Description

Technical Field

[0001] This utility model generally relates to the field of medical device technology, and more specifically, to a postoperative minimally invasive subcutaneous continuous drainage device. Background Technology

[0002] Subcutaneous infection and fluid accumulation are common after various superficial surgeries, including those for the thyroid gland, parotid gland, submandibular gland, fibroma, and lipoma. Adequate drainage is a prerequisite for treatment.

[0003] Currently, the traditional clinical drainage method involves puncture and catheter placement through an open surgical incision. This method results in a large wound, slow postoperative wound healing, and leaves obvious scars. Furthermore, pus or blood clots in the wound can easily block the drainage tube, interrupting drainage and affecting its effectiveness. Alternatively, ultrasound-guided puncture followed by multiple aspirations with a syringe can be performed. This method prolongs the recovery period, requires patients to endure the pain of repeated needle punctures and aspirations, and increases medical costs.

[0004] Therefore, there is an urgent need for a minimally invasive, continuous subcutaneous drainage device after surgery to solve the above-mentioned clinical problems. Utility Model Content

[0005] This application provides a minimally invasive subcutaneous continuous drainage device for postoperative treatment to solve the above-mentioned technical problems.

[0006] This application provides a postoperative minimally invasive subcutaneous continuous drainage device, comprising: a puncture needle, a drainage sheath, a three-way valve, a drainage tube, and a negative pressure drainage bottle. The three-way valve includes a first port, a second port, and a third port. The first port and the second port are coaxially arranged. The drainage sheath is connected to the first port. The puncture needle is inserted through the second port and exits through the drainage sheath. The negative pressure drainage bottle is connected to the third port through the drainage tube.

[0007] According to some embodiments of this utility model, an airbag is provided on the drainage tube.

[0008] According to some embodiments of the present invention, the tail of the puncture needle is provided with a handle.

[0009] According to some embodiments of this utility model, the drainage sheath is tapered at the end near the three-way valve.

[0010] According to some embodiments of this utility model, a fixing plate is provided at one end of the drainage sheath near the three-way valve.

[0011] According to some embodiments of this utility model, the drainage sheath is provided with multiple drainage holes on the side wall of the end away from the three-way valve.

[0012] According to some embodiments of the present invention, the second port is detachably provided with a heparin cap.

[0013] As can be seen from the above technical solution, the advantages and positive effects of the postoperative minimally invasive subcutaneous continuous drainage device of this utility model are as follows: The postoperative minimally invasive subcutaneous continuous drainage device of this application has the characteristics of small trauma, fast recovery, and no need for re-suture. The drainage sheath is inserted into the wound site through a puncture needle piercing the epidermis. The puncture needle has good puncture ability and is easy to operate. After reaching the wound site, the puncture needle is withdrawn from the second port. Because the puncture needle fills the drainage sheath during puncture, tissue debris can be avoided from clogging the drainage sheath. Removing the puncture needle and leaving the drainage sheath allows the drainage sheath to establish a good aspiration channel. At the same time, the three-way valve is switched so that pus and blood can directly enter the negative pressure drainage bottle from the third port along the drainage tube, avoiding leakage of drainage fluid caused by cumbersome disassembly and assembly. After using the postoperative minimally invasive subcutaneous continuous drainage device, patients avoid the pain caused by multiple needle punctures and aspirations, reducing time costs and the occupation of medical resources, and making clinical operation simpler.

[0027] like Figure 1 As shown in the embodiment, a postoperative minimally invasive subcutaneous continuous drainage device includes: a puncture needle 1, a drainage sheath 2, a three-way valve 3, a drainage tube 4, and a negative pressure drainage bottle 5. The three-way valve 3 includes a first port, a second port, and a third port. The first port and the second port are coaxially arranged. The drainage sheath 2 is connected to the first port. The puncture needle 1 is inserted through the second port and exits through the drainage sheath 2. The negative pressure drainage bottle 5 is connected to the third port through the drainage tube 4. This application uses a puncture needle 1 to puncture the epidermis, allowing the drainage sheath 2 to enter the wound site inside the body. The puncture needle 1 has good puncture ability and is easy to operate. After reaching the wound site, the puncture needle 1 is withdrawn from the second port. Since the puncture needle 1 fills the drainage sheath 2 during puncture, it can prevent tissue debris from blocking the drainage sheath 2. After withdrawing the puncture needle 1 and leaving the drainage sheath 2, the drainage sheath 2 can establish a good aspiration channel. At the same time, the three-way valve 3 is switched so that pus and blood can directly enter the negative pressure drainage bottle 5 from the third port along the drainage tube 4, avoiding leakage of drainage fluid caused by cumbersome disassembly and assembly.

[0028] like Figure 1 As shown, in some embodiments of this utility model, an airbag 6 is provided on the drainage tube 4. The airbag 6 is made of transparent rubber, which facilitates observation of the drainage situation and timely adjustment of the drainage flow rate. If a fibrous blockage is encountered, the airbag 6 can also be squeezed to clear the blockage.

[0029] like Figure 1 As shown, in some embodiments of this utility model, the puncture needle 1 is provided with a handle 7 at its tail. The handle 7 at the tail of the puncture needle 1 facilitates hand operation by medical personnel, makes it easier to apply force, and makes the puncture process easier.

[0030] like Figure 1 As shown, in some embodiments of this utility model, the drainage sheath 2 is tapered at the end near the three-way valve 3. The tapered shape at one end of the three-way valve 3 helps to strengthen the structure and prevent bending during use.

[0031] like Figure 1 As shown, in some embodiments of this utility model, a fixing piece 8 is provided at the end of the drainage sheath 2 near the three-way valve 3. When it is necessary to fix the drainage sheath 2, the fixing piece 8 serves as a fixing anchor point, and can be fixed to the patient's skin surface with medical tape to achieve fixation.

[0032] like Figure 2 As shown, in some embodiments of this utility model, a plurality of drainage holes 9 are provided on the side wall of the end of the drainage sheath 2 away from the three-way valve 3. The drainage holes 9 of uniform size are distributed on the side wall of the end of the drainage sheath 2 away from the three-way valve 3. The drainage holes 9 are alternately staggered, which increases the number of drainage holes 9 and facilitates the efficient drainage of pus and blood, reducing the risk of blockage.

[0033] like Figure 3 As shown, in some embodiments of this utility model, the second port is detachably equipped with a heparin cap 10. After the puncture needle 1 is withdrawn, the heparin cap 10 is installed on the second port, which can ensure that the port is not contaminated, and can also be used for drug administration and other operations through the heparin cap 10.
