Description

Technical Field

[0001] The present invention relates to the technical field of intestinal exhaust, and in particular to an intestinal negative pressure exhaust auxiliary device. Background Art

[0002] Modern people may need to undergo some surgeries due to illness. Some surgeries may cause patients to have abdominal bloating that cannot be eliminated after the operation. Some diseases may also cause waste gas accumulation in the intestinal cavity, causing abdominal bloating. This requires special equipment to assist in exhaust. Anal tube exhaust is suitable for eliminating intestinal gas and alleviating abdominal bloating.

[0003] When venting with the existing anal tube, it is necessary to first perform a defecation operation, then connect one end of the rubber tube to the glass tube, then lubricate the front end of the anal tube, insert it 15 to 18 cm from the anus, and insert the other end into the bottle below the water surface to observe the venting situation. However, in actual use, since the intestinal function of infants and young children is not yet fully developed, their ability to digest food is weak, and their intestinal venting function is also weak, auxiliary venting is required at this time; since infants and young children cannot cooperate with medical staff to vent, when venting, medical staff need to lift the feet of the child with one hand and insert the cannula into the anal canal of the child with the other hand. Since the anal canal of the child is relatively fragile, if the child moves around when inserting the anal canal, it may cause the medical staff to have difficulty in inserting the cannula into the anal canal of the child, resulting in excessive insertion force and too fast speed, resulting in damage to the tissue in the anal canal of the child during insertion, causing accidental injury to the child. Moreover, when the cannula is inserted into the anal canal of the child, there may be uncleaned feces in the anal canal of the child. When the cannula is inserted, the feces may easily block the exhaust hole of the cannula, resulting in the intestinal gas being unable to be discharged normally. The cannula is blocked and the medical staff needs to pull out the cannula, clean the feces in the cannula, and then reinsert the cannula into the anal canal of the child, which increases the operating procedures for exhausting the child's intestines and reduces the treatment effect. Summary of the invention

[0004] In view of the problem that the prior art has that when inserting the cannula into the anal canal of the child, the child is unable to cooperate with the medical staff, which makes it easy for the medical staff to use too much force, causing the cannula to injure the tissue in the anal canal of the child, and there may be excrement in the anal canal of the child, which can easily block the cannula and affect normal exhaust, an intestinal negative pressure exhaust auxiliary device is proposed.

[0005] The present application provides an intestinal negative pressure exhaust assist device, the purpose of which is that when performing intestinal exhaust on a child, medical staff will not easily cause damage to the tissues in the child's anal canal even if they use too much force, and the cannula is inserted into the child's anal canal, and the cannula is not easily blocked, which will not affect the normal exhaust of the intestine.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1, reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides an intestinal negative pressure exhaust auxiliary device, including a handle 1, a connecting hose 11 installed at one end of the handle 1, and an insertion tube 12 installed at the other end of the handle 1, and also includes an insertion unit installed on the insertion tube 12; the insertion unit includes an insertion component installed on the insertion tube 12, and a dredging component installed in the insertion component, the insertion component includes a structural component 2 installed on the insertion tube 12, a plug-in component 3 installed on the inner side of the structural component 2, a limit component 4 installed on the inner side of the plug-in component 3, and a buffer component 5 installed on one side of the plug-in component 3; the structural component 2 includes a connecting tube 21 fixedly connected to the end of the insertion tube 12 away from the handle 1, the end of the connecting tube 21 away from the insertion tube 12 is fixedly connected to a T-shaped tube 24, the outer side of the connecting tube 21 is slidably connected to a sliding sleeve 22, the outer side of the sliding sleeve 22 is fixedly connected to two symmetrically distributed arc blocks 23, and the end of the T-shaped tube 24 away from the connecting tube 21 is slidably connected to a conical sleeve 25.

