning and unloading positioning, thereby greatly improving the efficiency and accuracy of peripheral blood sample collection.
[0032] The airbag type blood sampling peripheral limiting device on the automated peripheral blood collection and pre-dilution machine of the present invention can not only protectively limit the movement of the blood sampling peripheral of the blood sampling subject to a certain extent during the blood sampling process to ensure the smooth completion of the blood collection work, but also can play a certain shielding role on the blood sampling peripheral to reduce the fear of the blood sampling subject, especially the underage blood sampling subject.
[0033] The multimedia interactive device on the automated peripheral blood collection and pre-dilution machine of the present invention not only allows the blood collection subject to input corresponding information and provide prompts for the blood collection process, but also plays multimedia content that can easily divert the blood collection subject's attention during the blood collection process, so as to further ensure that the blood collection work is completed smoothly.
[0034] The size of the matching blood collection tube of the present invention can be designed into various specifications based on the anthropological basis and the age of the blood sampler, and the disinfection sponge pad, the disposable spring puncture needle device, the blood sample collection chamber, the hose clamp spring and the cutting blade device and the blood sample dilution chamber are integrated on a tube body, and the five functional areas are separately separated, which saves the space required for blood collection and avoids cross infection.
[0035] The matching blood collection tube rotary lifting device on the automated peripheral blood collection and pre-dilution machine of the present invention can automatically and accurately cooperate with the matching blood collection tube to complete the tasks of wiping with disinfectant alcohol, firing of the disposable spring puncture needle device, intermittent negative pressure blood collection by the peristaltic pump, opening and cutting of the rubber hose, and gas injection and pressurization by the air pump, thereby ensuring that the blood collection work is completed smoothly.
[0036] The matching blood collection tube rotary lifting device on the automated peripheral blood collection and pre-dilution machine of the present invention adopts peristalsis to collect blood from the periphery. During the blood sample collection process, the intermittent negative pressure generated by the peristaltic pump can produce a certain degree of squeezing effect on the blood collection periphery, thereby ensuring the rapid completion of the blood sample collection work and reducing the pain of the person whose blood is being collected.
[0037] The matching blood collection tube rotating lifting device on the automated peripheral blood collection and pre-dilution machine of the present invention also adopts a pressure sensing device, which can ensure that once the blood collection tip is removed during the blood collection process, the blood collection work can be quickly paused, and the blood collection tip limiting device can be removed at the same time to release the blood collection tip, so as to avoid blood collection failure or accidents.

[0071] After the blood sampling terminal limit device is in place, the loading push rod longitudinal movement stepper motor 25 drives the loading push rod 28 to move forward with the cooperation of the loading push rod longitudinal movement screw rod 24, and then pushes an unused matching blood sampling tube B to the front end of the matching blood sampling tube carrier 10 without blood sampling, and the loading push rod telescopic stepper motor 27 drives the loading push rod 28 to retract to the left, so that the right end arc-shaped bent rod of the loading push rod 28 exits the longitudinal movement area of the unused matching blood sampling tube B, and the loading push rod longitudinal movement stepper motor 25 again drives the loading push rod 28 to move backward to the initial position with the cooperation of the loading push rod longitudinal movement screw rod 24, and the loading push rod telescopic stepper motor 27 drives the loading push rod 28 to extend to the right again, so that the right end arc-shaped bent rod of the loading push rod 28 enters the longitudinal movement area of the unused matching blood sampling tube B again, waiting for the next loading.
[0072] The lateral movement stepping motor 35 of the lateral movement push rod, in cooperation with the lateral movement screw rod 34 of the lateral movement push rod, first drives the lateral push rod 38 to move a certain distance to the right, and then pushes the unused matching blood collection tube B located at the front end of the matching blood collection tube carrier 10 for uncollected blood along the left slide 12 to the bottom of the disinfection alcohol sampling hole 4. At this time, the disinfection sponge pad 61 of the unused matching blood collection tube B is located directly below the disinfection alcohol sampling hole 4, and the disinfection alcohol barrel 6 injects a certain amount of disinfection alcohol into the disinfection sponge pad 61 on the disinfection area C1 of the unused matching blood collection tube B through the disinfection alcohol sampling pump 5.
[0073] After the injection of disinfecting alcohol is completed, the lateral movement stepping motor 35 of the lateral push rod continues to drive the lateral push rod 38 to move a certain distance to the right with the cooperation of the lateral movement screw rod 34 of the lateral push rod, and then pushes the matching blood collection tube B injected with disinfecting alcohol out of the left slide 12 and moves it to the matching blood collection tube rotating lifting device A, so that the matching blood collection tube slot 57 at the lower part of the matching blood collection tube B is embedded with the matching blood collection tube base clamping strip 43 at the top of the matching blood collection tube rotating lifting device A, and the matching blood collection tube positioning clamping columns 59 on both sides of the matching blood collection tube base clamping strip 43 are also embedded in the matching blood collection tube base positioning clamping holes 45 on both sides of the matching blood collection tube slot 57. At the same time, the matching blood collection tube pressure transmission device 58 on the matching blood collection tube slot 57 contacts the matching blood collection tube base pressure sensor 44 on the matching blood collection tube base clamping strip 43, and the matching blood collection tube base pressure sensor 44 triggers a slight induction to confirm that the matching blood collection tube B is in place. At this time, the top ends of the puncture firing rod 46, the peristaltic pump connecting rod 47 and the hose clamping and cutting device control rod 48 on the matching blood collection tube rotating lifting device A are respectively aligned with the puncture firing rod insertion hole 63, the peristaltic pump connecting rod insertion hole 70 and the hose clamping and cutting device control rod insertion hole 74 at the bottom of the matching blood collection tube B.
