Description

Technical Field

[0001] The utility model relates to the technical field of drainage tube positioners, in particular to a positioner for a chest drainage tube. Background Art

[0002] A chest drainage tube is a tube used to drain air or fluid from the chest cavity. It mainly refers to a closed chest drainage tube, which is drawn out from the chest cavity and passed into a water-sealed bottle. It is suitable for the treatment of pneumothorax, hemothorax, etc. When the chest drainage tube assists the patient in drainage treatment, a positioner is required to limit and fix the position of the drainage tube to avoid dislocation of the chest drainage tube during use.

[0003] In the "A New Drainage Tube Fixer" with the patent CN219743645U, it includes a shell, a fixer, a reel, a connecting rope and an elastic member; an opening is provided on the shell; one end of the connecting rope is wound on the reel, and the other end of the connecting rope extends from the opening and is connected to a positioner, the positioner includes a positioning block and a first limiting groove, a second limiting groove and a third limiting groove linearly fixed on the positioning block, and the limiting direction of the second limiting groove is opposite to the direction of the slot openings of the other two limiting grooves. The method of using the present utility model is: fix the fixer on any object that can be used for fixing, and then insert the drainage tube into the first limiting groove, the second limiting groove and the third limiting groove in turn, at which time the drainage tube is fixed in an Ω shape. The positioner of the present utility model has the effect of forcing the drainage tube to bend continuously, and uses the friction between the drainage tube and the limiting groove for fixing. The positioning method is simple, easy to operate with one hand, and convenient and fast;

[0004] When the drainage tube fixer is used, the position of the drainage tube is directly limited and fixed by multiple limiting grooves. However, the multiple limiting grooves are semi-open. When the drainage tube is pulled and dragged, it will be dislocated and pulled off. The position of the drainage tube cannot be limited and clamped, which is not convenient for the stable use of the drainage tube positioner in the later stage.

[0005] Therefore, we proposed that a chest drainage tube locator can solve the above problems well. Utility Model Content

[0006] The purpose of the present utility model is to provide a positioner for a chest drainage tube to solve the problem raised in the above-mentioned background technology that when the drainage tube fixer is used in the market, the position of the drainage tube is directly limited and fixed by a plurality of limit grooves, but the plurality of limit grooves are all semi-open, and when the drainage tube is pulled and dragged, dislocation and displacement and pulling and falling off may occur, and the position of the drainage tube cannot be limited and clamped, which is inconvenient for the stable use of the drainage tube positioner in the later stage.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a positioner for a chest drainage tube, comprising a positioner body, a cover plate being mounted on a slotted upper portion of the positioner body, and the cover plate being transparent, so that the drainage tube body clamped and positioned inside the positioner body can be observed through the cover plate, and the drainage tube body is slidably mounted inside the positioner body;

[0008] It also includes: both ends of the locator body are grooved and a pressing rod is slidably installed therethrough, and the two pressing rods are symmetrically arranged about the vertical center line of the locator body. Both ends of the locator body are grooved and a clamping mechanism is arranged therethrough. The two clamping mechanisms can be used to drive the two arc-shaped clamping plates to position and clamp the drainage tube body after it is penetrated through through the meshing action, so as to avoid the drainage tube body from sliding and falling off due to dragging in the later stage.

At the same time, the inner sides of the two arc-shaped clamping plates are clamped and connected with the drainage tube body, and the drainage tube body after penetration can be clamped and positioned by the two arc-shaped clamping plates.

[0011] Preferably, the inner sides of the two arc-shaped splints are fitted with anti-slip pads by screws, and the two anti-slip pads are made of rubber material, and the outer sides of the two anti-slip pads are fitted and connected to the outer wall of the drainage tube body. The two arc-shaped splints can be used to increase the friction between the locator body and the drainage tube body, thereby preventing the drainage tube body from falling off due to dragging in the later stage.

