Description

TECHNICAL FIELD

[0001] The utility model relates to a stomach tube technical field especially, it relates to a novel stomach tube assembly. BACKGROUND

[0002] The stomach tube is used to help the patient who cannot swallow to transport necessary moisture and food under special circumstances. The stomach tube is generally polyurethane or silica gel material, according to the material, polyurethane, silica gel stomach tube should be replaced every month.

[0003] The existing stomach tube is inserted from the nose, and it is required to reach the stomach, but it is actually easy to be misinserted into the lung (because the trachea and the stomach tube inlet of the human body are closely adjacent). If it is accidentally inserted into the lung, it is easy to cause infection and death, and there have been many reports in the news. Therefore, in order to prevent misinsertion, after being inserted, three checks need to be done: CT, auscultation, and PH value measurement of the extracted liquid. This kind of way is more cumbersome.

[0004] Therefore, at present, some hospitals set a PH sensor at the end of the stomach tube to monitor the pH value of the end of the stomach tube in real time (the lung fluid: the pH value is usually between 7.38 to 7.42, close to neutral, slightly alkaline. The stomach fluid: mainly refers to gastric acid, and the pH value is very low, usually between 1.5 to 3.5, strong acid), so as to judge whether the position of the stomach tube is correct. However, in this way, the sensor enters the stomach of the patient along with the stomach tube, which not only causes the sensor to be damaged by the strong acid environment of the stomach, but also affects the patient to eat through the stomach tube.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model technical scheme will be described clearly and completely in combination with specific embodiments of the utility model and corresponding drawings below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0029] The technical scheme provided by each embodiment of the utility model will be described in detail below in combination with the drawings.

[0030] Referring to Figures 1 to 6 The utility model embodiment provides a novel stomach tube assembly, including hose 1, joint part 2, gastroesophageal pH meter 3 and clamp 4. Hose 1 is used as stomach tube for inserting into the stomach of patient.

[0031] Joint part 2 has a passageway 21, and the passageway 21 is communicated with the hose 1, and the joint part 2 is installed on one end of the hose 1, and in some practical applications, such as Figures 2 to 4 As shown in the figure, detachable connection is adopted between the joint part 2 and the hose 1, which is convenient for installation and maintenance of the assembly. Specifically, the joint part 2 is configured as a tubular structure, one end of which is provided with a flange 22, and the internal cavity of the tubular structure is the passageway 21, and one end of the hose 1 is sleeved on the tubular structure in an interference fit manner.

[0032] The gastroesophageal pH meter 3 is a prior art, mainly having a detection probe 32 connected through a wire 31, and the detection probe 32 is electrically connected with the host 33 of the whole gastroesophageal pH meter 3 through the wire 31, and when the medical staff performs the stomach tube insertion on the patient, the detection probe 32 is previously inserted into the hose 1 and placed at the other end of the hose 1, and then the tube insertion operation is performed, and in the tube insertion process, the gastroesophageal pH meter 3 can judge the pH value tested by the detection probe 32, so as to judge whether the position of the tube insertion is correct, and avoid the transmission into the trachea of the patient; in addition, after the hose 1 correctly enters the stomach of the patient, the gastroesophageal pH meter 3 can be directly drawn out from the inside of the hose 1, compared with directly setting a fixed pH detector at the end of the hose 1, which avoids the damage caused by the long-term pH detector in the stomach of the patient, and also eliminates the influence on the normal eating of the patient caused by the obstruction of the pH detector.

[0033] The clamp 4 is installed on the joint part 2 to clamp the wire 31, mainly to avoid the change of the position of the detection probe 32 when the hose 1 is inserted into the stomach of the patient, to keep the synchronization among the wire 31, the hose 1 and the detection probe 32, to ensure that the detection probe 32 is still stably at the end of the hose 1 after the hose 1 is inserted in place, so as to facilitate the real-time environment pH detection, and effectively improve the detection precision.

[0034] In some practical applications, such as Figures 2 to 5 As shown, the clamping component 4 includes two clamping blocks 41, which are positioned opposite each other on the side of the connector 2 away from the hose 1 with the axis of the channel 21 as the center line. The two clamping blocks 41 can move towards each other to clamp the wire 31. Rubber pads 42 are installed on the inner ends of the clamping blocks 41 to protect the wire 31 from being scratched. At the same time, the rubber material has insulation properties to avoid affecting the detection results of the gastroesophageal pH meter 3.

[0035] Based on the above embodiments, the clamping component 4 has been further optimized.

[0036] like Figures 2 to 5 As shown, the clamping member 4 also includes two sliding parts 43. Both sliding parts 43 are slidably connected to the joint part 2 along the moving direction of the clamping block 41 and are respectively located on the outside of the two clamping blocks 41. Each sliding part 43 is elastically connected to the corresponding clamping block 41.

