TECHNICAL FIELD
[0001] The present application relates to the technical field of medical care, in particular to a gastrointestinal nursing decompression device applied to gastroenterology nursing. BACKGROUND
[0002] The gastrointestinal nursing decompression device is a medical instrument applied to gastroenterology clinical nursing, which mainly generates negative pressure suction through a gastric tube to guide the contents such as liquid and gas accumulated in the gastrointestinal tract of a patient out of the body, so as to reduce the pressure in the gastrointestinal tract, relieve symptoms such as abdominal distension and vomiting, promote the recovery of gastrointestinal function, and is commonly used for the auxiliary treatment of postoperative gastrointestinal decompression, intestinal obstruction, acute pancreatitis and other diseases.
[0003] In the existing device, the negative pressure generating component and the liquid and gas storage component are designed in one body and are disposable, so that the whole device is discarded after use, which not only increases the medical cost, but also has the risk of cross infection due to the inability to separate and clean. Although some improved devices attempt to separate the structure, the negative pressure conduction path design is unreasonable, and air leakage phenomenon is easy to occur, which leads to poor negative pressure stability and affects the decompression effect. The existing devices rely on fixed elastic elements to generate a single negative pressure value, and the suction strength cannot be adjusted according to the patient's condition, which is easy to cause damage to the gastrointestinal mucosa due to excessive negative pressure, or incomplete drainage due to insufficient negative pressure. A few devices with adjustment function need additional electronic components, which not only increases the cost, but also is not suitable for primary medical scenes and emergency use. In addition, the liquid and residual liquid are inconvenient to handle. The traditional device needs to interrupt the decompression operation to pour the stored liquid, and frequent interruption will cause the pressure in the gastrointestinal tract to fluctuate, aggravating the patient's discomfort. At the same time, the connection between the gastric tube and the storage component is easy to leave liquid, which is easy to cause liquid leakage and pollution when disassembled, increasing the operation burden of medical staff. Although some devices are provided with a liquid discharge valve, external air is easy to enter and destroy the negative pressure environment during the liquid discharge process, and the negative pressure needs to be manually established again, which is complicated to operate.

DETAILED DESCRIPTION
[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0030] Example 1, refer to Figure 1 - Figure 3 , Figure 5 and Figure 7 - Figure 9For the first embodiment of the present application, a gastrointestinal nursing decompression device applied to gastrointestinal nursing is provided, comprising a presser 1, a reset spring 2 fixedly connected in the presser 1, an exhaust assembly 5 fixedly connected to the inner wall of the top of the presser 1, a detachment assembly 8 fixedly connected to the outer wall of the bottom of the presser 1, a flow guide assembly 7 inserted into the inner wall of the detachment assembly 8, a connecting assembly 4 inserted into the inner wall of the flow guide assembly 7, a residual contraction assembly 6 fixedly connected to the other end of the connecting assembly 4, and a storage barrel 3 fixedly connected to the residual contraction assembly 6; the exhaust assembly 5 comprises a fixed tube 51 fixedly connected to the inner wall of the top of the presser 1, a ventilation slot 56 opened in the side wall of the fixed tube 51, a positioning plate 52 fixedly connected to the inner wall of the fixed tube 51, a connecting block 53 fixedly connected to the inner wall of the top of the fixed tube 51, a positioning spring 54 fixedly connected to the side wall of the connecting block 53, and a sliding block 55 fixedly connected to the other end of the positioning spring 54; the flow guide assembly 7 comprises an insertion tube 71 slidingly connected to the inner wall of the presser 1, a spiral guide tube 72 fixedly connected to the inner wall of the insertion tube 71, an air outlet slot 74 opened in the inner wall of the bottom of the insertion tube 71, an expansion component 73 fixedly connected to the inner wall of the insertion tube 71, and a positioning component 75 fixedly connected to the outer part of the bottom of the insertion tube 71; the residual contraction assembly 6 is used for sucking out the residual liquid of the stomach tube in the patient in cooperation with the storage barrel 3, the detachment assembly 8 is used for assisting the fixation of the flow guide assembly 7, and the connecting assembly 4 is used for connecting the inside of the presser 1 and the inside of the storage barrel 3. The expansion component 73 comprises an expansion rod 733 fixedly connected to the inner side wall of the insertion tube 71, a second stretching spring 734 sleeved to the outer part of the expansion rod 733, a connecting shaft 732 fixedly connected to the outer wall of the second stretching spring 734, and a movable plate 731 fixedly connected to the outer wall of the connecting shaft 732.
[0031] The positioning component 75 comprises an insertion block 751 fixedly connected to the inner wall of the insertion tube 71, an active cavity 752 opened in the inner wall of the insertion block 751, elastic sheets 753 fixedly connected to the inside of the active cavity 752, a connecting buckle 754 fixedly connected to the outer wall of the elastic sheet 753, and a positioning block 755 fixedly connected to the outer wall of the connecting buckle 754.