[0012] Preferably, both sides of the bottom of the locator body are slotted through which positioning plates are slidably installed, and the upper parts of the two positioning plates are penetrated by limit rods that are slidably connected, and the limit rods are slotted and installed inside the locator body through screws, and the upper parts of the two positioning plates are both rotatably installed with limit blocks through reset springs, and the two limit blocks are both arc-shaped, and the upper parts of the two limit blocks are slidably engaged with two rows of limit slots, and the two rows of limit slots are equally spaced on both sides of the interior of the locator body. The two limit blocks can be ejected into the two rows of limit slots in turn by the elastic force of the two reset springs themselves, and the two positioning plates can be slidably limited.

The drainage tube body can be extended to the outside of the locator body in the later stage, and then the two arc-shaped clamping plates can be retracted and moved to limit the position of the drainage tube body after the penetration, so as to avoid the drainage tube body from sliding off after later use, thereby improving the overall stability of the locator body;

[0016] (2) Furthermore, by using anti-skid pads installed on the inner sides of the two arc-shaped clamping plates by screws, and then connecting the outer sides of the two anti-skid pads to the outer wall of the drainage tube body, the friction between the two arc-shaped clamping plates and the drainage tube body can be increased by the two anti-skid pads, thereby preventing the drainage tube body from being dislocated due to pulling after clamping;

At this time, the two transmission gears will simultaneously drive the two moving blocks to retract and move through the rack, and then drive the two arc-shaped clamping plates to retract and move, and then the drainage tube body can be pulled out and reset after clamping, and finally the elastic force of the two torsion springs can be used to elastically reset the positions of the two transmission gears after rotation;

[0018] (4) A positioning plate is slidably installed through a slot on both sides of the bottom of the locator body, and a limit rod is installed through a slot inside the locator body. At the same time, positioning plates are slidably installed through both ends of the limit rod. In the later stage, the two positioning plates can be squeezed at the same time to shrink and move, and then the patient's clothes are placed on the inner sides of the two positioning plates. Then, the locator body can be clamped and installed on the patient's clothes, which is more convenient for the stable use of the drainage tube body in the later stage;

[0019] (5) Furthermore, by using slots on the top of the two positioning plates and rotating the limit blocks through the return springs, the two positioning plates can be pulled and retracted and moved at the same time in the later stage. The two return springs can use their own elastic force to pop out the two limit blocks to the two rows of limit slots in turn. At this time, the two squeezed positioning plates can be slid and limited, avoiding the phenomenon of the positioner body shaking and falling off during later use after positioning, thereby improving the stability of the positioner body.

[0027] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0028] This utility provides the following technical solutions:

[0029] In the first embodiment, in order to solve the problem that the existing positioner body 1 is easily pulled off when positioning the drainage tube body 3, the following is disclosed:

[0030] The locator body 1 has a slotted cover plate 2 mounted on its upper portion. The cover plate 2 is transparent, and the drainage tube body 3 held and positioned inside the locator body 1 can be observed through the cover plate 2. The drainage tube body 3 is slidably mounted inside the locator body 1.

[0031] It also includes: both ends of the locator body 1 are grooved and a pressing rod 4 is slidably installed therethrough, and the two pressing rods 4 are symmetrically arranged about the vertical center line of the locator body 1, and both ends of the locator body 1 are grooved and a clamping mechanism is arranged therethrough. The two clamping mechanisms can be used to drive the two arc-shaped clamping plates 7 to position and clamp the drainage tube body 3 after it is penetrated through through the meshing action, so as to avoid the drainage tube body 3 from sliding and falling off due to dragging in the later stage.

[0032] The clamping mechanism includes an arc-shaped splint 7, wherein the two moving blocks 6 are both slidably installed at the two ends of the interior of the locator body 1, and the inner ends of the two moving blocks 6 are installed with arc-shaped splints 7 by screws, and the two arc-shaped splints 7 are both arc-shaped, and the inner sides of the two arc-shaped splints 7 are clamped and connected with the drainage tube body 3. The clamping mechanism also includes a transmission gear 5, wherein the two transmission gears 5 are rotatably installed at the two ends of the interior of the locator body 1, and the front and rear sides of the two transmission gears 5 are respectively engaged with the moving block 6 and the pressing rod 4 through the rack 9. The interiors of the two transmission gears 5 are slotted with torsion springs 10, and the two torsion springs 10 have the same structure, and the outer ends of the two torsion springs 10 are connected to the inner wall of the locator body 1.

