Detailed implementation mode

[0031] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0032] Embodiment 1

[0033] An adjustable ventricular drainage tube stent, as Figures 1-7 shown, includes a hollow base 1, a sleeve 2, a sliding rod 3, a first scale line 4, a connecting frame 5, a hook 6, a sliding plate 7, a rotating shaft 8, a fixing sleeve 9, a placement frame 10, an adjusting mechanism 12 and a fixing mechanism 13. The middle of the top of the hollow base 1 is connected to the sleeve 2 by bolts. A sliding rod 3 is slidably arranged in the sleeve 2. Guide grooves are formed on both the front and rear sides of the sliding rod 3. Guide ridges are arranged on both the front and rear sides in the sleeve 2. The guide ridges are located in the guide grooves. The guide ridges and the guide grooves can guide the up and down sliding of the sliding rod 3. The first scale line 4 is evenly spaced on the right side of the sliding rod 3. The top of the sliding rod 3 is connected to the connecting frame 5 by bolts. Four hooks 6 are evenly spaced and connected to the outside of the connecting frame 5. The hooks 6 are used for hanging the infusion bottle. A sliding plate 7 is slidably arranged on the sliding rod 3. The sliding plate 7 can slide up and down on the sliding rod 3. The right side of the sliding plate 7 is rotatably connected to a rotating shaft 8. A fixing sleeve 9 is threadedly arranged at the front end of the rotating shaft 8. A placement frame 10 is connected to the rotating shaft 8. The placement frame 10 is used for placing the drainage bag. An adjusting mechanism 12 is arranged on the sleeve 2. The adjusting mechanism 12 is used for adjusting the height of the drainage tube. A fixing mechanism 13 is arranged on the placement frame 10. The fixing mechanism 13 is used for fixing the drainage bag.

[0034] As Figures 1-6 shown, the adjusting mechanism 12 includes a mounting shell 121, a winding wheel 122, a pulling rope 123, a guide wheel 124, an elastic member 125, a connecting ring 126, a second knob 127 and a convex block 128. The upper left part of the sleeve 2 is connected to the mounting shell 121 by bolts. A winding wheel 122 is rotatably connected to the left part in the mounting shell 121. A pulling rope 123 is wound around the winding wheel 122. A through hole is formed in the upper left part of the top of the mounting shell 121. The winding wheel 122 passes through the through hole. The pulling rope 123 is connected to the top of the sliding plate 7. A guide wheel 124 is rotatably connected to the left part of the connecting frame 5. The pulling rope 123 bypasses the guide wheel 124. The left front part of the front side of the mounting shell 121 is connected to an elastic member 125. The elastic member 125 is a spring. The front end of the elastic member 125 is connected to a connecting ring 126. The inner side of the connecting ring 126 is rotatably connected to the outer side of the winding wheel 122. A second knob 127 is slidably arranged on the front part of the winding wheel 122 through a slide rail. The second knob 127 can slide back and forth on the winding wheel 122. The rear side of the second knob 127 is rotatably connected to the connecting ring 126. Convex blocks 128 are evenly spaced and connected to the rear side of the second knob 127 in the circumferential direction. Slots adapted to the convex blocks 128 are evenly spaced and formed in the left front part of the front side of the mounting shell 121. The convex blocks 128 can be inserted into the slots, so that the winding wheel 122 cannot rotate.

[0035] As Figure 1 and Figure 7 shown, the fixing mechanism 13 includes a screw 131 and a third knob 132. The screw 131 is threadedly provided on the front side of the placement frame 10. The screw 131 is used to fix the drainage bag, and the front end of the screw 131 is connected to the third knob 132.

[0036] As Figure 1 and Figure 11 shown, it further includes casters 16. The front and rear sides of the bottom of the hollow base 1 are symmetrically and rotatably connected to the casters 16 on the left and right.

