Description

Technical Field

[0001] The present invention relates to the technical field of drug delivery devices, in particular to an intestinal drug delivery device. Background Art

[0002] Gastroenterology is a tertiary clinical discipline that mainly studies diseases of the esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas. Gastroenterology covers a wide variety of diseases, a broad range of medical knowledge, and complex and delicate operations. In gastroenterology, when treating the intestines, it is necessary to administer medication to the intestines, so a drug delivery device is needed.

[0003] Currently, although intestinal drug delivery devices on the market can facilitate medical personnel to inject drugs into the patient's intestines in a quantitative manner through the drug delivery device, they are unable to clean the drug delivery hose immediately. When the drug delivery hose is removed from the patient's intestine, a lot of dirt will adhere to the surface of the drug delivery hose. If it is not cleaned immediately, the stains will drip from the surface of the drug delivery hose, thereby contaminating the surgical area. In the related art, a cleaning component is provided to flush the surface of the drug delivery hose, thereby achieving surface dirt cleaning immediately after the drug delivery hose is removed from the patient's intestine, preventing the stains on the surface of the drug delivery hose from dripping and causing contamination of the surgical area, that is, protecting the environment of the operating room and eliminating the need for staff to clean. However, in actual use, although the surface of the drug delivery hose can be cleaned only by rotating the cleaning brush, dirt will remain on the cleaning brush during actual use. When the brush rotates subsequently, the contact area between the dirt and the drug delivery hose is increased, reducing the cleaning effect. Although the cleaning effect is improved by subsequent water washing, the sewage will still contaminate the surgical area after being sprayed out during actual use, reducing practicality and inconvenience.

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0041] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0043] Currently, although the intestinal drug delivery devices on the market can facilitate medical staff to inject drugs into the patient's intestines in a quantitative manner through the drug delivery device, the drug delivery hose cannot be cleaned in the first time. When the drug delivery hose is taken out of the patient's intestines, a lot of dirt will adhere to the surface of the drug delivery hose. If it is not cleaned immediately, the stains will drip from the surface of the drug delivery hose, thereby contaminating the surgical area.

[0044] In the related technology, a cleaning component is set up to flush the surface of the drug delivery tube, so that the surface dirt can be cleaned as soon as the drug delivery tube is taken out of the patient's intestine, avoiding the dripping of stains on the surface of the drug delivery tube and causing pollution of the surgical area, that is, protecting the environment of the operating room and eliminating the need for staff to clean. However, in actual use, although the surface of the drug delivery tube can be cleaned only by rotating the cleaning brush, dirt will remain on the cleaning brush during actual use. When the brush rotates subsequently, the contact area between the dirt and the drug delivery tube will increase, reducing the cleaning effect. Although the cleaning effect is improved by subsequently cooperating with water washing, in actual use, the sewage will still contaminate the surgical area after being sprayed out, reducing practicality and inconvenient to use.

[0045] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides an intestinal drug delivery device. When it is needed, it is only necessary to rotate the ring body 22 after the drug addition is completed and the drug delivery tube 12 is taken out, so that the scraper 23 and the sponge 24 can be used together to clean the dirt remaining on the drug delivery tube 12, which is more convenient and quick, and improves the convenience of the device.

[0046] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0047] Combine Figure 1-Figure 5 The embodiment of the present application provides an intestinal drug delivery device, including a drug delivery device 10, a tonic drug tube 11 is provided on the outside of the drug delivery device 10, a drug delivery tube 12 is provided at one end of the drug delivery device 10, a mounting mechanism 20 is provided on the outside of the drug delivery tube 12, the mounting mechanism 20 is fixedly connected to a ring body 1 21, the inner side of the ring body 1 21 is rotatably connected to a ring body 22, the inner side of the ring body 22 is fixedly connected to a scraper 23, one end of the scraper 23 is provided with a sponge 24, the scraper 23 and the sponge 24 are both tightly attached to the drug delivery tube 12, the ring body 2 2 2 is fixedly connected to the outside of the gear 1 30, and the mounting mechanism 20 is rotatably connected to the gear 2 31, and the gear 1 30 is engaged with the gear 2 31. The mounting mechanism 20 is provided with a transmission mechanism 33, and the mounting mechanism 20 is provided with a transmission box 34. The transmission box 34 is rotatably connected to the gear 3 35, and the gear 2 31 is transmission-connected to the gear 3 35 through the transmission mechanism 33 and the transmission box 34. The outside of the drug dispenser 10 is fixedly connected to a rack 36, and the gear 3 35 is meshed with the rack 36.