[0027] Specifically, when in use, the connecting hose 11 is connected to the negative pressure container, and then the medical staff holds the handle 1 by hand and inserts the front end of the device into the anal canal of the child. Through the insertion component, the front end of the device can smoothly enter the anal canal of the child without causing damage to the tissue in the anal canal of the child. The gas in the insertion tube 12, the handle 1 and the connecting hose 11 is extracted through the negative pressure container, so that the gas in the intestine enters the insertion tube 12, the handle 1 and the connecting hose 11 to exhaust the intestine. Through the dredging component, if the device is blocked after being inserted into the anal canal of the child, it can be dredged to avoid the blockage of the pipeline affecting the exhaust of the intestine. Through the conical sleeve 25, the device is conveniently inserted into the anus of the child. The conical sleeve 25 is inserted into the anus of the child and the two arc blocks 23 are pushed through the anus to make the sliding sleeve 22 slide on the connecting tube 21. With the cooperation of the plug-in assembly 3 and the limit assembly 4, the conical sleeve 25 can slide on the T-tube 24. When the conical sleeve 25 completely enters the anal canal of the child, the conical sleeve 25 can be extended and retracted on the T-tube 24 with the cooperation of the buffer assembly 5. When the front end of the device continues to enter the anal canal of the child, the conical sleeve 25 is driven to continue to move into the anal canal of the child. Since the conical sleeve 25 is extended and retracted on the T-tube 24, the conical sleeve 25 can be buffered when it touches the tissue in the anal canal of the child, so as to avoid the conical sleeve 25 from rigidly contacting the tissue in the anal canal of the child and causing damage to the tissue.

[0028] Reference Figure 5 The plug-in assembly 3 includes two symmetrically distributed plug-in grooves 32 opened in the conical sleeve 25, and the T-shaped tube 24 is respectively provided with vertical cavities 31 at the positions corresponding to the two plug-in grooves 32. The inner sides of the two vertical cavities 31 are slidably connected with plug-in rods 34, and the two plug-in rods 34 are respectively plugged into the inner sides of the two plug-in grooves 32 on the opposite sides. The opposite sides of the two plug-in rods 34 are provided with inclined surfaces, and the two inclined surfaces are limitedly slidably connected with moving rods 33. The two moving rods 33 are both slidably connected to the T-shaped tube 24, and the ends of the two moving rods 33 away from the plug-in rods 34 are respectively fixedly connected to the two arc blocks 23.

[0029] Specifically, at the beginning, the tapered sleeve 25 is limited and cannot slide on the T-shaped tube 24, so that when the device is inserted into the anal canal of the child, the tapered sleeve 25 can smoothly enter the anal canal of the child. When the device is inserted into the anal canal of the child, the two arc blocks 23 will conflict with the outer side of the anal canal of the child, pushing the arc blocks 23 to move, driving the moving rod 33 to move. Since the moving rod 33 and the inclined surface are limited and slidably connected, under the action of the inclined surface, the moving rod 33 slides on the inclined surface, and at the same time drives the plug-in rod 34 to slide into the vertical cavity 31, so that the plug-in rod 34 is separated from the inner side of the plug-in groove 32. At this time, the tapered sleeve 25 and the T-shaped tube 24 are movably connected, that is, when the tapered sleeve 25 is fully inserted into the anal canal of the child, the tapered sleeve 25 and the T-shaped tube 24 are movably connected, which can avoid the tapered sleeve 25 from rigidly contacting the tissue in the anal canal of the child, thereby causing damage to the tissue in the anal canal.

[0030] Reference Figure 5 The limiting assembly 4 includes a T-shaped slide groove 41 provided on the inclined surface, a T-shaped slider 42 is slidably connected to the inner side of the T-shaped slide groove 41 , and the T-shaped slider 42 is fixedly connected to the moving rod 33 .

[0031] Specifically, when the moving rod 33 moves, one end of the moving rod 33 slides on the inclined plane, so that the T-shaped slider 42 slides inside the T-shaped slide groove 41, driving the plug-in rod 34 to slide up and down inside the vertical cavity 31, so that the plug-in rod 34 is plugged in or separated from the plug-in groove 32, and the conical sleeve 25 and the T-shaped tube 24 can be controlled to be fixedly connected or movably connected, thereby protecting the tissues in the anal canal of the child.

