Description

Drug infusion drive

Technical Field

The utility model belongs to the relevant technical field of medical equipment or drug control devices, and specifically relates to a drug infusion drive device suitable for various occasions such as home, hospital, public emergency, disaster relief, etc.

Background Art

In clinical practice, doctors often need to perform surface anesthesia on patients during ENT surgery to relieve their pain and improve the success rate of the surgery. However, in clinical practice, there is a lack of suitable medical devices dedicated to surface anesthesia. Clinicians often use simple combinations such as syringes + spray tubes, or apply anesthetic ointments. They need to be temporarily combined before use, which is very inconvenient for doctors to operate, and the drug dosage is difficult to measure and control.

Afterwards, the industry explored the use of sprays to deliver drugs through the nasal cavity. However, there are often some specific application scenarios for nasal drug delivery. For example: patients need to use several sprays in sequence to complete the combination of several drugs. For this application scenario, the current common practice is: medical staff or the patients themselves hold the independent spray bottles of each medicine in turn, and spray the medicine through the nasal cavity in turn. Another example: the patient's nasal cavity needs to be cleaned first, and then the nasal cavity is sprayed with drugs. For this application scenario, the current common practice is: through the spray assembly, it is connected to different medicine bottles and clean water containers respectively to complete the cleaning and medication of the patient's nasal cavity. Moreover, these spray assemblies are reusable and need to be cleaned and disinfected after each use.

As can be seen from the above, the current operation methods and corresponding equipment for nasal drug delivery are very cumbersome for medical staff and patients, and are not convenient for standardized operation. The dosage of the drug is also difficult to control, which greatly limits the application scenarios. In particular, when using drugs for children, it is even more difficult to implement effectively due to the subjective non-cooperation of children, or in other words, there are greater risks in the implementation process.

As shown in FIG1 , the drug infusion drive device provided in this embodiment includes a drug delivery component 10 and a drive component 20. The drug delivery component 10 is docked with the drive component 20. The drug delivery component 20 includes a drug delivery mechanism for drug infusion due to deformation. The drive component 20 includes a pressing mechanism. The driving end of the pressing mechanism realizes drug infusion by driving the drug delivery mechanism to deform.

Among them, the drug delivery mechanism of the drug delivery component 10 can adopt the structure of a drug storage container and a liquid pump, and the driving end of the top pressure mechanism realizes drug infusion by driving the liquid pump; wherein, the action of the liquid pump can be identified as a deformation. It can be understood that the drug delivery mechanism of the drug delivery component 10 can also adopt other structures, such as a piston-type drug delivery structure; in this case, the driving end of the top pressure mechanism realizes drug infusion by driving the piston action. Alternatively, the drug delivery mechanism of the drug delivery component 10 is a deformable capsule; in this case, the driving end of the top pressure mechanism realizes drug infusion by squeezing the capsule.

Next, an implementation scheme of the drug delivery assembly 10 is introduced by taking the structure of a drug storage container and a liquid extraction pump as an example.

As shown in Figures 1 and 2, the drug delivery component 10 includes a housing 11, a nozzle 12, three medicine storage containers 13 (one of which is blocked) and three liquid pumps 14. Each medicine storage container 13 is correspondingly provided with a liquid pump 14, forming three groups of medicine storage containers and liquid pumps, and is arranged in the housing 11. The nozzle 12 is arranged on the housing 11, and the liquid outlet of each liquid pump 14 is connected to the nozzle 12. When the drug delivery component 10 rotates relative to the driving component 20, the positions of each group of medicine storage containers and liquid pumps are switched, so that the driving component 20 switches to drive a single liquid pump 14 to operate. When each liquid pump 14 is in operation, it is used to pump out the liquid medicine in the corresponding medicine storage container 13 and transport it to the nozzle 12, and form a high-pressure spray drug delivery at the nozzle 12.

