Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drug quantitative extraction device. Background Art

[0002] Radiopharmaceuticals refer to radionuclide preparations or their labeled compounds used for clinical diagnosis or treatment. The difference between radiopharmaceuticals and other drugs is that the radionuclides contained in radiopharmaceuticals can emit rays. Therefore, all drugs that contain radionuclides in their molecules or preparations are called radiopharmaceuticals.

[0003] In the medical field, when radioactive drugs need to be injected into patients, the activity of these drugs will gradually decrease over time due to the natural decay of radioactive elements. This means that in order to maintain a consistent activity for each injection, the volume of drug required to be extracted will increase over time. For example, at 8:00 a.m., it may only take 0.7 ml to extract 20mCi of drug, but at 10:00 a.m., in order to obtain the same 20mCi activity, it may be necessary to extract 0.8 ml or more. Currently, medical staff usually use syringes to manually extract such drugs, relying on the naked eye and experience to estimate the required volume, and then measure the activity achieved. However, it is difficult to successfully extract the required injection activity in one go, and repeated extraction and measurement will occur. This method not only makes it difficult to achieve accurate quantitative extraction, resulting in drug waste or inaccurate dosage, but also exposes the operator to repeated radiation exposure, while also reducing work efficiency.

DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example: A drug quantitative extraction device, such as Figure 1-Figure 5As shown, it includes a protective shell 1, a sealing door panel 2, a pillar 21, a storage component, a sleeve 3, a fixing seat 31, a one-way screw 32, a motor a33, a crossbeam, a clamping component and a pushing component. The protective shell 1 is a rectangular hollow shell with an opening on the upper side of the front. The protective shell 1 is slidably connected to the sealing door panel 2 at the opening. The top of the bottom panel of the protective shell 1 is symmetrically fixed with pillars 21. A storage component for storing medicines is provided in the middle of the top of the bottom panel of the protective shell 1. Sleeves 3 are slidably connected to the two pillars 21. The pillar 21 on the right side is symmetrically fixedly connected to the fixing seat 31 above and below, and a one-way screw rod 32 is rotatably connected between the two fixing seats 31. A motor a33 is installed at the lower part of the pillar 21 on the right side, and the output shaft end of the motor a33 is fixedly connected to the lower end of the one-way screw rod 32. A crossbeam 4 is fixedly connected between the rear sides of the two sleeves 3. A clamping assembly and a pushing assembly are provided on the crossbeam 4. A syringe is placed on the pushing assembly. The clamping assembly is used to clamp and fix the syringe, and the pushing assembly is used to push the syringe to extract the medicine.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the storage assembly includes a liquid storage tank 22, a cover 23, a U-shaped slide rail 24, a sealing plate 25 and an electric push rod a26. The liquid storage tank 22 is fixedly connected to the middle of the bottom panel of the protective shell, and the front part of the liquid storage tank 22 passes through the front panel of the protective shell 1 and is located outside it. A liquid filling port is provided on the front side of the top of the liquid storage tank 22, and a cover 23 is threadedly connected to the liquid filling port. A U-shaped slide rail 24 is fixedly connected to the middle of the top of the liquid storage tank 22, and a sealing plate 25 is slidably provided on the U-shaped slide rail 24. An electric push rod a is installed on the rear side of the top of the liquid storage tank 22, and the telescopic rod end of the electric push rod a is fixedly connected to the sealing plate 25. A circular opening is opened on the rear side of the top of the liquid storage tank 22, and the sealing plate 2 can close the circular opening.

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, the clamping assembly includes an arc-shaped splint 52, a bidirectional screw rod 53 and a motor b54. A slide groove 51 is opened in the middle of the beam 4, and the arc-shaped splint 52 is symmetrically slidably arranged at the slide groove 51. The middle of the beam 4 is rotatably connected with a bidirectional screw rod 53. The bidirectional screw rod 53 passes through the two arc-shaped splints 52 respectively and cooperates with them through threads. A motor b54 is installed on the right side of the beam 4, and the output shaft end of the motor b54 is fixedly connected to the right end of the bidirectional screw rod 53.

[0023] like Figure 3 and Figure 4As shown, the pushing assembly includes a fixed plate 61, a limiting plate 62, a sliding plate 63, a U-shaped push plate 64, an electric push rod b65 and a control panel 66. The top of the crossbeam 4 is fixedly connected to two fixed plates 61 at intervals. The upper parts of the two fixed plates 61 are fixedly connected to the limiting plates 62. A syringe is placed between the tops of the two limiting plates 62. The two fixed plates 61 are slidably provided with sliding plates 63. The tops of the two sliding plates 63 are fixedly connected to the U-shaped push plate 64. The electric push rod b65 is installed in the middle of the top of the crossbeam 4. The top of the lifting and retracting rod of the electric push rod b65 is connected to the bottom of the U-shaped push plate 64. The syringe is fixedly connected, and the syringe consists of a syringe 001, a bump 002, a piston column 003 and a piston handle 004. The bumps 002 are symmetrically arranged on the upper side of the outer wall of the syringe 001. The syringe is placed on the limit plate 62 through the two bumps 002. A piston rod is slidingly arranged inside the syringe 001, and a piston handle 004 is arranged on the top of the piston rod. The top of the U-shaped push plate 64 is fitted with the bottom of the piston handle 004. A control panel 66 is installed on the right side of the protective shell 1, and the control panel 66 is electrically connected to the motor a33, the motor b54, the electric push rod a26 and the electric push rod b65 respectively.

