Description

Technical Field

[0001] The present invention relates to the technical field of pediatric medical devices, and particularly to an intelligent pediatric gastric lavage device. Background Art

[0002] Gastric lavage, as a key medical means to remove poisons, foreign bodies in the stomach or regulate the gastric environment, plays an important role in pediatric emergency treatment. The cases of children being poisoned due to accidental ingestion of drugs, chemicals or foreign bodies have been increasing year by year. Compared with adult gastric lavage, pediatric gastric lavage faces more challenges: children have a small gastric volume, thin and fragile gastric walls, and traditional gastric lavage devices are prone to cause complications such as gastric mucosal injury and gastric perforation due to improper operation.

[0003] Traditional gastric lavage devices (such as electric gastric lavage machines) mostly use rigid materials and large-diameter pipelines. The too thick pipelines are easy to cause throat abrasions and gastric compression. At the same time, the gas-liquid transportation of traditional devices relies on a single pump body, and the coordinated operation of liquid supply, air supply and liquid extraction cannot be achieved. In this way, a single gastric lavage by the gastric lavage machine takes a long time, resulting in an extended poison residue time and an increased risk of toxin absorption. In addition, the non-uniform gas-liquid transportation is easy to cause a sudden change in local gastric pressure, which is prone to cause acute gastric dilatation. Summary of the Invention

[0004] In order to achieve stable and safe gastric lavage operation, the present application provides an intelligent pediatric gastric lavage device.

[0005] The present invention is implemented as follows: An intelligent pediatric gastric lavage device includes a gastric lavage instrument. The gastric lavage instrument includes a device base and an operation instrument. The operation instrument is fixedly installed on the upper end surface of the device base. A plug-in socket is fixedly installed on one side of the device base. A multifunctional shell is detachably installed on the plug-in socket. One end of the multifunctional shell is hermetically connected to the plug-in socket, and the other end of the multifunctional shell is hermetically connected to a partition member. A gastric lavage tube group is installed at the outer end of the partition member. The gastric lavage tube group is hermetically connected to the partition member, and a safety cleaning head is fixedly installed at the outer end of the gastric lavage tube group.

[0006] By adopting the above technical solution, the gastric lavage instrument serves as the main structure of the device. The device base is provided to facilitate the stable placement of the device and ensure the storage, installation, and use of other components. At the same time, an operation instrument is installed above the device base to facilitate the operation of gastric lavage through the operation instrument. A corresponding display screen is set on the operation instrument to facilitate the display of various parameters during the actual operation. By fixedly installing a socket on one side of the device base, it is convenient to connect the multifunctional shell through the socket, which can be quickly installed during actual gastric lavage and easily disassembled when not in use. Through the detachable structure setting of the multifunctional shell, it is convenient to clean and replace the device, reducing the risk of cross-infection. By hermetically connecting a partition at the other end of the multifunctional shell, the partition is provided to facilitate the cooperative connection between the multifunctional shell and the gastric lavage tube group. At the same time, the partition is provided to ensure that the gastric lavage tube group can be hermetically shielded when not installed, avoiding pollution inside the pipeline of the gastric lavage tube group and increasing the safety of device use. At the same time, the setting of the gastric lavage tube group and the safety cleaning head can improve the safety and comfort of gastric lavage and reduce the damage to the stomach of children.

[0007] Further, the device base includes a main seat box, a retractable storage shell, a liquid supply shell, and a waste liquid shell. The storage shell is installed in the middle of the front end face of the main seat box. The liquid supply shell and the waste liquid shell are respectively arranged on both sides of the storage shell. Operation handles are fixedly installed on the outer side surfaces of the storage shell, the liquid supply shell, and the waste liquid shell. A micro air pump is installed in the storage shell, a liquid supply pump is installed in the liquid supply shell, and a liquid extraction pump is installed in the waste liquid shell.

