Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to an adjustable drainage device for orthopedic nursing. Background Technology

[0002] After orthopedic surgery, drainage devices are often used to drain the wound. Wound drainage devices are commonly used medical instruments in surgery or trauma management. They are mainly used to drain fluid (such as blood, pus, exudate, etc.) from the wound, promote wound healing, and reduce the risk of infection and complications. After orthopedic surgery, they can effectively reduce hematoma compression of nerves and blood vessels.

[0003] Currently, common drainage devices are generally divided into passive drainage devices that rely on gravity or capillary action for natural drainage, and active drainage devices that provide continuous suction through negative pressure. Among them, negative pressure drainage devices are suitable for deep surgeries and cases with large amounts of fluid accumulation. Currently, negative pressure drainage devices usually connect the wound to the drainage tube through a drainage tube. By squeezing the drainage tube, the rebound force of the drainage tube provides the negative pressure needed to aspirate body fluid. This type of negative pressure drainage device has a simple structure and is easy to operate, but it cannot be flexibly adjusted according to the actual situation. Medical staff can only select different sizes of drainage tubes based on their experience. At the same time, the suction force of the drainage tube gradually decreases as body fluid is collected, resulting in an imbalance of suction force and reducing the drainage effect. Furthermore, in postoperative observation, it is often necessary to observe the color of the fluid aspirated from the patient's wound to judge the patient's recovery status or to determine whether infection has occurred. Traditional drainage devices can only judge by observing the color of the fluid collected in the drainage tube and the fluid in the drainage tube, which cannot effectively obtain information about the patient's overall healing process through observation. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an adjustable drainage device for orthopedic care, which can be flexibly adjusted according to the actual situation of the patient and allows for direct observation of the wound healing process.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an adjustable drainage device for orthopedic nursing, comprising an adjustable aspiration chamber, a transfer chamber, a storage chamber, an adjustable negative pressure cylinder, and a recording ring. The transfer chamber is located at the bottom of the adjustable aspiration chamber, the storage chamber is located at the bottom of the transfer chamber, the adjustable negative pressure cylinder is located on the side wall of the adjustable aspiration chamber, the adjustable negative pressure cylinder is connected to the adjustable aspiration chamber, and the recording ring is rotatably located inside the transfer chamber.

[0006] Furthermore, the adjustable liquid extraction chamber includes a storage cylinder, a nut, an insertion port, a drain port, and a threaded outer cylinder. The storage cylinder has an opening at the top, and a threaded section is provided on the inner wall of the top of the storage cylinder. The nut is rotatably located at the top of the storage cylinder and is threadedly engaged with the threaded section. The insertion port is located on the side wall of the storage cylinder and communicates with the storage cylinder. The drain port is located on the bottom wall of the storage cylinder, and the threaded outer cylinder is located at the bottom of the storage cylinder. The drain port connects the storage cylinder and the threaded outer cylinder.

[0007] Furthermore, a one-way valve is provided inside the insertion port. The one-way valve restricts the liquid from flowing into the storage cylinder only from the outside through the insertion port. The one-way valve can be electrically controlled to open and close at a time, thereby controlling the drainage at a time.

[0008] Furthermore, a second one-way valve is provided inside the drain port, which restricts the liquid to flow only from the storage cylinder to the outside through the drain port.

[0009] Furthermore, the adjustable negative pressure cylinder includes a sleeve, a piston, an auxiliary cylinder, a spring, a screw, a screw hole, an electric telescopic rod, and a handle. The sleeve is located on the side wall of the storage cylinder and communicates with the storage cylinder. The piston is slidably engaged within the sleeve, and the auxiliary cylinder is slidably engaged within the sleeve. The auxiliary cylinder is located on the side of the piston away from the storage cylinder, and the end of the auxiliary cylinder near the piston is open. The spring is located within the auxiliary cylinder and connects the piston to the side wall of the auxiliary cylinder. The screw hole is located on the side wall of the auxiliary cylinder away from the piston. The handle is rotatably located at the end of the sleeve away from the storage cylinder. The electric telescopic rod is located on the side of the handle near the storage cylinder. The screw is located at the end of the electric telescopic rod and rotatably engaged within the screw hole, with the screw threaded into the screw hole.

[0010] In the initial state, the auxiliary cylinder is in contact with the piston, and the spring is in a stretched state.

