Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and in particular relates to a precise gastrointestinal decompression device for clinical use in children. Background Art

[0002] Gastrointestinal decompression utilizes the principles of negative pressure suction and siphoning to remove accumulated gas and fluid from the gastrointestinal tract through a gastric tube inserted through the mouth or nose. This reduces pressure and distension in patients with gastrointestinal obstruction, prevents further leakage of gastrointestinal contents into the abdominal cavity through the perforation, and facilitates the healing of postoperative anastomoses. Therefore, it has a wide range of applications, and is commonly used for acute gastric dilatation, intestinal obstruction, repair or partial resection of gastrointestinal perforations, and after biliary or pancreatic surgery.

[0003] Traditional gastrointestinal decompression devices have a large capacity and are not suitable for children. Even if there are gastrointestinal decompression devices for children, there is no scale accurate to every milliliter. Since fluid management for critically ill children is relatively strict, it is necessary to record the intake and output of the children every hour to judge changes in their condition. In addition, since children do not have mature minds, they are prone to pulling on the hanging tubes during the process of turning over. In view of this, the present invention is specially proposed.

DETAILED DESCRIPTION

[0031] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0032] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a precision gastrointestinal decompression device for clinical use in children, including a liquid storage tank 1, a sealing cover 3, a gastric tube 5, a negative pressure tube 4, and a base 15. The upper end of the liquid storage tank 1 is installed with a sealing cover 3 through a fixing hoop 2. A negative pressure tube 4 and a gastric tube 5 are respectively installed on the upper end of the sealing cover 3. Scale lines 6 are equidistantly arranged on the front surface of the liquid storage tank 1. A positioning ring 7 is sleeved outside the tank body of the liquid storage tank 1;

[0033] One side of the positioning ring 7 is threadedly connected with a positioning bolt 8. The side end of the positioning bolt 8 contacts the liquid storage tank 1. An optical liquid level sensor 9 is installed on one side inside the positioning ring 7. The other side inside the positioning ring 7 is rotatably connected with a contact wheel 10;

[0034] The front end of the tube body of the gastric tube 5 is sleeved with a limiting sleeve 11. Extension ends 12 that contact the lips of the child are provided at both the upper and lower ends of the limiting sleeve 11. An elastic fixing band 13 is provided between the two extension ends 12. Bonding bands 14 for fixing the gastric tube 5 are provided at the front and rear ends of the limiting sleeve 11;

[0035] At the bottom of the liquid storage tank 1, there is an integrally formed socket 16 that fits the groove of the base 15. The material of the liquid storage tank 1 itself is a transparent material. Considering that the traditional gastrointestinal decompression device has a large capacity and is not suitable for children, even for children's gastrointestinal decompression, there is no scale accurate to each milliliter. Since the fluid management of critically ill children is relatively strict, it is necessary to record the intake and output of the child per hour to judge the change of the condition. And because children do not have a mature mind, there is a drawback that they are prone to pulling the hanging pipeline during turning over. The utility model, through the cooperation of the positioning ring 7, the optical liquid level sensor 9, the scale groove, the processing module, the storage module 21, the wireless module 22 and the speaker, not only monitors the body fluid drained from the child during decompression, but also can set a warning value according to the number of milliliters of body fluid that the current child needs to discharge daily. The setting of the warning value is mainly achieved by loosening the positioning bolt 8, then moving the positioning ring 7 and aligning the optical liquid level sensor 9 with the scale groove at the corresponding milliliter position, and then tightening the positioning bolt 8. At this time, the setting is completed. When the liquid at the drainage exceeds the optical liquid level sensor 9, the detection light emitted by the transmitting end of the optical liquid level sensor 9 will be reflected in the liquid, so that the receiving end of the optical liquid level sensor 9 can obtain a signal. At this time, the data is processed by the processing chip 20 and the data is stored. Subsequently, it will be reminded and informed to the medical staff through the wireless module 22 and the speaker. The wireless module 22 can feedback the data to the hospital's medical system, and the speaker can remind the nearby on-duty nurse. For the situation that the child is prone to cause the gastric tube 5 to fall off, the limiting sleeve 11, the extension end 12, the elastic fixing band 13 and the adhesive tape 14 are used in cooperation to prevent displacement. When the gastric tube 5 is inserted into the designated position, the release paper of the adhesive tape 14 itself is torn off, and then the adhesive tape 14 is used to fix the position of the limiting sleeve 11 and the gastric tube 5 at this time. Finally, the limiting sleeve 11 is worn on the head by using the elastic fixing band 13. At this time, the position of the gastric tube 5 is fixed by the limiting sleeve 11 when the child turns over, and the situation of slipping will not occur.