[0008] By adopting the above technical solution, by designing the device base into a structure that combines the main seat box, the storage shell, the liquid supply shell, and the waste liquid shell, it is ensured that the main seat box can be used as the main structure during use. At the same time, the device base adopts a retractable design for the storage shell, the liquid supply shell, and the waste liquid shell, which is convenient for maintaining and replacing the components inside the device. Through the setting of the storage shell, it is convenient to disassemble the multifunctional shell, the partition, the gastric lavage tube group, and the safety cleaning head when not in use, and then store them in the main seat box, which is convenient for storage and access. The setting of the micro air pump, the liquid supply pump, and the liquid extraction pump can realize the transportation of gas and liquid and the extraction of waste liquid, improving the efficiency of gastric lavage.

[0009] Further, the socket includes a seat plate, an inner insertion shell, and an air supply pipe connected to the micro air pump. There are two groups of inner insertion shells, and the two groups of inner insertion shells are symmetrically installed on the outer side surface of the seat plate. The two groups of inner insertion shells are respectively connected to the liquid supply pump and the liquid extraction pump. A plug-in slot is arranged between the two groups of inner insertion shells. An arc plate is integrally formed on the inner insertion shell. The air supply pipe is arranged between the two arc plates on both sides, and the inner insertion shell and the air supply pipe are both fixedly connected to the seat plate.

[0010] By adopting the above technical solution, the socket is designed as a structure in which a base plate, an inner insertion shell and a supply air pipe are matched. When in use, it is convenient to stably install two groups of inner insertion shells through the base plate, and the two groups of inner insertion shells are respectively connected to a liquid supply pump and a liquid extraction pump, so as to realize the purpose of supplying liquid to the stomach and sucking liquid from the stomach during the gastric lavage process. Moreover, the two channels can be separated from each other to ensure safer use during gastric lavage. In addition, the structural design of the insertion slot arranged between the two groups of inner insertion shells enables the multi-functional shell to be quickly inserted when in use, and can also ensure their tight connection during use. At the same time, an arc-shaped plate is integrally formed on the inner insertion shell to meet the effective layout of the supply air pipe. When the multi-functional shell is inserted on the inner insertion shell, it can be connected to the supply air pipe at the same time, which is very convenient to use. The setting of the supply air pipe provides a channel for the transmission of gas, and can timely supplement air pressure during the gastric lavage process, avoiding the situation of nausea in children during the gastric lavage process and ensuring the smooth progress of the gastric lavage process.

[0011] Further, the multi-functional shell includes a main frame shell, a partition frame and a connection head for inserting and installing a partition member. One end of the main frame shell is sleeved and fixed on the outer side surface of the inner insertion shell, and the connection head is integrally formed at the other end of the main frame shell.

[0012] By adopting the above technical solution, the design of the main frame shell and the connection head of the multi-functional shell facilitates the connection with the socket and the partition member, realizes the sealed connection between the components of the equipment, prevents gas and liquid leakage, and at the same time divides the main frame shell and the connection head into two independent parts through the partition frame, facilitating the independent use of liquid supply and liquid suction at the same time, so that it is more flexible to use during the cleaning process.

[0013] Further, the partition frame includes a main partition board and a sub-partition board. The main partition board is fixedly installed in the main frame shell, the sub-partition board is fixedly installed in the connection head, and the sub-partition board is integrally formed at one end of the main partition board. A transverse board is fixedly installed in the middle of the outer end of the sub-partition board, and ejector rods are fixedly installed at both ends of the transverse board.

[0014] By adopting the above technical solution, the main partition board and the sub-partition board of the partition frame can separate the space inside the multi-functional shell, ensure the independent transmission of liquids on both sides, and avoid mutual interference. The setting of the transverse board and the ejector rods is used to cooperate with the partition member. After the partition member is inserted and installed on the multi-functional shell, the channels at both ends can be automatically opened, and the channels can be automatically closed when not in use, which is very convenient to use.

[0015] Further, a sleeve part for sealing connection with the supply air pipe is arranged at one end of the main partition board facing the inner insertion shell. A connecting air pipe is fixedly installed on the upper end surface of the main frame shell. One end of the connecting air pipe is hermetically connected to the sleeve part, and a matching pipe head is arranged at the other end of the connecting air pipe.

