Description

Technical Field

[0001] The invention relates to the technical field of digestive disease treatment and nursing appliances, and in particular to an anorectal drug delivery device for digestive disease nursing auxiliary treatment. Background Art

[0002] Rectal administration methods mainly include retention enema, rectal drip, and suppository insertion. It is a treatment method that delivers drugs into the intestine through the anus, and then enters the blood circulation after being absorbed by the mucosa to treat local or systemic diseases. It is suitable for common diseases in children and can also be used in some gynecological and men's diseases.

[0003] Among them, retention enema method: if the disease is treated by retention enema, the medicine required for treatment is first mixed with the solution. The patient lies flat on the bed after defecation and urination, and the buttocks need to be raised 10cm appropriately. Connect the enema tube to the rubber tube, glass tube and rubber anal tube, apply lubricating oil such as glycerin to the sterilized rubber anal tube, and then exhaust the air in the tube. Slowly insert the anal tube into the patient's anus 10-15cm, and then slowly pour the proportioned liquid medicine into the intestine. The amount of medicine poured in varies according to age, and it is recommended to do it before bedtime. For people with fecal incontinence, retention enema cannot be performed, otherwise it may make the symptoms worse. Therefore, in the actual nursing treatment of anorectal drug administration, it is particularly troublesome, time-consuming and laborious. In the prior art, anorectal drug administration is mostly performed manually, and the insertion depth of the drug tube, the drug injection volume and the injection speed are mostly judged by human experience. That is, skilled medical personnel can control the operation more accurately, while unskilled medical personnel are at a loss. For example, if the drug tube is inserted too deep or the drug is advanced too fast, the patient will feel strong discomfort; if the insertion depth is too shallow or the drug is advanced slowly, the drug cannot enter the patient's body completely and is easy to overflow, which will not have a good drug treatment effect.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0022] Example: Figure 1-Figure 6 As shown: An anorectal drug delivery device for nursing auxiliary treatment of digestive diseases, comprising a support structure 1, a drug delivery structure 2, a drug delivery structure 3 and a driving structure 4; compared with the prior art of direct intubation for pushing, it has the advantages of adjustable insertion depth, adjustable speed of pushing drug solution, and intelligent operation with or without experience. Among them, the support structure 1 includes a bottom plate 11, a base 12 and a lifting member 13. The bottom plate 11 is distributed on the left and right and is a hollow structure. A leg can be set at the lower end of the bottom plate for foot support. The base 12 is connected to the bottom plate 11 through the lifting member 13, so that the base 12 can be raised to a preset height along the bottom plate 11; the base is arranged in the hollow position of the bottom plate. Among them, the lifting member 13 includes an electric hydraulic lifting rod 131, a guide rod 132, and a guide sleeve 133. The electric hydraulic lifting rod 131 is evenly distributed in multiple, one end of which is connected to the base 12 through a flange joint, and the other end is connected to the bottom plate 11 through welding.

[0023] like Figure 4 As shown: wherein, the guide sleeve 133 is fixedly installed on the base 12 in a vertically distributed manner, and the guide rod 132 is fixedly installed on the bottom plate 11, and the guide sleeve 133 is kept matched with the guide rod 132. The purpose of such arrangement is to play a good guiding role and ensure the accuracy of the up and down movement of the base. An LED screen 14 is also provided on one side of the base 12 to maintain signal connection with the liquid level sensor 25. The LED screen has a digital display function for real-time display of the solution inventory in the injection cavity and the amount of medicine pushed in. The end face of the base 12 is provided with a positioning groove 121 adapted to the human body structure, and a disposable coating can also be provided in the positioning groove to ensure single-time use by a single person. Such arrangement improves the comfort of anorectal drug administration and ensures the relaxation of the sphincter. A mounting hole 122 is provided in the center of the positioning groove 121; the purpose of such arrangement is to provide a strong foundation for the subsequent lifting and lowering changes of the injection tube, while ensuring that the injection tube is aligned with the anus.

