Description

Technical Field

[0001] The invention relates to the technical field of negative pressure gastric lavage, in particular to a pediatric negative pressure gastric lavage device for pediatric nursing. Background Art

[0002] When pediatricians perform gastric lavage on children, they need to use a pediatric negative pressure gastric lavage device. Negative pressure gastric lavage refers to a medical method in which a gastric lavage solution made of drugs with different ingredients in different proportions is injected into the patient's stomach to clean and eliminate unabsorbed toxins in the patient's stomach. After the gastric lavage solution is injected, it needs to be extracted, and this can be repeated many times to complete the negative pressure gastric lavage work.

[0003] During the gastric lavage process for children, when injecting the gastric lavage fluid, the control of the injection amount is generally performed by the doctor, and the injection amount or flow rate is basically based on experience. In some cases, such as excessive flow rate or excessive injection amount, the patient's stomach will feel strongly uncomfortable, and even resist the gastric lavage work, especially when the child's tolerance is limited, the child will resist and swing. In the related art, when the flow rate and flow rate of the gastric lavage fluid are large, making the child's stomach lavage uncomfortable, the child can bite the gastric lavage tube through the bite portion, so that the gastric lavage fluid flowing into the gastric lavage tube is reduced and the flow rate is relatively reduced, so that the child can adjust it by himself or transmit the pressure to the controller through the pressure sensor, and the controller adjusts the power of the pump assembly, so as to achieve the purpose of reducing the flow rate and flow rate. Through the combination of the two modes, the flow rate and flow rate of the gastric lavage fluid during the gastric lavage process are conveniently adjusted. Although the flow rate and flow rate of the gastric lavage fluid can be adjusted, in actual use, when the child is uncomfortable, he will not only bite the bite portion tightly, but also loosen it, causing the position of the bite portion to shift, affecting the subsequent negative pressure flushing, which has certain limitations and is inconvenient to use.

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] 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.

[0038] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. 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.

[0040] During gastric lavage, gastric lavage fluid made of drugs with different ingredients in different proportions is injected into the patient's stomach to clean and eliminate unabsorbed poisons in the patient's stomach. After the gastric lavage fluid is injected, it is extracted. This process can be repeated several times to complete the negative pressure gastric lavage.

[0041] In the related art, when the flow rate and flow velocity of the gastric lavage fluid are large and make gastric flushing uncomfortable for children, the children can bite the gastric lavage tube through the bite portion to reduce the gastric lavage fluid flowing into the gastric lavage tube and reduce the flow velocity relatively. In this way, the children can adjust themselves or transmit the pressure to the controller through the pressure sensor, and the controller adjusts the power of the pump assembly to achieve the purpose of reducing the flow rate and flow velocity. Through the combination of the two modes, the flow rate and flow velocity of the gastric lavage fluid during gastric lavage are convenient to adjust. Although the flow rate and flow velocity of the gastric lavage fluid can be adjusted, in actual use, when the children feel uncomfortable, they will not only bite the bite portion tightly, but also loosen it, causing the position of the bite portion to shift, affecting the subsequent negative pressure flushing, which has certain limitations and is inconvenient to use.

[0042] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a pediatric negative pressure gastric lavage device for pediatric care. When it is needed, only the water pump 14 needs to be turned on, and then the flow direction is switched by using the reversing valve 1 21 and the reversing valve 2 24. The medical staff observes the gastric lavage of the child and manually turns the valve 23, cooperates with the pressure difference bypass valve and the pipeline 5 26 to adjust the flow rate and flow velocity, and connects with the child's head through the strap 18 to play a limiting role, which is more convenient and quick, and improves the convenience of the device.