[0016] By adopting the above technical solution, through the arrangement of the sleeve part on the main partition plate and the connecting air pipe, the connection between the air supply pipe and the air supply hose in the gastric lavage tube group is realized, providing an independent channel for the transportation of gas, and ensuring that the pressure in the stomach can be better maintained through gas supply during the gastric lavage process. Specifically, auxiliary components such as a pressure sensor can be installed on the safety cleaning head to detect the gastric pressure, or adaptive air supplement operation can be carried out according to the liquid delivery speed.

[0017] Furthermore, the partition member includes an inner pipe sleeve and an outer ring cover for installing the gastric lavage tube group. The inner pipe sleeve is inserted and fixed in the connecting head, and a middle partition plate is integrally formed in the middle of the inner pipe sleeve. A partition seat is fixedly installed in the middle of the outer side of the outer ring cover. Two groups of flip-up and open self-sealing covers are symmetrically installed on both sides of the partition seat. A number of elastic compression springs for pressing the self-sealing covers are also installed on the partition seat, and a partition insertion piece is fixedly installed in the middle of the partition seat.

[0018] By adopting the above technical solution, the design of the inner pipe sleeve and the outer ring cover of the partition member facilitates the connection with the multi-functional shell and the gastric lavage tube group. The setting of the self-sealing cover and the elastic compression spring can automatically seal when the gastric lavage tube group is not connected, preventing external environment from polluting the inside of the pipeline and improving the safety of the equipment. The internal space is separated by integrally forming a middle partition plate in the middle of the inner pipe sleeve, and the partition insertion piece fixedly installed in the middle of the partition seat ensures that the two sides of the space can be separated and used for diversion when the gastric lavage tube group is connected.

[0019] Furthermore, the gastric lavage tube group includes a drainage shell, a partition angle plate and a double-channel hose. The drainage shell is buckled on the outer side of the outer ring cover, and a connecting seat for sealing and fixing with the outer ring cover is arranged on the drainage shell. The partition angle plate is fixedly installed in the middle of the drainage shell, and a sealed slot for inserting the partition insertion piece is opened on the partition angle plate. The double-channel hose is hermetically connected to one end of the drainage shell, and an air supply hose is arranged in the double-channel hose. An outer joint corresponding to the matching pipe head is fixedly installed on the outer side of the drainage shell, and the lower end of the outer joint is hermetically connected to the air supply hose.

[0020] By adopting the above technical solutions, the design of the drainage shell, partition angle plate and double-channel hose of the gastric lavage tube group realizes the independent transportation of gas and liquid and the extraction of waste liquid. The setting of the external joint and the air supply hose ensures the normal supply of gas and liquid and improves the efficiency of gastric lavage. By designing the gastric lavage tube group into a structure in which the drainage shell, partition angle plate and double-channel hose cooperate with each other, it is convenient to guide the liquid through the drainage shell during use. The drainage shell adopts a conical structure, and the partition angle plate can divide the drainage shell into two parts of the diversion structure. By opening a sealing slot on the partition angle plate, it is convenient for the partition insert to be inserted and installed. By arranging the air supply hose in the double-channel hose, it is ensured that the air supply to the stomach can be stably carried out to balance the gastric pressure during the process of liquid transportation and extraction without affecting it, and the setting of the external joint ensures that the matching pipe head and the air supply hose can be flexibly disassembled and assembled.

[0021] Further, the safety cleaning head includes a gastric intubation head, a central tube and a shunt tube. The central tube is fixedly installed at the center of the gastric intubation head, and a plurality of groups of annular shells are evenly arranged on the outer side surface of the gastric intubation head. A plurality of gas-liquid outlets are evenly arranged on the outer side surface of the annular shell along the circumferential direction. The shunt tube is connected between the annular shell and the central tube, and both ends of the shunt tube are hermetically connected to the central tube and the annular shell respectively.

