[0001] The present application relates to the technical field of gastric fluid pH value detection instruments, and in particular to a gastric tube flusher capable of automatically detecting gastric fluid pH value. Background Art

[0002] Gastric fluid pH testing is an important tool for assessing gastric health. Normal gastric fluid pH is between 0.9 and 1.5. By testing a patient's gastric fluid pH, we can determine whether it is elevated or depressed, providing a preliminary assessment of conditions such as gastric cancer, iron-deficiency anemia, gastric ulcers, and chronic gastritis. Current methods for testing gastric fluid pH are typically performed using a pH meter or test strips on sampled gastric fluid.

[0003] Clinically, patients who require prolonged monitoring of gastric fluid pH require medical staff to daily draw gastric fluid from an indwelling gastric tube using a syringe, then inject the fluid into a test container. Finally, the fluid in the test container is tested using a pH meter or test strips. However, the injection of the fluid into the test container, as well as the testing and handling of the fluid in the test container, can easily drip or spill onto the skin of medical staff, increasing their exposure to gastric fluid and posing a high risk of biological contamination.

[0030] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0031] The utility model provides Figures 1 to 3 As shown in , a gastric tube flusher that can automatically detect the pH value of gastric juice is intended to solve the disadvantage of existing instruments for detecting the pH value of gastric juice, which have a high risk of biological contamination.

[0032] The gastric tube flusher capable of automatically detecting the pH value of gastric fluid primarily comprises a syringe 100 and a pH detector 200. The syringe 100 is used to collect gastric fluid and flush the gastric tube, while the pH detector 200 is used to detect the pH value of the gastric fluid drawn by the syringe 100. Specifically, a medical professional connects the syringe 100 to an indwelling gastric tube and uses the syringe 100 to draw gastric fluid. During this process, the gastric fluid comes into contact with the pH detector 200, which detects the pH value of the gastric fluid, thereby reducing the chance of gastric fluid coming into contact with the medical professional.

[0033] The pH detector 200 includes a detector body 210, a gastric fluid channel 230, and a pH sensor 220. The detector body 210 is detachably connected to the syringe 100. Specifically, the detector body 210 can be detachably connected to the syringe 100 by means of a snap-on connection, adhesive bonding, or sleeve connection. When the pH of gastric fluid is no longer needed, the detector body 210 can be removed from the syringe 100 for cleaning.

[0034] The gastric fluid channel 230 is provided on the detector body 210. One end of the gastric fluid channel 230 is connected to the nipple 110 of the syringe 100, and the other end is provided at the end of the detector body 210 facing away from the syringe 100. Specifically, when the medical staff pushes the syringe 100 to extract gastric fluid, the syringe 100 will extract the gas in the gastric fluid channel 230, thereby forming a negative pressure environment in the gastric fluid channel 230. The gastric fluid enters the gastric fluid channel 230 through the opening of the gastric fluid channel 230 facing away from the syringe 100, and then enters the syringe 100.

[0035] The pH sensor 220 is disposed within the gastric fluid passage 230 and is used to detect the pH of gastric fluid flowing through the gastric fluid passage 230. During actual use, as medical personnel extract gastric fluid, the fluid passes through the gastric fluid passage 230 and syringe 100. During this process, the pH sensor 220 can detect the gastric fluid, eliminating the need to inject the gastric fluid in syringe 100 into a test container for testing. This minimizes the chance of gastric fluid coming into contact with medical personnel and reduces the risk of biological contamination.

[0036] Clinically, patients who require long-term monitoring of gastric fluid pH require medical staff to daily draw gastric fluid from an indwelling gastric tube using a syringe 100, then inject the fluid into a test container using the syringe 100. Finally, the fluid in the test container is tested using a pH meter or test paper. However, during the injection of the fluid from the syringe 100 into the test container, as well as during testing and handling of the fluid in the test container, the fluid can easily drip or spill onto the skin of medical staff, increasing their exposure to gastric fluid and posing a risk of biological contamination.

[0037] The present invention provides a gastric juice channel 230 on the detector body 210. When medical staff extract gastric juice, the gastric juice passes through the gastric juice channel 230 and the syringe 100 in sequence. At this time, the pH sensor 220 located in the gastric juice channel 230 can detect the gastric juice without injecting the gastric juice in the syringe 100 into the test container for testing, thereby reducing the chance of gastric juice coming into contact with medical staff and reducing the risk of biological contamination.

[0038] In some embodiments, as Figure 3As shown in the figure, the acid-base value detector 200 further comprises a detection channel 240, which is arranged in the detector body 210 and one end of the detection channel 240 is communicated with the gastric juice channel 230, the detection channel 240 and the gastric juice channel 230 form a "Y" shape structure, and the acid-base value sensor 220 is arranged in the detection channel 240.

[0039] Specifically, during the process of extracting gastric juice by medical staff, the gastric juice flows into the syringe 100 through the gastric juice channel 230, and the detection channel 240 is equivalent to a branch connected to the gastric juice channel 230, at this time, part of the gastric juice will enter the detection channel 240, and the acid-base value sensor 220 can detect the acid-base value of the gastric juice entering the detection channel 240.

