Description
Technical Field
The invention relates to the technical field of medical abdominal cavity instruments, in particular to a temporary abdominal cavity closing device capable of controlling pressure and measuring pressure.
Background
In the process of open wound treatment of abdomen or operation treatment in abdominal cavity, because the organ tissues of intestinal tract, mesentery and the like in abdominal cavity of a patient have serious edema, the first-stage operation cannot be performed, the abdominal cavity needs to be opened temporarily, if the infection is caused, the treatment such as long-term abdominal cavity flushing and drainage is also needed, and the abdominal cavity can be closed by the second-stage operation after the condition of the disease is improved and the pressure of the abdominal cavity is reduced. The simple temporary closure of the abdominal cavity often leads to intra-abdominal high pressure and secondary abdominal compartment syndrome due to aggravated organ and tissue edema in the abdominal cavity, and further causes multi-organ dysfunction failure in the abdominal cavity, and even leads to death of patients in severe cases. Aiming at the problem, in order to avoid serious consequences caused by overhigh pressure in the abdominal cavity, a plurality of abdominal operations are often performed in clinical treatment, so that the operation not only greatly attacks the body of a patient and is unfavorable for the recovery of the state of an illness, but also increases the medical burden.

The adhesive film 10 comprises a bottom film 11 and two winding films 12, wherein the bottom film 11 is used for being adhered to skin around an incision, one ends of the two winding films 12 are respectively adhered to two sides, located on the incision, of the bottom film 11, and the other ends of the two winding films 12 are wound on the closing component 20. The edge of the bottom film 11 is adhered to the skin around the incision to form a closed environment inside the opened abdominal cavity, so that the inside of the abdominal cavity is isolated from the outside, thereby maintaining a certain abdominal pressure and simultaneously avoiding dehydration and hypoproteinemia of the patient caused by infection and excessive exudation inside the abdominal cavity. The winding film 12 is connected with the rotating shaft 21 and the bottom film 11, so that the phenomenon that the bottom film 11 is deformed due to the fact that the rotating shaft 21 directly pulls the bottom film 11 is avoided, and a buffering effect is achieved.
Specifically, the bottom side of the closed tube 22 is disposed on the bottom film 11, and the ends of the two winding films 12 far away from the bottom film 11 are wound on the rotating shaft 21 through the gap. Through rotating the rotating shaft 21, the end parts of the two winding films 12 are all shrunk and wound on the rotating shaft 21, so that the end parts of the two winding films 12 far away from the rotating shaft 21 pull the bottom films 11 at the two sides of the incision to be tightened towards the middle, and then the skin at the two sides of the incision is pulled to be closed, and the abdominal incision is closed.
Referring to fig. 3, the closing element 20 further includes two auxiliary rotating pipes 23, the two auxiliary rotating pipes 23 are respectively rotatably sleeved on the outer sides of the ends of the rotating shaft 21 located at the outer sides of the two ends of the closing pipe 22, one end of the winding film 12 away from the bottom film 11 is divided into a middle winding point 121 and two end winding points 122, the middle winding point 121 is wound on the rotating shaft 21, and the two end winding points 122 are respectively wound on the auxiliary rotating pipes 23.
Because the incision is wide in the middle and narrow in the two ends, the skin in the middle and the skin at the two ends of the incision are respectively pulled and folded through the arrangement of the middle winding point 121 and the two end winding points 122, so that the incision can be completely closed. When the middle part of the incision needs to be pulled, the rotating shaft 21 is rotated to pull the skin in the middle part of the incision, so that the middle part of the incision is closed, and when the two ends of the incision need to be pulled, the auxiliary rotating pipe 23 is rotated to pull the skin at the two ends of the incision, so that the two ends of the incision are closed.
Preferentially, the rotating shaft 21 is provided with a first limiting part, the first limiting part comprises a first limiting block 24, the side surface of the rotating shaft 21 is provided with a first limiting groove 211 along the axis direction, the top end of the first limiting block 24 is hinged to the top side of the end surface of the auxiliary rotating pipe 23, and the bottom end of the first limiting block 24 can be rotatably inserted into the first limiting groove 211 and is in sliding connection. When the first limiting block 24 is rotated, one end of the first limiting block 24, which is far away from the auxiliary rotating pipe 23, is inserted into the first limiting groove 211, so that the auxiliary rotating pipe 23 is connected with the rotating shaft 21, synchronous rotation is realized, the rotating shaft 21 is rotated, the rotating shaft 21 and the auxiliary rotating pipe 23 synchronously rotate, and simultaneously one end, which is far away from the bottom film 11, of the winding film 12 is tightened, and then the skin around the incision is drawn to be folded towards the middle part; when the rotating shaft 21 needs to be rotated independently, the first limiting block 24 is separated from the first limiting groove 211, and the rotating shaft 21 is rotated to pull the skin in the middle of the incision independently.
Preferably, the auxiliary rotating pipe 23 is provided with a second limiting part, the outer diameter of the auxiliary rotating pipe 23 is smaller than the inner diameter of the closed pipe 22, the second limiting part includes a second limiting block 25, the bottom end of the second limiting block 25 is arranged on the top side surface of the auxiliary rotating pipe 23, which is far away from the first limiting block 24, a second limiting groove 221 is formed in the end surface of the closed pipe 22 along the axis direction, and the top end of the second limiting block 25 can be inserted into the second limiting groove 221. After the skin on both sides of the incision is folded towards the middle, the auxiliary rotating pipe 23 is slid to insert the second limiting block 25 into the second limiting groove 221, so that the auxiliary rotating pipe 23 cannot rotate relative to the closing pipe 22, and meanwhile, the end part of the first limiting block 24 is inserted into the first limiting groove 211, so that the rotating shaft 21 cannot rotate relative to the auxiliary rotating pipe 23, and the incision is kept in a closed state.
As shown in fig. 3 and 4, in the present embodiment, the pressure measuring assembly 30 includes a pressure measuring catheter 31 and a sealing member 32, one end of the pressure measuring catheter 31 is used for being inserted into the abdominal cavity, the other end of the pressure measuring catheter 31 extends to the outside through the adhesive film 10, the sealing member 32 is disposed at the end of the pressure measuring catheter 31 located at the outside for blocking the end of the pressure measuring catheter 31, and the sealing member 32 is provided with a pressure measuring gauge 333 or a pressure measuring balloon, and the pressure measuring gauge 333 or the pressure measuring balloon is used for detecting the pressure in the abdominal cavity, so as to determine whether the incision is closed and open the size of the incision gap, so that the pressure in the abdominal cavity is within a normal value range, and thus the patient is prevented from getting worse. When the air bag is used for detecting the intra-abdominal pressure, the expansion degree of the air bag is pinched by hands, or the pressure gauge 333 is used for detecting the intra-abdominal pressure, and the numerical value on the pressure gauge 333 is checked, so that whether the intra-abdominal pressure is in the normal range is judged, and the closing degree of the incision is further pulled, and the intra-abdominal pressure is in the normal range.