[0043] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0044] Combination Figure 1-Figure 4, the embodiment of the present application provides a pediatric negative pressure gastric lavage device for pediatric care, including a main body component 1; the main body component 1 includes: a box body 11 with a medicine box 12 fixedly connected to the inner side thereof; a recovery box 13 is arranged on the inner side of the box body 11; a water pump 14 is fixedly connected to the box body 11; a pipe 15 is arranged at the water outlet of the water pump 14; a bite block 16 is arranged on the outer side of the pipe 15; a pipe 2 17 is arranged at the water inlet of the water pump 14, and one end of the pipe 2 17 is connected to the medicine box 12; a strap 18 is arranged on the outer side of the bite block 16; an adjustment component 2 is arranged on the pipe 15; the adjustment component 2 includes: a reversing valve 1 21 is arranged on the pipe 2 17; a pipe 3 22 is arranged on the reversing valve 1 21, and the other end of the pipe 3 22 passes through the box body 11 and passes through the bite block 16 at the same time as the pipe 15; a valve 23 is arranged on the outer side of the pipe 15; a reversing valve 2 24 is arranged on the outside of the pipeline 15; pipeline 4 25 is arranged on one side of the recovery box 13, and the pipeline 4 25 is connected to the reversing valve 24; pipeline 5 26 is arranged on the outside of the pipeline 15, and one end of the pipeline 5 26 is connected to the medicine box 12; the pressure difference bypass valve 27 is arranged on the pipeline 5 26; a cutting assembly 5 is arranged in the pipeline 2 17; the cutting assembly 5 includes: a mounting rod 51 fixedly connected to the pipeline 2 17; a rotating rod 52 is rotatably connected to the mounting rod 51; a blade 53 is fixedly connected to the outside of the rotating rod 52; a steering gear 54 is fixedly connected to the mounting rod 51, and the rotating rod 52 is connected to the steering gear 54; an adjusting rod 55 is arranged on the steering gear 54, and the top of the adjusting rod 55 passes through the pipeline 2 17; a connecting rod 6 is fixedly connected to the water pump 14, and the rotating rod 52 is connected to the connecting rod 6 through a sliding assembly 7.

[0045] During use, after placing the box body 11 at the designated position, inject the gastric lavage fluid into the medicine box 12, then insert the pipe 15 into the patient's stomach, the patient bites the bite block 16, and puts the bandage 18 on the head, and then turns on the water pump 14, so that the water pump 14 draws the gastric lavage fluid in the medicine box 12 into the pipe 15 through the pipe 2 17, and then delivers it to the patient's stomach. After the patient's gastric lavage operation, use the reversing valve 1 21 and the reversing valve 2 24 to switch the connection between pipe 3 22 and the medicine box 12 to the connection between pipe 3 22 and pipe 2 17, and to connect pipe 1 15 to the water pump 14, and then switch to pipe 4 25 connected to the water pump 14, and then turn on the water pump 14 again, so that it applies negative pressure suction to pipe 3 22 through pipe 2 17, and pipe 3 22 and pipe 1 15 are inserted into the patient's stomach at the same time in advance, and the negative pressure suction draws the gastric lavage fluid after flushing the stomach into the pipe The gastric lavage solution in pipe 1 22 is discharged into the recovery box 13 after passing through the water pump 14 and pipe 3 22 to complete the gastric lavage. During the gastric lavage, the medical staff observes the patient's condition to determine whether it is necessary to turn the valve 23 to adjust the flow of the gastric lavage solution in pipe 1 15, and the flow rate can be adjusted by adjusting the power of the water pump 14. Adjusting the power of the water pump 14 belongs to the prior art and will not be described in detail (a pressure sensor is provided on the bite block 16, and a controller is provided in the device to adjust the power of the water pump 14). When the valve 23 is turned to reduce the flow in pipe 1 15, the pressure in pipe 1 15 increases because the power of the water pump 14 remains unchanged. At this time, the pressure difference bypass valve 27 is automatically opened to allow part of the gastric lavage solution to flow back to the medicine box 12 through pipe 5 26. Finally, the power of the water pump 14 is adjusted to achieve the change of the flow rate while reducing the flow rate.

