Description

TECHNICAL FIELD

[0001] The application belongs to the field of negative pressure cleaning equipment, and particularly relates to a pediatric negative pressure gastric lavage device for pediatric nursing. BACKGROUND

[0002] When a pediatrician performs gastric lavage on a child patient, a pediatric negative pressure gastric lavage device needs to be used to perform negative pressure gastric lavage on the patient. Negative pressure gastric lavage refers to a medical method in which a gastric lavage solution prepared by mixing different components in different proportions is injected into the stomach of the patient, so that the poison in the stomach of the patient which has not been absorbed is cleaned and eliminated. After the gastric lavage solution is poured, the gastric lavage solution needs to be pumped out, and the negative pressure gastric lavage work can be completed after such repeated operations for multiple times.

[0003] During the gastric lavage of the child, the injection amount is generally controlled by the doctor during the injection of the gastric lavage solution. The injection amount or flow rate is basically controlled by the doctor according to experience. In some cases, if the flow rate is too large or the injection amount is too large, the stomach of the patient will produce strong discomfort, and the patient will even resist the gastric lavage work. In particular, the child has limited endurance and will resist and swing, and therefore, in order to reduce the resistance of the child, the pediatric negative pressure gastric lavage device for pediatric nursing is provided. SUMMARY

[0004] The application aims to provide a pediatric negative pressure gastric lavage device for pediatric nursing, so as to adjust the flow rate and flow during the injection of the gastric lavage solution and the pumping of the gastric lavage solution, and reduce the probability of discomfort of the child.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the application is as follows: a pediatric negative pressure gastric lavage device for pediatric nursing, comprising a gastric lavage solution tank, a waste liquid tank and a pump assembly. The input end of the pump assembly is communicated with a first reversing valve. One input end of the first reversing valve is communicated with the gastric lavage solution tank, and the other input end of the first reversing valve is communicated with the waste liquid tank and is located at the top of the waste liquid tank. The lower part of the waste liquid tank is communicated with a recovery pipe.

[0006] The output end of the pump assembly is communicated with a second reversing valve. One output end of the second reversing valve is communicated with a gastric lavage pipe, and the other output end of the second reversing valve is communicated with a booster pipe. The booster pipe is communicated with the recovery pipe.

[0007] Further, the gastric lavage pipe and the recovery pipe both pass through the occlusion part.

[0008] Further, the control device is electrically connected with the pump assembly. The first reversing valve and the second reversing valve are both electromagnetic reversing valves, and the control device is electrically connected with the first reversing valve and the second reversing valve.

[0009] Further, the top wall and the bottom wall of the occlusion part are both provided with an occlusion layer. A pressure sensor is arranged in the occlusion layer, and the pressure sensor is electrically connected with the control device.

[0010] Further, the recovery pipe is provided with a first measuring meter, and the gastric lavage pipe is provided with a second measuring meter, and the first measuring meter and the second measuring meter are electrically connected with the controller.

[0011] Further, the booster pipe is communicated with a converging pipe away from the waste liquid tank, the converging pipe is communicated with an exhaust pipe, and the converging pipe has a diameter that is larger at the end close to the booster pipe than at the end away from the booster pipe.

[0012] Further, the bite part comprises a sponge inner layer and a silica gel layer wrapped outside the sponge inner layer.

[0013] The principle and beneficial effects of the above scheme are as follows:(1) The working state of the present application has two, the first working state, when the flow and flow rate of the gastric lavage liquid is large, the child's stomach is not suitable for flushing, the child can bite the gastric lavage pipe through the bite part, so that the gastric lavage liquid flowing into the gastric lavage pipe is reduced and the flow rate is relatively reduced, so that the child adjusts himself. The second working state, the child gradually applies pressure to the bite part, then the pressure sensor transmits the pressure to the controller, and the controller adjusts the power of the pump assembly, so as to reduce the flow and flow rate. Through the combination of the two modes, the flow and flow rate of the gastric lavage liquid in the gastric lavage process are adjusted, and the comfort of the child in the gastric lavage process is improved as much as possible.