[0024] like Figure 3As shown: In this embodiment, the dosing structure 2 includes a liquid injection chamber 21 and a stirring member 22. The liquid injection chamber 21 is arranged on the base 12, and is connected to a liquid inlet pipe 23 on one side and a liquid outlet pipe 24 on the other side. The liquid inlet pipe is used for the staff to input and add liquid medicine. A liquid level sensor 25 is also provided in the liquid injection chamber 21; the liquid level sensor is used to monitor the liquid medicine inventory in real time. The stirring member 22 is configured so that the various drugs and solutions added into the liquid injection chamber 21 are uniformly mixed at a preset speed. Specifically, the stirring member 22 includes a stirring motor 221, a stirring shaft 222 and stirring blades 223. The stirring motor 221 is fixedly installed on the base 12 through a bracket, the stirring shaft 222 is vertically distributed in the liquid injection chamber 21, and the stirring blades 223 are uniformly distributed and arranged on the stirring shaft 222. In this way, after the staff prepares the liquid medicine according to the patient's symptoms, they are added into the liquid injection chamber in sequence through the liquid inlet pipe. Then turn on the stirring motor. The stirring motor will drive the stirring shaft and the stirring blades to stir quickly, thereby accelerating the formation of uniformity of the medicine solution to ensure that the medicine solution is better and more reasonably absorbed by the patient, thereby improving the patient's care and rehabilitation progress, and avoiding the problem of the existing technology relying on manual classification and addition of drugs and then manual shaking or stirring operations.

[0025] like Figure 5 As shown: In this embodiment, the drug administration structure 3 includes a sleeve 31 and an injection tube 32. The sleeve 31 is vertically distributed and can be moved up and down in the mounting hole 122; and the sleeve is adapted to be installed at the mounting hole. The injection tube 32 is detachably installed in the sleeve 31 and keeps the infusion connected. A sphere 33 with a through structure is provided at the end of the injection tube 32. The input end of the sleeve 31 is connected to the liquid outlet pipe 24, and a liquid pump 34 is provided at the connection between the liquid outlet pipe 24 and the injection cavity 21, and an electromagnetic switch valve 35 is also provided on the liquid outlet pipe 24; the electromagnetic switch valve serves as an on-off switch for flow transmission. In the preferred embodiment, a backup battery can be provided inside the matrix or connected to the outside through a power cord to ensure the normal use of the internal electrical structure.

[0026] In order to ensure the stability of the connection and installation of the injection tube, it also provides the convenience of easy disassembly and replacement, and provides different injection tubes for subsequent use by different patients. The injection tube is a consumable item as the contact part of anorectal drug administration, which ensures the purpose of medical hygiene. In this embodiment, the injection tube 32 is connected to the sleeve 31 by a connector 36. Specifically, as shown in FIG. Figure 5As shown: the connecting member 36 includes a first pad 361, a second pad 362 and a fastening bolt 363. The first pad 361 is arranged on the injection tube 32, the second pad 362 is arranged on the end of the sleeve 31, and the fastening bolt 363 is used to complete the fastening operation of the first pad 361 and the second pad 362 after the end of the injection tube 32 is inserted into the sleeve 31. A sealing rubber pad 364 is also provided at the connection between the injection tube 32 and the sleeve 31. The purpose of such a setting is to ensure the sealing effect of the connection between the injection tube and the sleeve. A scale line 321 is also provided on the injection tube 32; the purpose of such a setting is to facilitate observation and accurate positioning of the depth of the injection tube inserted into the anus, and the diameter of the ball 33 can be greater than or equal to the diameter of the injection tube 32; the purpose of such a setting is to facilitate insertion into the anus by applying lubricating liquid to the ball and combining the special structure of the ball.