[0048] During use, after the medicine is replenished into the inside of the drug delivery device 10 through the drug replenishing tube 11, the medical staff inserts the drug delivery tube 12 into the patient's anus by holding the drug delivery device 10, and pushes the drug delivery device 10 into the inside of the anus. After it contacts the rectum, the piston in the drug delivery device 10 is pushed to make the medicine pass through the drug delivery tube 12 and enter the patient's intestine, thereby achieving intestinal drug delivery. After the drug delivery is completed, the drug delivery device 10 is pulled outward while manually shifting the ring body 22 so that the ring body 22 rotates in the ring body 1 21, driving the scraper 23 to rotate. After the scraper 23 scrapes off the dirt on the outside of the drug delivery tube 12, the sponge 24 wipes off the dirt in the less liquid or solid-liquid mixed state remaining on the drug delivery tube, achieving a double cleaning effect. The cleaned impurities directly fall into the ring body 1 21 on the mounting mechanism 20. After the drug delivery is completed, the mounting mechanism 20 is disassembled and the dirt is cleaned.

[0049] When in use, push the ring body 22 clockwise (direction reference Figure 3 ), so that most of the dirt accumulates on the scraper 23, and when the ring body 22 is pushed counterclockwise, the scraper 23 directly pushes the dirt into the ring body 1 21, and can be used alternately clockwise and counterclockwise to improve the cleaning effect;

[0050] When administering the medicine, the positions of the ring body 1 21 and the ring body 2 22 are adjusted by operating the mounting mechanism 20 so that one side of the mounting mechanism 20 is always in contact with the patient, and the insertion depth of the dosing tube 12 is adjusted to limit the depth of administration and improve accuracy. After the administration is completed, the staff holds the mounting mechanism 20 with one hand and pulls the drug dispenser 10 outward with the other hand. The drug dispenser 10 drives the rack 36 to move, and then the gear 35 engages with the rack 36 to drive the gear 3 35 to rotate. Then, the gear 2 31 is rotated through the transmission mechanism 33 and the transmission box 34. Then, the gear 2 31 is engaged with the gear 1 30 to drive the ring body 2 22 to rotate. When the drug dispenser 10 is pulled outward, the scraper 23 and the sponge 24 work automatically, thereby realizing separate operation and improving practicality.

[0051] Specifically, a plurality of protrusions are provided on the outer side of the ring body 22 to facilitate medical personnel to manually push the ring body 22, such as Figure 1 shown.

[0052] In some embodiments, the mounting mechanism 20 includes: a slide rail 201 fixedly connected to the outside of the drug dispensing device 10; a ring body three 202 slidingly connected to the slide rail 201; a tightening bolt one 203 threadedly connected to the ring body three 202, and one end of the tightening bolt one 203 is tightened against the slide rail 201; a connecting plate 204 fixedly connected to one side of the ring body three 202; a mounting seat 205 fixedly connected to one end of the connecting plate 204, and the drug dispensing tube 12 passes through the mounting seat 205, the ring body one 21 is rotatably connected to the mounting seat 205, and the transmission box 34 is installed on the outside of the ring body three 202.

[0053] When in use, turn the fastening bolt 203 to disengage one end of it from the slide rail 201, then manually push the ring body 3 202 to slide on the slide rail 201, thereby adjusting the position of the mounting seat 205 through the connecting plate 204, and continuously pull the ring body 3 202 to disengage it from the slide rail 201 for disassembly, and vice versa for installation.

[0054] In some embodiments, a housing 40 is fixedly connected to the inner side of the mounting base 205 , and the gear 2 31 is rotatably connected to the inner side of the housing 40 .

[0055] The housing 40 covers and protects the gear 2 31 .

[0056] In some embodiments, the transmission mechanism 33 includes: a rod body 331 rotatably connected to the mounting base 205, and after one end of the rod body 331 is inserted into the shell 40, it is fixedly connected to the gear 2 31; a rod body 2 332 is arranged on one side of the transmission box 34; two pulleys 333 are provided, which are respectively fixedly connected to one end of the rod body 331 and rotatably connected to one side of the mounting base 205; a belt 334 and the two pulleys 333 are connected for transmission through the belt 334.

