Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The embodiment of the utility model provides a nasogastric tube or gastrostomy tube tee junction valve, as shown in figure 1, include: the three-way valve 2 is rotatably connected to the three-way pipe 1 and is used for controlling the on-off of the three-way pipe 1; the three-way pipe 1 comprises a first connector 11, a second connector 12 and a third connector 13, wherein the first connector 11 is detachably connected with a nutrient solution injector, the second connector 12 is detachably connected with a nasogastric tube or a gastrostomy tube, and the third connector 13 is detachably connected with a common injector. It will be appreciated that in order to ensure a tight connection between the first port 11, the second port 12 and the third port 13 and the corresponding external device, corresponding sealing parts should be provided at the interface locations to avoid leakage during the liquid injection process. Use the utility model discloses during the infusion of carrying out the nutrient solution, when accomplishing the injection of a syringe nutrient solution, only need to transfer the three-way valve 2 that corresponds the position to the closed condition, need not to carry out nasogastric tube or stomach fistulization pipe's tail end and buckle, just can carry out the suction of a new pipe nutrient solution. Therefore, the hands of a doctor are liberated, the nutrient solution can be pumped by the hands, and the problem that the tail end of the pipeline must be bent to avoid the backflow of the nutrient solution is solved. Therefore, the working efficiency of nursing personnel can be greatly improved, the nasogastric tube and the stomach fistulization tube can be protected, and the service life of the nasogastric tube and the stomach fistulization tube is prolonged.
In one aspect of the embodiment of the present invention, the three-way valve 2 includes a first valve port, a second valve port and a third valve port corresponding to the three-way pipe 1. When the interface is communicated with any valve port in the using process, the interface is in a communicated state. For example, when the nutrient solution is infused, the three-way valve 2 is adjusted to enable the first connector 11 and the second connector 12 to be communicated, after the infusion of one tube of nutrient solution is completed, the three-way valve 2 is adjusted to enable the first connector 11 and the second connector 12 to be disconnected, a new tube of nutrient solution is sucked, after the suction is completed, the first connector 11 and the second connector 12 are connected, the steps are repeated until the infusion of all the nutrient solution is completed, the process does not need to bend the gastrostomy tube, and the operation is convenient. Similarly, when the ordinary medicine needs to be infused, the infusion operation can be completed after the second interface 12 and the third interface 13 are connected by adjusting the three-way valve 2. In addition, in order to keep the inside of the mouthpiece clean and free from contamination, a closing cap may be detachably fitted to the outside of the first mouthpiece 11, the second mouthpiece 12, and the third mouthpiece 13. The sealing cap is sleeved when not in use and taken down when in use.
Preferably, four groups of clamping grooves and protrusions are uniformly arranged between the three-way pipe 1 and the three-way valve 2, the clamping grooves are detachably connected in the protrusions, the effect of positioning the butt joint position of the three-way pipe 1 and the three-way valve 2 is achieved, accurate butt joint between the interface and the valve port is guaranteed, and smooth and easy connection of the connecting passages is guaranteed.
Preferably, the three-way valve 2 further includes a first valve rod 21, a second valve rod 22 and a third valve rod 23 respectively corresponding to the first valve port, the second valve port and the third valve port, and the first valve rod 21, the second valve rod 22 and the third valve rod 23 are configured to indicate positions of the first valve port, the second valve port and the third valve port, so as to facilitate operation and control of a user.
In an aspect of the embodiment of the present invention, the first interface 11 is soft, can adopt polyurethane or silica gel material, is the same material with clinical nasogastric tube, and the second interface 12 and the third interface 13 channel are hard, and are the same material with syringe for injection, generally polymer polypropylene material, so as to perfectly match with the existing clinical products.
In an aspect of the embodiment of the present invention, the aperture of the first interface 11 is larger than the aperture of the outlet of the nutrient solution injector. Preferably, the aperture of said second port 12 is smaller than the aperture of the entrance of a nasogastric or gastrostomic tube. Preferably, the aperture of the third interface 13 is larger than the aperture of the outlet of a common syringe. Because the first interface 11 and the third interface 13 are input ports for receiving external liquid, and the openings of the input ports are larger than the outlets of liquid source equipment, the liquid leakage can be prevented, and the air tightness can be kept; based on the same principle, the second interface 12 is an output port for outputting liquid, and the opening of the second interface is smaller than the inlet of the liquid receiving device, so that the liquid is prevented from leaking outwards, and the air tightness is kept.
Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the scope of the present invention.