[0032] Reference Figure 2 The buffer assembly 5 includes two symmetrically distributed sliding grooves 51 opened on the inner side of the conical sleeve 25, and the inner sides of the two sliding grooves 51 are slidably connected with sliding blocks 53. The two sliding blocks 53 are fixedly connected to the T-shaped tube 24, and a buffer spring 52 is fixedly connected between the sliding block 53 and the inner wall of the sliding groove 51.

[0033] Specifically, when the conical sleeve 25 is not limited, the conical sleeve 25 can slide on the T-tube 24, so that the sliding block 53 slides inside the sliding groove 51, squeezing the buffer spring 52. Under the action of the buffer spring 52, the sliding block 53 is buffered, and the conical sleeve 25 is buffered to prevent the conical sleeve 25 from entering the anal canal of the child and rigidly contacting the tissue in the anal canal, thereby causing damage to the tissue in the anal canal.

[0034] Example 2, reference Figure 2 and Figure 6, is the second embodiment of the present invention, which is different from the first embodiment in that: the dredging component includes a dredging component 6 installed on the inner side of the conical sleeve 25, a first winding component 7 installed on one side of the dredging component 6, a locking component 8 installed on the first winding component 7, and a second winding component 9 installed on one side of the first winding component 7; the dredging component 6 includes two symmetrically distributed grooves 62 opened on the inner side of the conical sleeve 25, a moving plate 65 slidably connected between the two grooves 62, a fixed rod 61 fixedly connected to the inner side of the conical sleeve 25, a moving block 64 slidably sleeved on both ends of the fixed rod 61, a return spring 67 sleeved on both ends of the fixed rod 61, one end of the return spring 67 is fixedly connected to the moving block 64, and the other end of the return spring 67 is fixedly connected to the inner wall of the conical sleeve 25, a transmission rod 66 rotatably connected between the two moving blocks 64 and the moving plate 65, and a dredging rod 63 fixedly connected to the moving plate 65.

[0035] Specifically, the dredging assembly 6 is used to dredge the excrement entering the conical sleeve 25 to prevent the excrement from clogging the conical sleeve 25 and affecting the exhaust of the intestine. The two moving blocks 64 slide relatively on the fixed rod 61, and the reset spring 67 is stretched, so that one end of the transmission rod 66 rotates on the moving block 64, and the other end of the transmission rod 66 rotates on the moving plate 65, so that the moving plate 65 slides between the two grooves 62, driving the dredging rod 63 to move into the conical sleeve 25, and the conical sleeve 25 is blocked. The excrement in the tube 25 is unblocked. After unblocking, the reset spring 67 will be reset, driving the two moving blocks 64 to move back to back on the fixed rod 61, so that the transmission rod 66 rotates between the moving block 64 and the moving plate 65, so that the moving plate 65 slides toward the side of the fixed rod 61 on the inner side of the groove 62, driving the unblocking rod 63 to move toward the inner cavity of the conical sleeve 25, avoiding the unblocking rod 63 from clogging the tube hole of the conical sleeve 25, achieving the effect of unblocking the conical sleeve 25 and avoiding the excrement from clogging the tube hole of the device.

[0036] Reference Figure 3 , Figure 7 and Figure 8 The first winding assembly 7 includes a connecting rope 72 fixedly connected to the two moving blocks 64, a first pull rope 71 fixedly connected between the two connecting ropes 72, two symmetrically distributed fixed blocks 74 slidably connected to the inner side of the insertion tube 12, a connecting shaft 75 rotatably connected to the two fixed blocks 74, and a winding roller 73 fixedly connected between the two connecting shafts 75. One end of the first pull rope 71 away from the connecting rope 72 is wound around the outside of the winding roller 73, and a torsion spring 76 is sleeved on the connecting shaft 75. One end of the torsion spring 76 is fixedly connected to the winding roller 73, and the other end of the torsion spring 76 is fixedly connected to the fixed block 74.