[0037] Specifically, the sliding end 432 on the bottom side of each sliding part 43 is slidably connected to the groove 24 on the surface of the connector 2 to achieve a sliding fit between the sliding part 43 and the clamping block 41. In addition, a ring 5 is coaxially fixedly installed on the flange 22. The ring 5 blocks the groove 24 and limits the sliding part 43 to prevent it from falling out of the groove 24. Similarly, a positioning tube 6 is also installed at the top of the tubular structure. The positioning tube 6 is connected to the connector 2 by a threaded connection, and the upper end of the positioning tube 6 is provided with an outwardly extending limiting part 61. That is, when the sliding part 43 abuts against the limiting part 61, the insertion rod 44 is exactly above the corresponding insertion hole 23, so that the insertion rod 44 can be smoothly inserted into the insertion hole 23. The limiting part 61 mainly serves a positioning function.

[0038] Specifically, the connection between the sliding part 43 and the clamping block 41 is further optimized: each clamping block 41 has a laterally extending guide post 411 at its outer end. The guide post 411 passes through the sliding part 43 corresponding to the clamping block 41 and slides with it. A first spring 412 is sleeved on the guide post 411. The first spring 412 is located between the guide post 411 and the clamping block 41 to elastically support the clamping block 41. A limit plate 413 is installed at the end of the guide post 411 away from the clamping block 41.

[0039] In other practical applications, such as Figures 2 to 5As shown, a locking point is added in the movement process of the sliding part 43, that is, when the sliding part 43 moves to the set position, the two clamping blocks 41 are ensured to clamp the wire 31, and the sliding part 43 can be locked on the joint part 2. Specifically, a longitudinally extending perforation 431 is arranged on each sliding part 43, and a plug rod 44 is inserted in the perforation 431. The joint part 2 is provided with a plug hole 23 which is in plug-in cooperation with the plug rod 44. When the plug rod 44 moves to the plug hole 23, the plug rod 44 can be embedded in the plug hole 23 to lock the sliding part 43 during the movement of the sliding part 43 to the channel 21. In addition, the end of the plug rod 44 away from the plug hole 23 can be provided with a ball part 441 to facilitate the user to pull the plug rod 44 to move.

[0040] In some practical applications, further optimization is made based on the plug rod 44. Specifically, as shown, Figure 3 Each end of the sliding part 43 close to the joint part 2 is provided with a mounting groove 433, and a second spring 434 is mounted in the mounting groove 433. The end of the second spring 434 close to the joint part 2 elastically abuts against a protrusion 442 on the outer wall of the plug rod 44, so that the plug rod 44 is elastically abutted against the joint part 2.

[0041] The operation principle of the clamping piece 4 is as follows: when the clamping operation is needed, the operator can move the sliding part 43 transversely by pressing, so that the clamping block 41 moves to the center line, and then the wire 31 is clamped. At this time, the first spring 412 is compressed, and the elastic potential energy is stored. When the operator releases the sliding part 43, the first spring 412 releases the elastic potential energy and pushes the clamping block 41 back to the original position.

[0042] The limiting plate 413 functions to limit the movement range of the clamping block 41 during the clamping operation, so as to prevent the clamping block 41 from moving excessively and damaging the wire 31 or other parts of the clamping piece 4.

[0043] At the connection between the sliding part 43 and the clamping block 41, the cooperation of the guide column 411 and the first spring 412 realizes the adjustability of the clamping force. The operator can adjust different springs according to the thickness of the wire 31 and the required clamping degree, so as to achieve the best clamping effect.

[0044] During the maintenance and replacement of the assembly, the clamping block 41 and the sliding part 43 can be easily disassembled and assembled due to the structural design of the clamping piece 4, which facilitates the maintenance work of the assembly.

[0045] In the embodiment, the locking mechanism of the plug rod 44 and the plug hole 23 is adopted, so that the sliding part 43 will not move under the action of external force in the locked state, and the stability and safety of the wire 31 are ensured.

[0046] Through the above structural design and implementation mode, the novel stomach tube assembly of the embodiment not only improves the fixing stability of the guide wire 31, but also improves the overall reliability and service life of the assembly.

[0047] In addition, the outer side end of each sliding part 43 is provided with a shell 435, and the outer surface of the shell 435 is provided as a smooth curved surface. The shell 435 is mainly provided to improve the overall structure of the appearance, and the guide column 411 can be hidden, and the user can push the shell 435 to move the sliding part 43, so as to avoid that only the sliding part 43 causes the guide column 411 to affect the hand feeling of the user.

[0048] The above only describes the embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
