Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a drainage device for the care of critically ill patients. Background Technology

[0002] A drainage device is a medical care device used to drain liquids, gases, or food residues from the body to relieve the burden on a patient, prevent infection, promote wound healing, or perform diagnostic tests. Drainage devices use external containers to collect and remove excess substances from the body by inserting a tube, pump, or other device with a tip inserted into the body or connected to an opening on the body surface.

[0003] A search revealed a patent application with application number CN202410677730.9, which discloses a drainage device comprising: a drainage catheter for draining effusion, the inlet end of which is connected to the patient; an effusion collection device for collecting the effusion, the outlet end of which is connected to the drainage catheter, and a drip rate sensor on the effusion collection device; a housing for mounting the effusion collection device, wherein the effusion collection device is slidably connected to the housing, and the slidable direction of the effusion collection device relative to the housing is parallel to the height direction of the housing; a detection device for detecting the relative position between the effusion collection device and the housing; and a display device on the top of the housing, with both the drip rate sensor and the detection device electrically connected to the display device. This drainage device is easy to use and can help medical personnel objectively and accurately obtain drip rate data and the height data of the effusion collection device on the housing.

[0004] A patent application with application number CN201780035368.3 discloses a body drainage system comprising: a peristaltic pump mechanism (2), a housing (1) for receiving at least a portion of the peristaltic pump mechanism, flexible tube units (3, 6, 7) configured to connect to the patient's access port at the access port end and to the collection unit (8) at the collection unit end, a cover for covering the movable portion of the peristaltic pump mechanism (2), and an adjustment unit configured to adjust the rotational speed of the peristaltic pump mechanism, wherein the flexible tube units (3, 6, 7) are configured to form a loop suitable for unidirectional placement at the peristaltic pump mechanism, such that the peristaltic mechanism can repeatedly compress the pump portion (3) of the flexible tube units (3, 6, 7) to pump in the desired direction.

[0005] A patent application with application number CN201580006175.6 discloses a pleural drainage device for aspirating fluid from a patient's pleural cavity using negative pressure. The device includes a fluid collection container (3) for collecting the aspirated fluid and a drainage tube (4) for connecting the fluid collection container (3) to the patient's pleural cavity (P). The fluid collection container (3) can be connected to a vacuum source (1) to generate negative pressure within it. The device has an adjustable device (5) for reducing the pressure difference during the patient's breathing, wherein the device (5) is adjustable independently of the suction capacity of the vacuum source (1). This device allows for gradual expansion of the lung without risk of damage, thus preparing the lung for the end of drainage.

[0006] Existing drainage devices typically use drainage tubes connected to drainage bags to drain and store fluid accumulated in the patient's body. However, the accumulated fluid in the patient's body tends to be viscous, which can easily cause blockages in the drainage tubes during external drainage. The tubes are then squeezed to clear the blockages, making the process complicated and inconvenient. This can also easily pull on the tubes and cause tearing of the wound.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] like Figures 1 to 3 As shown, a drainage device for critical care patients includes an infusion tube 1; both ends of the infusion tube 1 are connected to a three-way connector 4; an end connector 6 is sleeved at the end of the three-way connector 4 away from the infusion tube 1; a sealing structure is provided on the outer ring of the end connector 6, and the sealing structure is used to seal the end connector 6; one end connector 6 is connected to the patient's body; the other end connector 6 is connected to a drainage bag. Existing drainage devices typically use drainage tubes connected to drainage bags to drain and store fluid accumulated in the patient's body. However, the accumulated fluid in the patient's body tends to be viscous, making it easy to clog the drainage tubes during external drainage. Clearing the blockage by squeezing the tubes is cumbersome and inconvenient, and can easily pull on the tubes, causing wound tearing. Therefore, this embodiment provides a drainage device for the care of critically ill patients. During operation, the end connector 6 at one end of the infusion tube 1 is connected to the patient's drainage port, and the end connector 6 at the other end is connected to the drainage bag; the fluid accumulated in the patient's body is drawn out from the body through the end connector 6, transported along the infusion tube 1, and then enters the drainage bag after passing through the end connector 6 at the other end. Since most of the effusion is viscous, some of it may adhere to the inside of the infusion tube 1, causing blockage and affecting the drainage of the effusion from the patient's body; in this case, it is necessary to clear the blockage inside the infusion tube 1. Close the sealing structure on the end connector 6 near the patient, sealing the end connector 6. Then, use a syringe to draw saline solution and insert it into the angled head of the three-way connector 4 near the patient. Inject the saline solution into the three-way connector 4 near the patient. Because the sealing structure seals the end connector 6 near the patient, the saline solution flows along the infusion tube 1 towards the drainage bag, flushing and cleaning the inside of the infusion tube 1. This effectively cleans the infusion tube 1, improving the ease of operation. At the same time, it avoids pulling on the infusion tube 1 during routine cleaning, thus avoiding pulling on the patient's wound. When it is necessary to clean the fluid accumulated in the drainage bag, close the sealing structure at the end near the drainage bag, seal the end connector 6 away from the patient, and then remove the drainage bag for cleaning. This makes it easier to clean the drainage bag.

