Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a heart surgery nursing device. BACKGROUND

[0002] Drainage tubes play a key role in postoperative recovery, and are often inserted after heart surgery. The core purpose of inserting a drainage tube is to drain the blood, exudate and other liquids that may accumulate in the body, prevent complications and monitor changes in the patient's condition.

[0003] In the middle and later stages of recovery, patients can gradually try to get out of bed with the help of medical assessment and assistance. When moving, the drainage tube needs to be properly fixed to avoid pulling on the patient's wound. The traditional fixing device is to pass the drainage tube through the clamping block connected by rotation, and then rotate one of the clamping blocks to fix the drainage tube. However, this causes the problem that the bending position of the drainage tube may cause closure, thereby affecting the smooth drainage of the liquid.

[0004] To solve this problem, the prior art reduces the possibility of the bending position of the drainage tube being closed by scraping the side wall of the drainage tube during the bending process. However, there is still a problem that the drainage tube will recover after the side wall of the drainage tube is scraped. SUMMARY

[0005] The present application aims to provide a heart surgery nursing device to shape the drainage tube after bending to ensure smooth drainage of the liquid.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a heart surgery nursing device, comprising a sticking piece, a base, a clamping frame and two shaping mechanisms oppositely arranged on both sides of the base, the base is fixedly connected with the sticking piece, the base is fixedly provided with a base block, the clamping frame is fixedly provided with a pin shaft, the pin shaft is rotatably connected with the base block, the sticking piece, the base and the clamping frame are provided with a circular hole for the drainage tube to pass through;

[0007] Each shaping mechanism comprises a final extrusion unit and a preliminary extrusion floating unit, the final extrusion unit comprises a first gear, a rack and a threaded tube, a connecting tube and a final extrusion frame connected in sequence, the first gear is fixedly connected with the pin shaft, the rack is slidably arranged on the base, the base is fixedly provided with a support, the end of the threaded tube away from the connecting tube is fixedly provided with a limiting rod, the limiting rod is slidably connected with the support, the threaded tube is threadedly connected with a sleeve, the sleeve is fixedly provided with a second gear, and the rack is engaged with the first gear and the second gear.

[0008] The preliminary extrusion floating unit comprises an elastic rope, a connecting strip and a preliminary extrusion floating block, the connecting strip is rotatably arranged in the connecting tube, the elastic rope is connected with one end of the connecting strip after penetrating through the support and the threaded tube, the preliminary extrusion floating block is connected with the other end of the connecting strip, and the preliminary extrusion floating block can be extended out of the final extrusion frame.

[0009] The beneficial effects of this solution are as follows: The drainage tube located outside the patient's body passes through the circular holes on the adhesive patch, base, and frame in sequence. When the patient moves, rotating the frame can fix the drainage tube. During the rotation of the frame, the first gear on the pin shaft drives the rack to move, which in turn drives the second gear and the sleeve to rotate, thereby driving the threaded tube, connecting tube, and final extrusion frame to move towards the drainage tube. During this process, the connecting strip moves with the connecting tube. Due to the tension of the elastic rope, the connecting strip rotates, thereby driving the first extrusion floating block to extend out of the final extrusion frame.

[0010] Since this solution addresses the issue of closure caused by bends in the drainage tube at the end point, during the bending process, the floating block extends from the final compression frame and contacts part of the drainage tube first. This helps prevent the drainage tube from closing in the later stages of bending, before the final compression frame contacts the drainage tube. As the clamping frame continues to rotate, the two final compression frames come together to compress and shape the bend in the drainage tube, thus solving the problem of the drainage tube re-closing and ensuring smooth liquid drainage.

[0011] Furthermore, this solution also addresses the issues of drainage tube blockage and excessively rapid drainage by utilizing the movement of the final squeezing unit in conjunction with the pre-squeezing floating unit. Specifically, during patient movement, pulling the elastic rope causes the pre-squeezing floating block to squeeze the drainage tube, narrowing the flow channel and accelerating the flow rate to prevent fibrous material from clogging the drainage tube. At the same time, excessively rapid drainage may lead to increased negative pressure, resulting in tissue collapse or increased pain. Therefore, pulling the elastic rope and then releasing it can reset the drainage tube to reduce the fluid flow rate. Thus, the pre-squeezing floating unit addresses both the issues of drainage tube blockage and excessively rapid drainage.

[0012] Furthermore, it also includes bending positioning mechanisms disposed on both sides of the base. Each bending positioning mechanism includes a positioning clamp and a positioning block. The positioning clamp and the positioning block are connected. The positioning clamp is located at the circular hole of the base. The positioning block is slidably connected to the base and engages with the inclined surface of the rack.

[0013] Furthermore, the base is provided with a sliding groove, and sliders are fixed on the sides of the positioning block and the rack. The sliders are slidably disposed in the sliding groove, and a tension spring connects the sliders and the base.

[0014] Furthermore, the first gear comes into contact with the base.

[0015] Furthermore, a support block is fixed on the base, and an arc-shaped groove is provided at the upper end of the support block, with the end of the sleeve rotatably positioned within the arc-shaped groove.

[0016] Furthermore, a limiting disc is fixed to the end of the threaded pipe, and the limiting rod is fixedly connected to the limiting disc.

[0017] Furthermore, there are three limit rods, which are evenly distributed circumferentially on the limit plate. Attached Figure Description

The base 2 is fixedly bonded to the adhesive patch 1. Figure 3 , 4 As shown, a base block 4 is welded onto the base 2, and a pin is welded onto the frame 3. The pin is rotatably connected to the base block 4.

[0028] like Figure 3 , 4 As shown in Figure 6, each shaping mechanism includes a final extrusion unit and a pre-extrusion floating unit. The final extrusion unit includes a first gear 5, a rack 6, and a threaded pipe 7, a connecting pipe 8, and a final extrusion frame 9 that are welded and connected in sequence.Figure 4 As shown, the first gear 5 is welded to the pin shaft, and the end face of the first gear 5 is in contact with the end face of the base 2.