[0032] The connecting assembly 4 comprises a first elbow pipe 41 inserted into the inner wall of the insertion tube 71, a corrugated pipe 42 fixedly connected to the outer wall of the first elbow pipe 41, an insertion pipe 43 fixedly connected to the end of the corrugated pipe 42 away from the first elbow pipe 41, and an insertion rod 44 fixedly connected to the inner wall of the insertion pipe 43.
[0033] Specifically, before use, the device is assembled and positioned, and the bottom of the insertion tube 71 in the flow guide assembly 7 is aligned with the insertion slot 82 in the inner wall of the support 81 of the escape assembly 8. During the insertion process, the positioning component 75 on the inner wall of the insertion tube 71 plays a role, and the insertion block 751 enters the support 81 with the insertion tube 71. The elastic sheet 753 in the movable cavity 752 of the inner wall of the insertion block 751 is deformed due to extrusion, driving the outer wall connecting buckle 754 and the positioning block 755 to pop out, and the outer wall connecting buckle 754 and the positioning block 755 are clamped in the corresponding clamping groove in the inner wall of the support 81, preliminarily fixing the insertion tube 71 and preventing it from falling off during use.
[0034] Next, the connection assembly 4 is used to connect the presser 1 and the storage barrel 3, one end of the first elbow pipe 41 of the connection assembly 4 is inserted into the preset interface on the inner wall of the insertion tube 71, the other end is connected to the insertion pipe 43 through the corrugated pipe 42, and the insertion rod 44 on the inner wall of the insertion pipe 43 is inserted into the preset communication port on the top of the storage barrel 3, thereby completing the construction of the airflow channel between the inside of the presser 1 and the inside of the storage barrel 3. Finally, one end of the patient's stomach tube is connected to the stomach tube interface on the side wall of the storage barrel 3, and the other end is placed into the patient's gastrointestinal tract, and the device enters the standby state.
[0035] When the presser 1 is pressed, the internal volume of the presser 1 is reduced, the internal gas is pressurized and flows to the exhaust assembly 5, the gas enters the fixed pipe 51 on the top inner wall of the presser 1, due to the increase in pressure, the sliding block 55 on the inner wall of the fixed pipe 51 is driven to move outward, overcoming the elastic force of the positioning spring 54 on the side wall of the connecting block 53, so that the sliding block 55 is separated from the positioning plate 52 on the inner wall of the fixed pipe 51, and the gas is discharged outside the device through the air vent slot 56 on the side wall of the fixed pipe 51, completing the evacuation of the air in the presser 1.
[0036] After the presser 1 is released, the elastic potential energy of the reset spring 2 inside the presser 1 is released, pushing the side wall of the presser 1 to reset and expand the internal volume, forming a negative pressure environment. At this time, the external air pressure is greater than the internal air pressure of the presser 1, the sliding block 55 of the exhaust assembly 5 is reset under the action of the elastic force of the positioning spring 54 and the external air pressure, and re-sticks to the positioning plate 52, blocking the reverse air intake of the air vent slot 56. At the same time, the negative pressure is transmitted to the connection assembly 4 through the spiral guide pipe 72 on the inner wall of the insertion tube 71 of the flow guide assembly 7, the airflow moves along the path of the insertion rod 44, the insertion pipe 43, the corrugated pipe 42 and the first elbow pipe 41, and enters the presser 1 from the inside of the storage barrel 3, forming a negative pressure in the storage barrel 3. In this process, the stomach tube can be continuously connected, and the negative pressure can be adjusted by the patient himself. Since real-time feedback can be achieved, the patient will not feel pain during the process of pressing and sucking, and the negative pressure can be adjusted according to the changes in the patient's body.
[0037] The negative pressure in the storage barrel 3 is conducted to the gastric tube through the gastric tube interface of the side wall, and then acts on the gastrointestinal tract of the patient. Under the action of the pressure difference, the liquid and gas in the gastrointestinal tract flow into the storage barrel 3 along the gastric tube, realizing gastrointestinal decompression. In this process, the telescopic component 73 on the inner wall of the insertion tube 71 adjusts the flow of the gas flow. The gas flow pushes the movable plate 731, drives the outer wall connecting shaft 732 and the telescopic rod 733 to slide along the inner wall of the insertion tube 71, and the second tensile spring 734 outside the telescopic rod 733 is stretched accordingly. The elastic deformation of the second tensile spring 734 can buffer the impact of the gas flow, avoid the sudden change of the flow rate of the gas flow affecting the stability of the negative pressure, and at the same time, the gas flow is auxiliary shunted through the gas outlet slot 74 at the bottom of the insertion tube 71, ensuring that the gas flow is uniformly conducted to the inside of the presser 1, ensuring the stability of the negative pressure, so that the patient's body is stably decompressed.