[0040] In some embodiments, as shown in the figure, Figure 3 As shown in the figure, during the process of extracting gastric juice by medical staff, the gastric juice flows from the end of the gastric juice channel 230 away from the syringe 100 to the end of the gastric juice channel 230 towards the syringe 100, and since the included angle between the end of the detection channel 240 away from the gastric juice channel 230 and the end of the gastric juice channel 230 towards the syringe 100 is less than 90 degrees, the gastric juice is more likely to enter the detection channel 240, and a small amount of gastric juice is sufficient to enter the detection channel 240, and the acid-base value sensor 220 can detect the acid-base value of the gastric juice entering the detection channel 240.

[0041] In some embodiments, as shown in the figure, Figure 3 As shown in the figure, the detector body 210 comprises a connecting part 211, a sleeve part 212 and a suction tube part 213.

[0042] The connecting part 211 is detachably connected with the syringe 100, specifically, the connecting part 211 can be detachably connected with the syringe 100 by clamping, bonding, sleeving and the like, preferably sleeving, and the diameter can be changed to match syringes 100 of different specifications. When the acid-base value of the gastric juice does not need to be detected, the detector body 210 can be detached from the syringe 100 for cleaning.

[0043] The sleeve part 212 is connected with the connecting part 211, the sleeve part 212 is sleeved on the nipple 110 of the syringe 100, and the gap between the sleeve part 212 and the nipple 110 of the syringe 100 forms the detection channel 240, the gastric juice channel 230 is arranged through the suction tube part 213, one end of the suction tube part 213 is connected with the opening of the sleeve part 212 away from the syringe 100, and the other end forms a suction port, which is used for sucking gastric juice. Specifically, the detection channel 240 has only one opening connected with the gastric juice channel 230.

[0044] In some embodiments, as shown in the figure, Figure 3As shown in FIG, the detector body 210 further includes a flow guide 214 disposed on the collar portion 212. The end of the flow guide 214 facing the syringe 100 is located within the nipple 110 of the syringe 100. The gap between the flow guide 214 and the nipple 110 of the syringe 100, the detection channel 240, and the gastric fluid channel 230 form a "Y"-shaped structure. Specifically, the flow guide 214, the connecting portion 211, the collar portion 212, and the straw portion 213 are all made of the same material as the syringe 100 to prevent corrosion from gastric fluid.

[0045] In some embodiments, as Figure 3 As shown in the figure, the inner diameter of the detection channel 240 gradually decreases in the direction toward the gastric juice channel 230. Specifically, the cross-sectional area of ​​the detection channel 240 in the axial direction of the syringe 100 gradually increases in the direction toward the syringe 100, so that the gastric juice entering the detection channel 240 can be better retained in the detection channel 240 and is not easy to flow out and contact with medical staff.

[0046] In some embodiments, as Figures 1 to 3 As shown in , the pH value detector 200 further includes: a display screen 250 , which is disposed on the detector body 210 , and is used to display information output by the pH value sensor 220 .

[0047] In some embodiments, as Figures 1 to 3 As shown in FIG, the detector body 210 has an upper end and a lower end opposite to each other, and the upper end and the lower end are both arranged along the radial direction of the syringe 100. The display screen 250 and the pH value sensor 220 are respectively arranged at the upper end and the lower end of the detector body 210. Specifically, in actual use, as shown in FIG. Figure 3 As shown in FIG, the nipple 110 of the syringe 100 is facing leftward to aspirate gastric fluid, and the display screen 250 is facing upward for easy observation by medical staff, and the pH sensor 220 is facing downward for easy contact with the gastric fluid flowing into the detection channel 240.

[0048] In some embodiments, the pH detector 200 further includes a magnetic base disposed on the detector body 210, with a display screen 250 detachably connected to the magnetic base. Preferably, a control circuit is disposed on the display screen 250, and the control circuit and the display screen 250 are electrically connected to the pH sensor 220 via the magnetic base. When the pH detector 200 needs to be disassembled for cleaning or discarded, the display screen 250 can be removed to protect it or reuse it, thereby reducing operating costs.

[0049] In some embodiments, as Figures 1 to 2As shown in FIG, the gastric tube irrigator further includes a blocking cap 300, which is configured to fit over the suction tube portion 213 and seal the liquid suction port of the suction tube portion 213. In actual use, when the pH detector 200 is not needed, the blocking cap 300 can be placed over the liquid suction port to prevent gastric fluid from dripping and contacting medical personnel.

[0050] In summary, a gastric tube flusher that can automatically detect the pH value of gastric fluid is provided, comprising a syringe and a pH detector, the pH detector comprising: a detector body detachably connected to the syringe, a gastric fluid channel provided on the detector body, and a pH sensor provided in the gastric fluid channel, one end opening of the gastric fluid channel being connected to the nipple of the syringe, and the other end opening being provided at the end of the detector body facing away from the syringe. The utility model provides a gastric fluid channel on the detector body, and in the process of medical staff extracting gastric fluid, the gastric fluid passes through the gastric fluid channel and the syringe in sequence. At this time, the pH sensor located in the gastric fluid channel can detect the gastric fluid, without the need to inject the gastric fluid in the syringe into a test container for testing, thereby reducing the chance of gastric fluid coming into contact with medical staff and lowering the risk of biological contamination.