[0074] After the matching blood collection tube B is in place, the multimedia interactive device 23 switches to the standby state and plays the blood collection reminder. The adult blood collection subject directly extends the palm into the blood collection tip limiting device and places the palm on the blood collection tip blood collection hole 3 of the blood collection tip supporting plate 2. The minor blood collection subject has the palm held by an adult and then extends the palm into the blood collection tip limiting device and presses the palm on the blood collection tip blood collection hole 3 of the blood collection tip supporting plate 2. After the palm is placed on the blood collection tip blood collection hole 3, the blood collection tip of the palm is pressed against the matching blood collection tube tip pressure sensor 56 at the top of the matching blood collection tube B, and the matching blood collection tube tip pressure sensor 56 triggers the induction, and the matching blood collection tube base pressure sensor 44 is triggered through the matching blood collection tube pressure transmission device 58 at the bottom of the matching blood collection tube B to trigger the heavy induction, confirming that the blood collection tip of the palm is in place.
[0075] After the blood sampling tip is in place, the multimedia interactive device 23 starts playing multimedia videos, and the air injection pipe 20 of the limiting device starts to inject air and pressurize the upper airbag plate 15, the left airbag plate 16 and the right airbag plate 17 of the blood sampling tip limiting device to limit the range of motion of the palm inserted into the blood sampling tip limiting device. The matching blood sampling tube base rotating motor 39 drives the matching blood sampling tube B to rotate 15° forward and backward twice continuously through the matching blood sampling tube base, so that the disinfection sponge pad 61 on the matching blood sampling tube B can disinfect the blood sampling tip.
[0076] After the blood sampling tip is disinfected, the matching blood sampling tube base rotating motor 39 drives the matching blood sampling tube B to rotate 45 degrees clockwise through the matching blood sampling tube base, so that the disposable puncture device on the matching blood sampling tube B is aligned with the newly disinfected blood sampling tip. The puncture device vertical movement stepping motor 49, in cooperation with the puncture firing rod 46, quickly drives the puncture needle push rod 64 to push up and return to its position, thereby allowing the disposable puncture needle 66 to quickly move along the disposable puncture device vertical movement cavity to puncture the blood sampling tip, and automatically retract under the restoring force of the disposable puncture needle return spring 67.
[0077] After the blood sampling tip is punctured, the matching blood sampling tube base rotating motor 39 drives the matching blood sampling tube B to rotate 45° clockwise through the matching blood sampling tube base, so that the blood sample collection chamber 68 on the matching blood sampling tube B is aligned with the punctured blood sampling tip. The peristaltic pump connecting rod vertical movement stepper motor 52 drives the peristaltic pump connecting rod 47 to push up, so that the top end of the peristaltic pump connecting rod 47 extends into the peristaltic pump connecting rod insertion hole 70 and communicates with the peristaltic pump connecting chamber, and is sealed by the peristaltic pump connecting pipe sealing ring 51 at the top of the peristaltic pump connecting rod 47. The peristaltic pump 50 starts to work, and the peristaltic pump 50 sequentially applies negative pressure to the blood sample collection chamber 68 through the hollow rod part in the peristaltic pump connecting rod 47, the peristaltic pump connecting chamber and the peristaltic pump negative pressure hole 71, so as to simulate squeezing the punctured blood sampling tip to make it bleed, thereby collecting the blood sample into the blood sample collection chamber 68. The peristaltic pump connecting rod vertical movement stepper motor 52 drives the peristaltic pump connecting rod 47 to return downward, so that the top end of the peristaltic pump connecting rod 47 exits the peristaltic pump connecting rod penetration hole 70 and is separated from the peristaltic pump connecting cavity.
[0078] After the blood sample is collected, the air injection tube 20 of the limiting device begins to deflate and release the upper airbag plate 15, the left airbag plate 16 and the right airbag plate 17 of the blood sampling terminal limiting device. The limiting device longitudinal moving stepper motor 21 drives the blood sampling terminal limiting device to move backwards in cooperation with the limiting device longitudinal moving screw 19, and returns to the limiting device moving platform 1 from above the blood sampling terminal blood sampling hole 3 of the blood sampling terminal support plate 2, and the multimedia interactive device 23 prompts the blood sampling person to remove the palm. Before the multimedia interactive device 23 prompts that the palm of the blood sampling person is removed from the blood sampling terminal blood sampling hole 3, the blood sampling work is immediately suspended, and the prompt of the instrument suspension is displayed on the multimedia interactive device 23. At the same time, the blood sampling terminal limiting device deflates and releases pressure in advance and moves backwards to release the palm.