[0026] like Figures 1 to 5 As shown, the sealing structure includes a fixed sleeve 7 fixedly connected to the outer ring of the end pipe 6; through grooves are provided on both sides of the fixed sleeve 7; a compression clamp 8 is fixedly connected to both sides of one end of the fixed sleeve 7; the compression clamp 8 is located inside the through groove of the fixed sleeve 7; an annular constraint groove 9 is provided at the other end of the fixed sleeve 7; a limit ring 10 is slidably installed inside the annular constraint groove 9; the compression clamp 8 can be clamped and fixed by the limit ring 10. When it is necessary to block and seal the infusion tube 1 during operation, press the squeezing heads 8 on both sides of the fixing sleeve 7 so that the squeezing heads 8 pass through the through grooves on both sides of the fixing sleeve 7, so that the squeezing heads 8 on both sides clamp the end connector 6 accordingly, blocking and sealing the end connector 6. At this time, the squeezing heads 8 are clamped and fixed by the limiting ring 10, thereby achieving the blocking and sealing of the end connector 6. At the same time, it avoids the loosening and release of the sealing structure, making it easier to clean the infusion tube 1 and the drainage bag.

[0027] like Figures 1 to 5 As shown, the compression head 8 has a U-shaped structure, and the middle part of the side of the compression head 8 near the inside of the fixed sleeve 7 has a trapezoidal protrusion. The bottom of the limiting ring 10 is a fixed circular ring; both sides of the top of the limiting ring 10 are fixed with arc-shaped locking plates. By setting the compression clamp 8 into a U-shaped structure with trapezoidal protrusions, the strength of the compression clamp 8 in clamping and sealing the end pipe 6 is improved; the arc-shaped clamping plates on both sides of the limiting clamping ring 10 can effectively cooperate with the compression clamp 8 for clamping and fixing.

[0028] like Figures 4 to 5 As shown, a spring is sleeved on the outer ring of the limiting ring 10; one end of the spring is fixedly connected to the fixing ring of the limiting ring 10. By setting a spring on the outer ring of the limiting ring 10, the spring is used to fit around the outer ring of the arc-shaped locking plate on both sides of the limiting ring 10 to limit and block the arc-shaped locking plate, thereby preventing the squeezing head 8 from detaching from the inner side of the arc-shaped locking plate of the limiting ring 10. When the sealing structure needs to be loosened, press the spring to compress it, causing it to move from the outside of the arc-shaped retaining plate of the limiting retaining ring 10 toward the fixed ring of the limiting retaining ring 10, releasing the arc-shaped retaining plate of the limiting retaining ring 10. This allows the arc-shaped retaining plate of the limiting retaining ring 10 to bend outward, releasing the squeezing head 8, thereby facilitating the loosening of the sealing structure and clearing the end pipe 6.

[0029] Limiting slots are provided on both sides of the inner side of the annular constraint groove 9; the two limiting slots correspond to the two through slots; the inner ring of the limiting ring 10 is fixedly connected with a limiting block corresponding to the limiting slot; the limiting slots provided inside the annular constraint groove 9 engage with the limiting block of the inner ring of the limiting ring 10, thereby restricting the position of the limiting ring 10, which facilitates the use of the limiting ring 10 with the extrusion head 8.

[0030] like Figures 1 to 4As shown, the outer wall of the beveled head of the tee head 4 is provided with an external thread; a sealing cap 5 is installed on the outer thread of the beveled head of the tee head 4; by installing the sealing cap 5 on the outer thread of the beveled head of the tee head 4, external impurities can be effectively prevented from entering the interior of the tee head 4, thereby effectively reducing the probability of infection for the patient.

[0031] like Figures 1 to 4 As shown, the infusion tube 1 is a flexible tube with connecting sleeves at both ends; the end connector 6 is also a flexible tube with a connecting sleeve at one end; the three-way connector 4 has connecting plugs at both its top and bottom, and the outer ring of the connecting plug has multiple sealing rings; the connecting plugs at both ends of the three-way connector 4 are respectively inserted into the connecting sleeves on the infusion tube 1 and the connecting sleeves on the end connector 6; by making the infusion tube 1 a flexible tube, it is easy to bend the infusion tube 1, which facilitates the patient's movement; by making the end connector 6 a flexible tube, it is easy for the sealing structure to clamp and seal the end connector 6; by providing connecting sleeves at the ends of the infusion tube 1 and the end connector 6, and providing connecting plugs at the end of the three-way connector 4, it is easy to connect the infusion tube 1, the three-way connector 4, and the end connector 6.