[0011] Furthermore, the transfer chamber includes a transfer cylinder, a threaded inner cylinder, an annular groove, a mainspring, an operating chamber, a bevel gear, and a liquid inlet. The transfer cylinder is located below the threaded outer cylinder, and the threaded inner cylinder is located at the top of the transfer cylinder. The threaded inner cylinder is rotatably located inside the threaded outer cylinder, and the threaded inner cylinder and the threaded outer cylinder are threadedly engaged. The annular groove is formed on the side wall of the transfer cylinder, and the operating chamber is formed inside the transfer cylinder and located below the annular groove. The mainspring is located on the outer wall of the transfer cylinder, and the bevel gear is rotatably located inside the operating chamber. The bevel gear is connected to the output end of the mainspring. The liquid inlet is formed on the inner wall of the annular groove and connects the annular groove with the inner channel of the transfer cylinder.

[0012] Furthermore, the recording ring includes a ring body, a recording chamber, a collection port, and a bevel gear ring. The ring body is rotatably disposed within an annular groove. The recording chamber is circumferentially arranged on the inner side of the ring body. The collection port is located on the side wall of the recording chamber. The bevel gear ring is disposed at the bottom of the ring body and meshes with a bevel gear. The height of the collection port is the same as the height of the liquid inlet.

[0013] The ring is made of a transparent material.

[0014] Furthermore, the storage compartment is connected to the transfer cylinder, and the side wall of the storage compartment is provided with air holes.

[0015] Furthermore, the storage compartment is made of a transparent material.

[0016] The beneficial effects of this invention using the above structure are as follows: This solution provides an adjustable drainage device for orthopedic nursing. By contracting the electric telescopic rod, the piston can be moved away from the storage cylinder, thereby generating negative pressure and drawing body fluid from the wound into the storage cylinder. When adjustment is needed, the nut can be rotated to adjust the space inside the storage cylinder. When the nut is rotated upwards, the space inside the storage cylinder increases. When the electric telescopic rod contracts, the proportion of space expanded by the piston decreases, thus reducing the suction force; conversely, the suction force increases. Simultaneously, rotating the handle drives the screw to rotate, thereby driving the auxiliary cylinder closer to or away from the piston, causing the spring to stretch or compress. Since the auxiliary cylinder is connected to the piston via a spring rather than a rigid connection, when the electric telescopic rod contracts, the piston is affected by the negative pressure. The movement is delayed, the spring is stretched first and then gradually contracts, bringing the piston closer to the screw. Turning the handle can adjust the initial distance between the auxiliary cylinder and the piston, thereby adjusting the initial elastic force. When the auxiliary cylinder moves away from the piston, the initial elastic force increases and the spring contraction speed decreases. Thus, this invention can adjust both the suction force and the suction speed during a single extension and retraction of the electric telescopic rod, making it flexible and applicable to various situations. Furthermore, during the extension of the electric telescopic rod to deliver body fluid into the storage chamber, the body fluid flows through the inlet and enters the recording chamber through the collection port. Simultaneously, the spring can drive the recording ring to rotate through the bevel gear and bevel tooth ring, allowing the recording chamber to collect body fluid at different times. This facilitates medical personnel's observation of changes in wound body fluid and makes it easier to assess the condition of the wound. Attached Figure Description

[0029] like Figures 1-8 As shown, the present invention provides an adjustable drainage device for orthopedic nursing, comprising an adjustable aspiration chamber 1, a transfer chamber 2, a storage chamber 3, an adjustable negative pressure cylinder 4, and a recording ring 5.

The auxiliary cylinder 403 is located on the side of the piston 402 away from the storage cylinder 101, and the side of the auxiliary cylinder 403 closest to the piston 402... The sleeve 401 has an open end, and a spring 404 is located inside the auxiliary cylinder 403. The spring 404 connects the piston 402 and the side wall of the auxiliary cylinder 403. A screw hole 406 is opened on the side wall of the auxiliary cylinder 403 away from the piston 402. A handle 408 is rotatably located at the end of the sleeve 401 away from the storage cylinder 101. An electric telescopic rod 407 is located on the side of the handle 408 close to the storage cylinder 101. A screw 405 is located at the end of the electric telescopic rod 407. The screw 405 is rotatably located inside the screw hole 406, and the screw 405 is threadedly engaged with the screw hole 406.