[0038] Embodiment 2, refer to Figure 1 Figure 4 As a second embodiment of the present application, the difference between this embodiment and the first embodiment is that the excess shrinkage assembly 6 includes a rubber sleeve 61 fixedly connected to the inner wall of the top of the storage barrel 3, a T-shaped sliding tube 62 slidingly connected to the inner wall of the rubber sleeve 61, a rubber sheet 63 fixedly connected to the inner wall of the T-shaped sliding tube 62, a sliding plate 64 fixedly connected to the outer wall of the bottom of the T-shaped sliding tube 62, a damping rod 65 fixedly connected to the outer wall of the top of the sliding plate 64, a first tensile spring 66 sleeved outside the damping rod 65, and the outer wall of the top of the damping rod 65 and the outer wall of the top of the first tensile spring 66 are fixedly connected to the top wall inside the storage barrel 3.
[0039] Specifically, after the liquid and gas in the gastrointestinal tract enter the storage barrel 3, the gas continues to flow to the presser 1 through the connecting assembly 4, thereby maintaining the negative pressure circulation, and the liquid is naturally stored in the storage barrel 3, when the liquid in the storage barrel 3 accumulates to a certain amount, the connecting assembly 4 is disconnected, facilitating subsequent cleaning of the inside of the storage barrel 3, at this time, the excess shrinkage assembly 6 is started to clean the residual liquid in the gastric tube and the storage barrel 3, in the excess shrinkage assembly 6, the rubber sleeve 61 on the inner wall of the top of the storage barrel 3 plays a sealing role to avoid leakage of the negative pressure in the storage barrel 3, when the plug-in pipe 43 is inserted, the T-shaped sliding pipe 62 will be pushed to slide downward along the inner wall of the rubber sleeve 61, in the sliding process, the sliding plate 64 at the bottom of the outer wall of the T-shaped sliding pipe 62 moves downward synchronously, since the damping rod 65 and the top of the first tensile spring 66 are both fixed to the inner top wall of the storage barrel 3, the damping rod 65 and the external first tensile spring 66 at the top of the outer wall are stretched, and the rubber sheet 63 on the inner wall of the T-shaped sliding pipe 62 moves with the T-shaped sliding pipe 62, after the connection of the connecting assembly 4 is disconnected, since the plug-in rod 44 exits the extrusion of the rubber sheet 63 at this time, the rubber sheet 63 is reset due to the elastic force and abuts against each other to form a conical ring to prevent airflow, at this time, the T-shaped sliding pipe 62 rises due to the tension of the first tensile spring 66, and the sliding plate 64 rises in the storage barrel 3, since there is no remaining path for the gas to enter to supplement the air pressure at this time, a negative pressure is generated in the space in the storage barrel 3, at this time, the residual liquid in the gastric tube is sucked out and stored in the storage barrel 3 by the negative pressure generated in the storage barrel 3, so that the gastric tube is cleaner after being disconnected and is not easy to contaminate the bed surface. The remaining structure is the same as that of example 1.
[0040] Example 3, refer to Figure 1 Figure 10 This is the third embodiment of the present application, which is different from the second embodiment: the disengagement assembly 8 includes a bracket 81 fixedly connected to the outer wall of the bottom of the presser 1, a plug-in slot 82 opened in the inner wall of the bracket 81, a limiting plate 83 fixedly connected to the outer wall of the bracket 81, a pushing bar 84 slidingly connected to the inner wall of the limiting plate 83, and a compression spring 85 sleeved on the outside of the pushing bar 84, one end of the compression spring 85 is fixedly connected to the outer wall of the limiting plate 83, and the other end of the compression spring 85 is fixedly connected to the outer wall of the bracket 81.
[0041] Specifically, when the treatment is over or the components need to be replaced, the push bar 84 of the disengagement assembly 8 is pressed to move against the elastic force of the compression spring 85 to the direction of the limiting plate 83, thereby releasing the clamping of the insertion tube 71. At this time, the push bar 84 moves and presses the positioning block 755 of the positioning assembly 75, so that the connecting buckle 754 and the elastic sheet 753 are retracted into the movable cavity 752 and disengaged from the clamping of the support 81. Thus, the insertion tube 71 of the flow guide assembly 7 can be taken out of the insertion slot 82 of the disengagement assembly 8. Subsequently, the insertion tube 43 of the connecting assembly 4 is detached from the storage barrel 3, the presser 1 is separated from the storage barrel 3, and finally the gastric tube of the patient is pulled out, thereby completing the disassembly and subsequent cleaning of the device. The remaining structure is the same as that of Example 2.
[0042] The working principle of the present application is as follows: before use, the device needs to be assembled and positioned: the bottom of the insertion tube 71 of the flow guide assembly 7 is aligned with the insertion slot 82 in the inner wall of the support 81 of the escape assembly 8, when inserted, the positioning component 75 in the inner wall of the insertion tube 71 is activated, the insertion block 751 enters the support 81 with the insertion tube 71, the elastic sheet 753 in the movable cavity 752 is extruded and deformed, the connecting buckle 754 and the positioning block 755 are externally elastic and clamped in the clamping groove in the inner wall of the support 81, preliminarily fixing the insertion tube 71;
