Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a portable gastrointestinal drug delivery pressurization device for nursing. Background Technology

[0002] A portable gastrointestinal drug delivery pressurization device is a portable medical device that integrates pressurization functionality, designed to deliver medications precisely and controllably to the lesion site in the patient's gastrointestinal tract. Its background technology stems primarily from the limitations of traditional drug delivery methods: for patients with severe gastrointestinal problems, conventional oral or subcutaneous injections often fail to achieve ideal therapeutic effects, necessitating direct delivery of medications to the intestines.

[0003] The existing technology has the following main shortcomings: On the one hand, traditional peristaltic pump-type drug delivery devices are mostly integrated fixed structures, and their pump tubing is usually encapsulated inside the pump body. If maintenance or replacement is required, it often requires disassembling a large number of fasteners, which is cumbersome and time-consuming, seriously affecting the maintenance efficiency in clinical nursing. On the other hand, existing devices generally lack the function of actively heating the infused drug solution. Directly administering low-temperature drug solution into the patient's stomach can easily cause abdominal discomfort or even spasms. Moreover, most devices rely solely on ordinary button switches for start-stop control, which cannot effectively prevent accidental activation during carrying or non-operational states, nor can it simultaneously cut off the flow channel when stopping drug delivery, posing a risk of drug backflow. All of these significantly reduce the safety of device use and patient comfort. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a portable gastrointestinal drug delivery pressurization device for nursing, which solves the problems of insufficient humanized design, inconvenient maintenance and inadequate design to prevent accidental operation of existing gastrointestinal drug delivery devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable gastrointestinal drug delivery pressurization device for nursing use, comprising a main shell, wherein the main shell is composed of a U-shaped plate and two partition plates, the U-shaped plate is provided with a limiting groove for limiting the pump tubing, the U-shaped plate is designed to be detachable, and includes two main plates and an arc plate, the main plates are fixedly connected to the partition plates, the arc plate is slidably connected to the main plates, and the two are locked together by bolts;

[0006] A heating module is located at the bottom of the arc-shaped plate. It contains an electric heating wire and has an independent power supply, which can heat the pump hose.

[0007] The rollers are rotatably connected to a rotating shaft seat inside the main body shell. Three rollers are rotatably connected to the rotating shaft seat and are arranged in a circular array. The width of the rollers is the same as the width of the limiting groove. A drive motor for driving the rotating shaft seat to rotate is also provided on one side of the main body shell. The output end of the drive motor is fixedly connected to the rotating shaft seat.

[0008] The guide partitions are symmetrically fixedly connected to the main body shell and located between the two partitions. The guide partitions are located on both sides of the main body shell towards the top. A synchronous locking mechanism is also provided at the top of the main body shell.

[0009] The synchronous locking mechanism includes a fixed partition plate disposed on the top of the main body shell. A transmission box is disposed at the center of the fixed partition plate. Bevel gears are rotatably connected to the top and both sides of the transmission box, with adjacent bevel gears meshing with each other. A knob is rotatably connected to the top of the transmission box, and this knob is connected to the bevel gear on the top of the transmission box. A lead screw is rotatably connected to both sides of the transmission box on the fixed partition plate, and this lead screw is connected to the bevel gear on the corresponding side. A push-button switch is disposed at the bottom of the transmission box, and it is electrically connected to the drive motor. The bottom of the bevel gear on the top of the transmission box is connected to the drive motor. A second lead screw is connected, and a second nut is threaded onto the second lead screw. Two pull rods are fixedly connected to the bottom of the second nut. The pull rods pass through the bottom of the transmission box and are slidably connected thereto. A pressure plate is fixedly connected to the bottom of the two pull rods. Two pairs of sliding grooves are provided on the fixed partition plate, and the two pairs of sliding grooves are distributed on both sides of the transmission box. A locking plate is slidably connected to each pair of sliding grooves. A first nut that matches the first lead screw is fixedly connected to the bottom of the locking plate. The locking plate is threadedly connected to the first lead screw on the corresponding side through the first nut at its bottom. The helical directions of the two first lead screws are opposite.

[0010] As a further embodiment of this utility model: the main body shell is also provided with a lithium battery for powering the drive motor, and the lithium battery is electrically connected to the drive motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model features a detachable U-shaped plate design for the main body shell, particularly the sliding connection between the arc-shaped plate and the main body plate, along with a bolt locking design. This makes the inspection, maintenance, and replacement of the pump tubing extremely quick. Compared to traditional one-piece structures, this design significantly simplifies the assembly and disassembly process, facilitating rapid operation in clinical nursing.

[0013] 2. By adding a heating module with independent power supply, this utility model can preheat the pumped medicine, effectively avoiding the irritation and discomfort caused by directly injecting low-temperature medicine into the stomach, thus improving the patient experience. On the other hand, by setting a synchronous locking mechanism, it can prevent accidental activation when carrying the medicine and interrupt the flow channel in time during delivery to prevent backflow of the medicine. At the same time, it realizes the linkage control of motor start-up and shutdown and pipeline on / off, significantly improving the safety and reliability of use. Attached Figure Description

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] Example 1

[0024] like Figures 1-4This is the first embodiment of the present invention. This embodiment provides a portable gastrointestinal drug delivery pressurization device for nursing use. Its overall structure is detachable. The arc plate 112 can be easily and quickly disassembled, allowing for rapid inspection and maintenance of the drug delivery hose. It includes: a main shell 1, which is composed of a U-shaped plate 11 and two partition plates 12. The U-shaped plate 11 has a limiting groove for limiting the drug delivery hose. The U-shaped plate 11 is detachable and includes two main plates 111 and an arc plate 112. The main plates 111 are fixedly connected to the partition plates 12, and the arc plate 112 is slidably connected to the main plates 111. The two are locked together by bolts.