[0037] The medical staff pushes the sleeve 2 to move the device to the side of the hospital bed. Under the action of the casters 16, it is convenient for the medical staff to move the device. After the device is moved to the side of the hospital bed, the medical staff brakes the casters 16 to fix the device. Then, the medical staff puts the drainage bag into the placement frame 10, and then turns the third knob 132 counterclockwise to tighten the screw 131 and fix the drainage bag. Subsequently, the medical staff loosens the fixing sleeve 9 to release the placement frame 10, and then turns the placement frame 10 to adjust the angle of the drainage bag, which is convenient for the medical staff to observe the drainage bag. After adjusting the angle of the drainage bag, tighten the fixing sleeve 9 to fix the placement frame 10. The medical staff then pulls the second knob 127 forward. The second knob 127 drives the connecting ring 12 and the convex block 128 to move forward. The elastic member 125 is stretched, and the convex block 128 moves out of the card slot. Then, turn the second knob 127 clockwise. The second knob 127 drives the wire winding wheel 122 to rotate clockwise, and the pull rope 123 is released from the wire winding wheel 122. The slide plate 7 moves downward under its own gravity, and the drainage tube moves downward accordingly, lowering the height of the drainage tube. Turn the second knob 127 counterclockwise. The second knob 127 drives the wire winding wheel 122 to rotate counterclockwise. The wire winding wheel 122 winds up the pull rope 123, and the pull rope 123 pulls the slide plate 7 to move upward, and the drainage tube moves upward accordingly, raising the height of the drainage tube. The moving distance of the drainage tube can be known according to the first scale line 4, so that the drainage tube can be accurately adjusted to the appropriate height. After adjusting the height of the drainage tube, the medical staff pushes the second knob 127 backward, driving the convex block 128 to move backward, so that the convex block 128 is stuck into the card slot, making the wire winding wheel 122 unable to rotate, avoiding the deviation of the height of the drainage tube caused by the rotation of the wire winding wheel 122. The elastic member 125 returns to its original state, and then the drainage starts. After the drainage operation is completed, the medical staff turns the third knob 132 clockwise to loosen the screw 131 and release the drainage bag, and then takes out the drainage bag. The medical staff can hang the infusion bottle on the hook 6 to infuse the patient.

[0038] Embodiment 2

[0039] On the basis of Embodiment 1, as Figure 1 andFigure 8 As shown, it further includes an adjustment mechanism 11 for adjusting the height of the hook 6. The adjustment mechanism 11 includes a first lead screw 111, a worm gear 112, a worm 113, and a first knob 114. The first lead screw 111 is rotatably connected inside the sleeve 2. The first lead screw 111 is threadedly connected to the slide rod 3. The lower part of the first lead screw 111 rotatably penetrates through the top of the hollow base 1. The bottom end of the first lead screw 111 is key-connected to the worm gear 112. The worm 113 is rotatably connected inside the hollow base 1. The worm 113 meshes with the worm gear 112. The front part of the worm 113 is connected to the first knob 114. An extension opening is formed in the front side of the top of the hollow base 1. The first knob 114 extends out from the extension opening.

[0040] As Figure 1 , Figure 9 and Figure 10 shown, it further includes a synchronization mechanism 14. The synchronization mechanism 14 includes a first gear 141, a moving frame 142, a second lead screw 143, a connecting shaft 144, a second gear 145, a rack 146, and a pushing component. The front and rear parts of the winding wheel 122 are both connected to the first gear 141. The second lead screw 143 is rotatably connected to the right side of the bottom of the mounting shell 121. The moving frame 142 is threadedly provided on the second lead screw 143. The moving frame 142 is U-shaped. The upper part of the moving frame 142 is rotatably connected to the connecting shaft 144. Rectangular openings are formed in the front and rear sides of the right part of the mounting shell 121. The connecting shaft 144 can slide up and down in the rectangular openings. The middle part of the connecting shaft 144 is key-connected to the second gear 145. The second gear 145 meshes with the first gear 141. The left side of the slide rod 3 is connected to the rack 146. The rack 146 meshes with the second gear 145. A pushing component for pushing the second knob 127 is provided on the moving frame 142.

[0041] As Figure 9 and Figure 10 shown, the pushing component includes a connecting rod 147 and a wedge block 148. The front side of the top of the moving frame 142 is connected to the connecting rod 147. The left end of the connecting rod 147 is connected to the wedge block 148. The wedge block 148 is located behind the second knob 127. The wedge block 148 is used to push the second knob 127 forward. Two sliding grooves are formed in the left part of the front side of the mounting shell 121. The wedge block 148 can slide up and down in the two sliding grooves.