[0022] By adopting the above technical solutions, the design of the gastric intubation head, central tube and shunt tube of the safety cleaning head can evenly transport gas and liquid to the stomach of the child, improving the effect of gastric lavage. And. The setting of the annular shell and the gas-liquid outlet enables the gas and liquid to be more widely distributed in the stomach, enhancing the cleaning effect.

[0023] Further, the gastric intubation head includes an outer tube shell, an annular angle shell and a connecting nozzle. The annular angle shell is evenly arranged on the outer side surface of the outer tube shell, and one end of the annular angle shell is fixedly connected to the outer tube shell. The other end of the annular angle shell is provided with an inclined surface feeding groove. A plurality of liquid suction holes are evenly arranged on the outer side surface of the outer tube shell along the circumferential direction. The liquid suction holes are arranged in the middle of the annular angle shell. One end of the outer tube shell is a closed structure, and the connecting nozzle is fixedly installed at the other end of the outer tube shell.

[0024] By adopting the above technical solutions, the design of the outer tube shell, annular angle shell and liquid suction holes of the gastric intubation head can effectively absorb the waste liquid in the stomach. At the same time, the setting of the inclined surface feeding groove facilitates the entry of gas and liquid, improving the efficiency of gastric lavage. By setting the annular angle shell, it is ensured that the liquid is not absorbed by a single liquid suction hole during liquid suction, but by an annular adsorption groove, which can avoid damage to the stomach during the liquid suction process. Moreover, the outer end of the annular angle shell is set as an arc structure to further increase the safety during the adsorption process. By setting the liquid suction holes in the middle of the annular angle shell, a stable and uniform adsorption force is provided for the annular angle shell to ensure the safety during the waste liquid extraction process.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention adopts a detachable multi-functional shell design, which facilitates the cleaning and replacement of the device and reduces the risk of cross-infection. At the same time, the connection between the components is tight, and the sealing performance is good, which can effectively prevent gas-liquid leakage. Through the coordinated operation of the micro air pump, liquid supply pump and liquid extraction pump, the efficient transportation of gas-liquid and the rapid extraction of waste liquid can be achieved, improving the efficiency of gastric lavage. The safety cleaning head adopts a special annular corner shell adsorption structure to ensure greater safety during the extraction of waste liquid and reduce the irritation to the stomach of children. At the same time, the design of the gastric lavage tube group can ensure the uniform transportation of gas-liquid and the effective extraction of waste liquid, improving the safety and comfort of gastric lavage.

A number of elastic compression springs 45 for pressing the self-sealing covers 44 are also installed on the partition seat 43, and a partition insert piece 431 is fixedly installed in the middle of the partition seat 43. The inner pipe sleeve 41 and the outer ring cover 42 of the partition member 4 can be made of polyvinyl chloride (PVC) material, which has good processing performance and chemical corrosion resistance. The design of the inner pipe sleeve 41 and the outer ring cover 42 of the partition member 4 facilitates the connection with the multifunctional shell 3 and the gastric lavage tube set 5. The setting of the self-sealing covers 44 and the elastic compression springs 45 can automatically seal when the gastric lavage tube set 5 is not connected, preventing external environment from polluting the inside of the pipeline and improving the safety of the equipment. The internal space is partitioned by integrally forming the middle partition plate 411 in the middle of the inner pipe sleeve 41, and the partition insert piece 431 fixedly installed in the middle of the partition seat 43 ensures that the spaces on both sides can be partitioned and used for diversion when the gastric lavage tube set 5 is connected.

The gastric lavage tube group 5 is hermetically connected to the partition member 4, and a safety cleaning head 6 is fixedly installed at the outer end of the gastric lavage tube group 5.

