Description
Technical Field
The utility model relates to a burn patient rehabilitation apparatus field, in particular to leading-in fixing device of skin implantation in duct.
Background
For the patient with deep burn in the auditory canal, if the wound surface cannot be closed in time, the granulation hyperplasia in the auditory canal can generate contracture, and then occlusion is formed. And the wound surface necrotic tissue is dissolved, more purulent secretion is generated due to infection, the drainage is not smooth and is easy to diffuse towards the intracranial, even the intracranial infection can be caused, and great troubles are brought to the healing of patients in the future. Because the whole layer of the auditory canal skin is burnt, the auditory canal skin can only be repaired by adopting a skin grafting method. Repair faces two problems: firstly, how the skin piece leads into the duct, secondly how guarantee moderate pressure, if pressure is little, then the skin piece is difficult to survive, and the skin grafting fails, if too big, then can cause the ischemic damage of duct.
For ear canal burns, the following treatment methods are currently available: firstly, after the wound surface of the auditory canal is treated by necessary dressing change, the auditory organ can be heard and locked, and the patient is worn with a hearing aid in the later stage, so the risk of doing is as follows: purulent secretion can be continuously generated and accumulated, and can cause intracranial infection after being diffused towards the cranium; the auditory meatus is blocked, so that deafness is caused, great stress is caused to the psychology of a patient, the appearance is also influenced, and the like. Secondly, the island-shaped skin flap is transferred, in a popular way, the island-shaped skin flap is made into a cylinder, and then the transfer is guided into the auditory canal to heal, and the risk of doing so is as follows: the operation difficulty is high, the survival rate is low, and the auditory meatus cannot be effectively expanded, so that the auditory meatus is easy to contracture until being locked. And thirdly, small skin patch transplantation, namely implanting a plurality of small skin patches into the auditory canal, wherein the small skin patches are respectively expanded to form a patch, so that the wound surface is closed, and the risk is as follows: the gauze strips are needed to provide pressure in the skin grafting process, so that the displacement of the skin is easily caused, the survival rate of small skin is low, scar contracture after scabbing is obvious, and the postoperative effect is poor.
Disclosure of Invention
The utility model discloses a remedy prior art's defect, provide a skin grafting in-process skin piece does not shift, the high duct of survival rate leading-in fixing device.
The utility model discloses a realize through following technical scheme:
a skin implantation leading-in fixing device in an auditory canal is characterized by comprising a section of hard rubber tube, wherein a longitudinal slot hole is formed in the hard rubber tube, a soft rubber tube is coated outside the hard rubber tube, the edge of the soft rubber tube is sealed with the hard rubber tube, and the slot hole is exposed; the flexible rubber tube is connected with an inflatable bag through an inflation tube, and an inflation valve is arranged on the inflatable bag.
The outer diameter of the inflation tube is smaller than the inner diameter of the hard rubber tube, and the inflation tube penetrates through the hard rubber tube.
The soft rubber hose is sleeved with a positioning ring.
The soft rubber tube is externally attached with antibacterial hemostatic drugs.
The utility model has the advantages that:
the utility model is provided with the inflatable flexible rubber hose, which can keep continuous pressure on the skin after being inflated, thus being beneficial to the combination of the skin and the wound surface and preventing the ear canal contracture and locking; the setting of holding ring can carry out the accurate positioning to the skin according to the degree of depth of the surface of a wound in the duct, avoids the emergence of the phenomenon that the skin laminating is not in place. The utility model discloses a simple structure, convenient to use, the flexible operation.

FIG. 2 is a schematic cross-sectional view taken along the line A-A in FIG. 1;
FIG. 3 is a schematic cross-sectional view taken along the direction B-B in FIG. 1;
fig. 4 is a schematic view of the leather sheet of fig. 3.
In the figure, 1 hard rubber tube, 101 slotted hole, 2 soft rubber tube, 3 inflation tube, 4 inflation bag, 5 inflation valve, 6 leather sheet and 7 positioning ring.
Detailed Description
The attached drawings are specific embodiments of the invention. As shown in fig. 1 to 4, the ear canal skin-grafting leading-in fixing device comprises a hard rubber tube 1, such as a commonly used infusion tube, wherein the hard rubber tube 1 has a certain hardness and can keep a certain shape in an ear canal, a slotted hole 101 is formed in the hard rubber tube 1 along the length direction, the slotted hole 101 is through from inside to outside, then a soft rubber tube 2 is sleeved on the hard rubber tube 1, a hole is also formed in the soft rubber tube 2, the hole is superposed with the slotted hole 101, two ends of the soft rubber tube 2 and the periphery of the hole are hermetically connected with the hard rubber tube 1, namely, the soft rubber tube 2 is airtight, in order to avoid infection, an antibacterial hemostatic drug is attached to the outer wall of the soft rubber tube 2, the antibacterial hemostatic drug can be directly attached to the soft rubber tube 2, or medical gauze and the like can be used as a carrier, the antibacterial hemostatic drug is firstly soaked on the medical gauze, then, the gauze is covered on the soft rubber tube 2. A positioning ring 7 is sleeved outside the soft rubber tube 2, and the positioning ring 7 can freely slide on the soft rubber tube 2; a through hole is arranged on the wall of the hard rubber tube 1, the inside and the outside of the wall of the hard rubber tube 1 are communicated, namely the soft rubber tube 2 is communicated with the hard rubber tube 1, then an inflation tube 3 extends into the hard rubber tube 1, and the inner end of the hard rubber tube 1 is fixed on the through hole, so that the inflation tube 3 is communicated with the soft rubber tube 2. The outer end of the inflation tube 3 is integrally connected with an inflation bag 4, an inflation valve 5 is arranged on the inflation bag 4, and the inflation valve 5 is a one-way valve.
The soft rubber tube 2, the inflation tube 3 and the inflation bag 4 are all made of medical rubber.
The method is used for determining the position of the positioning ring 7 according to the depth of a wound surface by selecting a leather sheet 6 with a proper size, determining the position of the wound leather sheet 6, winding the leather sheet 6 on the soft rubber tube 2, reserving one leather sheet 6 at two ends in the winding direction, filling the reserved part into the slotted hole 101, then extending the hard rubber tube 1 into the auditory canal to enable the leather sheet 6 to be overlapped with the position of the wound surface of a patient, then opening the inflation valve 5 to ventilate the auditory canal, judging the pressure of soft rubber in the auditory canal through the pressure of the inflation bag 4, and closing the inflation valve 5 after inflation; in the inflation process, the soft rubber bulges, the perimeter of the leather sheet 6 is enlarged, and the part plugged into the slotted hole 101 is pulled out from the slotted hole 101 and is attached to the wound surface of the auditory canal. According to the doctor's advice, keep a period, discover that the gas is not enough and just recharge a little, generally about ten days of postoperative, the gassing takes out the utility model discloses can.
Other technical features than those described in the specification are known to those skilled in the art.
