Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a gastric tube connector. Background Art

[0002] The single-connector gastric tube design widely adopted in current front-line medical practice mainly falls into two types: with a guide wire and without a guide wire. While providing liquid food feeding, if drug injection needs to be carried out simultaneously, it faces a complex process of having to remove the feeding tube, perform drug infusion, and then reconnect. This process not only increases the complexity of nursing operations but also significantly weakens the cleanliness and aseptic standards of the operations. For patients with severe conditions during hospitalization, it is difficult to meet their treatment needs of receiving nutritional support and drug treatment simultaneously. Also, after the initial insertion of the gastric tube, the process of confirming its correct position (i.e., whether it has entered the stomach instead of mistakenly entering the trachea) is equally cumbersome and requires high skills. Usually, it is necessary to judge by means of aspirating gastric juice, observing bubbles, or using a stethoscope, etc. These steps, especially in home care for non-medical professionals, have the possibility of operation errors and misjudgments, increasing the discomfort of patients during the operation.

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the solution of the present invention will be further described below. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0030] The gastric tube connector of the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0031] As Figure 1 and Figure 2 shown, the gastric tube connector of the embodiment of the present invention may include a main pipe 1, a first insertion pipe 2, a second insertion pipe 3, a cap 4, a diaphragm 5 and a detection mechanism 6.

[0032] Among them, the bottom end of the main pipe 1 is used to connect to the gastric tube.

[0033] It should be noted that during use, the injection end of the gastric tube can be sleeved into the bottom end of the main pipe 1, and there is an interference fit between the main pipe 1 and the gastric tube, so as to achieve a tight fit between the gastric tube and the main pipe 1.

[0034] The first insertion pipe 2 and the second insertion pipe 3 are respectively communicated with the main pipe 1, and caps 4 matching them are respectively clamped on the first insertion pipe 2 and the second insertion pipe 3.

[0035] Among them, it can be understood that setting the cap 4 can block the first insertion pipe 2 and the second insertion pipe 3. On the one hand, it can effectively prevent external pollutants such as dust, moisture, and bacteria from entering the inside of the first insertion pipe 2 or the second insertion pipe 3, ensuring the cleanliness and sterility of the interfaces of the first insertion pipe 2 and the second insertion pipe 3. On the other hand, it can avoid scratches and impacts on the interfaces of the first insertion pipe 2 and the second insertion pipe 3, and at the same time can avoid the backflow of liquid, reducing the complexity of nursing. At the same time, when the detection mechanism 6 detects the pressure of the gastric tube, it can avoid the situation that the detection accuracy is reduced due to gas leakage.

[0036] The diaphragm 5 is disposed in the main tube 1, and the diaphragm 5 has air permeability and water impermeability.

[0037] It can be understood that the air-permeable characteristic of the diaphragm 5 can ensure the air circulation when judging whether the gastric tube has entered the stomach rather than the trachea by mistake after the initial insertion of the gastric tube, and allows the gas to smoothly penetrate through the diaphragm 5 and contact the detection mechanism 6. The water-impermeable characteristic of the diaphragm 5 can effectively block the reverse flow of gastric juice in the pathological conditions such as gastroesophageal reflux and functional dyspepsia that may cause gastric juice reflux, and avoid the corrosive gastric juice directly contacting and damaging the detection mechanism 6, thereby prolonging the service life of the detection mechanism 6.

[0038] The detection mechanism 6 includes a plug 60, a pressure sensor 61, a prompting component 62 and a controller 63.

[0039] Part of the plug 60 is clamped into the main tube 1.

[0040] It should be noted that, in order to ensure the tightness between the plug 60 and the main tube 1, an interference fit is provided between the plug 60 and the main tube 1 to prevent the entry of external gas.

[0041] The pressure sensor 61 is embedded at the bottom end of the plug 60, and the diaphragm 5 is arranged between the communication interfaces of the first insertion tube 2 and the second insertion tube 3 with the main tube 1 and the pressure sensor 61. The prompting component 62 and the controller 63 are respectively arranged at the top end of the plug 60, and the controller 63 is electrically connected to the prompting component 62 and the pressure sensor 61 respectively.

[0042] It should be noted that the pressure sensor 61, the prompting component 62 and the controller 63 described in this embodiment can all be connected to the external mains power to supply power to the pressure sensor 61, the prompting component 62 and the controller 63. Among them, the pressure sensor 61 is used to detect the air pressure change inside the gastric tube. Since the stomach is a part of the digestive system, the internal pressure is usually regulated by the volume change of the gas and food in the stomach and the contraction of the gastric wall. Under normal circumstances, the pressure inside the stomach is slightly higher than the external atmospheric pressure, but the change range is relatively small and remains within a relatively stable range. The trachea is a part of the respiratory system, and the pressure of the gas contained therein is caused by the respiratory action (inhalation and exhalation). In contrast, the trachea is the core channel of the respiratory system, and the internal gas pressure changes significantly with the rise and fall of the respiratory process. During inhalation, the pressure inside the trachea is lower than the outside, forming a negative pressure; during exhalation, it is higher than the outside, presenting a positive pressure. This large-amplitude fluctuation of the pressure caused by the respiratory action can be detected by the pressure sensor 61 to judge whether the gastric tube is inserted into the stomach or the trachea, so as to distinguish whether it is inserted into the stomach or the trachea according to the change of the air pressure.

