Detailed ways

To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are a part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can be combined with the relevant description of the specification to explain the operation principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible embodiments and the advantages of the present invention. Components in the figures are not drawn to scale, and similar component symbols are often used to represent similar components.

The present utility model will now be further described with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 , this embodiment provides a gastric tube stethoscope, which includes a stethoscope body and an inflating device connected to the gastric tube. The stethoscope body includes a sound guide tube 10 , a sound guide frame 20 and an auscultation head 30 respectively located on both ends of the sound guide tube 10 . Since the sound guide tube 10 , the sound guide frame 20 and the auscultation head 30 are all in the prior art, their specific structures will not be described in detail, and those skilled in the art can directly purchase them from the market.

The inflating device includes a balloon 40 and a trachea 50, the balloon 40 is fixed on the back of the auscultation head 30 away from the auscultation surface, one end of the trachea 50 is communicated with the balloon 40, and the other end of the trachea 50 is a free end, which is used for connecting with the stomach. Tube connection. The fixation of the balloon 40 and the auscultation head 30 may be carried out by means of a clamp.

When using the gastric tube stethoscope, the operator first inserts the earplugs on the sound guide frame 20 into the ears, then connects the free end of the trachea 50 to the patient's gastric tube, and then sticks the auscultation surface of the auscultation head 30 to the patient's stomach. When the auscultation head is moved, the balloon 40 can be squeezed to inflate the gastric tube, and at the same time, whether there is a bubble sound in the stomach is used to determine whether the gastric tube is placed in the stomach. The gastric tube stethoscope is assembled on the stethoscope body, and the balloon 40 is fixed on the back of the auscultation head, so that the operator can perform the pumping operation while auscultating, and can realize one-handed operation. The gastric tube stethoscope has the advantages of simple structure, low cost and convenient operation.

In this embodiment, as shown in FIG. 1 , the free end of the trachea 50 is further provided with an elastic sleeve 51 , and the elastic sleeve 51 is made of an elastic material, such as rubber. The inner diameter of the elastic sleeve 51 is slightly smaller than the outer diameter of the trachea 50 and the stomach tube, so that both the trachea 50 and the stomach tube can be directly inserted into the elastic sleeve 51 for fixing, and the connection between the trachea 50 and the stomach tube can be directly realized, so that the Since the operator connects the trachea 50 and the gastric tube, the efficiency of the operation is improved.

In this embodiment, referring to FIG. 2 , the middle part of the trachea 50 also has a one-two-position three-way valve 52 , which divides the trachea 50 into a first trachea 501 and a second trachea 502 . One end is connected to the balloon 40, the other end is connected to the first connection port of the 3/2-way valve 52, one end of the second trachea 502 is connected to the second connection port of the 3/2-way valve 52, and the other end is connected to the free end of the gastric tube. The third connection port of the two-position three-way valve 52 is connected to one end of a conduit 60 , and the other end of the conduit 60 is connected to a negative pressure bag 61 . The two-position three-way valve 52 has a first state and a second state. In the first state, the first trachea 501 and the second trachea 502 communicate with each other, and the conduit 60 is in a non-conducting state; in the second state, the conduit 60 is connected to the The second air pipe 502 is in communication, and the first air pipe 501 is in a non-conducting state.

The three connection ports of the two-position three-way valve 52 are preferably arranged in a T-shape as shown in FIG. 2 , so that the operator can easily operate with one hand.

Because critically ill neurology patients are often required to perform gastric tube drainage when nasogastric feeding tube placement is used to assist feeding, that is, to extract gastric contents from the body. When gastric tube drainage is required, the two-position three-way valve 52 of the gastric tube stethoscope will be in a state where the trachea 50 and the gastric tube are closed in the direction and open in the direction of the catheter 60, and the gastric contents will be drained through the negative pressure bag 61 to prevent backflow. Flow aspiration. The gastric tube stethoscope can also perform gastric tube drainage while auscultating whether the gastric tube is correctly placed in the stomach, and the gastric tube drainage operation can also be operated by a single person, and the gastric tube stethoscope has the advantages of simple structure, low cost, and easy operation. Convenience advantage.

Although the present invention has been specifically shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that changes in form and detail may be made without departing from the spirit and scope of the present invention as defined by the appended claims. Various changes are made to the present utility model, which are all within the protection scope of the present utility model.