[0014] (2) In the present application, the gastric lavage and waste liquid recovery are integrated with intelligent control function, specifically: the controller controls the first reversing valve to communicate with the gastric lavage pipe, at this time the second reversing valve is communicated with the gastric lavage liquid tank, at the same time, the flow and flow rate are monitored by the first measuring meter, and the flow and flow rate are fed back to the controller, the controller adjusts the power of the pump assembly according to the flow and flow rate, so that the stability of the gastric lavage liquid input into the stomach of the child is higher, and the situation of excessive flow or flow rate is reduced, and the resistance behavior of the child due to discomfort is reduced. When the waste liquid is recovered, the controller controls the first reversing valve to communicate with the recovery pipe, and the second reversing valve to communicate with the waste liquid tank, at this time, the controller still controls the pump assembly to work, and the pump assembly is used to draw negative pressure in the waste liquid tank, so that the recovery pipe has negative pressure, so that the waste liquid in the stomach of the child is extracted and recovered, so as to achieve integrated continuous work. Of course, the flow and flow rate information fed back by the second measuring meter is also sent to the controller, and the power of the pump assembly is controlled by the controller. In this way, the pump assembly can be used as a recovery device and a conveying device, reducing the design cost.

[0015] (3) In the present application, in the process of drawing negative pressure in the waste liquid tank by the pump assembly, the gas drawn out is conveyed into the recovery pipe through the booster pipe, the converging pipe and the exhaust pipe, so as to increase the pressure in the recovery pipe to impact and break the larger particles in the stomach, so as to reduce the probability of blockage.

[0016] Additional aspects and advantages of the present application will be given in part in the following description, become apparent from the following description, or be learned by practice of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0024] The specific embodiments are described in detail below:

[0025] ​The reference signs in the drawings of the specification include: a gastric lavage liquid tank 11, a second measuring meter 12, a recovery pipe 13, a bite part 14, a bite layer 141, a gastric lavage pipe 15, a first measuring meter 16, a waste liquid tank 17, a second reversing valve 18, a pump assembly 19, a recovery pipe 21, a first reversing valve 22, a negative pressure pipe 23, a booster pipe 24, a converging pipe 25, and an exhaust pipe 26.

[0026] The present application provides a pediatric negative pressure gastric lavage device for pediatric nursing, substantially as shown in the accompanying drawings Figures 1-4 As shown, the device includes a rack, the rack is provided with a waste liquid tank 17, a gastric lavage liquid tank 11, and a pump assembly 19, and the pump assembly 19 is a centrifugal pump. In this embodiment, the input end of the pump assembly 19 is communicated with the first reversing valve 22, one input end of the first reversing valve 22 is communicated with the gastric lavage liquid tank 11, and the other input end of the first reversing valve 22 is communicated with the waste liquid tank 17 through the negative pressure pipe 23 and the communication position is located at the top of the waste liquid tank 17. As described above, due to the reversing action of the first reversing valve 22, when the pump assembly 19 is communicated with the waste liquid tank 17 through the first reversing valve 22, the pump assembly 19 can draw negative pressure on the waste liquid tank 17 through the first reversing valve 22, and when the pump assembly 19 is communicated with the gastric lavage liquid tank 11 through the first reversing valve 22, the pump assembly 19 draws the gastric lavage liquid in the gastric lavage liquid tank 11 through the first reversing valve 22. The lower part of the waste liquid tank 17 is communicated with the recovery pipe 13.

[0027] The output end of the pump assembly 19 is communicated with the second reversing valve 18, one output end of the second reversing valve 18 is communicated with the gastric lavage pipe 15, and the other output end of the second reversing valve 18 is communicated with the booster pipe 24, the booster pipe 24 is communicated with the recovery pipe 13, the end of the booster pipe 24 away from the waste liquid tank 17 is communicated with the converging pipe 25, the end of the converging pipe 25 away from the booster pipe 24 is communicated with the exhaust pipe 26, and the exhaust pipe 26 is located in the recovery pipe 13. In this embodiment, the diameter of the converging pipe 25 close to the booster pipe 24 is greater than the diameter of the converging pipe 25 away from the booster pipe 24. In this embodiment, the pump assembly 19 delivers gas into the booster pipe 24, the gas is discharged into the converging pipe 25 through the booster pipe 24, and then the gas is pressurized and discharged into the recovery pipe 13 through the exhaust pipe 26. Of course, in order to further increase, the diameter of the exhaust pipe 26 can be smaller than the minimum diameter of the converging pipe 25.

