Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an administration device for bedridden patients in the respiratory medicine department. Background Technology

[0002] Respiratory medicine is a branch of internal medicine that specializes in the diagnosis and treatment of respiratory diseases. It focuses on various diseases related to the respiratory system. The main characteristics of respiratory diseases are varying degrees of damage to the respiratory system and varying degrees of decline in respiratory function. In the clinical nursing of respiratory medicine, administering medication to bedridden patients is an important and complex task.

[0003] For example, Chinese patent CN201920819587.7 discloses a clinical drug delivery device for respiratory patients. The device disperses and delivers the drug solution to the patient's respiratory tract through a drug delivery structure. The drug solution is sprayed into the patient's respiratory tract, fully covering the patient's respiratory tract. The patient's respiratory tract is completely covered by the drug, resulting in good therapeutic effect and fast recovery.

[0004] However, the inability to perform intermittent automated administration during respiratory drug delivery necessitates frequent manual intervention by healthcare professionals, which increases their workload and adds uncertainty to the drug delivery process.

[0005] Based on this, the present invention designs an administration device for bedridden patients in the respiratory medicine department to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an administration device for bedridden patients in the respiratory medicine department to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drug delivery device for bedridden patients in the respiratory medicine department, comprising an installation box, an intermittent mechanism, and a drug delivery component. The intermittent mechanism is provided in the inner cavity of the installation box, and the drug delivery component is connected to the top of the installation box. The drug delivery component is drivenly connected to the intermittent mechanism. The intermittent mechanism includes a fixed sleeve, a fixed rod, a limiting block, a toothed groove, and an inner toothed ring. The fixed rod is fixedly connected to the outer edge of the fixed sleeve, and the limiting block is connected to the end of the fixed rod away from the fixed sleeve. The limiting block has a toothed groove on its edge. The inner toothed ring is fixedly connected to the inner wall of the rear side of the installation box. The inner toothed ring is coaxially arranged with the fixed sleeve, and the limiting block is engaged with the inner toothed ring through the toothed groove.

[0008] Preferably, a servo motor is fixedly installed on the rear side of the mounting box, and the output end of the servo motor passes through the mounting box and is fixedly connected to the fixing sleeve.

[0009] Preferably, the intermittent mechanism further includes a short transmission rod and a long transmission rod, the short transmission rod being fixedly connected to the front side of the fixed rod, and the long transmission rod being rotatably connected to the end of the short transmission rod away from the fixed sleeve.

[0010] Preferably, the drug delivery assembly includes a drug delivery cylinder, a piston block, and a connecting rod. The piston block is slidably connected to the inner wall of the drug delivery cylinder, and the connecting rod is fixedly connected to the center of the bottom of the piston block. The bottom end of the connecting rod passes through the bottom of the mounting box and is rotatably connected to the other end of a transmission rod.

[0011] Preferably, the top of the drug delivery cylinder has a drug outlet and a drug inlet on the left and right sides respectively. Both the drug outlet and the drug inlet are connected to a delivery pipe through a union joint. The delivery pipe communicates with the inside of the drug delivery cylinder and is connected to a one-way valve.

[0012] Preferably, a limiting seat is fixedly connected at the center of the top of the inner cavity of the mounting box, and a connecting rod is slidably connected inside the limiting seat.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] I. This utility model, through the cooperation of an intermittent mechanism and a drug delivery component, uses a servo motor to drive the rotation of the transmission rod, which is then converted into the up-and-down movement of the piston block within the drug delivery cylinder via a connecting rod. This allows the drug delivery device to automatically draw in, compress, and discharge the drug solution at a certain frequency and cycle, achieving intermittent automatic drug delivery. This improves drug delivery efficiency and patient comfort. At the same time, the one-way valve on the delivery pipe ensures unidirectional flow of the drug solution, preventing backflow and improving the safety of drug delivery.

[0015] Second, by setting an internal toothed ring, this utility model can provide a limit during the rotation of the transmission rod, so that the transmission rod can rotate along a preset trajectory, ensuring the stable operation of the intermittent mechanism. By setting a limit seat, the linearity of the connecting rod during the movement is ensured, so that the connecting rod can accurately return to the initial position in each rotation cycle, preparing for the next drug delivery action.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1 - Figure 4 Example 1 illustrates a drug delivery device for bedridden patients in the respiratory medicine department, comprising a mounting box 1, an intermittent mechanism 2, and a drug delivery component 3. The intermittent mechanism 2 is disposed in the inner cavity of the mounting box 1, and the drug delivery component 3 is connected to the top of the mounting box 1. The drug delivery component 3 is connected to the intermittent mechanism 2 via a transmission connection. The intermittent mechanism 2 includes a fixed sleeve 201, a fixed rod 202, a limiting block 203, a toothed groove 204, and an inner toothed ring 205. The fixed rod 202 is fixedly connected to the outer edge of the fixed sleeve 201, and the end of the fixed rod 202 away from the fixed sleeve 201 is connected to the limiting block 203. The edge of the limiting block 203 has a toothed groove 204. The inner toothed ring 205 is fixedly connected to the inner wall of the rear side of the mounting box 1. The inner toothed ring 205 is coaxially disposed with the fixed sleeve 201, and the limiting block 203 is engaged with the inner toothed ring 205 through the toothed groove 204.