[0037] Specifically, the conical sleeve 25 and the T-shaped tube 24 are movably connected. When the conical sleeve 25 touches the tissue in the anal canal, the conical sleeve 25 is retracted on the T-shaped tube 24. At this time, the dredging component 6 will move to the rear side of the device together with the conical sleeve 25. At this time, it is more troublesome to control the dredging component 6. The dredging function of the dredging component 6 can be realized by the first winding component 7. When the dredging component 6 moves to the rear side of the device together with the conical sleeve 25 in the conical sleeve 25, the first pull rope 71 will be relaxed, and the torsion spring 76 will always be The torsion spring 76 will slowly return to its original state, driving the connecting shaft 75 to rotate, driving the winding roller 73 to rotate, winding the first pull rope 71 around the winding roller 73, and tightening the first pull rope 71 again. At this time, when the first pull rope 71 is pulled, the two connecting ropes 72 will be brought together, driving the two moving blocks 64 to slide on the fixed rod 61, and starting the dredging component 6. Regardless of whether the conical sleeve 25 and the T-shaped tube 24 are movably connected or fixedly connected, the dredging component 6 can be used to dredge the tube hole of the conical sleeve 25.

[0038] Reference Figure 4 and Figure 7-Figure 9 The locking assembly 8 includes two symmetrically distributed fixing grooves 81 opened on the inner side of the insertion tube 12, two fixing blocks 74 are respectively slidably connected to the inner sides of the two fixing grooves 81, a connecting spring 85 fixedly connected between the fixing block 74 and the inner wall of the fixing groove 81, a sliding plate 82 slidably connected to the fixing block 74, a first compression spring 86 fixedly connected to one end of the sliding plate 82, the first compression spring 86 is fixedly connected to the fixing block 74 at one end away from the sliding plate 82, a locking rod 84 fixedly connected to the other end of the sliding plate 82, the locking rod 84 is slidably connected to the fixing block 74, a plurality of locking grooves 83 distributed in a ring array opened on the connecting shaft 75, and the locking rod 84 is plugged into the inner side of one of the locking grooves 83 at one end away from the sliding plate 82.

[0039] Specifically, after the first pull rope 71 is rolled up by the winding roller 73, the fixed block 74 slides in the fixed groove 81, which will cause the winding roller 73 to rotate between the two fixed blocks 74, loosening the tightened first pull rope 71. At this time, the dredging component 6 can no longer dredge, and when the sliding plate 82 is pulled, under the action of the connecting spring 85, the fixed block 74 starts to slide in the fixed groove 81. At this time, the sliding plate 82 will pull the first compression spring 86 to extend, so that the locking rod 84 is plugged into the inner side of one of the locking grooves 83, The connecting shaft 75 is limited, so that when the fixing block 74 slides inside the fixing groove 81, the winding roller 73 will not rotate between the two fixing blocks 74, and will not affect the loosening of the tightened first pull rope 71, so that when the sliding plate 82 is pulled, the locking rod 84 is inserted into one of the locking grooves 83, so that the connecting shaft 75 will not rotate, so that the fixing block 74 slides inside the fixing groove 81, drives the winding roller 73 to move, drives the first pull rope 71 to move, and makes the dredging component 6 dredge the pipe hole of the conical sleeve 25. The rest of the structure is the same as that of Example 1.

