Description

Technical Field

[0001] The invention relates to the technical field of abdominal drainage devices, and more specifically to an abdominal drainage device with a reminder function. Background Art

[0002] Under normal conditions, there is a small amount of fluid in the abdominal cavity (usually less than 200 ml), which lubricates intestinal peristalsis. Any pathological condition that causes an increase in the amount of fluid in the abdominal cavity, when it exceeds 200 ml, is called peritoneal effusion. When a large amount of peritoneal effusion affects the patient's breathing or the patient's abdominal distension symptoms are severe and unbearable, drainage of the peritoneal effusion can be used to relieve the symptoms.

[0003] Peritoneal drainage tube is one of the most commonly used and important basic techniques in abdominal surgery. Its purpose is to drain the fluid and gas accumulated in the abdominal cavity. In clinical practice, after the doctor inserts a peritoneal drainage tube, he uses medical tape to stick the drainage tube to the skin. The fixation effect may not be strong enough. For example, pulling the drainage tube may cause the tube to fall off. Once the drainage tube falls off, body fluids or gases may not be effectively discharged, thereby increasing the risk of infection. In addition, the fallen drainage tube itself may also become a channel for bacteria to enter the body. Therefore, it is particularly important to detect the slippage of the tube in time and deal with it in time. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an abdominal drainage device with a reminder function, which is helpful for timely detection of drainage tube detachment.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A peritoneal drainage device with a reminder function comprises a drainage tube and a drainage bottle connected to the drainage tube, the drainage tube is provided with a reminder component, the reminder component comprises a disc, a slip ring and a trigger switch, the inner wall of the disc is provided with a slide groove, the trigger switch is installed in the slide groove, the slip ring can be slidably embedded in the slide groove, the slip ring is sleeved on the drainage tube and fixedly connected thereto; an adhesive plate for bonding it to the patient's skin surface is installed at the bottom of the disc, after the slip ring slides, the slip ring contacts the trigger switch, and the trigger switch is connected to a buzzer. A plurality of side holes are provided on the insertion end of the drainage tube.

[0007] As a further improvement of the above technical solution:

[0008] The disc comprises a left semi-circular disc and a right semi-circular disc, one end of the left semi-circular disc is hinged to one end of the right semi-circular disc, and the other end of the left semi-circular disc is detachably connected to the other end of the right semi-circular disc through a connecting piece.

[0018] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the technical solution of the present invention is further described in detail in a non-limiting manner in conjunction with the accompanying drawings and specific implementation methods.

[0019] Aiming at the drawback that it is not easy to find the drainage tube falling off in time. After careful analysis, the inventor found that the reason for the above technical problems is mainly due to the limitations of patient activities, changes in body position or the characteristics of the tape itself, and the fixing effect may not always be strong enough. Once the patient accidentally pulls the drainage tube, or the tape loses its stickiness due to long-term use, it may cause the drainage tube to fall off accidentally. When the drainage tube falls off, the patient often has no obvious perception. This is because the drainage tube is usually placed in a more concealed position, and the falling process is often slow, so it is difficult for the patient to find it in time. This results in the inability of body fluids or gases to be discharged from the body through the drainage tube in time, thereby accumulating in the abdominal cavity, increasing the risk of infection. At the same time, the detached drainage tube itself may also become a potential bacterial invasion route, further exacerbating the risk of infection. Based on the above analysis, the inventor designed a peritoneal drainage device with a reminder function, which is conducive to the timely detection of drainage tube detachment.

[0020] like Figures 1 to 3 As shown, the abdominal drainage device includes a drainage tube 1 and a drainage bottle 2 connected to the drainage tube 1. The drainage tube 1 is provided with a reminder component 3, which includes a disc 31, a slip ring 32 and a trigger switch. The inner wall of the disc 31 is provided with a slide groove 39, and the trigger switch is installed in the slide groove 39. The slip ring 32 can be slidably embedded in the slide groove 39. The slip ring 32 is sleeved on the drainage tube 1 and fixedly connected thereto; an adhesive plate 34 is installed at the bottom of the disc 31 to bond it to the patient's skin surface. After the slip ring 32 slides, the slip ring 32 contacts the trigger switch, and the trigger switch is connected to a buzzer 35. A plurality of side holes 11 are provided on the insertion end of the drainage tube 1. The trigger switch is preferably a waterproof touch switch GT-TC116X-HXXX-LX, which is not only waterproof, but also can be triggered by a light touch. The buzzer 35 is preferably a patch buzzer MSS050030L40030SAAAA. Waistbands are provided on both sides of the reminding component 3, and the two waistbands are connected by Velcro. The abdominal drainage device is bonded to the skin of the patient near the abdominal cavity by an adhesive plate 34, and is tied to the patient's waist by a waistband to avoid falling.

[0021] The trigger switch is coupled to the buzzer 35, and the trigger switch is coupled to the buzzer 35 through a wire. After the trigger switch is triggered, the buzzer 35 is turned on and sounds an alarm. The current flows from the positive pole of the power supply to the trigger switch, the buzzer 35, and finally flows back to the negative pole of the power supply. When the trigger switch is pressed, the trigger switch is turned on, and the current flows to the buzzer 35, so that the buzzer 35 alarms. Similar to the common light controlled by a switch, the switch is directly connected in series with the light, and the switch is pressed to make the current flow to the light, so that the light is lit. Due to the alarm scheme set in this application, it can be realized by simply connecting the existing electrical components in series using wires. The series circuit belongs to the prior art; so only the connection of the electrical components is written.

