Medical equipment is the most basic element of medical treatment, scientific research, teaching, institutions, and clinical disciplines, including professional medical equipment and home medical equipment. When sucking gastric juice from the patient's stomach, a special negative pressure suction bottle is used to suck the internal gastric juice.

[0003] The current negative pressure suction bottle mainly consists of two parts, an insertion tube and a negative pressure bottle that provides negative pressure and collects liquid. The cannula can be inserted inside, and then the negative pressure bottle can be squeezed to form negative pressure to absorb the gastric juice in the patient's stomach. However, this structure has certain problems when used, that is, there is no component specifically for infants. Because infants have less gastric juice and the negative pressure bottle itself is spring-shaped, some gastric juice will remain in the spring-shaped groove inside the negative pressure bottle and cannot be poured out, affecting the final calculated amount of gastric juice, resulting in the overall detection effect being affected and the final monitoring data being biased. Therefore, the present application provides a negative pressure suction bottle to meet the needs. Utility Model Content

[0032] like Figures 1 to 5 As shown, an embodiment of the utility model provides a negative pressure suction bottle, including a negative pressure bottle 1, an air supply pipe 4 is fixedly installed on the top of the negative pressure bottle 1, a collecting bottle 2 is arranged on the top of the air supply pipe 4, an air suction nozzle 5 is fixedly installed inside the collecting bottle 2, and the top outlet part of the air suction nozzle 5 is provided with a waterproof and breathable membrane, and the air suction nozzle 5 itself is in a conical shape, the bottom end of the air suction nozzle 5 is fixedly connected to the air supply pipe 4, and a cannula 3 is fixedly installed on one side of the top of the collecting bottle 2. During use, the negative pressure bottle 1 is pressed, and the change of the internal air pressure of the negative pressure bottle 1 and the cooperation of the air supply pipe 4 are utilized to change the internal pressure of the collecting bottle 2, and then the change of the internal pressure of the collecting bottle 2 is utilized to make the cannula 3 suck the gastric juice from the stomach of the infant, and the gastric juice will be concentrated and stored inside the collecting bottle 2, because the shape and height of the air suction nozzle 5 itself prevent the gastric juice from continuing to flow into the subsequent negative pressure bottle 1, so that the collection of gastric juice is more stable and concentrated, and the subsequent pouring out and collection are also more convenient.

[0033] In this embodiment, if Figure 2 As shown, an inflow tube 6 is fixedly installed at the bottom end of the insertion tube 3 inside the collecting bottle 2, and the bottom end part of the inflow tube 6 is conical. During use, the presence of the inflow tube 6 can prevent the gastric fluid inside the collecting bottle 2 from reflux under pressure, thereby ensuring that the equipment can operate stably and efficiently.

[0034] In this embodiment, if Figure 4As shown, a base 10 is fixedly mounted on the side of the top of the collecting bottle 2 away from the insertion tube 3, a top cover 11 is threadedly mounted on the outside of the base 10, a discharge port 12 is provided inside the base 10, and grooves are equidistantly provided outside the top cover 11. During use, the top cover 11 is rotated to detach from the outside of the base 10, exposing the base 10 itself, and then the gastric juice collected in the collecting bottle 2 can be quickly and completely poured out.

[0035] In this embodiment, if Figure 4 As shown, the top layer of the collecting bottle 2 is cylindrical, the bottom end is conical, and the outer surface of the collecting bottle 2 is symmetrically provided with scale lines for calculation. During use, the shape of the collecting bottle 2 itself can be used to concentrate the incoming gastric juice, and then the scale lines can be intuitively observed to preliminarily calculate the amount of gastric juice.

[0036] In this embodiment, if Figure 5 As shown, an exhaust port 7 is fixedly installed on the side of the top of the negative pressure bottle 1 away from the air supply pipe 4, and a sealing cover is installed on the top of the exhaust port 7. During use, the exhaust port 7 itself can be quickly opened and sealed to complete the control of the overall air pressure of the negative pressure bottle 1, which is convenient for quickly releasing the internal pressure of the negative pressure bottle 1.

[0037] In this embodiment, if Figure 5 As shown, a fixing block 8 is fixedly installed at the top of the negative pressure bottle 1 between the air supply pipe 4 and the exhaust port 7. A circular notch is provided inside the fixing block 8. During use, the fixing block 8 is installed to facilitate installation and positioning of the device body, making it easier to press the negative pressure bottle 1.

[0038] In this embodiment, if Figure 5 As shown, a stop clamp 9 is slidably installed on the outside of the gas pipe 4. The stop clamp 9 consists of an outer shell, a slide groove and a roller. During use, the roller can be slid and rotated, and then the slide groove can be used to squeeze and limit the caliber size inside the gas pipe 4.

[0039] In this embodiment, if Figure 4 As shown, the height of the outlet of the suction nozzle 5 exceeds the lowest position of the inflow tube 6, which can effectively prevent gastric fluid from entering the suction nozzle 5 and directly flowing into the negative pressure bottle 1 during use, making the collection of gastric fluid more accurate and facilitating the subsequent calculation of the gastric fluid volume.

[0040] In this embodiment, if Figure 3 As shown, the cannula 3 is composed of a rubber hose and a conical plug. The cannula 3 can be quickly moved and adjusted during use, and the conical plug can accurately absorb gastric juice without causing any impact on the patient himself, especially an infant.

[0041] In this embodiment, if Figure 1 As shown, the outer part of the negative pressure bottle 1 is spring-shaped as a whole and is made of plastic material as a whole. When the negative pressure bottle 1 is pressed during use, the negative pressure bottle 1 can automatically return to its original shape, and the purpose of pressure change is achieved by using the change of the internal air pressure of the negative pressure bottle 1 itself.

[0042] The working principle provided by the utility model is that during use, by pressing the negative pressure bottle 1, the change of the internal air pressure of the negative pressure bottle 1 and the cooperation of the air supply pipe 4 are used to change the internal pressure of the collecting bottle 2, and then the change of the internal pressure of the collecting bottle 2 is used to make the cannula 3 absorb the gastric juice from the stomach of the infant, and the gastric juice will be concentrated and stored in the collecting bottle 2. Because the shape and height of the suction nozzle 5 itself prevent the gastric juice from continuing to flow into the subsequent negative pressure bottle 1, the collection of the gastric juice is more stable and concentrated, and the subsequent pouring out and collection are also more convenient. Afterwards, the shape of the collecting bottle 2 itself can be used to concentrate the incoming gastric juice, and then the scale line can be intuitively observed to preliminarily calculate the amount of gastric juice. Finally, by rotating the top cover 11, the top cover 11 is separated from the outside of the base 10, and the base 10 itself is exposed. After that, the gastric juice collected in the collecting bottle 2 can be quickly and completely poured out, and the absorption, collection, calculation and discharge of the gastric juice can be quickly completed, making the working quality of the equipment itself more perfect.
