Description

Technical Field

[0001] The utility model relates to the field of auxiliary rehabilitation equipment after pancreatic surgery, in particular to a double-tube positioning device for drainage and flushing after pancreatic surgery. Background Art

[0002] Flushing and drainage tubes after pancreatic surgery are an important part of postoperative care and are primarily used to monitor and manage postoperative complications such as infection, necrosis, and bleeding.

[0003] The flushing tube is mainly used to remove necrotic tissue and purulent fluid in the pancreas to prevent the formation of pancreatic bed abscesses and pseudocysts. For example, after surgery for severe acute pancreatitis, it is a common practice to use saline plus gentamicin for pancreatic bed lavage and drainage.

[0004] The drainage tube is used to drain fluid and gas from the abdominal cavity after surgery and to monitor for bleeding, pancreatic fistula or intestinal fistula, etc.

[0005] After surgery, the drainage tube and the flushing tube are separated from each other, and are randomly placed on the side of the patient's body. This not only makes it easy for the patient's body to press and cause the hose to be blocked, but also requires medical staff to find and distinguish the separated drainage tube and flushing tube before handling. This not only increases the processing time, but also has the risk of choosing the wrong tube. Utility Model Content

[0030] Please refer to Figure 1 and Figure 2 As shown in, a double-tube positioning device for postoperative drainage and irrigation of the pancreas includes:

[0031] The adhesive soft tape 1 is used to fit with the skin and is distributed with ventilation holes 2.

[0032] The positioning mechanism 3 is configured with adjacent and parallel first positioning channels 4 and second positioning channels 5.

[0033] The connection mechanism 6 is fixedly arranged on the top surface of the adhesive soft tape 1. The connection mechanism 6 covers part of the ventilation holes 2, and the thickness of the connection mechanism 6 is greater than the thickness of the adhesive soft tape 1. The positioning mechanism 3 is fixedly installed on the surface of the connection mechanism 6 opposite to the adhesive soft tape 1.

[0034] In this way, the adhesive soft adhesive tape 1 is attached to the front of the patient in a supine position, and then the drainage tube and the irrigation tube are respectively clamped and installed in the first positioning channel 4 and the second positioning channel, so that the drainage tube and the irrigation tube are fixed by the first positioning channel 4 and the second positioning channel 5 respectively. After the adhesive soft adhesive tape 1 is adhesively positioned with the patient's skin, the drainage tube and the irrigation tube can be positioned under the action of the first positioning channel 4 and the second positioning channel 5, ensuring that the drainage tube and the irrigation tube always remain relatively static with respect to the patient's body, avoiding large-scale shaking of the drainage tube and the irrigation tube when the patient's body moves, and reducing the risk of the drainage tube and the irrigation tube being compressed by the patient's body. Moreover, the relative positions of the irrigation tube and the drainage tube can be fixed, enabling medical staff to quickly distinguish between the drainage tube and the irrigation tube when maintaining and operating on them.

[0035] Furthermore, in order to reduce the situation where the positioning mechanism 3 is relatively hard while the adhesive soft adhesive tape 1 is relatively soft, and the adhesive soft adhesive tape 1 detaches from the positioning mechanism 3 after being arc-curved when in contact with the patient's skin, the positioning mechanism 3 is made of polytetrafluoroethylene material, the connecting mechanism 6 is made of foam material, and the toughness of the connecting mechanism 6 is between the toughness of the adhesive soft adhesive tape 1 and the toughness of the positioning mechanism 3.

[0036] In this way, making the positioning mechanism 3 of polytetrafluoroethylene can provide a good fixing effect for the positioning of the drainage tube and the irrigation tube by virtue of its mechanical properties. Using the connecting mechanism 6 made of foam material, since the foam has certain plasticity and supportability, at the connection between the connecting mechanism 6 and the adhesive soft adhesive tape 1, the connecting mechanism 6 can bend following the arc deformation of the adhesive soft adhesive tape 1, thereby reducing the pulling force generated by the bending of the adhesive soft adhesive tape 1 between the connecting mechanism 6 and the adhesive soft adhesive tape 1. Similarly, for the connection surface between the connecting mechanism 6 and the positioning mechanism 3, since the top surface of the connecting mechanism 6 is not pulled by the adhesive soft adhesive tape 1, the connection surface between the positioning mechanism 3 and the connecting mechanism 6 can be kept fixed, effectively avoiding the detachment of the connection surface between the connecting structure and the positioning mechanism 3 caused by the deformation of the connecting mechanism 6.