[0042] Initially, the first gear 141 and the second gear 145 are engaged, the wedge block 148 blocks the second knob 127, the convex block 128 moves out of the clamping groove, and the elastic member 125 is in a stretched state. When it is necessary to adjust the height of the drainage tube, the medical staff rotates the second lead screw 143 clockwise. The second lead screw 143 drives the moving frame 142 to move upward. The moving frame 142 drives the second gear 145 to move upward, so that the second gear 145 and the first gear 141 are disengaged. When the medical staff rotates the second knob 127 to adjust the height of the drainage tube, it will not be affected by the second gear 145. The moving frame 142 can also drive the connecting rod 147 to move upward, thereby driving the wedge block 148 to move upward. The wedge block 148 is not in contact with the second knob 127. The second knob 127 moves backward under the action of the elastic member 125, and the convex block 128 is clamped into the clamping groove. If it is necessary to adjust the height of the hook 6, the medical staff rotates the second lead screw 143 counterclockwise. The second lead screw 143 drives the moving frame 142 to move downward. The moving frame 142 drives the second gear 145 to move downward, so that the second gear 145 and the first gear 141 are engaged. The moving frame 142 can also drive the connecting rod 147 to move downward, thereby driving the wedge block 148 to move downward. The wedge block 148 pushes the second knob 127 to move forward, and the convex block 128 moves out of the clamping groove. The elastic member 125 is stretched. Then, rotate the first knob 114 clockwise. The first knob 114 drives the worm 113 to rotate clockwise. The worm 113 drives the worm wheel 112 to rotate clockwise. The worm wheel 112 drives the first lead screw 111 to rotate clockwise. The first lead screw 111 drives the sliding rod 3 to move upward, thereby driving the hook 6 to move upward to adjust the height of the hook 6. The sliding rod 3 can also drive the rack 146 to move upward. The rack 146 drives the second gear 145 to rotate counterclockwise. The second gear 145 drives the first gear 141 to rotate clockwise. The first gear 141 drives the winding wheel 122 to rotate clockwise, and the pull rope 123 is relaxed, so that the drainage tube moves downward. Rotate the first knob 114 counterclockwise. The first knob 114 drives the worm 113 to rotate counterclockwise. The worm 113 drives the worm wheel 112 to rotate counterclockwise. The worm wheel 112 drives the first lead screw 111 to rotate counterclockwise. The first lead screw 111 drives the sliding rod 3 to move downward, thereby driving the hook 6 to move downward to adjust the height of the hook 6. The sliding rod 3 can also drive the rack 146 to move downward. The rack 146 drives the second gear 145 to rotate clockwise. The second gear 145 drives the first gear 141 to rotate counterclockwise. The first gear 141 drives the winding wheel 122 to rotate counterclockwise. The winding wheel 122 winds up the pull rope 123, so that the drainage tube moves upward. In this way, the height of the hook 6 can be adjusted according to the height of the medical staff to adapt to medical staff of different heights, and the drainage tube can always be at the same height when adjusting the height of the hook 6, without the need to readjust the height of the drainage tube, making it more convenient to use.

[0043] Such as Figure 1 AndFigure 11 As shown, it further includes a measuring mechanism 15. The measuring mechanism 15 includes a sliding ring 151, a measuring plate 152 and a second scale line 153. The upper part of the sleeve 2 is provided with the sliding ring 151 in a sliding manner. The front side of the sliding ring 151 is rotatably connected to the measuring plate 152. The upper part on the right side of the sleeve 2 is provided with the second scale line 153 at equal intervals.

[0044] When performing drainage, medical staff can rotate the measuring plate 152 upward to a horizontal state, and then push the sliding ring 151 upward to drive the measuring plate 152 to move upward so that the measuring plate 152 is flush with the puncture point on the patient's head. The measuring plate 152 can be used as the zero point of measurement. According to the first scale line 4 and the second scale line 153, the distance between the drainage tube and the measuring plate 152 can be known, and thus the distance between the drainage tube and the puncture point on the patient's head can be known, which is convenient for medical staff to adjust the height of the drainage tube. Then release the measuring plate 152, and the measuring plate 152 rotates downward to a vertical state under the action of its own gravity. Release the sliding ring 151, and the sliding ring 151 moves downward under the action of its own gravity.

[0045] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