[0036] Wherein, spring pins 17 are installed on the outer walls of both sides of the base 15. The plugging ends of the two spring pins 17 penetrate into the inside of the groove and are plugged into the concave holes on the side wall of the plugging end. By setting the spring pins 17, it is convenient for the user to disassemble the liquid storage tank 1 from the base 15 for regular cleaning and maintenance.

[0037] Among them, a support frame 18 is opened inside the base 15, and a mainboard 19 is fixedly installed in the middle of the support frame 18, and a processing chip 20, a storage module 21, a wireless module 22, a spare button battery holder 23, a power interface 24 and a plurality of connectors for connecting wires are installed at the front end of the mainboard 19. A silicone block 25 is fixedly installed at the bottom of the base 15, and a magnetic block 26 is provided inside the silicone block 25. A first suction cup 27 is fixedly installed on one side of the base 15, and the optical liquid level sensor 9 is connected to the interface circuit through a wire. When the device is in use, the base 15 can be used to quickly fix the device in the use position. For example, when the use scenario is a children's incubator, the first suction cup 27 will be used to fit the smooth outer wall of the incubator for fixation. When there is ferrous metal in the use scenario, the base 15 can be directly magnetically adsorbed on its surface through the magnetic block 26, which is very convenient.

[0038] Among them, an air pressure sensor 28 is installed on the upper end of the sealing cover 3. The air pressure sensor 28 is connected to the interface circuit through a wire. The air pressure in the liquid storage tank 1 is monitored by setting the air pressure sensor 28.

[0039] Among them, the upper end of the negative pressure tube 4 is connected to the installation tube 30 of the external negative pressure equipment through the connecting tube 29, and a partition is provided in the middle of the connecting tube 29 for the negative pressure tube 4 and the installation tube 30 to contact each other, and a through hole is opened in the middle of the partition, and a waterproof breathable membrane 31 is fixed at the upper and lower ends of the partition. By setting two layers of waterproof breathable membrane 31, it is effectively prevented that the negative pressure will draw out the liquid after the installation tube 30 is docked with the negative pressure equipment in the later stage. The presence of the waterproof breathable membrane 31 will prevent the negative pressure from sucking out the liquid or particulate matter, so that the liquid after drainage will remain in the liquid storage tank 1.

[0040] Among them, the outer part of the gastric tube 5 is covered with an elastic resistance sleeve 32, and one side of the elastic resistance sleeve 32 is fixed to the trigger ring 34 by a connecting rope 33, and the trigger ring 34 is fixedly installed on the detection end of the touch pressure sensor 35. A second suction cup 36 for adsorbing the surface of the incubator is fixed on one side of the touch pressure sensor 35. Considering that the child is mentally immature and may turn over, the gastric tube 5 may slip off. Therefore, even if the gastric tube 5 is fixed by the limiting sleeve 11, it is still necessary to prevent the occurrence of critical situations, such as the tube being wrapped around the child's neck. Therefore, when the present invention is used, the second suction cup 36 is fixed to the outer surface of the incubator, and then the elastic resistance sleeve 32 is adjusted to a suitable position on the outside of the gastric tube 5 for monitoring. When the child turns over, the gastric tube 5 will be driven to move. At this time, the gastric tube 5 will drive the elastic resistance sleeve 32 to move. The movement of the elastic resistance sleeve 32 will move the trigger ring 34 at the detection end of the touch pressure sensor 35 through the connecting rope 33, and an alarm will be issued through the wireless module 22 and the speaker.

[0041] The present utility model is not limited to the above-mentioned embodiments. Anyone should be aware that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, shall fall within the protection scope of the present utility model. The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