Referring to FIG. 2 , FIG. 4 and FIG. 5 , the housing 11 includes a barrel 111 and a barrel cover 112 mounted on the upper end of the barrel 111 , and the nozzle 12 is provided on the barrel cover 112 , and atomization holes 121 corresponding to the number of the liquid pumps 14 are provided on the nozzle 12 (see FIG. 1 , in this embodiment, there are three atomization holes 121 ); the liquid outlet of each liquid pump 14 is connected to a corresponding atomization hole 121 through a drainage tube. Specifically, referring to FIG. 5 , the nozzle 12 protrudes from the upper surface of the barrel cover 112 and its shape is adapted to the nasal cavity, a nozzle column 122 is embedded in the nozzle 12, and nozzle holes corresponding to the atomization holes 121 are provided in the nozzle column 122 , and spray heads 123 are provided in the nozzle holes.

As shown in FIG2 , the liquid pump 14 is a push-type liquid pump, including a pump body 141 extending into the medicine storage container 13 and a push portion 142 disposed on the outside of the head of the medicine storage container 13; the liquid outlet of the liquid pump 14 is disposed on the side of the push portion 142, and the liquid outlet of each liquid pump 14 is connected to the nozzle 12 via a drainage tube 15. When the liquid pump 14 is a push-type liquid pump, there are two ways to realize the above-mentioned driving of the liquid pump 14: one is that the push portion 142 is fixed and the medicine storage container 13 is driven to move relative to the push portion 142 to drive the liquid pump 14 to move; the other is that the medicine storage container 13 is fixed and the push portion 142 is driven to move relative to the push portion 142 to drive the liquid pump 14 to move.

In addition, in other optional embodiments, the liquid pump 14 may also be an electric liquid pump. When the liquid pump 14 is an electric liquid pump, the above-mentioned driving liquid pump 14 is implemented as follows: the driving assembly 20 switches to drive the motor of a single electric liquid pump to drive the corresponding liquid pump 14 to operate.

As shown in Fig. 6, three sectors are divided around the longitudinal axis in the cylinder 111, and three groups of medicine storage containers and liquid pumps are arranged in the corresponding sector-shaped sectors. As shown in Fig. 5 and Fig. 6, the bottom of the cylinder 111 is contracted relative to the main body to form a docking portion 113, and the bottom of the docking portion 113 is provided with a limit frame 114 to limit each group of medicine storage containers and liquid pumps in the corresponding sector-shaped sectors; the limit frame 114 is provided with a driving operation port 115 corresponding to each group of the medicine storage containers and liquid pumps; the driving end of the driving assembly 20 can pass through the driving operation port 115 aligned with it after rotation and drive the corresponding liquid pump 14 to operate.

4, 5 and 6, the medicine storage container 13 is axially movably arranged in the corresponding fan-shaped partition, the pressing portion 142 of the push-type liquid pump 14 is abutted against the inner wall of the cylinder cover 112, and the driving end of the driving component 20 drives the liquid pump 14 to move by pushing the tail of the medicine storage container 13.

Specifically, in conjunction with Figures 7 and 8, the medicine storage container 13 includes a cartridge 131 and an end cap 132. The cartridge 131 has an opening at the head and is installed with the end cap 132, and the liquid pump 14 is installed on the end cap 132. The cross section of the main body of the cartridge 131 is fan-shaped, and the tail is a driven portion 135 that is smaller than the main body; the driven portion 135 is embedded in the corresponding driving operation port 115, and the main body of the cartridge 131 is supported on the limiting frame 114. In this embodiment, the fan-shaped cross section of the cartridge 131 of each of the three medicine storage containers 13 can be two 90-degree fans with one 180-degree fan.

5 and 6, each medicine storage container 13 also includes a dosing head 136 for adding medicine into the medicine barrel 131, which is arranged on each end cover 132. At the same time, a dosing port 119 is provided on the barrel cover 112 at a position corresponding to the dosing head 136, as shown in FIG1.