[0025] It should be noted that this device is essentially a small, convenient peristaltic pump. It is designed based on the basic working principle of a peristaltic pump. In actual use, it works with a pump-drug tubing to deliver medication directly to the patient's stomach. The pump-drug tubing is arranged to fit against the inner wall of the U-shaped plate 11 and is engaged in the limiting groove. Since the U-shaped plate 11 is detachable, the pump-drug tubing can be quickly replaced by disassembling the arc plate 112.

[0026] Heating module 2 is located at the bottom of the arc plate 112. It contains an electric heating wire and is independently powered, which can heat the pump hose.

[0027] The medication, which is at ambient temperature, is delivered directly to the patient's stomach. Due to the significant temperature difference, it can directly irritate the patient's stomach and cause discomfort. The electric heating wire in heating module 2 can heat the pump tubing to improve the patient's experience.

[0028] Roller 3, rotating shaft seat 4 is rotatably connected inside the main body shell 1, three rollers 3 are rotatably connected inside the rotating shaft seat 4, the three rollers 3 are distributed in a circular array, the width of roller 3 is the same as the width of the limiting groove, and a drive motor 5 for driving the rotating shaft seat 4 is also provided on one side of the main body shell 1, the output end of the drive motor 5 is fixedly connected to the rotating shaft seat 4.

[0029] The drive motor 5 drives the rotating shaft seat 4 to rotate, and the three rollers 3 slowly make circular motions, continuously compressing the pump medicine hose, thereby continuously pumping the medicine from one end to the other. Its basic principle is basically the same as that of a peristaltic pump, so it will not be explained in detail.

[0030] Two guide partitions 6 are symmetrically fixedly connected inside the main body shell 1 and located between two partitions 12. The guide partitions 6 are located on both sides of the main body shell 1 towards the top. A synchronous locking mechanism 7 is also provided at the top of the main body shell 1. A lithium battery 8 for powering the drive motor 5 is also provided on the main body shell 1. The lithium battery 8 is electrically connected to the drive motor 5.

[0031] The guide baffle 6 is designed to limit and guide both ends of the pump tubing, making it easier to connect the tubing to the infusion tube or gastric tube. The lithium battery 8 is rechargeable and can power the drive motor 5.

[0032] Example 2

[0033] like Figures 5-7 The following is a description of the second embodiment of this utility model. Unlike the previous embodiment, this embodiment provides a portable gastrointestinal medication pressurization device for nursing use and its synchronous locking mechanism 7. The synchronous locking mechanism 7 includes a fixed partition 71 located on the top of the main body shell 1. A transmission box 72 is located at the center of the fixed partition 71. Bevel gears 73 are rotatably connected to the top and both sides of the transmission box 72, with adjacent bevel gears 73 meshing with each other. A knob 74 is rotatably connected to the top of the transmission box 72, and this knob 74 is connected to the bevel gear 73 on the top of the transmission box 72. A lead screw 75 is rotatably connected to both sides of the transmission box 72 on the fixed partition 71, and each lead screw 75 is connected to the bevel gear 73 on the corresponding side. The bottom of the transmission box 72... A push-button switch 76 is provided, which is electrically connected to the drive motor 5. The bottom of the bevel gear 73 at the top of the transmission box 72 is connected to the second lead screw 77. The second lead screw 77 is threaded with a second lead screw 78. The bottom of the second lead screw 78 is fixedly connected to two pull rods 79. The pull rods 79 pass through the bottom of the transmission box 72 and are slidably connected to it. The bottom of the two pull rods 79 is fixedly connected to a pressure plate 710. The fixed partition 71 has two pairs of sliding grooves, which are distributed on both sides of the transmission box 72. Each pair of sliding grooves is slidably connected to a locking plate 711. The bottom of the locking plate 711 is fixedly connected to a first lead screw 75 that matches the first lead screw 75. The locking plate 711 is threadedly connected to the first lead screw 75 on the corresponding side through the first lead screw 75 at its bottom. The spiral directions of the two first lead screws 75 are opposite.

[0034] The purpose of the synchronous locking mechanism 7 is to synchronously control the start and stop of the drive motor 5 and the opening and closing of both ends of the pump tubing via the knob 74, so as to avoid accidental start-up caused by patients accidentally touching it during daily carrying. In addition, the timely disconnection of the pump tubing during drug delivery can also prevent drug backflow, which is something that ordinary push-button switches cannot do.

[0035] Its basic working principle is that the corresponding bevel gear 73 in the transmission box 72 is controlled by manually turning the knob 74. The transmission box 72 is essentially a bevel gear reversing device. The bevel gear branches and reverses the power, thereby synchronously driving the two lead screws 75 on both sides to rotate. Since the locking plate 711 is threadedly connected to it through the lead screw nut, the two locking plates 711 can move synchronously and in opposite directions. Thus, when the knob 74 is turned, the two locking plates 711 can be synchronously controlled to lock and jam the two ends of the pump medicine hose, thereby interrupting the flow channel.

[0036] Secondly, the second lead screw 77 and the second lead screw nut 78 form a lead screw pair. The two work together to lift or lower the pressure plate 710. Of course, through the connection of the pull rod 79, when the pressure plate 710 moves upward, the push button switch 76 can be triggered, thereby starting the drive motor 5.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
