Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and in particular relates to a gastrointestinal decompression device with pressure monitoring. Background Art

[0002] In clinical practice, negative pressure drainage device, also known as suction bottle, is generally used in wards, and is mainly used for the discharge of sputum, medical drainage, and the discharge of dirty blood and secretions, etc. Negative pressure drainage device uses the principle of vacuum to generate negative pressure in the human body cavity, thereby guiding the liquid in the cavity to play its role of drainage and purification.

[0003] The negative pressure suction device is mainly composed of three important parts: a hose, a liquid collection bottle and a pressure regulator. There are two hose connection ports on the liquid collection bottle, one of which is connected to the working chamber, and the other is connected to the negative pressure terminal. When it is connected to the negative pressure terminal, negative air pressure will be generated in the liquid collection bottle, so that this negative pressure will guide sputum, secretions or dirty blood into the liquid collection bottle through the drainage of another hose. When the existing negative pressure drainer is connected to the hose, the plug at the end of the hose is directly inserted into the connection port on the drainer. During use, the connection between the hose and the negative pressure drainer is easy to detach, causing drainage interruption. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a gastrointestinal decompression device with pressure monitoring, in which the plug connector on the end of the drainage tube is inserted into the connecting port on the negative pressure drainage device body. When the drainage tube is subjected to external force, it cannot be separated from the negative pressure drainage device body.

[0007] A negative pressure drain body, wherein a negative pressure sensor is arranged inside the negative pressure drain body, a display is fixedly connected to the outside of the negative pressure drain body, and the negative pressure sensor is electrically connected to the display;

[0008] The upper end surface of the negative pressure drain body is provided with two connection ports, and a fixing belt is symmetrically fixedly connected to the circumference of one of the connection ports, and a notch is provided on the fixing belt;

[0009] A drainage tube, wherein both ends of the drainage tube are fixedly connected with plug connectors adapted to the connecting port, the circumferential side of the plug connector is symmetrically fixedly connected with a fixing plate, the fixing plate is provided with holes adapted to the slot, the inside of the holes are slidably connected with symmetrically arranged limit pins, and a spring is arranged between the two limit pins.

[0010] The above technical solution, its principle and technical effect:

[0011] Insert the plug connector at one end of the drainage tube into the connecting port, align the notch on the fixing belt with the fixing plate, squeeze the limit pins so that the two limit pins are immersed in the holes, and after the fixing plate passes through the notch, the outer ends of the two plug connectors are moved out of the holes under the elastic force of the spring. The existence of the limit pins prevents the fixing belt from detaching from the fixing plate.

[0012] Furthermore, a deodorizer is provided at the other connection port.

[0020] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0021] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0022] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0023] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0024] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0025] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0026] Beneficial effects of the present disclosure:

[0027] The plug connector on the end of the drainage tube is inserted into the connecting port on the negative pressure drainage device body. When the drainage tube is subjected to external force, it cannot be separated from the negative pressure drainage device body. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] In the description of the present disclosure, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present disclosure.

[0036] According to the concept of this application, Figures 1 to 5 To describe an embodiment of a gastrointestinal decompression device with pressure monitoring. Specifically, the gastrointestinal decompression device is constructed as a split structure, which has components such as a negative pressure drainage device body 1 and a drainage tube 5. Through the cooperation of the fixed belt 3, the fixed plate 7, the limit pin 9 and other structures, the plug connector 6 at one end of the drainage tube 5 is inserted into the connecting port 2, the notch 4 on the fixed belt 3 is aligned with the fixed plate 7, and the limit pin 9 is squeezed so that the two limit pins 9 are immersed in the hole 8, so that after the fixed plate 7 passes through the notch 4, under the elastic force of the spring 10, the outer ends of the two plug connectors 6 are moved out of the hole 8, and the existence of the limit pin 9 makes the fixed belt 3 unable to detach from the fixed plate 7.