[0027] like Figure 5 As shown: A rotating member 37 is also provided at the bottom end of the sleeve 31, and the rotating member 37 includes a rotating motor 371, a driving wheel 372, and a driven wheel 373. The rotating motor 371 is fixedly installed in the base 12 through a bracket, and the driving wheel 372 is arranged on the output shaft of the rotating motor 371; the driven wheel 373 is sleeved and installed on the sleeve 31, and the two are kept in threaded rotation connection; the driving wheel 372 and the driven wheel 373 are kept in meshing transmission. In the position relationship of the sleeve, the sleeve and the mounting hole are connected by a threaded rotation, which serves the purpose of auxiliary support, and the driven wheel and the sleeve are also connected by a threaded rotation. At the same time, the height of the driven wheel is fixed and can be supported by an auxiliary plate. The auxiliary plate is connected and fixed to the side wall of the base, and a hole is opened in the middle to adapt to the movement of the sleeve. The driven wheel is set on the auxiliary plate and the two are kept relatively rotatable and cannot be relatively moved through the keyway; in this way, when the injection tube needs to be inserted into the patient's anus, the patient's anus and the ball are first smeared with lubricating liquid, and then the rotating motor is turned on, the rotating motor drives the active wheel to rotate, and then the active wheel drives the driven wheel and the sleeve to rotate. The position of the driven wheel remains unchanged, and then the rotation of the driven wheel will drive the sleeve to move up and down. The sleeve is now connected and fixed to the injection tube, which will drive the injection tube to rotate and rise until it enters the preset depth of the anus. The rotation is accompanied by rising, which is more in line with the method of anorectal drug delivery insertion. At the same time, it not only ensures the smoothness of the insertion of the injection tube, but also provides automation conditions, which is more practical. In this embodiment, in order to avoid the patient's rejection psychology, it is ensured that the injection tube rises slowly and the rotation speed of the rotating motor is kept low.

[0028] In this embodiment, the driving structure 4 is configured to drive the mixed liquid medicine from the liquid outlet tube 24 to the sleeve 31 to complete the anorectal drug administration operation in the form of a preset pressure F and a preset pushing speed V. It includes three-level pushing modes of low speed, medium speed and high speed, wherein in the low speed pushing mode, the liquid medicine pushes the preset pressure F1 and the preset pushing speed V1; in the medium speed pushing mode, the liquid medicine pushes the preset pressure F2 and the preset pushing speed V2, and F2>1.2F1, V2>V1; in the high speed pushing mode, the liquid medicine pushes the preset pressure F3 and the preset pushing speed V3, and F3>1.5F2, V3>1.2V2.

[0029] like Figure 3 As shown: Specifically, the driving structure 4 includes a push chamber 41; the push chamber 41 is a columnar structure, the input end of the push chamber 41 is connected to the liquid outlet pipe 24, and the output end is connected to the sleeve 31 through the drainage pipe 42, and the length of the drainage pipe 42 is long enough; the purpose of such a setting is to provide a drainage pipe of sufficient length to provide reserved space for the subsequent sleeve to rise. A one-way valve 43 is also provided on the liquid outlet pipe 24; it is ensured that the liquid medicine can only be transmitted from the injection chamber to the push chamber in one direction to avoid contamination caused by the reflux of the liquid medicine. A pressure control valve 44 is also provided on the drainage pipe 42; at the same time, a one-way valve can also be provided on the drainage pipe, the purpose of such a setting is to avoid residual or overflow of the liquid medicine, and the drainage pipe can only be opened after the push rod moves to change the air pressure change in the push chamber, and the liquid medicine is squeezed into the injection pipe and then discharged to the anus and intestine for liquid medicine treatment. Among them, a push rod 45 and a rubber plug body 46 are also provided in the push chamber 41. The push rod 45 is movably arranged in the push chamber 41. The rubber plug body 46 is fixedly mounted on the end of the pushing rod 45 and is adapted to be mounted in the pushing cavity 41 .