[0032] like Figures 1 to 3 As shown, the outer ring of the infusion tube 1 is fitted with multiple pairs of constraint plates 2; the constraint plates 2 are square plate-shaped structures, and a cylindrical structure is fixed to one side of the constraint plates 2; an opening is opened on the cylindrical structure of the constraint plates 2; a circular hole is opened in the overlapping area of ​​two constraint plates 2; a fixing rod 3 is inserted through the inside of the circular hole. During operation, the infusion tube 1 is placed into the cylindrical structure on one side of the constraint plate 2 through the opening, so that the constraint plate 2 is installed on the infusion tube 1. The two opposing constraint plates 2 overlap each other. Then, a fixing rod 3 is passed through the round holes of the two constraint plates 2 to fix the two constraint plates 2 together. The infusion tube 1 is bent by the cooperation of the two constraint plates 2, while avoiding the obstruction of the infusion tube 1 when it is bent. Multiple sets of constraint plates 2 are used to effectively organize the infusion tube 1 into a corrugated shape for storage, thereby avoiding the phenomenon of bending and blockage of the infusion tube 1, which facilitates the drainage treatment of critically ill patients.

[0033] like Figures 1 to 3As shown, the circular hole on the constraint plate 2 has an internal thread; the outer ring of the fixing rod 3 has an external thread; the fixing rod 3 is threadedly engaged with the circular hole on the constraint plate 2; a frustum is fixedly connected to the end of the fixing rod 3, and a cross groove is formed on the frustum; the connection strength between the two constraint plates 2 is improved by the threaded connection between the fixing rod 3 and the circular hole on the constraint plate 2; the cross groove on the frustum of the fixing rod 3 facilitates the installation and removal of the fixing rod 3.

[0034] Working principle: One end connector 6 of the infusion tube 1 is connected to the patient's drainage port, and the other end connector 6 is connected to the drainage bag; the accumulated fluid in the patient's body is drawn out from the body through the end connector 6, transported along the infusion tube 1, and then enters the drainage bag after passing through the other end connector 6. Since most of the effusion is viscous, some of it may adhere to the inside of the infusion tube 1, causing blockage and affecting the drainage of the effusion from the patient's body; in this case, it is necessary to clear the blockage inside the infusion tube 1. Close the sealing structure on the end tube 6 near the patient, press the compression clamps 8 on both sides of the fixing sleeve 7 so that the compression clamps 8 pass through the through grooves on both sides of the fixing sleeve 7, so that the compression clamps 8 on both sides clamp the end tube 6 accordingly, blocking and sealing the end tube 6. At this time, the compression clamps 8 are clamped and fixed by the limiting ring 10. The spring sleeve is on the outer ring of the arc-shaped clamp plate on both sides of the limiting ring 10 to limit and block the arc-shaped clamp plate, preventing the compression clamps 8 from detaching from the inner side of the arc-shaped clamp plate of the limiting ring 10; thus achieving the blocking and sealing of the end tube 6. Next, use a syringe to draw up saline solution and insert it into the angled end of the three-way connector 4 near the patient. Inject the saline solution into the three-way connector 4 near the patient. Because the sealing structure blocks and seals the end connector 6 near the patient, the saline solution flows along the infusion tube 1 towards the drainage bag, using the saline solution to flush and clean the inside of the infusion tube 1. This effectively cleans the infusion tube 1, improves the convenience of operation, and avoids pulling on the infusion tube 1 during routine cleaning, thereby avoiding pulling on the patient's wound. After cleaning, when the sealing structure needs to be loosened, press the spring to compress it and move it from the outside of the arc-shaped retaining plate of the limiting retaining ring 10 toward the fixed ring of the limiting retaining ring 10, releasing the arc-shaped retaining plate of the limiting retaining ring 10. This allows the arc-shaped retaining plate of the limiting retaining ring 10 to bend outward, releasing the squeezing head 8 and clearing the end pipe 6, thereby allowing the accumulated fluid in the patient's body to flow back into the drainage bag. When it is necessary to clean the fluid accumulated in the drainage bag, close the sealing structure at the end near the drainage bag, seal the end connector 6 away from the patient, and then remove the drainage bag for cleaning.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
