Description
Technical Field
The invention relates to the field of medical equipment, in particular to a neonatal abdominal cavity surgical bag.
Background
The abdominal fissure is an congenital developmental deformity caused by viscera dislocation due to the defect of the components of the paraumbilical abdominal wall, and is commonly found in immature infants, low birth weight infants and the like. If the intestinal canal is exposed outside the body for a long time, the intestinal perforation or necrosis is easily caused by blood supply disorder, and even the life safety of the infant is endangered; part of the infant can be treated by directly pressing the viscera back to the abdomen and suturing the cracked part of the abdomen, however, for the other part of the infant, due to the slower development of the abdominal cavity and smaller volume, the exposed viscera cannot be contained, the exposed viscera needs to be protected firstly, and after the abdominal cavity of the infant is gradually expanded, the viscera is gradually pressed into the abdominal cavity of the infant; in this case, it is necessary to protect the viscera that are not completely pushed into the abdominal cavity by an abdominal cavity surgical pouch, and to avoid various problems caused by the long-term positioning of the viscera outside the abdominal cavity to the physical development of the infant, it is necessary to shorten the time for pushing the viscera into the abdominal cavity as much as possible.
For example, an adjustable abdominal viscera accommodating bag disclosed in Chinese patent literature has an announcement number of CN111419496A and comprises a medical silica gel bag, wherein the bottom end of the medical silica gel bag is sealed, a suspension hole is formed in the bottom end of the medical silica gel bag, and two belt-shaped components are connected with the bottom end of the medical silica gel bag; the bag mouth of the medical silica gel bag is connected with a silica gel ring, a binding belt ring with an adjustable inner diameter is arranged in the silica gel ring, and the silica gel ring is arranged in a sealing way; the medical silica gel bag body is also provided with a sealing clamp; the bag body of the medical silica gel bag is provided with bag body scale marks; the adjustable abdominal viscera accommodating bag provided by the invention has the advantages of reasonable structural design, adjustable inner diameter, convenience in suspension, convenience in bag clamping, high efficiency, economy and practicability; the utility model has strong practical value, however, the disadvantage of the patent is that if the position of the sealing clamp is not adjusted in time in the process of the viscera moving downwards to enter the abdominal cavity, certain negative pressure is generated in the medical silica gel bag, so that the abdominal cavity expansion and the viscera entering the abdominal cavity are not facilitated, the operation time is prolonged, and the operation risk is increased.
Disclosure of Invention
The invention aims to solve the problems that in the prior art, viscera are not easy to enter the abdominal cavity due to slow abdominal cavity expansion in the process of gradually pressing the viscera of a split-abdomen infant into the abdominal cavity through an abdominal cavity operation bag, the operation time is prolonged and the operation risk is increased, and provides the neonatal abdominal cavity operation bag which can protect the viscera and provide certain pressure for the viscera, so that the abdominal cavity expansion and the viscera entering the abdominal cavity are facilitated to a certain extent.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
the invention discloses a neonate abdominal cavity operation bag, which comprises a silica gel bag, wherein the silica gel bag comprises an upper opening and a lower opening, a flexible pipe is arranged on the inner side of the silica gel bag, the flexible pipe is spirally attached to the inner side of a silica gel belt, the flexible pipe penetrates through the upper opening and is communicated with a water storage tank, and a closing ring sleeved outside the silica gel belt is arranged at the upper opening.
The lower opening is sleeved outside the abdominal cavity of the infant, the water storage tank is used for filling water into the flexible pipe, and the flexible pipe after water filling forms certain pressure on the viscera of the infant in the silica gel bag, so that the viscera can enter the abdominal cavity, and the abdominal cavity can be expanded; the continuous downward movement of the closing ring can reduce the space inside the silica gel bag along with the downward movement of the viscera, so that negative pressure is avoided; in addition, because the flexible pipe passes the binding off ring, when the binding off ring moves downwards, the flexible pipe that originally is located the side of silica gel bag can gradually draw close to the position of binding off ring to make a portion of flexible pipe be located the upper portion of infant viscera all the time, thereby ensure to have a top-down pressure to infant viscera, more do benefit to the viscera and get into the peritoneal cavity, and the expansion of peritoneal cavity.
Preferably, the abdominal cavity operation bag further comprises a hanging seat, a hook is arranged on the upper side of the hanging seat, and the water storage tank is arranged in the hanging seat; the hanging seat can be hung on the bracket, so that the water storage tank is convenient to install.
Preferably, the suspension seat comprises a cylindrical cover shell positioned outside the silica gel bag, and the cover shell can protect the silica gel bag and the viscera of the infant in the silica gel bag to a certain extent.
Preferably, a guide rail is arranged on the inner wall of the housing, a counterweight sliding block is arranged in the guide rail, and the counterweight sliding block is connected with the closing ring through a connecting rod; through the structure, the closing ring can automatically move downwards under the action of the gravity of the balancing weight, closes the silica gel bag, can keep certain pressure on the viscera of the infant without manual operation for many times, and avoids forming negative pressure in the silica gel bag, thereby being beneficial to the expansion of the abdominal cavity and the viscera entering the abdominal cavity.
Preferably, a temperature control system is arranged in the water storage tank; the temperature control system can control the water temperature of the water storage tank so as to enable the water temperature to be the same as the body temperature of a human body, thereby avoiding damage to viscera of an infant.
Preferably, a water circulation system is arranged in the water storage tank, and the water circulation system can enable water in the flexible pipe to circulate in the water storage tank, so that temperature control is more stable, and a certain pressure of the flexible pipe to the viscera of the infant can be ensured.
Preferably, the caliber of the lower opening of the silica gel bag is 6-15cm.
Therefore, the invention has the following beneficial effects: (1) The flexible tube can keep certain pressure on the viscera of the infant, so that the expansion of the abdominal cavity and the entry of the viscera into the abdominal cavity are facilitated; (2) can play a better role in protecting the viscera of the infant; (3) The viscera of the infant can be in the same temperature environment as the interior of the human body by controlling the temperature, so that damage to the infant is avoided; (4) The automatic closing-in of the closing-in ring can be realized without manual operation.
