Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intestinal exhaust, in particular to an intestinal negative pressure exhaust auxiliary device. BACKGROUND

[0002] Modern people may need to undergo some surgery due to diseases in life, and some surgeries may cause abdominal distension of patients after surgery, which cannot be discharged. Some diseases also cause the accumulation of waste gas in the intestinal cavity, causing abdominal distension. Therefore, special equipment is needed to assist in exhaust. The anal tube exhaust technique is suitable for removing intestinal cavity gas and reducing abdominal distension.

[0003] In the existing anal tube exhaust, the defecation operation is needed first, then one end of the rubber tube is connected to the glass tube, then the front end of the anal tube is lubricated, and the other end is inserted into the bottle below the water surface. The exhaust condition is observed, but this exhaust method is not suitable for infants and young children in actual use because the intestinal function of infants and young children has not fully developed, and their digestive capacity is weak. The intestinal exhaust function is also weak. At this time, auxiliary exhaust is needed. Since infants and young children cannot cooperate with medical staff to exhaust, the medical staff needs to lift the feet of the child with one hand and insert the tube 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 during insertion, it may cause the medical staff to have difficulty inserting the tube into the anal canal of the child, resulting in excessive force and speed during insertion, which may damage the tissue in the anal canal of the child and cause accidental injury to the child. In addition, since the anal canal of the child may contain undischarged excrement, the excrement may block the exhaust hole of the tube during insertion, preventing the gas in the intestinal tract from being discharged normally. The tube is blocked, and the medical staff needs to remove the tube, clean the excrement in the tube, and then reinsert the tube into the anal canal of the child, increasing the operation process of the intestinal exhaust of the child and reducing the treatment effect. SUMMARY

[0017] The beneficial effects of the present application are as follows:

[0018] 1. The two arc-shaped blocks will contact the outside of the child's anal canal, pushing the arc-shaped blocks to move and driving the moving rod to move. Since the moving rod and the inclined plane are connected by a limiting sliding connection, the moving rod slides on the inclined plane under the action of the inclined plane, and at the same time drives the insertion rod to slide into the vertical cavity, so that the insertion rod separates from the inside of the insertion groove. At this time, the conical sleeve and the T-shaped tube are connected movably, which can avoid the conical sleeve from making hard contact with the tissue inside the child's anal canal and causing damage to the tissue inside the anal canal;

[0019] 2. By pressing the pressure rod, the pressure plate slides inside the winding drum, causing the protrusion to slide inside the spiral groove. Under the action of the spiral groove, the winding drum rotates, thereby winding the winding rope and driving the winding roller to move. This causes the two connecting ropes to gather together, so that one end of the transmission rod rotates on the moving block and the other end rotates on the moving plate. This clears the excrement entering the conical sleeve tube, preventing the excrement from clogging the device's tube hole, allowing the device to smoothly expel gas from the intestines and improving the treatment effect.

[0020] 3. The conical sleeve is movably connected to the T-shaped tube. When the conical sleeve encounters the excrement in the anal canal and contracts on the T-shaped tube, the first pull rope is loosened. Under the action of the torsion spring, the connecting shaft rotates, which in turn drives the winding roller to rotate and wind up the first pull rope, thus tightening the first pull rope again. This allows the conical sleeve to clear the excrement even when it is contracting, improving the flexibility of the device. Attached Figure Description

[0034] Specifically, in use, the connecting hose 11 is connected with the negative pressure container, then the medical staff holds the handle 1 with hand, inserts the front end part of the device into the anal canal of the child, through the insertion part, the front end part of the device can smoothly enter the anal canal of the child, and the tissue in the anal canal of the child is not damaged, the gas in the intestine enters the insertion tube 12, the handle 1 and the connecting hose 11 through the negative pressure container, the gas in the intestine enters the insertion tube 12, the handle 1 and the connecting hose 11, and the intestine is exhausted, through the dredging part, when the device is inserted into the anal canal of the child and is blocked, dredging can be carried out, so that the pipeline is not blocked and the exhaust of the intestine is affected, through the conical sleeve 25, the device is conveniently inserted into the anal canal of the child, the two arc-shaped blocks 23 are pushed through the anus, the sliding sleeve 22 slides on the connecting pipe 21, under the cooperation of the insertion assembly 3 and the limiting assembly 4, the conical sleeve 25 can slide on the T-shaped pipe 24, when the conical sleeve 25 completely enters the anal canal of the child, under the cooperation of the buffer assembly 5, the conical sleeve 25 can be telescopic on the T-shaped pipe 24, when the front end of the device continues to enter the anal canal of the child, the conical sleeve 25 continues to move into the anal canal of the child, because the conical sleeve 25 is telescopic on the T-shaped pipe 24, when the conical sleeve 25 encounters the tissue in the anal canal of the child, buffering can be carried out, so that the conical sleeve 25 does not hard resist the tissue in the anal canal of the child, and the tissue is not damaged.