[0026] Please see Figure 1 and 3 The servo motor 4 is fixedly installed on the rear side of the mounting box 1 shown in the figure. The output end of the servo motor 4 passes through the mounting box 1 and is fixedly connected to the fixing sleeve 201.

[0027] Furthermore, the intermittent mechanism 2 also includes a short transmission rod 206 and a long transmission rod 207. The short transmission rod 206 is fixedly connected to the front side of the fixed rod 202, and the long transmission rod 207 is rotatably connected to the end of the short transmission rod 206 away from the fixed sleeve 201.

[0028] In this embodiment, the servo motor 4 outputs power when powered on, driving the fixed sleeve 201 to rotate. Due to the meshing relationship between the tooth groove 204 of the limiting block 203 and the inner tooth ring 205, the rotation of the fixed sleeve 201 will drive the limiting block 203 to move along the tooth profile of the inner tooth ring 205. At the same time, the transmission short rod 206 moves together with the fixed rod 202, while the transmission long rod 207 rotates due to its rotational connection with the transmission short rod 206. The drug delivery component 3 performs intermittent drug delivery operation through this rotational movement.

[0029] It should be noted that the servo motor 4 can be a DC motor with high torque, high precision and low noise. The speed is adjusted by an electronic speed controller. When the servo motor 4 is running continuously, the drug delivery component 3 will automatically perform drug inhalation, compression and discharge according to a certain frequency and cycle, thereby improving drug delivery efficiency and patient comfort. This allows medical staff to perform nursing work more easily and reduces their workload. Furthermore, shock-absorbing pads or shock absorbers can be installed on the outside of the servo motor 4 to reduce the impact of the vibration generated during its operation on the overall drug delivery device.

[0030] Example 2

[0031] Please see Figure 5 and Figure 6 Example 2 is described below. This embodiment further illustrates Example 1. The drug delivery assembly 3 shown in the figure includes a drug delivery cylinder 301, a piston block 302, and a connecting rod 303. The piston block 302 is slidably connected to the inner wall of the drug delivery cylinder 301. The connecting rod 303 is fixedly connected to the center of the bottom of the piston block 302. The bottom end of the connecting rod 303 passes through the bottom of the mounting box 1 and is rotatably connected to the other end of the transmission rod 207.

[0032] Furthermore, the top of the drug delivery cylinder 301 is provided with a drug outlet 5 and a drug inlet 6 on the left and right sides respectively. Both the drug outlet 5 and the drug inlet 6 are connected to a delivery pipe 7 through a union joint. The delivery pipe 7 is connected to the inside of the drug delivery cylinder 301 and a one-way valve 8 is connected to the delivery pipe 7.

[0033] In this embodiment, when the transmission rod 207 rotates, the connecting rod 303 drives the piston block 302 to move up and down inside the drug delivery cylinder 301, thereby realizing the inhalation and exhalation of the drug liquid. During the drug delivery process, the one-way valve 8 on the delivery pipe 7 in the drug inlet 6 opens, and the drug liquid is drawn into the drug delivery cylinder 301 through the drug inlet 6 and the one-way valve 8 closes. As the transmission rod 207 continues to rotate, it drives the piston block 302 to move downward, and the one-way valve 8 on the delivery pipe 7 in the drug outlet 5 opens. The drug liquid is compressed and discharged through the drug outlet 5, and delivered to the patient's respiratory tract via the delivery pipe 7. The one-way valve 8 on the delivery pipe 7 ensures the one-way flow of the drug liquid and prevents backflow.

[0034] Specifically, the servo motor 4 drives the short transmission rod 206 in the intermittent mechanism 2 to rotate in the internal gear ring 205, which in turn drives the long transmission rod 207 to rotate periodically. In each rotation cycle, the up and down movement of the long transmission rod 207 precisely controls the position of the piston block 302 in the drug delivery cylinder 301, thereby ensuring the accurate intake and discharge of the drug liquid.

[0035] Example 3

[0036] Please see Figure 1 and Figure 3 Example 3 is described below. This embodiment further describes Example 2. In the figure, a limiting seat 9 is fixedly connected at the center of the top of the inner cavity of the mounting box 1. A connecting rod 303 is slidably connected inside the limiting seat 9.

[0037] In this embodiment, during the drug administration process, driven by the servo motor 4, the rotational motion of the transmission rod 207 is converted into the up-and-down movement of the piston block 302 within the drug administration cylinder 301 via the connecting rod 303. The limiting seat 9 ensures the linearity of the connecting rod 303 during the movement, so that the connecting rod 303 can accurately return to the initial position in each rotation cycle, preparing for the next drug administration action.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
