Description

Technical Field

[0001] The utility model relates to the technical field of hematology nursing, in particular to an intravenous chemotherapy device used in hematology. Background Art

[0002] Hematology mainly deals with blood-related diseases, such as anemia (iron deficiency anemia, aplastic anemia, megaloblastic anemia, acute hemorrhagic anemia, thalassemia and hemolytic anemia), white blood cell diseases, etc.

[0003] In the prior art, the patent with the authorization publication number CN 216653031 U discloses an intravenous chemotherapy device for hematology nursing, which uses an electric push rod to squeeze and fix the syringe, and then pushes the syringe through a push plate to get a piston rod for intravenous injection. However, when using it, if the syringe is to be effectively fixed to prevent the syringe from sliding, the electric push rod needs to be tightly squeezed on the outside of the syringe. At this time, the syringe will be deformed inwardly due to the pressure of the electric push rod. When the internal piston is pushed to the deformed position, it is blocked by the deformed position and the pushing is affected. At the same time, in the prior art, the patent with the authorization publication number CN 216653031 U discloses an intravenous chemotherapy device for hematology nursing, which uses an electric push rod to squeeze and fix the syringe, and then pushes the syringe through a push plate to get a piston rod for intravenous injection. However, when using it, if the syringe is to be effectively fixed to prevent the syringe from sliding, the electric push rod needs to be tightly squeezed on the outside of the syringe. At this time, the syringe will be deformed inwardly due to the pressure of the electric push rod. When the internal piston is pushed to the deformed position, it is blocked by the deformed position and the pushing is affected. Patent No. 219681324U discloses an intravenous chemotherapy device for hematology nursing. Its background technology discloses that currently hematology chemotherapy drugs are generally administered via intravenous injection. Existing hematology chemotherapy drugs sometimes need to be protected from light during nursing or injection. This is because light exposure will further accelerate the oxidation of the drugs.

The injection syringe is a transparent structure with light transmittance, but the patent with authorization publication number CN 216653031 U cannot shield the syringe from light, which can easily lead to medical risks.

The clamping mechanism 4 has two groups, and the two groups of clamping boxes 4 are symmetrically arranged front and back. The clamping box 4 clamps the pressing circular plate on the syringe, and the power switch 2 is electrically connected to an external power supply.

[0023] The clamping mechanism 7 includes a fastener 71 and a positioning groove 72. The fastener 71 is fixed to the side of the syringe placement rack 1, and the positioning groove 72 is opened on the side of the light shield 8. The fastener 71 is clamped with the positioning groove 72 to place the syringe on the syringe placement rack 1. The wing plate on the syringe is clamped through the wing plate clamping groove 6 on the syringe placement rack 1. The fastener 71 is clamped with the positioning groove 72 to clamp the light shield 8 above the syringe placement rack 1. The syringe is covered with light by the light shield 8, and the wing plate clamping groove 6 on the light shield 8 is clamped with the syringe wing plate. After the installation is completed, the inner surface of the light shield 8 does not touch the syringe. The syringe surface is in contact with the syringe, and it only fixes the syringe wing plate to prevent the syringe from being deformed by pressure and affecting the pushing of the piston rod, thereby ensuring that the injection operation can be carried out smoothly. The syringe wing plate is doubly clamped through the wing plate slot 6 on the syringe placement rack 1 and the wing plate slot 6 on the light shield 8, and is firmly fixed, avoiding the risk of the syringe falling off due to the upper part of the half syringe wing plate being unshielded when being clamped. At the same time, after blocking the light, the drug is extracted through the syringe, and the syringe is covered with light shielding by the light shielding cover 8 to avoid the drug being exposed to light and having adverse effects, thereby ensuring the safety of treatment.

[0024] The driving mechanism 5 includes a servo motor 51 and a screw rod 54. The screw rod 54 is rotatably installed in the base installation cavity of the syringe placement rack 1. The servo motor 51 is installed at the end of the syringe placement rack 1. The output shaft of the servo motor 51 is fixedly connected to the end of the screw rod 54. The servo motor 51 is electrically connected to the power switch 2. The driving mechanism 5 also includes a transmission nut 53, a sliding seat 52 and a slide groove 55. The slide groove 55 is opened on the base of the syringe placement rack 1. The sliding seat 52 is slidably connected to the slide groove 55. The transmission nut 53 is fixed on the sliding seat 52 and is connected to the screw rod 54. The rod 54 is threadedly connected, and the clamping mechanism 3 is arranged on the support of the sliding seat 52. The output shaft of the servo motor 51 drives the screw rod 54 to rotate. The screw rod 54 and the transmission nut 53 are threadedly transmitted. The transmission nut 53 drives the sliding seat 52 to slide along the slide groove 55. The sliding seat 52 drives the slot box 4 to move through the clamping mechanism 3. The slot box 4 drives the syringe pressing circular plate to move. The syringe pressing circular plate pushes the syringe piston to move. It first extracts the intravenous chemotherapy drugs, and then injects the intravenous chemotherapy drugs, ensuring the rationality of the design.

The spring 32 is sleeved on the movable rod 31. The ends of the spring 32 are respectively fixedly connected to the support of the sliding seat 52 and the slot box 4. The clamping mechanism 3 also includes a handle 33. The handle 33 is fixed to the outer end of the movable rod 31. The handle 33 is pulled by hand, and the handle 33 pulls the two groups of slot boxes 4 away from each other through the movable rod 31, thereby reserving a placement position for the syringe pressing circular plate. At this time, the spring 32 is compressed and deformed, and the deformation force of the spring 32 reacts on the slot box 4. When the handle 33 is released, the spring 32 returns to its original position, thereby driving the slot box 4 to return to its original position, and the two sides of the syringe pressing circular plate are clamped through the two slot boxes 4. By clamping the two sides of the syringe pressing circular plate, it makes it more stable when the syringe pressing circular plate is pulled out.

[0026] The working principle of the intravenous chemotherapy device for hematology provided by the utility model is as follows: a syringe is placed on a syringe placement rack 1, and the wing plate on the syringe is clamped through the wing plate clamping groove 6 on the syringe placement rack 1, and the handle 33 is toggled by hand, and the handle 33 pulls the two groups of clamping slot boxes 4 away from each other through the active rod 31, thereby reserving a placement position for the syringe pressing circular plate. At this time, the spring 32 is compressed and deformed, and the deformation force of the spring 32 reacts on the clamping slot box 4. When the handle 33 is released, the spring 32 returns to its original position, thereby driving the clamping slot box 4 to return to its original position, and the two sides of the syringe pressing circular plate are clamped through the two clamping slot boxes 4, and then, through The fastener 71 is engaged with the positioning groove 72 to engage the light shield 8 above the syringe placement rack 1, and the syringe is covered with light by the light shield 8, and the wing plate slot 6 on the light shield 8 is engaged with the syringe wing plate, and the output shaft of the servo motor 51 drives the screw rod 54 to rotate, and the screw rod 54 and the transmission nut 53 are threadedly transmitted, and the transmission nut 53 drives the sliding seat 52 to slide along the slide groove 55, and the sliding seat 52 drives the slot box 4 to move through the clamping mechanism 3, and the slot box 4 drives the syringe to press the circular plate to move, and the syringe pressing circular plate pushes the syringe piston to move, which first extracts the intravenous chemotherapy drugs, and then injects the intravenous chemotherapy drugs.
