[0001] The utility model relates to the field of medical instruments, and more specifically to a sputum suction and nutrition integrated stomach tube. Background Art

[0002] A gastric tube is a clinical medical device that is inserted through the nostrils and reaches the stomach through the pharynx and esophagus. It can be used to extract gastric juice, inject liquid into the stomach, or provide food and nutrition to patients. Patients with gastric tube intubation often have a lot of saliva in their mouths. It is difficult for patients to swallow saliva to a certain extent, which can easily cause aspiration. Therefore, it is necessary to suck out oropharyngeal secretions in time to avoid aspiration leading to lung infection. However, suctioning sputum through the mouth and nose can easily cause damage to the oral and nasal mucosa and nasal mucosa.

[0003] In view of the problem in the prior art that oral and nasal mucosa and nasal mucosa are easily damaged when secretions from the oropharynx are sucked through the mouth and nose, there is an urgent need for a gastric tube that is convenient for suctioning sputum. Utility Model Content

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0014] Figure 1 It is a schematic diagram of the cross-sectional structure of the utility model of a sputum suction and nutrition integrated gastric tube. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] In the description of the present utility model, it should be noted that in the field of medical devices, the proximal end refers to the end closer to the operator, while the distal end refers to the end farther from the operator; the axial direction refers to the direction parallel to the line connecting the distal center and the proximal center of the medical device in the natural state. The above definitions are only for the convenience of expression and cannot be understood as limitations of the present invention.

[0017] like Figure 1As shown, in the first embodiment of the integrated sputum suction and nutrition gastric tube of the utility model, the gastric tube 10 includes a nutrition tube 11, an injection tube 12 fixedly arranged at the proximal end of the nutrition tube 11 and connected with the nutrition tube 11, a nutrition hole 13 arranged at the distal end of the nutrition tube 11 and connected with the nutrition tube 11, a sputum suction tube 14 sleeved outside the proximal end of the nutrition tube 11, a suction tube 15 fixedly connected and connected with the proximal end of the sputum suction tube 14, and a plurality of sputum suction holes 16 arranged on the sputum suction tube 14 and connected with the inner cavity of the sputum suction tube 14, a gap 17 for liquid circulation is provided between the nutrition tube 11 and the sputum suction tube 14, and the proximal and distal ends of the sputum suction tube 14 are both sealed with the nutrition tube 11.

[0018] When using the sputum suction and nutrition integrated stomach tube 10 of the utility model, the stomach tube 10 is inserted into the patient's stomach, and nutrient solution is injected into the nutrition tube 11 from the injection tube 12, and the nutrient solution finally enters the patient's stomach from the nutrition hole 13 to form nutrition delivery. During the use of the stomach tube, the suction tube 15 of the sputum suction tube 14 can be connected to the negative pressure sputum suction device (negative pressure machine), and oral secretions and sputum are sucked into the sputum suction tube 14 from the multiple sputum suction holes 16, and finally discharged from the suction tube 15.

[0019] Furthermore, in the present application, a plurality of sputum suction holes 16 are distributed in a spiral shape along the peripheral wall of the nutrition tube 11, so that the sputum suction tube 16 can have a spiral sputum suction structure along its own axis, so that sputum and other secretions can be more fully sucked, thereby improving the sputum suction efficiency. It is understandable that the sputum suction holes 16 can also be of other shapes and arranged in other ways, as long as it is convenient to suck sputum, and no specific limitation is made here.

[0020] Furthermore, in order to facilitate the injection of nutrient solution, the injection tube 12 is a conical cylindrical injection tube 12 , and the small-diameter end of the injection tube 12 is fixedly connected to the proximal end of the nutrient tube 11 .

[0021] Preferably, the sputum suction tube 14 is made of an elastic hose, and its two ends are sealed and respectively provided with a first through hole 18 and a second through hole 19. When the nutrition tube 11 passes through the first through hole 18 and the second through hole 19, an interference fit is formed, so that the nutrition tube 11 passes through in a sealed manner. That is, the end wall at the proximal end of the sputum suction tube 14 is provided with a first through hole 18 through which the nutrition tube 11 can pass in a sealed manner, and the end wall at the distal end of the sputum suction tube 14 is provided with a second through hole 19 through which the nutrition tube 11 can pass in a sealed manner. The sputum suction tube 14 can be interference-fitted with the outer peripheral wall of the nutrition tube 11 at both its proximal and distal ends, so that both ends of the sputum suction tube 14 achieve a good sealing effect to prevent sputum leakage. In order to prevent the sputum sucked into the sputum suction tube 14 from flowing out from both ends of the sputum suction tube 14, the apertures of the first through hole 18 and the second through hole 19 are smaller than or equal to the outer diameter of the nutrition tube 11, and the first through hole 18 and the nutrition tube 11 are interference fit, and the second through hole 19 and the nutrition tube 11 are interference fit. It is understandable that other sealing methods can also be used between the proximal end and the distal end of the sputum suction tube 14 and the nutrition tube 11, such as sealing with a sealing ring, etc., and no excessive restrictions are made here.

[0022] Furthermore, the suction tube 15 is fixedly mounted on the side wall of the proximal end of the sputum suction tube 14 , and a negative pressure joint 20 and a suction head 21 which are in communication with the suction tube 15 are disposed on the suction tube 15 .

[0023] During the sputum suction process, the negative pressure device is connected to the negative pressure connector 20 and communicated, and the sputum is sucked out by the negative pressure device and finally discharged from the suction head 21. The suction tube 15 and the feeding tube 11 are at a certain angle, so that the sucked secretions can enter the suction tube 15 under the action of gravity and be collected by a collection device such as a collection bag connected to the outer end of the suction tube 15.

[0024] Furthermore, a connecting hole 22 is provided on the nutrition tube 11 at a position corresponding to the sputum suction tube 14 , and the connecting hole 22 connects the inner cavity of the nutrition tube 11 and the gap 17 .

[0025] During the process of injecting the nutrient solution, part of the nutrient solution may flow from the connecting hole 22 into the sputum suction tube 14 to dilute the sputum, which is more conducive to the suction of the sputum.

[0026] Compared with the prior art, the utility model has the following beneficial effects: when using the sputum suction and nutrition integrated gastric tube of the utility model, the gastric tube is inserted into the patient's stomach, and the nutrient solution is injected into the nutrient tube from the injection tube, and the nutrient solution finally enters the patient's stomach from the nutrient hole to form nutrient delivery. In the process of delivering the nutrient solution, the suction tube of the sputum suction tube can be connected to the negative pressure sputum suction device (negative pressure machine), and oral secretions and sputum are sucked into the sputum suction tube from the spiral sputum suction hole, and finally discharged from the suction tube. Furthermore, in the present application, by setting the spiral sputum suction hole on the sputum suction tube, the sputum around the sputum suction tube can be fully sucked, the residue can be reduced, and the sputum suction efficiency can be improved.

[0027] In addition, in the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", "stacked" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
