Description

Technical Field

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

[0002] Patients who have undergone abdominal surgery or suffer from gastrointestinal diseases often have difficulty healing the surgical site due to fluid or gas accumulation in the abdomen, increasing the risk of infection; or causing discomfort such as abdominal distension. In order to reduce the gastrointestinal burden, a gastrointestinal decompression device is clinically used to drain the fluid or gas in the patient's abdominal cavity. The gastrointestinal decompression device uses the principle of negative pressure suction to suck out the liquid or gas in the gastrointestinal tract, thereby achieving the purpose of reducing gastrointestinal pressure.

[0003] Clinically, the negative pressure drain device and the gastric tube are usually connected by a hose. The hose needs to avoid being compressed, bent, or folded during the placement of the tube in the patient to avoid affecting the decompression effect. However, in actual use, the hose is inevitably twisted and compressed due to the actual protective measures and the daily needs of the patient. At the same time, the hose is usually inserted vertically on the top of the negative pressure drain device, and the negative pressure drain device is usually hung at the bottom of the patient's bed (hanging on the edge of the bed is prone to squeezing). In this way, the connection between the hose and the negative pressure drain device is inevitably bent, and the hose may even bend when the negative pressure drain device is hung. Utility Model Content

[0004] The purpose of the utility model is to provide a decompression device for gastrointestinal care, which can avoid bending and pressure of a hose and improve safety.

[0005] The decompression device for gastrointestinal care comprises a liquid storage bag, a bottom plate is fixed at the bottom of the liquid storage bag, a top plate is fixed at the top of the liquid storage bag, a connecting pipe which is in a "7" shape and communicates with the inside of the liquid storage bag is fixed on the top plate, and a reset component for keeping the liquid storage bag in an expanded state is installed between the bottom plate and the top plate;

[0006] It also includes a hose, one end of which is fixed with a connector connected to the hose, the other end of the connector is inserted into a connecting pipe, a limiting pipe is fixed to the left wall of the connecting pipe for preventing the connecting head from falling off, a protective pipe is sleeved on the hose for preventing the hose from being deformed under pressure, one end of the protective pipe is sleeved with a connecting sleeve that is rotatably matched with the hose, and the connecting sleeve is sleeved on the limiting pipe and is threadedly matched with the hose.

[0007] Furthermore, the reset component is a spring, one end of the spring is fixed to the top of the bottom plate, and the other end is fixed to the bottom of the top plate. There are a plurality of springs distributed in a ring shape on the outside of the liquid storage bag.

[0008] Furthermore, the connector is installed in the limiting tube and an annular protrusion is fixed on one end located in the limiting tube, and an annular groove for clamping the annular protrusion is formed on the inner side wall of the limiting tube.

[0009] Furthermore, the protective tube is a steel wire hose.

[0010] Furthermore, the liquid storage bag is made of transparent PVC material.

[0011] Furthermore, the side wall of the liquid storage bag is provided with scale lines.

[0012] Furthermore, it also includes a limiting plate in an annular structure, the limiting plate is made of the same material as the liquid storage bag, the top plate is fixed in the upper end of the limiting plate, and the bottom plate is fixed in the lower end of the limiting plate.

[0016] Furthermore, the hook is spherically hinged on the top of the connecting pipe.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model discharges the air in the liquid storage bag from the connecting tube by pressing the top plate downwards, and returns the compressed liquid storage bag to the initial expanded state under the action of the resetting component. Since the liquid storage bag is close to vacuum at this time, suction is generated, forming a negative pressure suction effect. The protective tube with certain hardness and toughness can prevent the hose from being blocked when under pressure, and can also prevent the hose from being bent during the daily activities of the patient, thereby ensuring the smooth flow of the hose and improving the safety of drainage. At the same time, since the connecting tube is in a "7"-shaped structure, the hose is inserted horizontally. At this time, the liquid storage bag is hung under the bed, and the hose will not be bent.

DETAILED DESCRIPTION

[0022] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0023] Example 1

[0024] The decompression device for gastrointestinal care described in this embodiment comprises a liquid storage bag 4, a bottom plate 1 is fixed to the bottom of the liquid storage bag 4, a top plate 5 is fixed to the top of the liquid storage bag 4, a connecting pipe 6 which is in a "7" shape and communicates with the inside of the liquid storage bag 4 is fixed to the top plate 5, and the air in the liquid storage bag 4 is discharged from the connecting pipe 6 by pressing down the top plate 5, wherein the liquid storage bag 4 is made of transparent PVC material, so that it is convenient to observe the color of the drainage in the liquid storage bag 4, and the side wall of the liquid storage bag 4 is provided with scale lines, so that medical personnel can record and grasp the overall situation of drainage at any time;

[0025] refer to Figure 1 A spring 3 is installed between the bottom plate 1 and the top plate 5, one end of the spring 3 is fixed to the top of the bottom plate 1, and the other end is fixed to the bottom of the top plate 5. There are several springs 3 and they are distributed in a ring shape on the outside of the liquid storage bag 4 (the several springs 3 in this end content constitute the reset component for keeping the liquid storage bag 4 in the expanded state as a whole. In actual application, there can also be only one spring 3 and it is sleeved on the outside of the liquid storage bag 4); in this embodiment, the bottom plate 1 and the top plate 5 are driven away from each other by the elastic force of the spring 3, so that the compressed liquid storage bag 4 returns to the initial expanded state. Since the inside of the liquid storage bag 4 is close to vacuum at this time, suction is generated at the pipe mouth of the connecting pipe 6, forming a negative pressure suction effect;

[0026] The hose 10 also includes a hose 10, on which a connector 7 is fixed at one end, and the other end of the connector 7 is inserted into the connecting tube 6. By connecting one end of the hose 10 with the connecting tube 6 and the other end with the stomach tube, the connecting tube 6 and the stomach tube are connected, and the accumulated fluid and gas in the abdominal cavity of the patient are drained under the negative pressure suction of the liquid storage bag 4, so as to achieve the purpose of reducing the pressure in the gastrointestinal tract. At the same time, since the connecting tube 6 is in a "7"-shaped structure, the hose 10 is inserted horizontally. At this time, the liquid storage bag 4 is hung at the bottom of the bed, and the hose 10 will not be bent.