[0037] like Figure 1-5 As shown, a gastrointestinal decompression device with pressure monitoring comprises:

[0038] A negative pressure drain body 1, a negative pressure sensor is arranged inside the negative pressure drain body 1, a display 11 is fixedly connected to the outside of the negative pressure drain body 1, and the negative pressure sensor is electrically connected to the display 11;

[0039] The upper end surface of the negative pressure drain body 1 is provided with two connection ports 2, and a fixing belt 3 is symmetrically fixedly connected to the circumference of one of the connection ports 2, and a notch 4 is opened on the fixing belt 3;

[0040] The drainage tube 5 has two ends fixedly connected with plug connectors 6 matched with the connecting port 2, and the surrounding sides of the plug connector 6 are symmetrically fixedly connected with a fixing plate 7, and the fixing plate 7 is provided with holes 8 matched with the slot 4, and the inside of the holes 8 is slidably connected with symmetrically arranged limit pins 9, and a spring 10 is arranged between the two limit pins 9.

[0041] When in use, the plug connector 6 at one end of the drainage tube 5 is inserted into the connecting port 2, the notch 4 on the fixing belt 3 is aligned with the fixing plate 7, and the limit pins 9 are squeezed so that the two limit pins 9 are immersed in the holes 8. After the fixing plate 7 passes through the notch 4, the outer ends of the two plug connectors 6 are moved out of the holes 8 under the elastic force of the spring 10. The existence of the limit pins 9 prevents the fixing belt 3 from detaching from the fixing plate 7.

[0042] It should be noted that, in the natural state, the spring 10 is in a compressed state, so that the outer end of the limit pin 9 is always outside the hole 8, which can prevent the fixing belt 3 from detaching from the fixing plate 7, wherein the limit pin 9 cannot detach from the hole 8 inside the hole 8.

[0043] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and return to their original shape after the external force is removed. It is also called a "spring". It is generally made of spring steel. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc.

[0044] The negative pressure value inside the negative pressure drainage device body 1 is the largest before it is used. During the continuous drainage process, when some gas and liquid in the patient's body enter the negative pressure drainage device body 1, the negative pressure value gradually decreases. When the negative pressure value reaches a certain level, the drainage effect is poor. At this time, the gas in the negative pressure drainage device body 1 needs to be discharged to increase the negative pressure value inside the negative pressure drainage device body 1. At this time, the negative pressure value on the display 11 can be observed to determine whether the gas in the negative pressure drainage device body 1 needs to be discharged.

[0045] In one embodiment of the utility model, a deodorizer 12 is provided at the other connection port 2. The deodorizer 12 is filled with a deodorant (activated carbon, etc.), and when the gas is discharged, the gas odor can be reduced to a certain extent.

[0047] In one embodiment of the utility model, two connection ports 2 are provided with closing plugs 14. When not in use, the connection ports 2 are closed.

[0048] In one embodiment of the utility model, a through hole 15 is provided on the body 1 of the negative pressure drainer, and two clamps 16 are symmetrically arranged at the through hole 15. One end of the two clamps 16 is threadedly connected with a bidirectional screw 17, and the other end is slidably connected with a guide rod 18, and a hidden button 19 is arranged between the two clamps 16. The hidden button 19 includes a cylinder 20, one end of the cylinder 20 is fixedly connected with a first circular plate 21 with a diameter smaller than the through hole 15, and the other end is fixedly connected with a second circular plate 22. The hidden button 19 is set inside the patient's hospital gown, and the first circular plate 21 is aligned with the through hole 15 through the hospital gown and inserted, and the bidirectional screw 17 is rotated so that the two clamps 16 move toward each other to clamp the cylinder 20, so that the body 1 of the negative pressure drainer is hung on the patient's hospital gown.

[0049] In one embodiment of the utility model, the two ends of the bidirectional lead screw 17 and the guide rod 18 are rotatably connected with a support plate 23, and the support plate 23 is fixedly connected to the negative pressure drain body 1 to support the bidirectional lead screw 17 and the guide rod 18.