[0043] Specifically, in the actual operation process, the gastric tube can be set on the outer wall of the bottom end of the main tube 1, and the medical staff or home care staff inserts the gastric tube through the patient's nasal cavity. After the gastric tube is inserted, since the air pressure in the gastric tube inserted into the stomach and the gastric tube inserted into the trachea is different, the pressure sensor 61 is used to detect the change in air pressure in the gastric tube, and the detection data is sent to the controller 63 for intelligent analysis.

[0044] The controller 63 has a built-in algorithm (such as a threshold comparison algorithm) that can accurately determine whether the air pressure change exceeds a preset safety threshold range. If the controller 63 determines that the air pressure change is abnormal, that is, exceeds the preset range, the prompt component 62 is immediately activated to issue a clear warning to quickly remind the nursing staff to check and adjust the position of the gastric tube to reduce the patient's discomfort during the operation.

[0045] On the contrary, if the controller 63 confirms that the air pressure change is within the preset safety threshold range, it indicates that the gastric tube has been successfully inserted into the stomach. At this time, the prompt component 62 remains silent to avoid unnecessary interference. For non-medical professionals, the probability of misjudgment is greatly reduced. The preset safety threshold range can be verified by experiments and clinical trials to obtain reliable pressure data and adjust the threshold. For example, when the gastric tube is correctly inserted into the stomach, its internal air pressure is usually maintained at a relatively low level of (1±0.45) cmH2O; once it enters the trachea by mistake, the air pressure will rise sharply to around (7±2.03) cmH2O, and the preset safety threshold range can be set to (1±0.45) cmH2O.

[0046] The pressure sensor 61 also has another important function of monitoring the blockage of the gastric tube. During the process of drug administration or feeding, if the gastric tube is blocked, the pressure inside the tube will increase abnormally. Once the preset pressure threshold (which can be set according to actual conditions) is exceeded, the controller 63 will immediately activate the prompt component 62 to remind the nursing staff to take timely unblocking measures to effectively avoid the serious consequences of complete blockage of the gastric tube.

[0047] And by designing two independent interfaces, the first plug-in tube 2 and the second plug-in tube 3. When feeding, any interface can be selected to connect the feeding injection tube; and when administering medicine, ensure that the injection tube is connected to an interface different from the feeding tube. This separate design not only avoids the cleaning and sterility problems that may be caused by cross-use of interfaces, but also ensures that the patient can receive dual treatment of drugs and fluids (such as nutrient solution) at the same time to ensure the patient's recovery process.

[0048] In addition, considering that the main pipe 1 may need to be replaced due to contamination or other factors, the replaceable design allows the detection mechanism 6 to be pulled out of the old main pipe 1 and then connected to a new main pipe 1 for reuse. This innovative design not only simplifies the replacement process, but also significantly reduces the cost of use.

[0049] In an embodiment of the present utility model, as Figure 1 shown, the caliber of the main pipe 1 near one end of the plug 60 is larger than the caliber of the main pipe 1 near the gastric tube end.

[0050] Specifically, according to the above design, it can not only meet the adaptability during the connection of the gastric tube, ensure the stability when the gastric tube is connected to the main pipe 1, but also meet the installation requirements of the detection mechanism 6.

[0051] In an embodiment of the present utility model, as Figure 1 shown, the joint calibers of the first insertion tube 2 and the second insertion tube 3 are different.

[0052] Among them, it can be understood that the joint design with different calibers enables the first insertion tube 2 and the second insertion tube 3 to be respectively connected to injection tubes of different specifications, thereby improving the applicability and flexibility of the entire gastric tube joint.

[0053] In an embodiment of the present utility model, the diaphragm 5 is a waterproof and breathable membrane.

[0054] It should be noted that the waterproof and breathable membrane has the characteristics of water isolation and air permeability, as well as corrosion resistance, which ensures unobstructed gas flow when the detection mechanism 6 detects the pressure in the gastric tube, enables the gas to smoothly pass through the diaphragm 5, thereby ensuring the accuracy and real-time nature of the pressure detection. At the same time, in the face of potential fluid intrusion such as gastroesophageal reflux, the water isolation property can effectively block the penetration of the fluid, avoiding the direct contamination and corrosion risk to the detection mechanism 6, thereby improving the working stability and service life of the detection mechanism 6.

[0055] In an embodiment of the present utility model, the prompt component 62 is one or more of a warning light and a buzzer.

[0056] Specifically, the warning light can be used to warn (remind) the nursing staff of the situation where the gastric tube is inserted into the wrong position and the gastric tube is blocked. Among them, the situation where the gastric tube is inserted into the wrong position or the gastric tube is blocked can be distinguished by the light color of the warning light. For example, when the gastric tube is inserted into the wrong position, the warning light lights up red, and when the gastric tube is blocked, the warning light lights up green.