[0028] In this embodiment, the bite part 14 is further included, the recovery pipe 13 and the gastric lavage pipe 15 both pass through the bite part 14, the bite part 14 includes a sponge inner layer and a silica gel layer wrapped outside the sponge inner layer, and the silica gel layer is arranged on the top wall and the bottom wall of the bite part 14. The silica gel layer makes the teeth more comfortable when the child bites.

[0029] As described above, in the present embodiment, the child bites the bite portion 14, and the recovery tube 13 and the gastric lavage tube 15 can extend into the stomach of the child, at this time, the first switching valve 22 is communicated with the pump assembly 19 and the gastric lavage tube 15, and the second switching valve 18 is communicated with the pump assembly 19 and the gastric lavage liquid tank 11, at this time, the gastric lavage liquid is delivered to the stomach of the child through the gastric lavage tube 15 by the pump assembly 19 to perform gastric lavage, if the child patient feels that the flow or flow rate is too large, the child can bite the gastric lavage tube 15, so that the diameter of the gastric lavage tube 15 is reduced, thereby reducing the flow and flow rate, so that the child is not too uncomfortable. When the waste liquid is recovered, the first switching valve 22 is communicated with the pump assembly 19 and the booster pipe 24, and the second switching valve 18 is communicated with the negative pressure pipe 23 and the pump assembly 19, at this time, the pump assembly 19 continuously works to suck negative pressure to the waste liquid tank 17, under the action of negative pressure, the waste liquid in the stomach of the child is recovered through the recovery tube 13, at the same time, the gas discharged by the pump assembly 19 enters the converging pipe 25 through the booster pipe 24 to be boosted, and then enters the recovery tube 13 through the exhaust pipe 26 to boost the recovery tube 13, which can break large particles and reduce the probability of clogging of the recovery tube 13. Of course, if the diameter of the exhaust pipe 26 is smaller than the lowermost diameter of the converging pipe 25, the exhaust pipe 26 will be boosted twice, and the child can also bite the bite portion 14 to reduce the flow and flow rate of the liquid.

[0030] The difference between the above embodiment and the present embodiment is that the first measuring meter 16 is installed on the gastric lavage tube 15, and the second measuring meter 12 is installed on the recovery tube 13, the first switching valve 22 and the second switching valve 18 are both electromagnetic switching valves, and the present embodiment further includes a controller, which can be a computer or a PLC controller and a single-chip microcomputer, etc. The controller is electrically connected with the pump assembly 19, and the controller is electrically connected with the first measuring meter 16 and the second measuring meter 12. In the present embodiment, the power of the pump assembly 19 is controlled by the controller, and the switching work of the first electromagnetic valve and the second electromagnetic valve is also controlled by the controller. The first measuring meter 16 monitors the flow or flow rate information of the gastric lavage liquid in the gastric lavage tube 15, and sends the corresponding information to the controller, and the controller controls the power of the pump assembly 19 based on the above information, thereby reducing the probability of discomfort of the child. Similarly, the controller can also control the power of the pump assembly 19 to regulate the recovery flow and flow rate of the recovered liquid.

[0031] Of course, the input flow and flow rate of the gastric lavage liquid are not fixedly controlled by the controller, and in this case, the child can also control the corresponding by biting the bite portion 14.

[0032] The difference from the above-mentioned embodiments is that, in this embodiment, a pressure sensor is further included, which is installed in the bite part 14 and electrically connected with the controller. When the child is uncomfortable, he will bite, and the more uncomfortable he is, the greater the biting force will be, and thus the greater the force acting on the bite part 14 will be. Therefore, the pressure sensor will send the information to the controller, which will make a judgment based on the information transmitted by the pressure sensor and adjust the power of the pump assembly 19. Of course, such adjustment is also intelligent and can also exert pressure on the recovery tube and the gastric lavage tube in cooperation with the child's autonomous biting, so as to regulate from two aspects.

[0033] The above-mentioned is only an embodiment of the present application, and the common knowledge of specific structures and / or characteristics in the scheme is not described in detail. It should be pointed out that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the patent. The protection scope claimed in this application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