[0037] Further, the positioning mechanism 3 includes a receiving block 7 mounted on the top surface of the connection mechanism 6. The top surface of the receiving block 7 is provided with a first arc-shaped groove 41 and a second arc-shaped groove 51. Both the first arc-shaped groove 41 and the second arc-shaped groove 51 are arc surface structures with a central angle greater than 180°. The positioning mechanism 3 further includes a pressing block 8. One side of the pressing block 8 facing the receiving block 7 is provided with a third arc-shaped groove 42 and a fourth arc-shaped groove 52. The pressing block 8 is in abutting connection with the receiving block 7. The first arc-shaped groove 41 and the third arc-shaped groove 42 are spliced to form the complete cylindrical first positioning channel 4, and the second arc-shaped groove 51 and the fourth arc-shaped groove 52 are spliced to form the complete cylindrical second positioning channel 5. A fixing mechanism is provided on the side surface of the pressing block 8, and the fixing mechanism is detachably connected to the top surface of the connection mechanism 6.

[0038] In this way, the first positioning channel 4 and the second positioning channel 5 are set as open structures formed by splicing the first arc-shaped groove 41, the second arc-shaped groove 51, the third arc-shaped groove 42 and the fourth arc-shaped groove 52, which can facilitate the loading of the drainage tube and the irrigation tube. And by using the arc surface structure with a central angle greater than 180°, after the drainage tube and the irrigation tube are loaded, the drainage tube and the irrigation tube can be clamped to prevent them from detaching from the first arc-shaped groove 41 or the second arc-shaped groove 51.

[0039] Further, in order to facilitate the replacement of different bearing blocks 72, so as to be able to select the first positioning channel 4 and the second positioning channel 5 with different inner diameters according to actual needs, the receiving block 7 includes a mounting seat 71 fixedly connected to the connection mechanism 6. The top surface of the mounting seat 71 is provided with a bearing block 72 through a snap structure. The first arc-shaped groove 41 and the second arc-shaped groove 51 are formed on the top surface of the bearing block 72.

[0040] Further, in order to reduce the sliding of the drainage tube and the irrigation tube in the first positioning channel 4 or the second positioning channel 5, rubber strips 9 are coaxially provided on the inner walls of the first arc-shaped groove 41, the second arc-shaped groove 51, the third arc-shaped groove 42 and the fourth arc-shaped groove 52.

[0041] Furthermore, the fixing mechanism includes a pair of fixing blocks 10 respectively fixedly connected to the side surface of the pressing block 8. The top surface of the connection mechanism 6 is provided with a circular fuzzy surface, and the bottom surface of the fixing block 10 is provided with a barbed surface. The fixing block 10 is adhesively and detachably connected to the connection mechanism 6. The fixing block 10 is made of foam material. After the fixing block 10 is adhered to the connection mechanism 6, the side wall of the fixing block 10 is fitted with the side wall of the receiving block 7.

[0042] In this way, the fixed block 10 and the connection mechanism 6 are detachably connected through the formation of Velcro, and the side wall of the fixed block 10 is attached to the side wall of the receiving block 7, which can greatly improve the connection stability between the fixed block 10 and the connection mechanism 6 and effectively reduce the horizontal shaking of the pressing block 8.

[0043] Furthermore, in order to facilitate the deformation of the first arc-shaped groove 41 and the second arc-shaped groove 51 when the drainage tube and the flushing tube are inserted, a displacement groove 11 is further provided on the top surface of the receiving block 7. The displacement groove 11 is provided between the first arc-shaped groove 41 and the second arc-shaped groove 51, and both ends of the displacement groove 11 parallel to the axis of the first arc-shaped groove 41 or the second arc-shaped groove 51 are provided with through holes.

[0044] Furthermore, after the installation of the drainage tube and the flushing tube is completed, in order to prevent the first arc-shaped groove 41 and the second arc-shaped groove 51 from deforming, an insertion block 12 is provided on the bottom surface of the pressing block 8. The length and width of the insertion block 12 match those of the displacement groove 11, the position of the insertion block 12 corresponds to that of the displacement groove 11, and the insertion block 12 is provided between the third arc-shaped groove 42 and the fourth arc-shaped groove 52.

[0045] In this way, after the pressing block 8 is assembled, the insertion block 12 is inserted into the displacement groove 11, which can effectively prevent the first arc-shaped groove 41 and the second arc-shaped groove 51 from deforming, thereby improving the installation stability of the flushing tube or the drainage tube in the first positioning channel 4 or the second positioning channel 5.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