[0035] With reference to Figure 5 The insertion assembly 3 comprises two symmetrical insertion grooves 32 formed in the conical sleeve 25, the T-shaped pipe 24 is provided with a vertical cavity 31 at a position corresponding to each of the two insertion grooves 32, an insertion rod 34 is slidably connected to the inner side of each of the two vertical cavities 31, the two insertion rods 34 are respectively inserted into the inner sides of the two insertion grooves 32 at opposite sides, each of the two insertion rods 34 is provided with an inclined surface at an opposite side, a moving rod 33 is slidably connected to each of the two inclined surfaces, the two moving rods 33 are slidably connected to the T-shaped pipe 24, and the two moving rods 33 are respectively fixedly connected to the two arc-shaped blocks 23 at one end away from the insertion rods 34.

[0036] Specifically, the conical sleeve 25 is initially positioned and cannot slide on the T-shaped tube 24, so that the device can smoothly enter the anus of the child when inserted into the anus of the child. When the device is inserted into the anus of the child, the two arc-shaped blocks 23 will be in contact with the outside of the anus of the child, pushing the arc-shaped blocks 23 to move, driving the moving rod 33 to move. Since the moving rod 33 is in limited sliding connection with the inclined surface, under the action of the inclined surface, the moving rod 33 slides on the inclined surface, driving the insertion rod 34 to slide into the vertical cavity 31, so that the insertion rod 34 is separated from the inside of the insertion slot 32. At this time, the conical sleeve 25 is in movable connection with the T-shaped tube 24, that is, when the conical sleeve 25 is completely inserted into the anus of the child, the conical sleeve 25 is in movable connection with the T-shaped tube 24, which can avoid the hard contact between the conical sleeve 25 and the tissue in the anus of the child, and cause damage to the tissue in the anus.

[0037] With reference to Figure 5 , the limiting assembly 4 comprises a T-shaped sliding groove 41 formed on the inclined surface, and a T-shaped sliding block 42 slidably connected to the inside of the T-shaped sliding groove 41, and the T-shaped sliding block 42 is fixedly connected with the moving rod 33.

[0038] Specifically, when the moving rod 33 moves, one end of the moving rod 33 slides on the inclined surface, so that the T-shaped sliding block 42 slides on the inside of the T-shaped sliding groove 41, driving the insertion rod 34 to slide up and down in the vertical cavity 31, so that the insertion rod 34 is inserted or separated from the insertion slot 32.

[0040] Specifically, when the conical sleeve 25 is not positioned, the conical sleeve 25 can slide on the T-shaped tube 24, so that the sliding block 53 slides in the sliding groove 51, and the buffer spring 52 is compressed. Under the action of the buffer spring 52, the sliding block 53 is buffered, the conical sleeve 25 is buffered, and the hard contact between the conical sleeve 25 and the tissue in the anus of the child is avoided, and damage to the tissue in the anus is avoided.

[0041] Embodiment 2, with reference to Figure 2 and Figure 6For the second embodiment of the application, which is different from the first embodiment, the unclogging component includes an unclogging assembly 6 mounted inside the tapered sleeve 25, a first winding assembly 7 mounted on one side of the unclogging assembly 6, a locking assembly 8 mounted on the first winding assembly 7, and a second winding assembly 9 mounted on one side of the first winding assembly 7; the unclogging assembly 6 includes two symmetrical grooves 62 formed inside the tapered sleeve 25, a moving plate 65 slidably connected between the two grooves 62, a fixed rod 61 fixedly connected inside the tapered sleeve 25, a moving block 64 slidably sleeved on both ends of the fixed rod 61, a reset spring 67 sleeved on both ends of the fixed rod 61, one end of the reset spring 67 fixedly connected with the moving block 64, the other end of the reset spring 67 fixedly connected with the inner wall of the tapered sleeve 25, a transmission rod 66 rotatably connected between the two moving blocks 64 and the moving plate 65, and an unclogging rod 63 fixedly connected to the moving plate 65.