[0046] When the used gastric lavage liquid is recovered, the adjusting rod 55 is manually rotated to drive the rotating rod 52 and the blade 53 to rotate on the mounting rod 51 through the steering gear 54, and the impurities in the gastric lavage liquid are cut by the blade 53, which is convenient for subsequent processing and can prevent pipeline blockage;

[0047] It is also possible to connect the water pump 14 to the rotating rod 52 by using the sliding assembly 7, so that when the water pump 14 is turned on, the rotating rod 52 can be driven to rotate by the connecting rod 6 and the sliding assembly 7, so that the water pump 14 and the blade 53 can work at the same time. It is also possible to separate the water pump 14 from the rotating rod 52 by using the sliding assembly 7, so that the water pump 14 and the blade 53 can work separately without affecting normal use.

[0048] Specifically, the models of the reversing valve 1 21 and the reversing valve 2 24 are HV-02 / 03 / 04, and the reversing methods thereof belong to the prior art, so they will not be described in detail.

[0049] The model of the pressure differential bypass valve 27 is DN15-50, which belongs to the prior art, so it will not be described in detail;

[0050] The electric push rod 71 is connected to a wireless controller and is opened and closed by an external wireless remote control, such as a DC wireless controller of model 0juQZ082, which belongs to the prior art and will not be described in detail.

[0051] In some embodiments, the sliding assembly 7 includes: an electric push rod 71 fixedly connected to the inner side of the steering gear 54; a connecting block 72 fixedly connected to the output end of the electric push rod 71; a ring body 73 rotatably connected to the outer side of the rotating rod 52, and the rotating rod 52 is a telescopic rod, divided into an inner rod and an outer rod, the ring body 73 is arranged on the outer side of the inner rod, and the outer rod is rotatably connected to the mounting rod 51; a gear 74 is rotatably connected to one end of the rotating rod 52; and a slot 75 is opened at one end of the connecting rod 6.

[0052] When in use, the electric push rod 71 is turned on, so that its output end drives the connecting block 72 and the ring body 73, so that the ring body 73 drives the inner rod in the rotating rod 52 to slide, and pushes the gear 74, so that the gear 74 is engaged with the connecting rod 6 to complete the connection, otherwise the separation is achieved. After the connection, the water pump 14 is turned on, so that the central axis of the centrifugal blade drives the inner rod in the rotating rod 52 to rotate through the connecting rod 6, so that the inner rod drives the outer rod and the blade 53 to rotate, and the ring body 73 is rotationally connected with the rotating rod 52, which does not affect the normal rotation of the rotating rod 52.

[0053] In some embodiments, a one-way valve 3 is provided on the pipe 5 26 to prevent the liquid in the medicine box 12 from flowing back.

[0054] In some embodiments, a shell 4 is provided on the outside of the tube 15 so that the tube 15 and the tube 3 22 can be inserted into the stomach at the same time.

[0057] When in use, after the spray pipe 91 is connected to an external water source, water enters the spray head 92 through the spray pipe 91 , and the inner side of the recovery box 13 is cleaned through the spray head 92 .

[0058] In some embodiments, a mounting plate 81 is provided on one side of the door body 8, and a baffle 82 is slidably connected to the mounting plate 81, and a fixing bolt 83 is threadedly connected to the baffle 82. When in use, when the door body 8 is opened, the baffle 82 is disengaged from the spray head 92, thereby facilitating subsequent spraying operations, or by rotating the fixing bolt 83 to cancel the fixation of the baffle 82, the baffle 82 is pushed, and the height of the baffle 82 is adjusted, so that when the door body 8 is closed, the baffle 82 does not contact the spray head 92 and does not affect the spraying.

[0059] In some embodiments, the bottom of the shower head 92 is higher than the pipe 25 to prevent the recovered mixture from contacting the shower head 92.