As mentioned above, when the liquid pump 14 is a push-type liquid pump, there are two ways to drive the liquid pump 14 to move. Correspondingly, there are also two ways to set each group of medicine storage containers and liquid pumps in the corresponding fan-shaped partitions. The above paragraph combined with Figures 4 to 6 gives one of the ways. The following is another implementation method, namely: the medicine storage container 13 is fixedly set in the corresponding fan-shaped partition, and the tail of the medicine storage container 13 is abutted against the inner wall of the barrel cover 112. The driving part of the driving component 20 drives the liquid pump 14 to move by pushing the pressing part 142. In this way, the pressing part 142 of each liquid pump 14 is located in the corresponding driving operation port 115, and the head end face of the cartridge 131 is supported on the limit frame 114.

3 , 4 and 5 , the drug infusion drive device provided in this embodiment further includes a protective cover 30 , which is detachably covered on the top of the housing 11 , and the protective cover 30 is used to cover the nozzle 12 therein to protect the nozzle 12 .

Referring to Figures 9 and 10, as an alternative embodiment, two sector-shaped partitions can be divided around the longitudinal axis in the barrel 111, and two groups of medicine storage containers and the liquid pump are arranged in the corresponding sector-shaped partitions. The sector-shaped cross-section of the cartridge 131 of the two medicine storage containers 13 can be a 90-degree sector with a 180-degree sector, a 90-degree sector with a 270-degree sector, or a 180-degree sector with a 180-degree sector.

As shown in combination with FIG. 7 and FIG. 11 , a docking slot 220 is provided on the docking seat 22, and the docking portion 113 is docked with the docking seat 22 in an embedded manner. Specifically, an embedding guide slot 222 is longitudinally provided on the slot wall of the docking slot 220, and a rotation guide slot 223 is circumferentially provided on the slot wall of the docking slot 220; a rotation guide block 118 is convexly provided on the outer edge of the docking portion 113, and when the docking portion 113 is embedded in the docking slot 220, the rotation guide block 118 is embedded in the rotation guide slot 223 through the embedding guide slot 222 and rotates in the rotation guide slot 223, thereby realizing that the drug delivery component 10 is rotatably docked with the drive component 20 relative to the drive component 20.

In conjunction with Figures 12 to 14, when the docking portion 113 rotates relative to the docking seat 22 (i.e., when the medication assembly 10 rotates relative to the driving assembly 20), the driving hole 221 on the docking seat 22 can be switchably aligned with the three driving operating ports 115 on the docking portion 113; thereby, the driving end 231 of the pressing mechanism 23 can pass through the driving hole 221 and the corresponding driving operating port 115 to drive the corresponding liquid pump 14 to operate.

The pressing mechanism 23 includes a motor, a screw and a screw sleeve, the motor drives the screw to rotate, drives the screw sleeve to move up and down, and the end of the screw sleeve serves as the driving end. Alternatively, the pressing mechanism 23 includes an electromagnet and a piston rod, the electromagnet drives the piston rod to move up and down through an attraction or repulsion force, and the end of the piston rod serves as the driving end.

4 and 15 , the driving assembly 20 further includes a sensing mechanism 27 for sensing whether the driving operation port 115 on the docking portion 113 is aligned with the driving hole 221 on the docking seat 22. Specifically, the sensing mechanism 27 includes a C-shaped mounting plate 271 and three Hall elements 272, and the three Hall elements 272 are respectively mounted on the head, tail and middle of the C-shaped mounting plate 271. A mounting groove 227 is provided at the bottom of the docking seat 22, and a mounting plate 271 together with a Hall element 272 are arranged in the mounting groove 227; in addition, a magnet 273 (i.e., a sensed element, see FIG4 ) is provided on the limit frame 114 at the bottom end of the docking portion 113; when the docking portion 113 rotates relative to the docking seat 22 and the sensing mechanism 27, the three Hall elements 272 on the sensing mechanism 27 determine the relative position of the docking portion 113 relative to the docking seat 22 by confirming whether the magnet 273 (see FIG4 ) provided on the limit frame 114 is sensed, and thus it is possible to determine which group of drug storage containers and the driving operation port 115 of the liquid pump in the current drug delivery component 10 are aligned with the driving end 231 of the pressing mechanism 23 and the driving hole 221 of the docking seat 22.

