Description

Technical Field

[0001] The invention relates to the technical field of gastrointestinal decompression, in particular to a decompression device for gastrointestinal examination. Background Art

[0002] Gastrointestinal examination refers to various diagnostic examinations of the gastrointestinal tract, which can quickly detect gastrointestinal diseases or abnormalities. Before some gastrointestinal examinations, gastrointestinal decompression may be required to reduce gastric contents and improve the accuracy of the examination. At the same time, after discovering some gastrointestinal diseases, gastrointestinal decompression is often used as an auxiliary treatment method to help the treatment and recovery of the disease. At this time, a gastrointestinal decompression device is needed; The gastrointestinal decompression device is also called the gastrointestinal decompression device, which is usually composed of a gastric tube, a negative pressure drain and a connecting pipe. It mainly uses the principle of negative pressure suction to absorb the gas and liquid accumulated in the gastrointestinal tract, and relieves the gastrointestinal pressure by removing the gas and liquid in the gastrointestinal tract. The gastrointestinal decompression operation process is as follows: first insert a gastric tube from the patient's oral or nasal cavity into the gastrointestinal tract, then connect the outer end of the gastric tube with a syringe, and use the syringe to extract the patient's gastric juice first to ensure that the gastric tube enters the patient's gastrointestinal tract, then remove the syringe from the gastric tube, and insert the outer end of the gastric tube into the negative pressure drain, and then the negative pressure principle of the negative pressure drain can be used to suck out the gas and liquid accumulated in the patient's gastrointestinal tract to complete the gastrointestinal decompression work; In the process of docking the gastric tube with the syringe, medical staff need to move and adjust the outer end of the gastric tube to facilitate docking with the syringe, which may cause discomfort to the patient when moving the outer end of the gastric tube. At the same time, after the syringe extracts the gastric juice, the syringe needs to be pulled out of the gastric tube and the gastric tube is inserted into the negative pressure drain. During this process, the inner wall of the gastric tube will be moistened by the gastric juice, and bacteria or dust may easily adhere to the inner wall, which may easily affect the health of the patient. At the same time, after the syringe is pulled out, the gastric juice remaining in the gastric tube may easily flow out directly along the gastric tube, causing pollution to the ward. For this reason, we propose a decompression device for gastrointestinal examination. Summary of the invention