[0024] First, the medical staff slides the sealing door panel 2 to the left to open it, and then securely places the syringe on the limit plate 62 through the two protrusions 002 on it, and ensures that the bottom of the syringe piston handle 004 is tightly fitted with the top of the U-shaped push plate 64. Then, the motor b54 is started, and the motor b54 drives the bidirectional screw rod 53 to rotate, thereby driving the two arc-shaped clamping plates 52 to move closer to each other, thereby achieving a firm clamping of the syringe barrel 001. The medical staff then slides the sealing door panel 2 to the right to reset it, so that the syringe is in the sealed space inside the protective shell 1, and then controls the control panel 66. The electric push rod a26 is started, and the telescopic rod of the electric push rod a26 retracts, thereby driving the sealing plate 25 to slide backward, thereby opening the circular opening in the middle of the top of the liquid storage tank 22. At this time, the medical staff starts the motor b54 through the control panel 66. The motor b54 drives the one-way screw 32 to rotate, thereby driving the sleeve 3 on the right to slide downward to the appropriate position, so that the needle set at the bottom of the syringe can penetrate into the liquid storage tank 22 to the appropriate depth through the circular opening. After everything is ready, the medical staff enters the volume of medicine to be extracted on the control panel 66. The control panel 66 then starts the electric push rod b65 and controls the telescopic rod of the electric push rod b65 to extend upward to the specified length, thereby pushing the U-shaped push plate 64 upward to a corresponding height. During this process, the U-shaped push plate 64 will push the piston handle 004 of the syringe, thereby moving the piston rod 003 upward in the syringe 001 to extract the specified volume of medicine. In this way, accurate quantitative extraction of the medicine is achieved, effectively avoiding the waste of medicine. When the syringe completes the extraction of the medicine, the medical staff controls the motor a33 to reverse again through the control panel 66, and the motor a3 3 reverses and drives the one-way screw rod 32 to rotate in the opposite direction, so that the sleeve 3 slides upward and resets, and then the syringe is reset upward, and then the control panel 66 controls the motor b to reverse, and the motor b54 reverses and drives the two-way screw rod 53 to rotate in the opposite direction, so that the two arc-shaped clamping plates 52 move away from each other, releasing the clamping of the syringe, and at the same time, the control panel 66 controls the electric push rod a26 to drive the sealing plate 25 to re-seal the circular opening in the middle of the top of the liquid storage tank 22. After the medical staff slides the sealing door panel 2 to the left and pulls it open, the syringe can be removed from the device for subsequent operations.

[0025] like Figure 3 As shown, rubber pads 71 ​​are also included. Rubber pads 71 ​​are provided on the facing side walls of the two clamping plates.

[0026] By arranging the rubber pad 71 at the contact portion between the arc-shaped clamping plate 52 and the syringe, the friction between the arc-shaped clamping plate 52 and the syringe can be effectively increased. This not only prevents the syringe from sliding upward during the extraction of the medicine, ensuring the stability of the extraction, but also avoids damage to the syringe due to excessive clamping, that is, prevents the syringe from being damaged by the clamping plate.

[0027] like Figure 5 As shown, a support plate 7 is also included. The lower rear sides of the two pillars 21 are fixedly connected to the support plate 7, and the lower ends of the two support plates 7 are fixedly connected to the bottom panel of the protective shell 1.

[0028] By providing the support plate 7, the maximum distance that the sleeve 3 slides downward on the pillar 21 can be limited. When the bottom of the sleeve 3 contacts the support plate 7, it can ensure that the needle set at the bottom of the syringe can still maintain a certain safety distance therebetween, thereby avoiding the needle from colliding with the bottom panel of the liquid storage tank 22 and being damaged. At the same time, the support plate 7 itself also provides additional support for the pillar 21, further improving the stability of the pillar 21.

[0029] like Figure 1 As shown, the lower part of the protective shell 1 is fixedly connected with an assembly block 8 in a left-right symmetrical manner.

[0030] By setting the assembly block 8, the assembly block 8 can cooperate with the bolts on the work surface. Through the tightening action of the bolts, the protective shell 1 can be firmly fixed on the work surface, which can increase the stability of the entire device and ensure its smooth operation during work.

[0031] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be within the scope of the claims herein.