As mentioned above, the docking portion 113 can rotate relative to the docking seat 22, which is equivalent to the entire drug delivery component 10 being able to rotate relative to the driving component 20; the purpose of the rotation is to switch and rotate one of the three groups of drug storage containers 13 and the liquid pump 14 to the corresponding position of the driving hole 221 of the docking seat 22, so that the driving end 231 of the pressing mechanism 23 drives the corresponding liquid pump 14 to operate.

In order to provide a more obvious operational feel and feedback to the user when a group of switches rotates to the driving hole 221 of the docking seat 22 to reach the alignment position during the rotation process, a positioning mechanism is provided between the cylinder 111 of the medication assembly 10 and the docking seat 22 in this embodiment, and the positioning mechanism is used to form a jamming feeling that can be resisted and eliminated for the cylinder 111 located at the alignment position.

Specifically, the positioning mechanism includes a plunger and a positioning groove corresponding to the docking position of the docking seat 22 and the cylinder 111. Specifically, as shown in FIG5, a first group of positioning grooves 101 are provided at the periphery of the docking portion 113 at the bottom of the cylinder 111; as shown in FIG15, a first group of plungers 102 matching the first group of positioning grooves 101 are provided at the top of the outer wall of the docking groove 220 of the docking seat 22. In addition, as shown in FIG5, a second group of positioning grooves 103 are provided on the limiting frame 114 at the bottom of the cylinder 111; as shown in FIG15, a second group of plungers 104 matching the second group of positioning grooves 103 are provided on the bottom wall of the docking groove 220 of the docking seat 22.

As shown in FIGS. 5 to 7 , a positioning column 116 is protruding downward from the bottom center of the docking portion 113 .

When the docking portion 113 is inserted into the docking groove 220 , the positioning column 116 passes through the positioning hole 224 .

Based on this, in order to position a certain group of switches to rotate to the driving hole 221 of the docking seat 22 to reach the alignment position, the following alternative scheme can also be adopted: in combination with Figure 4, a rotary drive motor with a driving end facing upward is set in the center of the housing 21 (not shown in the figure), and when the docking part 113 is embedded in the docking groove 220, the positioning column 116 passes through the positioning hole 224 and docks coaxially with the driving end of the rotary drive motor; in this way, by precisely controlling the rotation angle of the rotary drive motor, one of the three groups of medicine storage containers 13 and the liquid pump 14 can be accurately and automatically switched to the alignment position of the driving hole 221 of the docking seat 22.

Alternatively, teeth are provided on the periphery of the docking portion 113, the rotary drive motor is eccentrically provided in the housing 21, and a gear is provided at the driving end of the rotary drive motor; when the docking portion 113 is inserted into the docking groove 220, the positioning column 116 passes through the positioning hole 224, and the teeth on the periphery of the docking portion 113 mesh with the gear at the driving end of the rotary drive motor. In this way, by precisely controlling the rotation angle of the rotary drive motor, one of the three groups of medicine storage containers 13 and the liquid pump 14 can also be precisely and automatically switched to the alignment position of the drive hole 221 of the docking seat 22.

In addition, referring to Figures 5 to 7, a locking flange 117 is provided at the bottom end of the positioning column 116; at the same time, in combination with Figures 4 and 15, a locking mechanism 40 is provided below the docking seat 22, and the locking mechanism is used to lock or release the locking flange 117 to lock the drive assembly 20 and the medication assembly 10 that are docked with each other.