[0034] In the initial state, the auxiliary cylinder 403 is in contact with the piston 402, and the spring 404 is in a stretched state.

[0035] Furthermore, the transfer chamber 2 includes a transfer cylinder 201, a threaded inner cylinder 202, an annular groove 203, a spring 204, an operating chamber 205, a bevel gear 206, and a liquid inlet 207. The transfer cylinder 201 is located below the threaded outer cylinder 108, and the threaded inner cylinder 202 is located on top of the transfer cylinder 201. The threaded inner cylinder 202 is rotatably located inside the threaded outer cylinder 108, and the threaded inner cylinder 202 is threadedly engaged with the threaded outer cylinder 108. The annular groove 203 is open. Located on the side wall of the transfer cylinder 201, the operating chamber 205 is opened inside the transfer cylinder 201 and is located below the annular groove 203. The spring 204 is located on the outer wall of the transfer cylinder 201. The bevel gear 206 is rotatably located inside the operating chamber 205 and is connected to the output end of the spring 204. The liquid inlet 207 is opened on the inner wall of the annular groove 203 and connects the annular groove 203 with the inner channel of the transfer cylinder 201.

[0036] Furthermore, the recording ring 5 includes a ring body 501, a recording chamber 502, a collection port 503, and a bevel ring 504. The ring body 501 is rotatably disposed in the annular groove 203. The recording chamber 502 is arranged in a circumferential array on the inner side of the ring body 501. The collection port 503 is disposed on the side wall of the recording chamber 502. The bevel ring 504 is disposed at the bottom of the ring body 501 and meshes with the bevel gear 206. The height of the collection port 503 is the same as the height of the liquid inlet 207.

[0037] Among them, the ring 501 is made of transparent material.

[0038] Furthermore, the storage compartment 3 is connected to the transfer cylinder 201, and the side wall of the storage compartment 3 is provided with an air hole 301.

[0039] Furthermore, storage compartment 3 is made of transparent material.

[0040] In practical use, the transfer chamber 2 and storage chamber 3 are first installed at the bottom of the adjustable suction chamber 1 through the threaded inner cylinder 202 and the threaded outer cylinder 108. An external drainage tube is then inserted into the insertion port 103, connecting the invention to the wound. During drainage, the nut 102 is first rotated to adjust the space inside the storage cylinder 101. When the nut 102 rotates upwards, the space inside the storage cylinder 101 increases. When the electric telescopic rod 407 retracts, the proportion of space expanded by the piston 402 decreases, thus reducing the suction force. Conversely, the suction force increases when the electric telescopic rod 407 retracts. The retraction of the electric telescopic rod 407 causes the piston 402 to move away from the storage cylinder 101, thereby generating negative pressure and drawing bodily fluids from the wound into the storage cylinder 101. Simultaneously, the handle 408 can be rotated to adjust the suction speed. The handle 408 drives the screw 405 to rotate, which in turn drives the screw 405 to adjust the auxiliary cylinder 403 closer to or further away from the piston 402 through the screw hole 406, causing the spring 404 to stretch or compress. Since the auxiliary cylinder 403 is connected to the piston 402 via the spring 404 rather than a rigid connection, it is affected by the negative pressure when the electric telescopic rod 407 retracts. The movement of piston 402 will lag behind, and spring 404 will be stretched first and then gradually contracted, bringing piston 402 closer to screw 405. Rotating handle 408 can adjust the initial distance between auxiliary cylinder 403 and piston 402, thereby adjusting the initial elastic force. When auxiliary cylinder 403 moves away from piston 402, the initial elastic force increases, the contraction speed of spring 404 decreases, and the suction speed increases; conversely, the suction speed decreases. Therefore, this invention can adjust both the suction force and the single suction speed during the extension and retraction of the electric telescopic rod 407, providing flexibility. Applicable to various situations, after the piston 402 contacts the end of the screw 405, the electric telescopic rod 407 extends, pushing the piston 402 to send the body fluid into the storage chamber 3. When the body fluid flows through the transfer chamber 2, the body fluid will flow through the inlet 207, and some body fluid will enter the recording chamber 502 through the collection port 503. At the same time, the spring 204 can drive the recording ring 5 to rotate slowly through the bevel gear 206 and the bevel gear ring 504. The recording chamber 502 collects body fluid at different time periods, which makes it easier for medical staff to observe the changes in wound body fluid and to better judge the condition of the wound.