[0033] like Figure 1-Figure 3As shown, when the drainage tube body 3 is positioned and clamped, the two pressing rods 4 are pressed to drive the two transmission gears 5 to rotate simultaneously through the two racks 9. At this time, the two transmission gears 5 will drive the arc-shaped splints 7 connected to the inner ends of the two moving blocks 6 to retract and move through the two racks 9. Then the drainage tube body 3 is extended to the outside of the locator body 1. At this time, the two pressing rods 4 are released, and then the two torsion springs 10 will drive the two transmission gears 5 to reverse at the same time through their own elastic force, so that the two retracted arc-shaped splints 7 can be reset. Then, the two arc-shaped splints 7 can be used to retract and clamp the drainage tube body 3 after penetration, so as to avoid the displacement of the drainage tube body 3 due to dragging in the later stage, thereby improving the overall stability of the locator body 1.

[0034] The second embodiment differs from the first embodiment in that two anti-slip pads 8 are used to increase the friction between the positioner body 1 and the drainage tube body 3, thereby preventing the drainage tube body 3 from being dislocated and offset due to dragging in the later stage.

[0035] The inner sides of the arc-shaped splints 7 are fitted with anti-skid pads 8 by screws, and the two anti-skid pads 8 are both made of rubber material, and the outer sides of the two anti-skid pads 8 are fitted and connected to the outer side wall of the drainage tube body 3.

[0036] like Figure 2 As shown, when the two arc-shaped splints 7 clamp and position the drainage tube body 3, the anti-slip pads 8 installed on the inner side of the two arc-shaped splints 7 will increase the friction between the two arc-shaped splints 7 and the drainage tube body 3, and then the drainage tube body 3 can be prevented from being misaligned and offset after positioning and clamping, which makes it more convenient for the stable use of the locator body 1 in the later stage.

[0037] Embodiment 3 is different from embodiment 2 in that the positioner body 1 can be clamped and positioned on the patient's clothes, and discloses:

[0038] Both sides of the bottom of the locator body 1 are slotted and slidably installed with positioning plates 12, and the upper parts of the two positioning plates 12 are penetrated by the limiting rod 11 that is slidably connected, and the limiting rod 11 is slotted and installed inside the locator body 1 by screws, and the upper parts of the two positioning plates 12 are rotatably installed with limiting blocks 13 through return springs 15, and the two limiting blocks 13 are both arc-shaped, and the upper parts of the two limiting blocks 13 are slidably engaged with two rows of limiting grooves 14, and the two rows of limiting grooves 14 are equally spaced on both sides of the interior of the locator body 1, and the interiors of the two limiting blocks 13 are slotted with vortex springs 17, and the inner sides of the two vortex springs 17 are wrapped with rotating rods 16, and the outer ends of the two rotating rods 16 extend through to the outside of the locator body 1.

[0039] like Figures 1-6As shown, when the locator body 1 is positioned and installed, the patient's clothes are shrunk and placed on the inner side of the two positioning plates 12, and then the two positioning plates 12 are pulled at the same time to shrink and move. At this time, the two limit blocks 13 will be ejected into the two rows of limit grooves 14 in turn through the elastic force of the two reset springs 15 themselves, and then the two moved positioning plates 12 can be slid and limited. At this time, the locator body 1 can be positioned and installed to avoid the locator body 1 from falling off due to shaking and dragging. Finally, the rotating rod 16 can be rotated to drive the limit blocks 13 to separate from the limit grooves 14. At this time, the two positioning plates 12 can be shrunk and reset, and then the locator body 1 can be quickly disassembled and separated, thereby improving the practicality of the locator body 1.