[0030] like Figure 6As shown: wherein, the driving structure 4 also includes a cylinder 47; the output shaft of the cylinder 47 is connected to the push rod 45, and a cylinder speed regulating valve 48 is provided on one side of the cylinder 47. The purpose of such a setting is that by controlling the start and stop of the cylinder, the output arm of the cylinder will drive the push rod to move back and forth, thereby realizing the delivery of the liquid medicine in the push cavity to the injection tube and discharge it into the anorectal cavity of the patient. As for the pushing speed of the liquid medicine, this embodiment plans to use a cylinder speed regulating valve to adjust the cylinder movement speed, thereby realizing different needs of different liquid medicines and different patients to adjust the pushing speed of the liquid medicine. That is, the cylinder has three speeds, corresponding to the low-speed, medium-speed and high-speed three-level pushing modes of the anorectal drug delivery device, wherein the cylinder is pushed at a low speed, and the push rod moves slowly. At this time, in the low-speed pushing mode, the liquid medicine push maintains a preset pressure F1 and a preset pushing speed V1. Wherein the cylinder is pushed at a medium speed, and the push rod moves at an accelerated speed. In this medium-speed pushing mode, the liquid medicine push maintains a preset pressure F2 and a preset pushing speed V2, and F2>1.2F1, V2>V1. The cylinder is pushed at high speed and the push rod moves the fastest. In this high-speed pushing mode, the liquid medicine push maintains the preset pressure F3 and the preset pushing speed V3, and F3>1.5F2, V3>1.2V2.

[0031] In this embodiment, the control method of multiple motors, liquid pumps, liquid level sensors, electromagnetic switch valves and cylinders can be achieved by connecting a control switch to realize multi-key operation, and the control switch is arranged on the outside of the base plate; one-key automatic control can also be achieved by connecting a PLC controller. The control circuit and functional principle of the PLC controller can be realized through simple programming by technicians in this field, which is common knowledge in this field, and this application document is mainly used to protect mechanical devices, so this application will no longer explain the control method and circuit connection in detail.

[0032] The working principle of an anorectal drug delivery device for auxiliary treatment of digestive diseases: in the initial state, the gap between the bottom plate and the base is the smallest, that is, the base is in a low position. First, the staff places the anorectal drug delivery device in a horizontal position on the bed or other treatment point, and instructs the patient to sit in the corresponding positioning slot to adapt to the human body structure. The mounting hole at this time corresponds to the patient's anus. At the same time, the patient's anus and sphere are smeared with lubricating liquid. Next, the staff prepares the type of liquid medicine according to the patient's condition, and then adds it into the injection cavity through the liquid inlet pipe in turn. Then turn on the stirring motor. When the stirring motor starts, it will drive the stirring shaft and stirring blades to mix quickly, speeding up the formation of uniformity of the liquid medicine, so as to ensure that the liquid medicine is better and more reasonably absorbed by the patient, thereby improving the progress of patient care and rehabilitation.

[0033] Next, the staff turns on the rotating motor, which drives the driving wheel to rotate, and then the driving wheel drives the driven wheel and the sleeve to rotate. The sleeve is now connected and fixed to the injection tube, which will drive the injection tube to rotate and rise until it enters the preset depth of the anus. The rotating motor uses a servo control motor to facilitate accurate control of the lifting height (that is, the anorectal insertion depth). At this time, the ball of the injection tube is located at the preset position of the anorectal in the patient's body. Then the medical staff first turns on the liquid pump and the electromagnetic switch valve, sets the input volume, and then the preset amount of liquid medicine begins to enter the push cavity, which plays a good buffering role. Next, turn on the cylinder. The cylinder has three speeds, corresponding to the low-speed, medium-speed and high-speed three-level push modes of the anorectal drug delivery device. Among them, the cylinder is pushed at a low speed, the push rod and the plug body move slowly, and the liquid medicine enters the sleeve from the push cavity through the drainage tube and from the connected injection tube, and the anorectal medication in the patient's body slowly enters. Among them, the cylinder is pushed at a medium speed, and the push rod moves faster. In this medium-speed push mode, the speed of anorectal medication entering the patient's body is significantly increased. The cylinder is pushed forward at a high speed and the push rod moves the fastest. Under this high-speed pushing mode, the anorectal medication enters the patient's body at the fastest speed.

[0034] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