[0038] Refer to Figure 11 、 Figure 12 and Figure 13As shown, the safety cleaning head 6 includes a gastric intubation head 61, a central tube 62, and a shunt tube 63. The central tube 62 is fixedly installed at the center of the gastric intubation head 61, and several groups of annular shells 64 are evenly arranged on the outer side surface of the gastric intubation head 61. A number of gas-liquid outlets 640 are evenly opened on the outer side surface of the annular shell 64 along the circumferential direction. The shunt tube 63 is connected between the annular shell 64 and the central tube 62, and both ends of the shunt tube 63 are hermetically connected to the central tube 62 and the annular shell 64 respectively. The gastric intubation head 61 can be made of medical-grade rubber material, which is soft in texture and can reduce the irritation to the stomach of the child. The design of the gastric intubation head 61, the central tube 62, and the shunt tube 63 of the safety cleaning head 6 can evenly transport gas-liquid to the stomach of the child, improving the effect of gastric lavage. And. The setting of the annular shell 64 and the gas-liquid outlet 640 enables the gas-liquid to be more widely distributed in the stomach, enhancing the cleaning effect.

[0039] Refer to Figure 11 、 Figure 12 and Figure 13 As shown, the gastric intubation head 61 includes an outer tube shell 611, an annular corner shell 612, and a connecting nozzle 613. The annular corner shells 612 are evenly arranged on the outer side surface of the outer tube shell 611, and one end of the annular corner shell 612 is fixedly connected to the outer tube shell 611. The other end of the annular corner shell 612 is provided with an inclined surface feeding groove 610. A number of liquid suction holes 614 are evenly arranged on the outer side surface of the outer tube shell 611 along the circumferential direction.

One end of the outer tube shell 611 is a closed structure, and the connecting nozzle 613 is fixedly installed at the other end of the outer tube shell 611. The design of the outer tube shell 611, the annular corner shell 612, and the liquid suction holes 614 of the gastric intubation head 61 can effectively suck the waste liquid in the stomach. At the same time, the setting of the inclined surface feeding groove 610 facilitates the entry of gas-liquid and improves the efficiency of gastric lavage. By setting the annular corner shell 612, it is ensured that during liquid suction, it is not a single liquid suction hole 614 for absorption, but an annular adsorption groove, which can avoid damage to the stomach during the liquid suction process. Moreover, the outer end of the annular corner shell 612 is set as an arc structure to further increase the safety during the adsorption process. By setting the liquid suction holes 614 in the middle of the annular corner shell 612, a stable and uniform adsorption force is provided for the annular corner shell 612 to ensure the safety during the waste liquid extraction process. Working principle: During actual use, one end of the main frame shell 31 of the multifunctional shell 3 is sleeved and fixed on the outer side surface of the inner insertion shell 22, so that the sleeve part 323 is hermetically connected to the air supply pipe 23. The inner tube sleeve 41 of the partition member 4 is inserted and fixed in the connecting head 33. The drainage shell 51 of the gastric lavage tube group 5 is buckled on the outer side surface of the outer ring cover 42, so that the partition insertion piece 431 is inserted into the sealing slot 521, and the outer joint 512 is connected to the mating pipe head 312. The safety cleaning head 6 is fixedly installed at the outer end of the gastric lavage tube group 5.

[0040] During the gastric lavage operation, an appropriate amount of cleaning liquid is added to the liquid supply housing 113. The safety cleaning head 6 is slowly inserted into the stomach of the child. The operating instrument 12 is started to control the operation of the micro air pump, liquid supply pump and liquid extraction pump. The liquid supply pump delivers the cleaning liquid to the safety cleaning head 6 through the inner insertion housing 22 and the gastric lavage tube set 5. The micro air pump delivers gas to the safety cleaning head 6 through the gas supply pipe 23, connecting gas pipe 311 and gas supply hose 54. The cleaning liquid and gas enter the child's stomach through the gas-liquid outlet 640 for cleaning. The liquid extraction pump extracts the waste liquid in the stomach through the gastric lavage tube set 5 and the inner insertion housing 22 into the waste liquid housing 114. After the gastric lavage is completed, the operating instrument 12 is turned off and the safety cleaning head 6 is slowly withdrawn.

[0041] When not in use, the equipment needs to be cleaned and maintained.