[0057] When gear 2 31 rotates, it drives a pulley 333 to rotate through rod 1 331, and then the two pulleys 333 rotate at the same time through the transmission of belt 334, so that the other pulley 333 drives rod 2 332 to rotate, and rod 2 332 drives gear 3 35 to rotate through transmission box 34.

[0058] In some embodiments, the transmission box 34 includes: a box body 341 fixedly connected to the outside of the ring body three 202; two bevel gears 342 are provided, which are respectively rotatably connected to the inner bottom surface of the box body 341 and rotatably connected to the outside of the rod body two 332, and the two bevel gears 342 are engaged with each other; the mounting rod 343 is rotatably connected to the box body 341 and fixedly connected to one of the bevel gears 342, the gear three 35 is fixedly connected to the outside of the mounting rod 343, and the gear three 35 is rotatably connected to the box body 341 through the mounting rod 343.

[0059] When the rod body 2 332 rotates, it drives the mounting rod 343 and the gear 3 35 to rotate through the bevel gear 342, thereby realizing transmission.

[0060] In some embodiments, the scraper 23 and the sponge 24 are a group, and multiple groups are arranged in the ring body 22, so that multiple scrapers 23 and multiple sponges 24 work simultaneously to achieve multiple cleaning.

[0061] In some embodiments, a mounting block 50 is provided on one side of the mounting seat 205, and a motor 51 is provided in the mounting block 50. The output end of the motor 51 and the side of one of the pulleys 333 are fixedly connected with a gear four 52, and the two gears four 52 are meshed with each other.

[0062] When in use, by turning on the motor 51, its output end drives a gear four 52 to rotate, and through the transmission connection of the two gear four 52, the other gear four 52 drives the pulley 333 to rotate, so that the pulley 333 drives the rod body 1 331 and the gear two 31 to rotate, realizing the operation of the scraper 23 and the sponge 24 by driving the motor 51, thereby improving practicality.

[0063] In some embodiments, a groove 60 is opened on one side of the mounting seat 205, and the mounting block 50 is slidably connected to the groove 60. A threaded rod 61 is rotatably connected to the mounting seat 205. After one end of the threaded rod 61 is inserted into the mounting block 50, it is threadedly connected to the mounting block 50. The rod body 2 332 is a telescopic rod, and the outer side is threadedly connected to a fixing bolt 2 70.

[0064] When in use, by rotating the fastening bolt outside the fastening bolt 70, the angle between the inner rod and the outer rod of the second rod body 332 is fixed, so that when the pulley 333 rotates, the bevel gear 342 can be driven to rotate through the second rod body 332. Conversely, after loosening the fastening bolt 70, the angle between the inner rod and the outer rod of the second rod body 332 is not fixed, so that when the pulley 333 rotates, the inner rod of the second rod body 332 rotates inside the outer rod, so that after the motor 51 is turned on, the gear 35 does not work, thereby improving practicality.

[0065] In actual use, the threaded rod 61 is rotated to adjust the position of the mounting block 50, so that the mounting block 50 drives the motor 51 to move, thereby switching the two gears 52 between the meshing or disengagement states, thereby improving practicality.

[0066] When the two gears 4 52 are not engaged, the ring body 22 is manually pushed to drive the scraper 23 and the sponge 24 to work. Alternatively, the applicator 10 can be pulled outward to cause the rack 36 to drive the gear 35 to rotate, ultimately causing the ring body 22 to drive the scraper 23 and the sponge 24 to work.

[0067] When the two gears 4 52 are not engaged and the fastening bolt 2 70 is loosened, the inner rod of the second rod body 332 can be fixed to the outer rod or not fixed to the outer rod by rotating the fastening bolt 2 70, so that the bevel gear 342 rotates or does not rotate when the pulley 333 rotates, thereby improving practicality;

[0068] When the two gears 4 52 are engaged and the fastening bolt 2 70 is loosened and the scraper 23 and the sponge 24 are put into operation by turning on the motor 51, the gear 3 35 does not work. When the fastening bolt 2 70 is tightened again and the angle between the inner rod and the outer rod in the rod body 2 332 is fixed, the motor 51 is turned on to make the scraper 23 and the sponge 24 work while the gear 3 35 rotates, thereby realizing the operation of the scraper 23 by electric drive and at the same time removing the applicator 10 from the patient's intestine, thereby improving practicality.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0070] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
