Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices and relates to a disposable sterile drape for interventional surgery. Background Art

[0002] At present, hospitals generally use disposable interventional surgical drapes to isolate patients from the outside space before performing surgery. Long instruments such as catheters and infusion sets used during surgery will get tangled with each other, making the interventional table messy and untidy.

[0003] To this end, a Chinese patent discloses a tool for fixing interventional catheters and guidewires [licensing announcement number CN220513257U], which includes a drape covering the patient's skin surface and a flexible sheet fixed to the outer surface of the drape; the flexible sheet is formed with a number of through-channels for accommodating the movement of catheters or guidewires. It can classify catheters or guidewires to prevent confusion and, to a certain extent, avoid the entanglement of catheters and guidewires.

[0004] However, the following problems still exist: when in use, the catheter or guide wire is first passed through the strip channel and then extended to the intervention window, which is not only inconvenient to operate, but also may contaminate the catheter or guide wire when it comes into contact with the flexible sheet; the catheter or guide wire can move along the length of the strip channel, and the fixation effect of the catheter or guide wire is poor.

[0005] Because the tape is not sterile, the catheter or guidewire should not be taped directly to the drape during surgery. Utility Model Content

[0006] The utility model aims to solve the above problems in the prior art and proposes a disposable sterile drape for interventional surgery which can limit the displacement of instruments.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A disposable sterile drape for interventional surgery includes a drape body and a flexible sheet attached to the outer surface of the drape body, wherein the flexible sheet is provided with a plurality of slits, and the slits divide the flexible sheet into a plurality of adhesive units, wherein the inner surface of the adhesive unit is attached to the outer surface of the drape body, and the adhesive unit can be separated from the drape body under the action of external force.

[0009] When in use, first connect the infusion tube or catheter to the surgical site, then separate the adhesive unit at the corresponding position from the drape body under the action of external force, place the infusion tube or catheter between the adhesive unit in the separated state and the drape body, and then stick the adhesive unit to the outer surface of the drape body to fix the infusion tube or catheter. The fixed infusion tube or catheter will not move relative to the drape body, and has good stability. Different infusion tubes or catheters are fixed by different adhesive units to avoid mutual influence between the infusion tube and the catheter, which is convenient for operation.

[0010] In the above-mentioned disposable sterile drape for interventional surgery, the partition seam extends along the edge of the flexible sheet to the middle of the flexible sheet. The partition seam does not completely separate the adhesive unit, that is, the multiple adhesive units are connected as a whole, with good integrity, and will not cause a single adhesive unit to fall off.

[0011] In the above-mentioned disposable sterile drape for interventional surgery, the adhesive unit has a separation portion at the edge of the flexible sheet that is not bonded to the drape body. The separation portion is convenient for fingers to grasp, and the adhesive unit can be quickly separated from the drape body, thereby saving separation time and improving efficiency.

[0012] In the above-mentioned disposable sterile drape for interventional surgery, the flexible sheet is rectangular, and the plurality of the spacers extend along the width direction of the flexible sheet. Since the spacers do not completely separate the adhesive unit, the length of the spacers is smaller than the width of the flexible sheet. The flexible sheet extends along the length direction of the drape body, or is arranged obliquely relative to the drape body.

[0013] In the above-mentioned disposable sterile drape for interventional surgery, the two long sides of the flexible sheet are provided with slits, and the slits provided on one long side do not intersect with the slits provided on the other long side. The purpose is also to connect multiple adhesive units into one.

[0014] In the above-mentioned disposable sterile drape for interventional surgery, the sum of the lengths of the single slit provided on one of the long sides and the single slit provided on the other long side is less than the width of the flexible sheet. When the slits provided on one of the long sides and the slits provided on the other long side are arranged one by one opposite to each other, the slits on both sides will not intersect.

[0015] In the above-mentioned disposable sterile drape for interventional surgery, a medical adhesive layer is formed on the inner surface of the flexible sheet. The flexible sheet is adhered to the drape body through the medical adhesive layer. In order to prevent the separation portion from adhering to the drape body, the medical adhesive layer is not provided on the inner surface of the separation portion, or an isolation layer is attached to the medical adhesive layer at the separation portion, so that the medical adhesive layer at the separation portion does not adhere to the drape body.

[0016] Alternatively, a medical adhesive layer is provided on the outer surface of the drape body, and the flexible sheet is adhered to the medical adhesive layer. No medical adhesive layer is provided on the inner side of the drape body located at the separation portion.

[0017] In the above-mentioned disposable sterile drape for interventional surgery, an intermediate layer is attached to the outer surface of the drape body, and the flexible sheet is attached to the intermediate layer. The intermediate layer, the flexible sheet and the drape body are made of the same material, and the thickness of the intermediate layer is greater than that of the drape body, so as to avoid the drape body being torn when the drape unit is separated and attached.

[0018] In the above-mentioned disposable sterile drape for interventional surgery, an intervention window is provided on the drape body, and the flexible sheet is located on a side of the intervention window routing.

[0019] Compared with the prior art, the disposable sterile drape for interventional surgery has the following advantages: the fixed infusion tube or catheter will not be displaced relative to the drape body, the stability is good, different infusion tubes or catheters can be fixed by different adhesive units, the mutual influence between the infusion tube and the catheter is avoided, and the operation is convenient.