[0013] Preferably, the main drainage bottle is provided with a plurality of scales, a fixing plate is fixedly connected to one side of the bottom of the main drainage bottle, and a rubber stopper is provided on the outlet of the main drainage bottle.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When testing whether the gastric tube has entered the gastrointestinal tract of the patient, the present invention first pushes the pressure plate on the top of the mounting frame to squeeze and seal the drainage hose by using the pressure plate, and at this time presses the clamp plate to squeeze the auxiliary drainage bottle to discharge the gas in the auxiliary drainage bottle into the main drainage bottle, and then pushes the pressure plate at the bottom of the mounting frame to seal the main drainage bottle by using the pressure plate, and due to the connecting rod, the pressure plate on the top of the mounting frame is separated from the drainage hose, and at this time the auxiliary drainage bottle is in a negative pressure state, and the gas and liquid in the gastrointestinal tract of the patient can be absorbed through the drainage hose, and then the auxiliary drainage bottle is discharged. The liquid condition in the stomach tube can determine whether the stomach tube has entered the patient's gastrointestinal tract. The device can detect whether the stomach tube has entered the patient's gastrointestinal tract without moving the drainage hose and the stomach tube by arranging the auxiliary drainage bottle and the two pressing plates. At the same time, the main drainage bottle and the auxiliary drainage bottle can be operated independently through the cooperation of the two pressing plates, and there is no need to disassemble and reassemble them. This can avoid the problem of bacteria easily adhering to the inner wall of the stomach tube after the syringe is separated from the stomach tube in the traditional operation, and the residual gastric fluid in the stomach tube flowing out, causing health hazards to the patient. In the process of using the auxiliary drainage bottle of the present invention, the position of the push rod can be adjusted by rotating the docking tube, and the push rod can be used to push the docking rod to separate the baffle and the sealing ring. At this time, there is a cavity between the baffle and the sealing ring, and at this time, the auxiliary drainage bottle can be connected with the drainage hose through the cooperation of the cavity and the connecting hole, so that the auxiliary drainage bottle can be used to absorb the gas and liquid in the patient's gastrointestinal tract. At the same time, by adjusting the telescopic degree between the docking tube and the threaded tube, the distance between the baffle and the sealing ring can be adjusted, so as to adjust the negative pressure drainage effect of the auxiliary drainage bottle, and effectively improve the auxiliary function of the device in detecting whether the gastric tube enters the patient's gastrointestinal tract before gastrointestinal decompression. The present invention squeezes the auxiliary drainage bottle by two splints. Since the two splints are in a planar structure, the gas in the auxiliary drainage bottle can be discharged more thoroughly, which is convenient for the subsequent absorption of gas and liquid in the patient's gastrointestinal tract. At the same time, after the gastrointestinal decompression work is completed, when the device is disassembled and recovered, since a certain amount of gastric juice has been absorbed in the auxiliary drainage bottle, the splint is fixed by using a threaded rod and a threaded hole. At this time, when taking the auxiliary drainage bottle, the auxiliary drainage bottle can be taken directly by holding the splint, so as to avoid the problem that the gastric juice inside the auxiliary drainage bottle will be directly discharged from the opening of the auxiliary drainage bottle after being squeezed, causing pollution to the surrounding environment.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-8 The present invention provides a technical solution: a decompression device for gastrointestinal examination, comprising a main drainage bottle 1, wherein an inlet 11 and an outlet 13 are respectively provided on the top of the main drainage bottle 1. The main drainage bottle 1 is the main structure of the gastrointestinal decompression device. After the air inside the main drainage bottle 1 is discharged, it is in a negative pressure state. Through the negative pressure state, the gas and liquid in the gastrointestinal tract of the patient can be sucked out. A drainage hose 12 is fixedly connected to the inlet 11. When in use, the external gastric tube is connected to the drainage hose 12, and then the gas and liquid in the gastrointestinal tract can be sucked into the main drainage bottle 1 through the inlet 11 for temporary storage. A gas A one-way valve is used to discharge excess gas from the main drainage bottle 1, ensuring that there is enough space in the main drainage bottle 1 to store gastric fluid in the gastrointestinal tract. The main drainage bottle 1 is provided with a plurality of scales 14. A fixing plate 15 is fixedly connected to one side of the bottom of the main drainage bottle 1, and a round hole is provided on the fixing plate 15. When using the device, the main drainage bottle 1 is placed on the bed on one side of the patient's head, and then a paper clip is stuck in the round hole, and the other end of the paper clip is fixed on the bed sheet or pillowcase of the bed to fix the main drainage bottle 1. A rubber stopper is provided on the outlet 13 of the main drainage bottle 1.

[0019] Furthermore, when performing gastrointestinal decompression operation on the patient, the drainage hose 12 is connected to the external gastric tube, and then one end of the external gastric tube is inserted into the gastrointestinal tract from the patient's nasal cavity or oral cavity. Then, the negative pressure of the main drainage bottle 1 is removed, and the gas or liquid in the patient's gastrointestinal tract can be sucked into the main drainage bottle 1 through the inlet 11, and the outlet 13 can discharge the gas in the main drainage bottle 1 to ensure that there is enough space in the main drainage bottle 1 to store gastric juice. When performing gastrointestinal decompression operation, the medical staff can know the storage amount of gastric juice in the main drainage bottle 1 in time through the scale 14, so as to decide whether the gastrointestinal decompression work is completed.

[0020] Combined with Figure 1 , Figure 2 and Figure 3As shown, a mounting frame 2 is sleeved on the drainage hose 12, and a docking hose 3 is fixedly connected to the mounting frame 2. The docking hose 3 and the drainage hose 12 are communicated with each other, and one end of the docking hose 3 away from the mounting frame 2 is fixedly connected to a sealing shell 31, and one end of the sealing shell 31 away from the docking hose 3 is fixedly connected to a threaded tube 5, and a docking tube 51 is threadedly connected to the threaded tube 5, and one end of the docking tube 51 away from the threaded tube 5 is rotatably connected to an auxiliary drainage bottle 6. The volume of the auxiliary drainage bottle 6 is smaller than the main drainage bottle 1, and its suction under negative pressure state will be smaller than that of the main drainage bottle 1. Even if the gastric tube enters the gastrointestinal tract of the patient, the suction generated by the auxiliary drainage bottle 6 is It will not cause great discomfort to the patient. The bottom of the auxiliary drainage bottle 6 is fixedly connected with an air cushion 61, and the bottom of the air cushion 61 contacts the top of the main drainage bottle 1. A pressure plate 21 is slidably connected to the inner top wall and the inner bottom wall of one side of the mounting frame 2. A damping pad is arranged between the pressure plate 21 and the mounting frame 2 to ensure that when the pressure plate 21 squeezes the drainage hose 12, it will not be bounced open by the elasticity of the drainage hose 12 itself, resulting in the drainage hose 12 not being well sealed. A limiting rod 22 is rotatably connected inside the mounting frame 2, and a connecting rod 23 is fixedly connected to the limiting rod 22, and both ends of the connecting rod 23 are rotatably connected to the pressure plate 21 on the same side thereof.