[0040] Example 3, reference Figure 4 and Figure 7-Figure 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the second winding assembly 9 includes a second pull rope 97 fixedly connected to the sliding plate 82, two symmetrically distributed connecting grooves 95 opened on the inner side of the handle 1, and a connecting rod 96 slidably connected between the two connecting grooves 95. The second pull rope 97 extends from the sliding plate 82 to the inner side of the connecting groove 95 through the insertion tube 12 and is fixedly connected to the connecting rod 96. An active cavity 92 is opened on the top of the inner side of the handle 1, and a winding drum 93 is rotatably connected to the inner side of the active cavity 92, which is fixedly connected to the inner side of the active cavity 92. The winding rope 94 on the connecting rod 96, the winding rope 94 is wound around the outside of the winding drum 93 at one end away from the connecting rod 96, and is slidably connected to the pressure rod 91 on the top of the handle 1, and the bottom of the pressure rod 91 extends to the inside of the winding drum 93, and is fixedly connected to the pressure plate 911 at the bottom of the pressure rod 91, and a protrusion 910 is fixedly connected to the pressure plate 911, and a spiral groove 99 is opened on the inside of the winding drum 93, and the protrusion 910 is slidably connected to the inner side of the spiral groove 99, and a second compression spring 98 is fixedly connected to the bottom of the pressure plate 911, and the bottom of the second compression spring 98 is rotatably connected to the bottom of the inner side of the winding drum 93.

[0041] Specifically, the pressure rod 91 is pressed, and the pressure plate 911 is driven to slide inside the winding drum 93, so that the protrusion 910 slides inside the spiral groove 99. Under the action of the spiral groove 99, the winding drum 93 is rotated, and the winding rope 94 is wound, and the connecting rod 96 is driven to slide inside the connecting groove 95, and the second pull rope 97 is pulled to move, and the sliding plate 82 is driven to move, and the second compression spring 98 is compressed, and the pressure rod 91 is released. Under the action of the second compression spring 98, the pressure plate 911 moves upward inside the winding drum 93, and the protrusion 910 slides upward inside the spiral groove 99, so that the winding drum 93 rotates and the rotation direction is opposite to the direction of the initial rotation, and the wound winding rope 94 is loosened, so that the connecting rod 96 moves inside the connecting groove 95 toward the second pull rope 97, and the second pull rope 97 is loosened, so that the dredging component 6 dredges the tube hole of the conical sleeve 25. The rest of the structure is the same as that of the embodiment 2.

[0042] Based on Examples 1-3, the working principle of the present invention is as follows: when in use, the medical staff holds the handle 1 with their hands and inserts the front end of the device into the anal canal of the child. At the beginning, the T-tube 24 can drive the conical sleeve 25 to move synchronously, so that the conical sleeve 25 can be smoothly inserted into the anal canal of the child. When the conical sleeve 25 is completely inserted into the anal canal of the child, the two arc blocks 23 will conflict with the outer side of the anal canal of the child, so that the arc blocks 23 move toward the insertion tube 12, driving the moving rod 33 to move, so that the plug-in rod 34 is separated from the inner side of the plug-in groove 32. At this time, the conical sleeve 25 and the T-tube 24 are movably connected, which can avoid the conical sleeve 25 from rigidly contacting the tissue in the anal canal of the child and causing damage to the tissue in the anal canal. When the device is inserted into the anal canal of the child and is blocked by excrement, the pressure rod 91 is pressed to drive the pressure plate 911 to move on the inner side of the winding drum 93. The sliding movement causes the projection 910 to slide inside the spiral groove 99. Under the action of the spiral groove 99, the winding drum 93 rotates, thereby winding the winding rope 94, driving the sliding plate 82 to move, so that the locking rod 84 is inserted into one of the locking grooves 83, so that the connecting shaft 75 does not rotate, and the fixed block 74 slides inside the fixed groove 81, driving the winding roller 73 to move, driving the first pull rope 71 to move, and driving the two connecting ropes 72 to be retracted, driving the two moving blocks 64 to slide on the fixed rod 61, so that one end of the transmission rod 66 rotates on the moving block 64, and the other end of the transmission rod 66 rotates on the moving plate 65, so that the moving plate 65 slides between the two grooves 62, driving the dredging rod 63 to move into the conical sleeve 25, and dredging the excrement entering the conical sleeve 25 to prevent the excrement from clogging the device pipe hole.