[0079] After the palm is removed, the sensing of the matching blood collection tube tip pressure sensor 56 on the top of the matching blood collection tube B disappears, and the hose clamping and cutting device vertical moving stepping motor 54 drives the hose clamping and cutting device control rod 48 to push up, so that the top end of the hose clamping and cutting device control rod 48 extends into the hose clamping and cutting device control rod insertion hole 74 and docks with the lower end of the hose clamping and cutting device push rod 73 located in the hose clamping and cutting device vertical moving cavity, and continues to drive the hose clamping and cutting device push rod 73 to rise to the first position height, and pushes open the hose clamping spring 77 at the top of the hose clamping and cutting device push rod 73 for clamping the rubber hose 81. After the hose clamping spring 77 is pushed open, the rubber hose 81 is opened, and the quantitative capillary 82 is connected with the capillary connecting tube 78. The quantitative capillary 82 absorbs a certain amount of blood sample in the blood sample collection cavity 68 through the capillary connecting tube 78 and the rubber hose 81 in sequence. After the blood sample is absorbed, the vertical moving stepper motor 54 of the hose clamping and cutting device continues to drive the hose clamping and cutting device control rod 48 to push up, and further raises the hose clamping and cutting device push rod 73 to the second position height, so that the hose cutting blade 76 at the top of the hose clamping and cutting device push rod 73 cuts the rubber hose 81. After the rubber hose 81 is cut, the air pump 53 starts to work, and the air pump 53 pressurizes the hose clamping and cutting cavity 72 through the hollow rod part in the hose clamping and cutting device control rod 48, the air pump positive pressure connection air hole 75 on the lower surface of the hose clamping and cutting device push rod 73, the air pump air supply passage inside the hose clamping and cutting device push rod 73, and the air pump positive pressure outlet hole 79 on the upper surface of the hose clamping and cutting device push rod 73, and injects the blood sample in the quantitative capillary 82 into the blood sample dilution cavity 80 of the matching blood collection tube B. The air pump 53 stops working, and the vertical moving stepping motor 54 of the hose clamping and cutting device drives the hose clamping and cutting device control rod 48 to return downward, so that the top end of the hose clamping and cutting device control rod 48 exits the air pump positive pressure connection air hole 75 on the lower surface of the hose clamping and cutting device push rod 73, and disengages from the vertical moving cavity of the hose clamping and cutting device.
[0080] After the blood sample is injected, the lateral push rod lateral movement stepper motor 35 continues to drive the lateral push rod 38 to move a certain distance to the right under the cooperation of the lateral push rod lateral movement screw rod 34, and then pushes the blood sampling tube B along the right slide 13 to the bottom of the diluent injection hole 7. At this time, the blood sample dilution chamber 80 of the blood sampling tube B is located directly below the diluent injection hole 7, and the diluent barrel 9 injects a certain amount of diluent into the blood sample dilution chamber 80 through the diluent injection pump 8. At the same time, the matching blood sampling tube base rotation motor 39 drives the matching blood sampling tube base to rotate 135° counterclockwise to return to its original position, waiting for the next blood sampling operation.
[0081] After the diluent is injected, the lateral push rod lateral movement stepping motor 35 continues to drive the lateral push rod 38 to move a certain distance to the right under the cooperation of the lateral push rod lateral movement screw rod 34, and then pushes the diluted matching blood collection tube B along the right slide 13 to the front end of the matching blood collection tube carrier 11. The lateral push rod telescopic stepping motor 37 drives the lateral push rod 38 to retract to the front side, so that the rear end arc-shaped curved rod of the lateral push rod 38 exits the lateral movement area of the diluted matching blood collection tube B, and the lateral push rod lateral movement stepping motor 35 again drives the lateral push rod 38 to move to the left to the initial position under the cooperation of the lateral push rod lateral movement screw rod 34, and the lateral push rod telescopic stepping motor 37 drives the lateral push rod 38 to extend to the rear side, so that the rear end arc-shaped curved rod of the lateral push rod 38 enters the lateral movement area of the unused matching blood collection tube B again, waiting for the next lateral transportation.
[0082] The stepping motor 30 for longitudinal movement of the material discharge push rod drives the material discharge push rod 33 to move backward with the cooperation of the longitudinal movement screw rod 29, and then pushes the used matching blood collection tube B to the rear end of the matching blood collection tube carrier 11. The telescopic stepping motor 32 for the material discharge push rod drives the material discharge push rod 33 to retract to the right, so that the arc-shaped bent rod at the left end of the material discharge push rod 33 withdraws from the longitudinal movement area of the used matching blood collection tube B. The stepping motor 30 for longitudinal movement of the material discharge push rod drives the material discharge push rod 33 to move forward to the initial position again with the cooperation of the longitudinal movement screw rod 29. The telescopic stepping motor 32 for the material discharge push rod drives the material discharge push rod 33 to extend to the left, so that the arc-shaped bent rod at the left end of the material discharge push rod 33 extends into the longitudinal movement area of the used matching blood collection tube B again, waiting for the next material discharge.
