Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a fixed drainage device for postoperative care of the thyroid gland and its usage method. Background Technique

[0002] The thyroid gland is located in a closed space of the deep cervical fascia, and the tissue blood circulation is very rich. For thyroid diseases, the main surgical method is open surgery, with a relatively large surgical wound surface. After the operation, there is a lot of bleeding and exudation from the wound surface, and the neck tissue is relatively loose. Pressing and bandaging will affect breathing. If no drainage is placed routinely after the operation, the continuous accumulation of exudates will not only affect the healing of the incision, but may also affect the patient's breathing and even endanger life. Research shows that once the accumulated blood and fluid in the surgical area after thyroid surgery exceed 50 mL, there is a risk of asphyxia. To reduce the occurrence of asphyxia, drainage needs to be placed after the operation.

[0003] When draining after thyroid surgery currently, the shaking of the patient's neck easily causes the detachment of the drainage tube, affecting the drainage effect and the recovery of the wound, and it is not convenient to maintain continuous drainage when replacing the drainage bag; therefore, it does not meet the existing requirements, and for this reason, we propose a fixed drainage device for postoperative care of the thyroid gland and its usage method.

[0015] A usage method of a fixed drainage device for postoperative care of the thyroid gland includes the following steps:

[0016] S1: Put the elastic suspension strip on the patient's neck and adhere it to the hospital gown through the magic tape provided on the surface of the adhesive cloth strip, so as to facilitate fixing the elastic suspension strip relative to the neck. Then, both ends of the elastic suspension strip are connected to the two transmission strips through pin shafts. Rotate the transmission screw, so that the transmission screw drives both ends of the elastic suspension strip to slide in opposite or the same directions through the two transmission strips, so as to facilitate the use for necks of different sizes, and the neck suspension mechanism can keep the tightness monitoring mechanism and the diversion and temporary storage mechanism in a suspended state;

[0017] S2: Connect the power supply. Insert the bottom end of the wound drainage tube and two first drainage tubes through a three-way pipe, and connect both ends of the second drainage tube to the first drainage tube and the storage bag respectively. Thus, the wound drainage tube is connected to the two storage bags through the three-way pipe, two first drainage tubes and the second drainage tube. Then, position and install the three-way pipe, the first drainage tube and the second drainage tube. Specifically, the bottom end of the connecting strip penetrates through the positioning block and is inserted into the inner side of the placement block, so that the positioning block and the placement block are clamped and installed through the connecting strip, and the three-way pipe can axially slide relative to the positioning block and the placement block. The first drainage tube penetrates through a plurality of elastic restraint strips and is arranged in an S shape. The middle part of the second drainage tube is inserted between the extrusion gear and the elastic support seat;

[0018] S3: When draining the patient after surgery, insert the upper end of the wound drainage tube into the wound, start the motor. The motor drives the extrusion gear to rotate under the support of the support plate and extrude the middle part of the second drainage tube. Then, the middle part of the second drainage tube can continuously be in a negative pressure state under the elastic support of the elastic support seat during the rotation and extrusion by the extrusion gear. At this time, the second drainage tube drains and extracts the wound effusion to the inner side of the storage bag through the first drainage tube, the three-way pipe and the wound drainage tube. By measuring the rotation parameters of the extrusion gear, the amount of effusion in the storage bag can be monitored;

[0019] S4: The two storage bags can meet the full drainage of the patient and are convenient for replacing the storage bags during continuous drainage. When the patient's body shakes during drainage, the wound drainage tube drives the two second drainage tubes to slide inside the plurality of elastic restraint strips through the three-way pipe under the drive of the neck. The transparent protective cover is sleeved outside the installation frame to protect and isolate the plurality of elastic connection units;

[0020] S5: At this time, both ends of the elastic restraint strip are clamped and installed with the block, and the connecting column is fixedly connected to the block and connected to the guide sleeve through the support spring. Under the elastic support of the support spring, the connecting column can elastically pull the bent part of the first drainage tube through the block and the elastic restraint strip.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The present invention can keep the tightness monitoring mechanism and the diversion and temporary storage mechanism in a suspended state through the neck suspension mechanism. The positioning pressing block and the placing block are clamped and installed through the connecting card strips, keeping the three-way pipe axially slidable relative to the positioning pressing block and the placing block. The first diversion pipe penetrates through a plurality of elastic binding strips and is arranged in an S shape. The wound drainage pipe drives the two second diversion pipes to slide inside the plurality of elastic binding strips synchronously through the three-way pipe under the drive of the neck. Under the elastic support of the support spring, the connecting column can elastically pull the bent part of the first diversion pipe through the clamping block and the elastic binding strips, so as to facilitate the first diversion pipe to have a movement amount when the patient's neck shakes, and keep the stability of the drainage of the first diversion pipe and the stability of the connection between the wound drainage pipe and the neck wound.

[0023] 2. The present invention drives the extrusion gear to rotate through the motor and extrudes the middle part of the second diversion pipe. Then, the middle part of the second diversion pipe can continuously be in a negative pressure state during the rotation and extrusion of the extrusion gear under the elastic support of the elastic support seat. The second diversion pipe diverts and extracts the wound effusion to the inside of the storage bag for storage through the first diversion pipe, the three-way pipe and the wound drainage pipe. By measuring the rotation parameters of the extrusion gear, the amount of effusion inside the storage bag can be monitored. The two storage bags can meet the sufficient drainage of the patient and facilitate the replacement of the storage bag during continuous drainage. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] A using method of a fixed drainage device for postoperative care of the thyroid gland includes the following steps:

[0043] S1: The elastic suspension strip 101 is sleeved on the patient's neck and adhered to the hospital gown through the magic tape provided on the surface of the adhesion cloth strip 102, thereby facilitating the fixation of the elastic suspension strip 101 relative to the neck. Then, both ends of the elastic suspension strip 101 and the two transmission strips 103 are connected through pin shafts. The transmission screw 104 is rotated, so that the transmission screw 104 drives both ends of the elastic suspension strip 101 to slide in opposite or the same directions through the two transmission strips 103, thereby facilitating the use for necks of different sizes.