[0021] Furthermore, when using the device, it is first necessary to detect whether the gastric tube has entered the patient's gastrointestinal tract. When performing the detection, first push the pressure plate 21 located at the top of the mounting frame 2, and use the pressure plate 21 to seal the drainage hose 12 portion located above the docking hose 3. At this time, the auxiliary drainage bottle 6 can be pressed to discharge the gas in the auxiliary drainage bottle 6 into the main drainage bottle 1. After the gas in the auxiliary drainage bottle 6 is discharged, push the pressure plate 21 at the bottom of the mounting frame 2, and use the pressure plate 21 to seal the drainage hose 12 portion located below the docking hose 3. When pushing the pressure plate 21 at the bottom of the mounting frame 2, the pressure plate 21 can drive the connecting rod 23 to rotate with the limiting rod 22 as the center of the circle during the movement, so that the connecting rod 23 drives the pressure plate 21 located on the top of the mounting frame 2 to move in the opposite direction, so that the pressure plate 21 located on the top of the mounting frame 2 is separated from the drainage hose 12, and at this time the auxiliary drainage bottle 6 can be connected with the drainage hose 12 and the external gastric tube. At this time, due to the negative pressure state in the auxiliary drainage bottle 6, the gas and liquid in the patient's gastrointestinal tract can be first absorbed through the drainage hose 12 and the external gastric tube through the auxiliary drainage bottle 6. When gastric juice enters the auxiliary drainage bottle 6, it means that the gastric tube has successfully entered the patient's gastrointestinal tract, and then the gastrointestinal decompression operation can be performed normally. Since the volume of the auxiliary drainage bottle 6 is much smaller than the main drainage bottle 1, the auxiliary drainage bottle 6 will greatly reduce the discomfort of the patient when detecting whether the gastric tube has entered the patient's gastrointestinal tract.

[0022] Combined with Figure 3 , Figure 4 and Figure 7As shown, a sealing tube 32 is fixedly connected in the sealing shell 31, and a baffle 4 is slidably connected to one end of the sealing tube 32 near the docking hose 3. An installation cavity 34 is opened between the inner wall of the sealing shell 31 and the outer wall of the sealing tube 32, and a plurality of annular evenly distributed fixing springs 35 are fixedly connected between the inner wall of the sealing shell 31 and the baffle 4, and the fixing springs 35 are all located in the installation cavity 34. A sleeve 41 is fixedly connected to one side of the baffle 4 near the sealing tube 32, and the sleeve 41 is sleeved on the sealing tube 32. A rubber pad is provided between the sleeve 41 and the sealing tube 32 for sealing, which can ensure that gastric fluid will not enter the installation cavity 34 through the gap between the sleeve 41 and the sealing tube 32 during the process of entering the sealing tube 32 through the connecting hole 44. The sealing pad 42 is fixedly connected to one side of the baffle 4 near the sealing tube 32, and the sealing tube 32 is fixedly connected to one end of the sealing tube 32 near the docking hose 3. The diameters of the sealing ring 33 and the sealing gasket 42 are the same as the inner diameter of the sealing ring 33. The side of the sealing gasket 42 close to the sealing tube 32 is fixedly connected with a docking rod 43. The baffle 4 is provided with a number of annularly distributed connecting holes 44. A limiting frame 52 is fixedly connected to the docking tube 51. A push rod 53 is rotatably connected to the limiting frame 52. Since the push rod 53 is rotatably connected, it can be avoided that when the push rod 53 contacts the docking rod 43, when the docking tube 51 rotates, the push rod 53 still follows the rotation of the docking tube 51, resulting in greater wear between the push rod 53 and the docking rod 43. The connecting holes 44 are all located between the sleeve 41 and the sealing gasket 42. The end of the docking rod 43 away from the baffle 4 extends into the sealing tube 32, and the end of the push rod 53 away from the limiting frame 52 extends into the sealing tube 32. The end of the push rod 53 contacts the end adjacent to the docking rod 43.

