Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a thyroid drainage tube. Background Art

[0002] Due to the rich blood supply and special location of the thyroid gland, continuous negative pressure drainage is essential after surgery. Placing a drainage tube can reduce blood and fluid accumulation in the surgical area, monitor bleeding, and prevent tracheal compression. However, if the drainage is improper, blood and fluid accumulation may occur at the mildest, and breathing difficulties and suffocation may occur in severe cases, which is not conducive to the patient's postoperative recovery.

[0003] At present, when using a thyroid drainage tube for drainage, a drainage ball is installed at the bottom of the drainage tube, and the drainage ball is kept in a negative pressure state. When the body fluid exceeds half of the ball, the negative pressure state of the drainage ball is released in time, and the drainage volume is recorded by comparing with the scale line of the ball, and the body fluid is dumped. After the body fluid is dumped, the negative pressure state of the drainage ball should be maintained to prevent the liquid inside the drainage ball from flowing back into the patient's body again, causing infection and other symptoms; however, the existing drainage tubes generally do not have a backflow prevention function, and there is a risk of retrograde body fluid during use, leading to wound infection. In addition, the thyroid drainage tubes used clinically are generally single tubes, which are used to drain the surgical operation site of the thyroid bed, which is not convenient for drainage of the surgical operation site of the lateral neck area at the same time.

[0004] In view of this, the shortcomings of the existing structure are studied and improved, and a new type of thyroid drainage tube is proposed. Utility Model Content

[0005] In view of the above problems, the purpose of the utility model is to provide a thyroid drainage tube.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a thyroid drainage tube, comprising a connecting mechanism, a drainage mechanism is installed on the top of the connecting mechanism, the connecting mechanism comprises an outer shell, the inner surface of the outer shell is provided with two guide channels, the two guide channels are combined to form a "Y"-shaped or "U"-shaped tubular guide channel, the bottom of the outer shell is provided with a discharge channel, the discharge channel is connected to the guide channel, the inner wall of the guide channel is fixedly connected with an arc-shaped support sheet, the drainage mechanism comprises a drainage tube, a limiting channel is provided at the bottom of the drainage tube, an anti-backflow ball is provided inside the limiting channel, and the anti-backflow ball is located above the arc-shaped support sheet.

[0007] Furthermore, the number of the outer shells is two, and the inner surfaces of the two outer shells are fixedly connected by adhesive.

[0008] Furthermore, there are two drainage tubes, which are respectively located at the left and right ends of the diversion channel.

[0009] Furthermore, the cross-sectional structure of the limiting channel is an isosceles trapezoidal structure, the diameter of the anti-backflow ball is larger than the top diameter of the limiting channel, and the diameter of the anti-backflow ball is smaller than the bottom diameter of the limiting channel.

[0010] Furthermore, the inner walls of the guide channels of the two shells are fixedly connected with arc-shaped support sheets, and a gap is provided between two opposing arc-shaped support sheets.

[0011] Furthermore, a discharge pipe is fixedly connected to the inside of the discharge channel.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting up a connecting mechanism and a drainage mechanism, the backflow prevention ball will fall onto the arc-shaped support sheet under the action of gravity when in use, and the drainage fluid discharged from the drainage tube will flow from the gap between the two arc-shaped support sheets to the discharge tube, and finally enter the drainage ball from the discharge tube. When there is too much drainage fluid and it is not cleaned up in time, the drainage fluid will rise along the diversion channel. At this time, the backflow prevention ball will float on the drainage fluid and move upward with the rise of the drainage fluid, and finally get stuck above the limiting channel to prevent the drainage fluid from continuing to move upward, thereby preventing the drainage fluid from retrograde into the patient's body and causing infection.

[0014] By setting up a thyroid drainage tube with a "Y"-shaped or "U"-shaped structure, one drainage tube can drain the thyroid bed, and the other drainage tube can drain the exudate from the surgical operation site in the lateral neck area, thereby effectively avoiding postoperative incision complications such as postoperative suffocation and incision infection.

[0021] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0022] Reference Figure 1-4 A thyroid drainage tube of the present embodiment includes a connecting mechanism 1, and a drainage mechanism 2 is installed on the top of the connecting mechanism 1, which can drain the exudate of the thyroid bed and the surgical operation site of the lateral neck area at the same time. The connecting mechanism 1 includes a shell 101, and the number of shells 101 is two. The inner surfaces of the two shells 101 are fixedly connected by adhesive, which can stably install the arc-shaped support sheet 104, the drainage tube 201, and the anti-backflow ball 203, and can also simplify the processing difficulty of the shell 101. Two diversion channels 102 are opened on the inner surface of the shell 101. The two diversion channels 102 in the present embodiment are combined to form a "U"-shaped tubular channel, which is convenient for the drainage of body fluids.

[0023] The bottom of the shell 101 is provided with a discharge channel 103, which is connected to the guide channel 102. The inner wall of the guide channel 102 is fixedly connected with an arc-shaped support sheet 104. The inner wall of the guide channel 102 of each shell 101 is connected with an arc-shaped support sheet 104, and a gap is provided between two relatively arc-shaped support sheets 104; the drainage mechanism 2 includes a drainage tube 201, and a limited position channel 202 is provided at the bottom of the drainage tube 201. An anti-backflow ball 203 is provided inside the limited position channel 202. The cross-sectional structure of the limited position channel 202 is an isosceles trapezoidal structure, and the anti-backflow ball 203 is provided inside the limited position channel 202. The diameter of the flow ball 203 is larger than the top diameter of the limiting channel 202, and the diameter of the anti-backflow ball 203 is smaller than the bottom diameter of the limiting channel 202, so that the anti-backflow ball 203 can move up and down inside the limiting channel 202. When the anti-backflow ball 203 reaches the top of the limiting channel 202, the top of the limiting channel 202 can be sealed to prevent the body fluid from flowing back; when the anti-backflow ball 203 is located above the arc-shaped support plate 104, the arc-shaped support plate 104 supports the anti-backflow ball 203, and the body fluid can be discharged from the gap between the two arc-shaped support plates 104.

[0024] There are two drainage tubes 201, which are respectively located at the left and right ends of the diversion channel 102, so that the thyroid drainage tube presents a "U"-shaped structure as a whole. One drainage tube 201 can drain the thyroid bed, and the other drainage tube 201 can drain the exudate from the surgical operation site in the lateral neck area; the interior of the discharge channel 103 is fixedly connected with a discharge tube 3, and a drainage ball is installed at the bottom of the discharge tube 3. When the drainage ball is in a negative pressure state, the body fluid can be drained to avoid blood accumulation, fluid accumulation, difficulty breathing and other conditions after surgery.

[0025] Working principle: When in use, the anti-backflow ball 203 will fall onto the arc-shaped support piece 104 under the action of gravity, and the drainage fluid discharged from the drainage tube 201 will be discharged from the gap between the two arc-shaped support pieces 104, reach the discharge tube 3, and finally enter the drainage ball from the discharge tube 3; when there is too much drainage fluid and it is not cleaned up in time, the drainage fluid will rise along the diversion channel 102. At this time, the anti-backflow ball 203 will float on the drainage fluid and move up with the rise of the drainage fluid, and finally it will be stuck above the limiting channel 202 to prevent the drainage fluid from continuing to rise, thereby preventing body fluid from retrograde into the patient's body and causing infection.
