Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and specifically refers to a postoperative nursing drainage device for an intensive care unit. Background Art

[0002] Biliary drainage is an important treatment measure in the intensive care unit, especially when dealing with hepatobiliary diseases and their complications. After surgery, in order to reduce the pressure in the bile duct and promote the excretion of bile, bile needs to be drained. The common drainage method is usually to connect the drainage bag through a drainage tube. This method mainly drains the bile through gravitational potential energy. During use, the drainage bag must always be kept below the height of the gallbladder, otherwise it will affect the drainage effect. Severe cases will cause bile reflux, which will increase the risk of infection and affect the patient's recovery. During the use of this method, due to the long drainage tube, the drainage bag cannot be fixed and is inconvenient to wear, which will affect the patient's daily activities.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: the present invention provides a postoperative care drainage device for an intensive care unit. Drainage can be started by connecting the drainage tube to the liquid inlet. The present invention is worn on the patient's torso by a strap. The drainage tube and the storage tube are always kept vertical by the action of gravity, so that bile is gathered at the bottom of the inner tube one. During the drainage process, the electric telescopic rod controls the adjustable piston rod to reciprocate up and down. During the downward sliding of the piston plate two, the bile can be sucked into the outer tube one from the liquid inlet by negative pressure. Compared with the traditional method of drainage only by gravity potential energy, the negative pressure-assisted drainage method has lower requirements on the wearing position of the drainage device, thereby making the wearing more flexible. At the same time, the bile accumulated at the bottom of the outer tube one will gradually enter the inner tube two through the discharge port as the piston plate one moves downward and be stored, and will be isolated from the outer tube one after the piston plate two enters the inner tube two, and will be stored at the piston plate one. After moving down to the reserved groove and separating from the inner cylinder 2, the bile between the piston plate 1 and the piston plate 2 will flow into the outer cylinder 2, so that the bile is stored separately and isolated from the liquid inlet, so as to prevent the bile that has been discharged from from flowing back, which is safer. At the same time, when the bile discharge flow rate is large, the knob can be rotated to control the rotation of the central rod by sliding the telescopic rod, so as to adjust the height of the piston plate 2 through the threaded section, thereby adjusting the single delivery capacity of the adjustable piston rod and the drainage efficiency. When the bile flow rate is huge and accumulates in the drainage cylinder, the electric telescopic rod can be controlled to push the piston plate 1 to the bottom of the extension groove, and the knob can be rotated to move the piston plate 2 to a position higher than the discharge port, so that the bile accumulated in the drainage cylinder can be quickly discharged. At the same time, the present invention also has a replaceable design. The storage cylinder is connected to the drainage cylinder through the fixed groove and the plug buckle, and the plug rod is inserted into the slot, so that the magnetic buckle is connected to the magnetic groove, and it can be replaced when the bile is full, which is more hygienic.

[0030] When in use, first wear the drainage tube 1 at a suitable position below the gallbladder through the strap 303, then connect the storage tube 2 to the bottom of the drainage tube 1 through the fixing groove 112 and the buckle 202, insert the insertion rod 107 into the slot 405, connect the magnetic buckle 108 with the magnetic groove 410, and align the slide groove 109 with the slide groove 206, then connect the drainage tube to the liquid inlet 102 to complete the installation.

When the patient has a large bile flow, the knob 409 can be rotated to control the rotation of the central rod 401 by sliding the telescopic rod 408. The piston plate 2 403 is affected by the buckle 2 407 and the slide groove 109 and cannot rotate. The central rod 401 rotates and adjusts the height of the piston plate 2 403 through the threaded section 404, thereby adjusting the distance between the piston plate 1 402 and the piston plate 2 403, adjusting the single delivery capacity of the adjustable piston rod 4, and thus adjusting the drainage efficiency. When the bile flow is huge and the bile is in the drainage cylinder, the central rod 401 can be adjusted. 1, the electric telescopic rod 106 can be controlled to push the piston plate 1 402 to the bottom of the extension groove 207, and the knob 409 can be turned to move the piston plate 2 403 to a position higher than the discharge port 105. At this time, the drainage tube is connected to the storage tube 2, and the bile can directly pass through the discharge port 105 and the inner tube 205 into the outer tube 201, so that the bile accumulated in the drainage tube 1 can be quickly discharged. At the same time, this method can also be used to replace the storage tube 2. When the storage tube 2 is full, the one-way valve 110 is closed. After the bile in the drainage tube 1 is drained tightly according to the above method, the storage tube 2 and the adjustable piston rod 4 can be removed for replacement.