[0023] Furthermore, when the auxiliary drainage bottle 6 is used, the docking tube 51 is rotated to move it toward the threaded tube 5. During this process, the docking tube 51 can drive the push rod 53 to move together. During the movement of the push rod 53, it can push the docking rod 43. At this time, the docking rod 43 can drive the baffle 4 away from the sealing ring 33, and stretch the fixing spring 35 through the baffle 4. Since the baffle 4 is provided with a sleeve 41, when the baffle 4 is away from the sealing tube 32, a cavity is formed between the baffle 4, the sleeve 41 and the sealing tube 32. At this time, the docking hose 3 is connected to the sealing tube 32 through the connecting hole 44, and the auxiliary drainage bottle 6 is also connected to the drainage hose 12. After that, the auxiliary drainage bottle 6 can be used to absorb gastric fluid, and by changing the extension and contraction between the docking tube 51 and the threaded tube 5 The shrinkage length can be controlled to control the distance between the baffle 4 and the sealing ring 33, so as to adjust the size of the channel between the auxiliary drainage bottle 6 and the docking hose 3. When the auxiliary drainage bottle 6 is used up, the docking tube 51 is rotated in the opposite direction to increase the telescopic length between it and the threaded tube 5. At this time, the docking tube 51 will drive the push rod 53 to move together, and the squeezing force on the docking rod 43 disappears, and the fixing spring 35 starts to rebound, driving the baffle 4 to move toward the sealing ring 33. When the baffle 4 is fitted with the sealing ring 33, the connecting hole 44 can be sealed by the sealing ring 33, and the sealing pad 42 will also be stuck in the sealing ring 33, which can further improve the sealing performance of the sealing tube 32, thereby cutting off the connection between the docking hose 3 and the auxiliary drainage bottle 6, so that the liquid and gas in the patient's gastrointestinal tract can enter the main drainage bottle 1 more smoothly.

[0024] Combined with Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, the top and bottom of the auxiliary drainage bottle 6 are sleeved with mounting rings 7, and both sides of the mounting ring 7 are fixedly connected with tracks 71, and a limiting block is set in the middle of the track 71. A clamping plate 72 is slidably connected between the same ends of each track 71, and the opposite side of the clamping plate 72 is a plane structure. Through this plane structure, the clamping plate 72 can squeeze the auxiliary drainage bottle 6 more thoroughly, so that the negative pressure in the auxiliary drainage bottle 6 is higher. The inner walls of the mounting ring 7 on both sides close to the track 71 are fixedly connected to the two sides of the auxiliary drainage bottle 6, and the top and bottom sides of the clamping plate 72 are A slider 74 is fixedly connected, and a limiting spring 73 is fixedly connected between the slider 74 and the limit block in the middle of the track 71 on the same side. Threaded holes 75 are provided on one side of the sliders 74 on both sides of the top of the splint 72 close to the end of the track 71. Threaded rods 8 are threadedly connected to both ends of the track 71 on the top of the auxiliary drainage bottle 6. A knob 81 is fixedly connected to the end of the threaded rod 8 away from the track 71. A plurality of anti-slip grooves are provided on the surface of the knob 81, which can increase the friction between the knob 81 and the fingers of the medical staff, so that the medical staff can better turn the knob 81.

[0025] Furthermore, when squeezing the auxiliary drainage bottle 6, the medical staff can manually close the two splints 72 together and squeeze the limit spring 73 to make it contract. At this time, the two splints 72 cooperate to squeeze the auxiliary drainage bottle 6, so that the air in the auxiliary drainage bottle 6 is discharged more completely, and then the splints 72 are released. At this time, the squeezing force on the splints 72 disappears, and the limit spring 73 begins to rebound, pushing the two splints 72 back to their original positions, and then driving each threaded rod 8 to rotate through the knob 81, so that the threaded rod 8 is screwed into the threaded hole 75 of the slider 74, so as to fix and limit the splint 72. When the gastrointestinal decompression is completed, the auxiliary drainage bottle 6 is disassembled, and the splint 72 can be held by hand to prevent the auxiliary drainage bottle 6 from being squeezed, resulting in the problem of gastric fluid stored therein being sprayed out.