[0027] like Figure 1As shown, the connector 7 is a conical connector, so that it is more convenient for medical personnel to connect the hose 10 to the connecting tube 6. In actual application, both ends of the hose 10 are connected with connectors 7, and the end connected to the stomach tube is also covered with a flow regulator, such as a regulator on an infusion tube for adjusting the flow rate, so as to close the liquid storage bag 4, so as to maintain the vacuum state of the liquid storage bag 4 during installation, and prevent the accumulated fluid from flowing out after use;

[0028] A limiting tube 11 is fixed to the left side wall of the connecting tube 6 to prevent the connecting head 7 from falling off. Figure 1 and Figure 2 As shown, the connector 7 is installed in the limiting tube 11 and an annular protrusion 12 is fixed on one end located in the limiting tube 11. An annular groove for clamping the annular protrusion 12 is provided on the inner wall of the limiting tube 11. The connector 7 is automatically clamped after being inserted into the connecting tube 6 through the annular protrusion 12 and the annular groove, thereby preventing the hose 10 from being separated from the connecting tube 6 due to external force. In actual application, a sealing gasket can also be put on one end of the connector 7 located in the connecting tube 6 and the limiting tube 11 to further improve the sealing effect and prevent cross infection caused by extravasation of effusion.

[0029] The hose 10 is covered with a protective tube 9 for preventing the hose 10 from being deformed under pressure. The protective tube 9 is a steel hose, which has a certain hardness and toughness and can be bent to a certain extent. Thus, the protective tube 9 can prevent the hose 10 from being blocked when under pressure and prevent the hose 10 from bending during the patient's daily activities, thereby ensuring the smooth flow of the hose 10 and improving the safety of drainage.

[0030] One end of the protection tube 9 is sleeved with a connecting sleeve 14 that is rotatably matched therewith. The connecting sleeve 14 is sleeved on the limiting tube 11 and is threadedly matched therewith. By screwing the connecting sleeve 14 on the limiting tube 11, the protection tube 9 can be detachably installed on the limiting tube 11, thereby preventing the protection tube 9 from sliding on the hose 10. At the same time, the protection tube 9 does not contact the accumulated fluid and can be reused after disinfection. Figure 1 and Figure 2 As shown, one end of the protective tube 9 equipped with the connecting sleeve 14 is fixed with a limiting plate 13 for preventing the connecting sleeve 14 from sliding out of the end, and the limiting plate 13 prevents the connecting sleeve 14 from separating from the protective tube 9, and at the same time does not hinder the rotation of the connecting sleeve 14, such as the installation of the gas pipeline and the liquefied gas tank, wherein the connecting sleeve 14 is a circular groove structure opening to the right, a through hole for the protective tube 9 to pass through is provided at the bottom of the groove, an internal thread is provided on the groove wall, and an external thread is provided on the outer wall of the limiting tube 11, the limiting plate 13 is an annular structure, and the inner diameter is the same as the inner diameter of the protective tube 9, and the outer diameter is larger than the aperture of the through hole but less than or equal to the inner diameter of the connecting sleeve 14.

[0031] When the present embodiment is in use, the protective tube 9 is firstly put on the hose 10, and then the connector 7 is horizontally inserted into the connecting tube 6 until the annular protrusion 12 is stuck in the annular groove of the limiting tube 11, and then the connecting sleeve 14 is rotated to be tightened on the limiting tube 11, and then the top plate 5 is pressed downward until the liquid storage bag 4 is completely compressed and the regulating valve on the other end of the hose 10 is closed, and then the other end of the hose 10 is connected to the inserted gastric tube, and finally the regulating valve is opened to start the drainage, and the medical staff observes and records the color, nature and amount of the drainage in the liquid storage bag 4.

[0032] Example 2

[0033] This embodiment further illustrates the technology, and also includes a limiting plate 2 in an annular structure, the limiting plate 2 and the liquid storage bag 4 are made of the same material, the top plate 5 is fixed in the upper end of the limiting plate 2, and the bottom plate 1 is fixed in the lower end of the limiting plate 2. Figure 1 As shown, wrapping the top plate 5, the liquid storage bag 4, the spring 3 and the bottom plate 1 with the limiting plate 2 can not only prevent the spring 3 from bending outward when compressed, but also play an aesthetic role. At the same time, the limiting plate 2 is also made of transparent PVC material to avoid hindering medical staff from observing the drainage material and scale lines in the liquid storage bag 4.

[0034] Example 3

[0035] This embodiment further illustrates the technology. A hook 8 is installed on the top of the connecting pipe 6, and the hook 8 is convenient for hanging the device on the edge of the patient's bed or the bottom of the bed. Figure 1 As shown, the hook 8 is spherically hinged on the top of the connecting tube 6, so that it can rotate freely in the horizontal direction relative to the connecting tube 6, so that the scale line of the liquid storage bag 4 is facing outward, which is convenient for medical staff to observe.