[0057] Or the buzzer can be used to remind the nursing staff of the situation where the gastric tube is inserted into the wrong position and the gastric tube is blocked. Among them, the situation where the gastric tube is inserted into the wrong position or the gastric tube is blocked can be distinguished by the volume of the buzzer. For example, when the gastric tube is inserted into the wrong position, the buzzer will emit a sharp and rapid sound to attract the urgent attention of the nursing staff; if it is detected that the gastric tube is blocked, it may emit a low or continuous sound so that the nursing staff can identify and take corresponding measures.

[0058] Alternatively, by using a warning light and a buzzer in combination, a dual reminder function is achieved to ensure that the problem of the gastric tube being inserted into the wrong position is discovered and corrected in the first time, thus ensuring the safety and comfort of the patient.

[0059] In an embodiment of the present utility model, as Figure 1 shown, a pull cord 7 is connected between the first insertion tube 2 and the corresponding cap 4 and / or between the second insertion tube 3 and the corresponding cap 4.

[0060] Specifically, setting the pull cord 7 can limit the position of the cap 4, effectively preventing the cap 4 from falling off or being lost inadvertently.

[0061] In an embodiment of the present utility model, as Figure 2 shown, the detection mechanism 6 further includes a battery module 64. The battery module 64 is installed in the installation cavity 600 opened at the top end of the plug 60, and the battery module 64 is electrically connected to the pressure sensor 61, the prompting component 62 and the controller 63 respectively.

[0062] It should be noted that the battery module 64 may include a battery, and a corresponding charging circuit and a charging protection circuit are arranged in the battery module 64. Further, the battery may be a lithium-ion battery. Since the structure of the battery module 64 is a prior art, it will not be elaborated here.

[0063] Specifically, by setting the battery module 64, the pressure sensor 61, the prompting component 62 and the controller 63 can be powered, completely getting rid of the bondage of relying on an external power supply, making it more flexible and convenient to use, and greatly improving the user experience.

[0064] Further, as Figure 1 shown, the above gastric tube connector further includes a charging socket 8. The charging socket 8 is embedded in the plug 60, and the charging socket 8 is electrically connected to the battery module 64.

[0065] Specifically, by setting the charging socket 8, it is convenient to charge the battery module 64, considering the convenience needs of users, making the charging process simple and convenient. Among them, the charging socket 8 can be one of a USB interface, a Lightning interface, and a Type-C interface, which can be selected according to actual situations.

[0066] In an embodiment of the present utility model, as Figure 2 、 Figure 3 and Figure 4 shown, the detection mechanism 6 further includes a plugging mechanism 65. The plugging mechanism 65 is snap-connected in the installation cavity 600, and the plugging mechanism 65 is arranged above the battery module 64.

[0067] Specifically, the blocking mechanism 65 is provided to effectively prevent collisions and impacts that may occur during daily use, and the limiting function is also played to ensure the stable installation of the battery module 64, thereby improving the service life of the battery module 64.

[0068] Furthermore, the connection between the blocking mechanism 65 and the installation cavity 600 adopts a quick snap-in method, so that the user can easily install and disassemble the blocking mechanism 65, greatly improving the convenience of operation.

[0069] In order to further clarify the above embodiment, in one embodiment of the present utility model, as shown in FIG. Figure 3 and Figure 4 As shown, the blocking mechanism 65 includes a cover plate 650 , two symmetrically arranged insert blocks 651 and a clamping plate 652 .

[0070] Among them, the plug block 651 and the card plate 652 are respectively fixed on the cover plate 650, and the plug block 651 and the card plate 652 are arranged relatively to each other. Two first limiting grooves 601 are provided on the inner wall of the installation cavity 600, and a second limiting groove 602 is also provided on the plug 60. When the cover plate 650 is clamped in the installation cavity 600, the two plug blocks 651 are respectively inserted into the corresponding first limiting grooves 601, and the card plate 652 is clamped into the second limiting groove 602. The card plate 652 is V-shaped, and the shape and size of the card plate 652 are adapted to the shape and size of the second limiting groove 602, and the shape and size of the plug block 651 are adapted to the shape and size of the first limiting groove 601.

[0071] It can be understood that the first limiting groove 601 and the plug block 651 can limit the cover plate 650, effectively preventing accidental displacement during use. The V-shaped design of the clamping plate 652, which is closely matched with the second limiting groove 602, further enhances the tensioning and limiting ability of the cover plate 650 in the installation cavity 600, thereby ensuring the stability of the cover plate 650 in the installation cavity 600. By moving the clamping plate 652, the tension on the cover plate 650 can be released, and then the cover plate 650 can be taken out, which is simple and convenient to operate.

[0072] In summary, the gastric tube connector of the embodiment of the utility model can avoid the cleaning and sterility problems that may be caused by the cross-use of interfaces, and ensure that the patient can receive dual treatment of drugs and fluids at the same time to ensure the patient's recovery process. At the same time, it can also help non-medical professionals reduce the probability of misjudgment caused by operational errors, so as to reduce the discomfort of patients during the operation.