[0042] Specifically, by the unclogging assembly 6, the excrement entering the tapered sleeve 25 is unclogged, avoiding the excrement from blocking the tapered sleeve 25 and affecting the exhaust of the intestinal tract. The two moving blocks 64 slide on the fixed rod 61, stretching the reset spring 67, 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, causing the moving plate 65 to slide between the two grooves 62 and drive the unclogging rod 63 to move into the tapered sleeve 25, unclogging the excrement entering the tapered sleeve 25. After unclogging, the reset spring 67 resets, driving the two moving blocks 64 to move away from each other on the fixed rod 61, causing the transmission rod 66 to rotate between the moving blocks 64 and the moving plate 65, causing the moving plate 65 to slide inside the groove 62 to one side of the fixed rod 61, driving the unclogging rod 63 to move into the tapered sleeve 25, avoiding the unclogging rod 63 from blocking the tapered sleeve 25, achieving the effect of unclogging the tapered sleeve 25 and avoiding the excrement from blocking the device.

[0043] Referring to 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 pulling rope 71 fixedly connected between the two connecting ropes 72, two fixed blocks 74 symmetrically distributed and slidably connected inside the insertion tube 12, a connecting shaft 75 rotatably connected to the two fixed blocks 74, a winding roller 73 fixedly connected between the two connecting shafts 75, the first pulling rope 71 wound outside the winding roller 73 at the end away from the connecting rope 72, a torsional spring 76 sleeved on the connecting shaft 75, one end of the torsional spring 76 fixedly connected with the winding roller 73, and the other end of the torsional spring 76 fixedly connected with the fixed block 74.

[0044] Specifically, the conical sleeve 25 is movably connected with the T-shaped tube 24, when the conical sleeve 25 contacts the tissue in the anal tube, the conical sleeve 25 is retracted on the T-shaped tube 24, at this time, the dredging assembly 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 assembly 6, the first winding assembly 7 can realize the dredging function of the dredging assembly 6, when the dredging assembly 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, the torsional spring 76 is always in a twisted state, at this time, the torsional spring 76 will slowly recover to the original state, drive the connecting shaft 75 to rotate, drive the winding roller 73 to rotate, wind the first pull rope 71 on the winding roller 73, and re-tighten the first pull rope 71, at this time, pulling the first pull rope 71 will drive the two connecting ropes 72 to be folded, drive the two moving blocks 64 to slide on the fixed rod 61, start the dredging assembly 6, whether the conical sleeve 25 is movably connected with the T-shaped tube 24 or fixedly connected with the T-shaped tube 24, the dredging assembly 6 can be used to dredge the pipe hole of the conical sleeve 25.

[0045] With reference to Figure 4 and Figures 7-9 , the locking assembly 8 comprises two symmetrical fixed grooves 81 arranged in the inside of the insertion tube 12, two fixed blocks 74 respectively in sliding connection with the inside of the two fixed grooves 81, a connecting spring 85 fixedly connected between the fixed block 74 and the inner wall of the fixed groove 81, a sliding plate 82 in sliding connection with the fixed block 74, a first compression spring 86 fixedly connected to one end of the sliding plate 82, the first compression spring 86 being fixedly connected to the fixed block 74 away from the one end of the sliding plate 82, a locking rod 84 fixedly connected to the other end of the sliding plate 82, the locking rod 84 being in sliding connection with the fixed block 74, a plurality of locking grooves 83 arranged in a ring array on the connecting shaft 75, and the locking rod 84 being inserted into the inside of one of the locking grooves 83 away from the one end of the sliding plate 82.

[0046] Specifically, when the first pull rope 71 is wound by the winding roller 73, the fixed block 74 slides in the fixed groove 81, which makes the winding roller 73 rotate between the two fixed blocks 74, and loosens the first pull rope 71. At this time, the dredging assembly 6 can no longer dredge. When the sliding plate 82 is pulled, the fixed block 74 slides in the fixed groove 81 under the action of the connecting spring 85. At this time, the sliding plate 82 pulls the first compression spring 86 to elongate, and the locking rod 84 is inserted into the inner side of one of the locking grooves 83, which limits the connection shaft 75. Thus, when the sliding plate 82 is pulled, the locking rod 84 is inserted into one of the locking grooves 83, which makes the connection shaft 75 not rotate, and the fixed block 74 slides in the fixed groove 81, which drives the winding roller 73 to move, drives the first pull rope 71 to move, and makes the dredging assembly 6 dredge the pipe hole of the conical sleeve 25.