[0022] The disc 31 includes a left semi-disc 36 and a right semi-disc 37. One end of the left semi-disc 36 is hinged to one end of the right semi-disc 37, and the other end of the left semi-disc 36 is detachably connected to the other end of the right semi-disc 37 through a connector 4. The connector 4 includes a connecting strip 41 and two bolts 42. Through holes are provided at both ends of the connecting strip 41. The bolts 42 pass through the through holes and are threadedly connected to the disc 31. By unfastening the connecting strip 41, the disc 31 can be opened and removed from the drainage tube 1, so that the disc 31 can be replaced during the drainage process to ensure that the adhesive plate 34 has stickiness. When the buzzer 35 sounds an alarm, the disc 31 is removed and the drainage tube 1 is re-fixed.

[0023] A pressing piece 5 is installed in the disc 31, and the pressing piece 5 includes a pressing ring 51 and a spring 52. The pressing ring 51 is slidably arranged in the slide groove 39. One end of the spring 52 is fixedly connected to the disc 31, and the other end is connected to the pressing ring 51. The pressing ring 51 is placed in front of the slip ring 32. The slip ring 32 is provided with a protrusion 38, and the pressing ring 51 and the spring 52 are both sleeved on the protrusion 38. After the slip ring 32 slides, the protrusion 38 contacts the trigger switch. By utilizing the elastic force of the spring 52, the drainage tube 1 can be fixed more firmly and not easily dislodged. Even if the medical tape fixing the drainage tube 1 is loose, the force of pulling the drainage tube 1 is required to overcome the elastic force of the spring 52, and the drainage tube 1 will slide and alarm. Due to the existence of the pressing piece 5, the drainage tube 1 is still in the abdominal cavity under the action of the spring 52 after the buzzer 35 alarms, and the medical staff does not need to deal with it urgently, and time is reserved for the medical staff to reinforce the drainage tube 1.

[0024] The drainage bottle 2 includes a bottle body 21 and a lid 22. The lid 22 is inserted into the bottle body 21 and is threadedly connected thereto. The lid 22 is provided with a through hole, and the drainage tube 1 is inserted into the through hole. The lid 22 is provided with a tube body 6. One end of the tube body 6 is a water inlet end, and the other end is a drainage end. The water inlet end of the tube body 6 is arranged around the through hole and is fixedly connected to the lid 22. The drainage end of the tube body 6 has an inclined valve plate 61. The valve plate 61 is made of elastic rubber material and the valve plate 61 and the end of the tube body 6 fit together. The valve plate 61 is installed with a contact photoelectric liquid level sensor 62, and the contact photoelectric liquid level sensor 62 is connected to the buzzer 35. The drainage bottle 2 is made of a transparent material.

[0025] The contact photoelectric liquid level sensor 62 is a switch that uses a photoelectric sensor to control the switch. The photoelectric liquid level switch has a light-emitting tube and a light receiver inside. When the liquid on the drainage tube 1 continues to drip onto the contact photoelectric liquid level sensor 62 of the valve plate 61, the liquid submerges the photoelectric switch probe, and part of the light is refracted into the liquid, and the light reflected back to the receiver is reduced. The contact photoelectric liquid level sensor 62 corresponds to the OFF state, and the buzzer 35 does not respond; when no liquid continues to drip onto the contact photoelectric liquid level sensor 62 of the valve plate 61, the photoelectric switch probe is exposed to the air, and all the light emitted by the light-emitting tube is reflected back to the receiver at the interface between the photoelectric switch and the air, and the contact photoelectric liquid level sensor corresponds to the ON state, and the buzzer 35 sounds an alarm.

[0026] After the contact photoelectric liquid level sensor 62 is connected in parallel with the trigger switch, it is connected in series with the buzzer 35. When no liquid continues to drip onto the contact photoelectric liquid level sensor 62 of the valve plate 61, the buzzer 35 can be triggered to alarm; when the protrusion 38 contacts the trigger switch, the buzzer 35 can also be triggered to alarm. Or there are two buzzers 35, one buzzer 35 is connected to the trigger switch, and the other buzzer 35 is connected to the contact photoelectric liquid level sensor 62. Both of these connection methods can realize timely reminder when the drainage tube 1 is disconnected.

[0027] When the drainage liquid in the drainage tube 1 flows into the tube body 6, due to the gravity of the liquid, the valve plate 61 and the tube body 6 that fit together can be stretched open to form a channel, and the liquid can flow smoothly into the bottle body 21. The inclined valve plate 61 uses the inclined surface as a pressure-bearing surface. When the liquid flows back, the liquid exerts pressure on the pressure-bearing surface, so that the valve plate 61 fits more closely to each other, thereby blocking the channel of the tube body 6, preventing the liquid from flowing back, and reducing the risk of infection. At the same time, the inclined valve plate 61 can make the liquid passing through the valve plate 61 flow quickly into the bottle body 21, and it is not easy to form accumulation in the tube body 6. The contact photoelectric liquid level sensor 62 installed on the valve plate 61 can accurately detect whether the drainage tube 1 is still draining. When no liquid continues to drip onto the contact photoelectric liquid level sensor 62 of the valve plate 61, the photoelectric switch probe is exposed to the air, and all the light emitted by the light-emitting tube is reflected back to the receiver at the interface between the photoelectric switch and the air. The contact photoelectric liquid level sensor corresponds to the ON state, and the buzzer 35 sounds an alarm; medical staff needs to check whether the drainage tube 1 is folded or fallen off, and deal with it in time to reduce the risk of infection.

[0028] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the conception of the present invention should be within the protection scope of the present invention.
