Problems solved by technology

However, if the postoperative drainage device is not smooth, such as tissue and blood clots blocking the drainage tube, it will also cause blood accumulation and fluid accumulation to press the trachea, and will also suffocate the patient; The main purpose of the device is: to drain the blood and exudate from the wound, reduce its pressure on the trachea and surrounding tissues and the impact on incision healing; it can detect active bleeding in time, so that hemostasis and first aid measures can be taken in time; For patients with side lymph node dissection, drainage must be placed after surgery; for retrosternal goiter and giant thyroid cyst, drainage is required; for patients with unclear anatomical layers, more bleeding, incomplete hemostasis, and longer operation time, drainage is required. placement drainage
[0003] Therefore, due to the above-mentioned particularity of drainage after thyroid surgery, the requirements for drainage devices after thyroid surgery are different from those of conventional drainage devices. Suffocation is relatively dangerous because there are higher requirements for preventing the drainage tube from bending and blocking; secondly, in the process of negative pressure drainage, the control and adjustment of negative pressure is also a major factor to ensure smooth drainage. Large, inconvenient to use, or a one-time negative pressure drainage ball, unable to adjust and monitor the negative pressure, which is inconvenient for the drainage after thyroid surgery; moreover, the drainage tube used in the drainage process after thyroid surgery also needs to be based on the actual situation. However, the existing drainage device is integrated, which is inconvenient to use; therefore, a special postoperative negative pressure drainage device for thyroid surgery is needed

Embodiment 1

[0054] Such as Figure 1-6 shown

[0055] A negative pressure drainage device after thyroid surgery, comprising a negative pressure drainage part 1, a drainage tube part 2 and an outer sheath 3, the negative pressure drainage part 1 is connected with the drainage tube part 2, and the negative pressure drainage part 1 monitors and adjusts the negative pressure Drainage is carried out through the drainage tube part 2, and the outer sheath 3 is sheathed on the periphery of the negative pressure drainage part 1;

[0056] When in use, select the appropriate drainage tube part 2 to connect with the negative pressure drainage part 1. The main body of the negative pressure drainage part 1 includes a base 6 at the bottom, a top seat 4 at the upper end, and a telescopic tube installed between the base 6 and the top seat 4. The bellows 5, the outer edges of the base 6 and the top seat 4 are connected by an adjustment rod 7 uniformly installed in the circumferential direction, and the di...

Embodiment 2

[0070] Such as Figure 1-6 shown

[0071] Negative pressure drainage device after thyroid surgery, including negative pressure drainage part 1, drainage tube part 2 and outer sheath 3, negative pressure drainage part 1 is connected with drainage tube part 2, and negative pressure drainage part 1 monitors and adjusts the negative pressure through drainage The pipe part 2 is used for drainage, and the outer sheath 3 is sheathed around the end of the negative pressure drainage part 1;

[0072] The adjusting rod 7 includes an internally threaded sleeve 701 installed at both ends on the base 6 and the top seat 4, and a positive and negative threaded screw rod 702 connecting the two internally threaded sleeves 701. The adjustment seat 703 is used to adjust the length of the adjustment rod 7 by rotating the adjustment seat 703;

[0073] The adjusting rod 7 adjusts the distance between the base 6 and the top seat 4 and then adjusts the inner cavity volume of the telescopic bellows 5...

Embodiment 3

[0080] Application of a negative pressure drainage device after thyroid surgery in negative pressure drainage after thyroid surgery.

[0081] Based on Embodiment 1 and Embodiment 2, when the present invention is applied to negative pressure drainage after thyroid surgery, the operation steps of Embodiment 1 are followed, and it can also be applied to other drainages that require controlled negative pressure.

[0082] The negative pressure drainage device after thyroid surgery of the present invention includes a negative pressure drainage part, a drainage tube part and an outer sheath, the negative pressure drainage part is connected with the drainage tube part, and the negative pressure drainage part monitors and adjusts the negative pressure through the drainage tube part. Drainage, the end of the negative pressure drainage part is covered with an outer sheath; after selecting a suitable drainage tube part of the drainage end to seal and stably connect with the negative pressu...

Abstract

The invention discloses a thyroid-surgery postoperative negative pressure drainage device, and relates to the technical field of postoperative negative pressure drainage. The thyroid-surgery postoperative negative pressure drainage device comprises a negative pressure drainage part, a drainage tube part and an outer protection sleeve, wherein the negative pressure drainage part is in joint with the drainage tube part, the negative pressure drainage part monitors and adjusts negative pressure, drainage is conducted through the drainage tube part, and the outer protection sleeve sleeves the endof the negative pressure drainage part. According to the thyroid-surgery postoperative negative pressure drainage device, monitoring and negative pressure adjustment can be conducted through a drainage device body, it is avoided that a drainage tube is bent and blocked, and it is guaranteed that drainage is smooth; the thyroid-surgery postoperative negative pressure drainage device is reasonable in structural design, high in controllability and suitable for application and popularization of thyroid postoperative negative pressure drainage.

Description

technical field [0001] The invention relates to the technical field of postoperative negative pressure drainage, in particular to a postoperative negative pressure drainage device for thyroid surgery. Background technique [0002] The thyroid gland is located in a closed gap in the deep fascia of the neck, and its blood supply is very rich. Thyroid disease mainly adopts open surgery, the surgical wound is large, the postoperative wound oozes more blood and exudate, and the neck tissue is loose, and the pressure bandage will affect breathing. The continuous accumulation of debris will not only affect the healing of the incision, but also may affect the patient's breathing, and even endanger life. Studies have shown that there is a risk of suffocation once the hemorrhage and fluid accumulation in the surgical area exceeds 50mL after thyroidectomy. In order to reduce the occurrence of suffocation, routine postoperative drainage is recommended. However, if the postoperative dr...