[0026] Working principle: first, place the device on the bed on one side of the patient's head, then fix the fixing plate 15 to the bed sheet with a paper clip, then connect the external gastric tube with the drainage hose 12, and then insert one end of the external gastric tube into the gastrointestinal tract from the patient's nasal cavity or oral cavity. When the operation is completed, rotate the docking tube 51 to move it toward the direction of the threaded tube 5. During this process, the docking tube 51 can drive the push rod 53 to move together. During the movement of the push rod 53, it can push the docking rod 43. At this time, the docking rod 43 can drive the baffle 4 away from the sealing ring 33, and stretch the fixing spring 35 through the baffle 4. Since the baffle 4 is provided with a sleeve 41, when the baffle 4 is away from the sealing tube 32, a cavity will be formed between the baffle 4, the sleeve 41 and the sealing tube 32. At this time, the docking hose 3 will be connected with the sealing tube 32 through the connecting hole 44, and at this time, the auxiliary drainage bottle 6 is also connected with the drainage hose 12. Then, the pressure plate 21 at the top of the mounting frame 2 is pushed, and the drainage hose 12 portion located above the docking hose 3 is sealed by the pressure plate 21. At this time, the medical staff can manually close the two clamps 72 to each other and squeeze the limit spring 73 to shrink it. At this time, the two clamps 72 cooperate to squeeze the auxiliary drainage bottle 6, so that the air in the auxiliary drainage bottle 6 is discharged into the main drainage bottle 1 through the drainage hose 12. After the gas in the auxiliary drainage bottle 6 is discharged, the pressure plate 21 at the bottom of the mounting frame 2 is pushed, and the pressure plate 21 is used to seal the drainage hose 12 portion located above the docking hose 3. The drainage hose 12 portion located below the docking hose 3 is sealed, and when the pressing plate 21 at the bottom of the mounting frame 2 is pushed, the pressing plate 21 can drive the connecting rod 23 to rotate with the limiting rod 22 as the center of the circle during the movement, so that the connecting rod 23 drives the pressing plate 21 at the top of the mounting frame 2 to move in the opposite direction, so that the pressing plate 21 at the top of the mounting frame 2 is separated from the drainage hose 12, and at this time, the auxiliary drainage bottle 6 can be connected with the drainage hose 12 and the external gastric tube, and then the clamp 72 is released, and the squeezing force on the clamp 72 disappears. The limit spring 73 starts to rebound, pushing the two clamps 72 back to their original positions, and then the knob 81 drives each threaded rod 8 to rotate, so that the threaded rod 8 is screwed into the threaded hole 75 of the slider 74, so as to fix the clamp 72. At this time, due to the negative pressure in the auxiliary drainage bottle 6, the auxiliary drainage bottle 6 can first absorb the gas and liquid in the patient's gastrointestinal tract through the drainage hose 12 and the external gastric tube. When gastric juice enters the auxiliary drainage bottle 6, it means that the gastric tube has successfully entered the patient's gastrointestinal tract. When the auxiliary drainage bottle 6 is used up, it will be The butt joint pipe 51 rotates in the opposite direction, so that the telescopic length between it and the threaded pipe 5 becomes larger. At this time, the butt joint pipe 51 will drive the push rod 53 to move together, and at this time, the extrusion force on the butt joint rod 43 disappears, and the fixing spring 35 starts to rebound, driving the baffle plate 4 to move toward the sealing ring 33. When the baffle plate 4 and the sealing ring 33 are in contact, the connecting hole 44 can be sealed by the sealing ring 33, and the sealing gasket 42 will also be stuck in the sealing ring 33, which can further improve the sealing performance of the sealing pipe 32, thereby isolating the connection between the butt joint hose 3 and the auxiliary drainage bottle 6; After that, since the auxiliary drainage bottle 6 and the drainage hose 12 are in a cut-off state, the positions of the two pressing plates 21 are adjusted so that the two pressing plates 21 do not squeeze the drainage hose 12. At this time, the main drainage bottle 1 and the drainage hose 12 are in a connected state. At this time, the negative pressure of the main drainage bottle 1 is removed, and the gas or liquid in the patient's gastrointestinal tract can be sucked into the main drainage bottle 1 through the inlet 11, and the outlet 13 can discharge the gas in the main drainage bottle 1, ensuring that there is enough space in the main drainage bottle 1 to store gastric juice. When performing gastrointestinal decompression operation, the scale 14 can enable medical staff to know the storage amount of gastric juice in the main drainage bottle 1 in time; When the gastrointestinal decompression is completed, the auxiliary drainage bottle 6 is disassembled and the clamp 72 can be held to prevent the auxiliary drainage bottle 6 from being squeezed and the gastric fluid stored therein from being sprayed out. Afterwards, the auxiliary drainage bottle 6, the main drainage bottle 1 and other tools such as the external gastric tube can be recovered.
