Background

The continuous drainage of the lumbar cisterna refers to a closed and sterile technology for continuously draining cerebrospinal fluid from the subarachnoid cavity to the outside of the body, and is widely applied to craniocerebral trauma diseases such as subarachnoid hemorrhage, intracranial infection, cerebrospinal fluid leakage, hydrocephalus and the like. The drainage tube is usually arranged in a way that the drainage tube is extended and fixed along the lateral direction of the spine to the head and extends out from the shoulder to be fixed at the bed head, so that the drainage tube is prevented from being folded, and the patient can turn over conveniently. At present, a plurality of sterile transparent application plates are generally adopted to alternately fix the drainage tube, and the fixing mode has the following problems: firstly, it is not reliable to fix, and it is easy to turn up the edge, loosen and take off to apply ointment or plaster to lead to drainage tube distortion, folding, drop even, easily cause stifled pipe and unintended tube drawing. Secondly, after the puncture point is fixed by adopting the sterile gauze and the application, the puncture part is shielded, so that medical personnel can not conveniently observe whether red swelling, blood seepage and liquid seepage exist, and the incidence rate of local skin allergy damage and catheter related infection of a patient is increased. Thirdly, the pipe diameter of drainage tube is little, is not convenient for adopt the high platform method of lifting to fix, and the drainage tube direct mount easily leads to pressure nature damage on patient's back skin. Fourth, the drainage tube is fixed through a plurality of applications, and is with high costs, and the change of being not convenient for reduces the efficiency of changing moreover.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the utility model discloses the fixed applying ointment or plaster of waist cisterna cerebrospinal fluid drainage tube non-contact, including applying paster 1, the bottom surface that applies paster 1 is the skin contact surface and scribbles the adhesive, and the bottom surface that applies paster 1 promptly is used for directly pasting on patient's skin, and it is best to choose for use soft antianaphylaxis material to make to apply paster 1, guarantees the travelling comfort of using. The outer contour of the patch 1 can be circular, rectangular or other irregular shapes, a through hole 2 is arranged in the middle of the patch 1, the through hole 2 is preferably a circular hole, and a gap 3 is also arranged between the outer edge of the patch 1 and the through hole 2. The slit 3 can be a straight line or a curved line, preferably a straight line, and the slit 3 is used for placing the drainage tube into the through hole 2 from the slit 3, so that the drainage tube is prevented from penetrating into the through hole 2. After the patch 1 is adhered to the skin around the puncture site, the through-hole 2 is used to expose the puncture site.

The top surface of paster 1 sets up epiphragma 4, and epiphragma 4 optional uses ventilative or airtight material, but the best material that is transparent and ventilative, is convenient for later observe the puncture site, fixes through the viscose between the top surface of epiphragma 4 and paster 1. The cover film 4 may be torn or stuck on the top surface of the applicator 1. The cover film 4 has two functions, on one hand, after the drainage tube is put into the through hole 2 through the gap 3, the cover film 4 is pasted on two sides of the gap 3, so that the patch 1 is pasted into a whole; on the other hand, the cover film 4 is used for covering the through hole 2, so that the skin of the puncture position is protected in a non-contact mode, and meanwhile, the observation is facilitated, so that the condition of the puncture position can be observed and timely nursing can be facilitated. The cover film 4 can be an independent component, when in use, the drainage tube is tidied after the dressing piece 1 is stuck to the puncture part, and the cover film 4 is covered on the top surface of the dressing piece 1. In order to avoid the loss of the cover film 4 and at the same time avoid the problem that the cover film 4 is not easy to be positioned accurately, a part of the cover film 4 is fixedly arranged on the top surface of the patch 1, i.e. this part cannot be torn off from the top surface of the patch 1, and another part of the cover film 4 covers a temporary protective film, which part can be attached to the top surface of the patch 1 after tearing off the temporary protective film, ensuring sterility requirements, see fig. 1 and 2. The entire face of the cover film 4 in contact with the patch 1, i.e. the bottom face of the cover film 4, may be coated with adhesive, preferably by providing the adhesive only in the area where the cover film 4 is in direct contact with the patch 1, and not in the area corresponding to the through-hole 2.

The paster 1 is softer relatively, in order to guarantee the stable in shape of through-hole 2, avoids the deformation of through-hole 2 too big, and the edge of the through-hole 2 of paster 1 sets up round silica gel ring 7, and silica gel ring 7 is the disconnection form in the gap 3 department of paster 1, avoids silica gel ring 7 to influence the drainage tube and puts into through-hole 2 through gap 3. The cover film 4 is preferably provided with an adhesive in a circle corresponding to the silicone ring 7 so that the cover film 4 can be simultaneously stuck and fixed to the silicone ring 7.

One side of the patch 1 is connected with a fixing belt 5, and the bottom surface of the fixing belt 5 is a skin contact surface and coated with adhesive. The position of the fixing strip 5 and the slit 3 relative to the through hole 2 may be arbitrarily arranged, for example, the fixing strip 5 and the slit 3 are located on opposite sides of the through hole 2, see fig. 1. The fixing band 5 is used for being stuck on the skin of a patient and fixing the drainage tube, and the bottom surface of the fixing band 5 is used for being directly stuck on the skin of the patient, so that the fixing band is preferably made of soft antiallergic materials. The fixing belt 5 is in a strip shape and can be pasted along the back of the patient. The fixing belt 5 and the application sheet 1 can be made of different materials or the same material; the fixing band 5 and the application sheet 1 can be separated from each other but placed in close contact with each other when in use, or can be fixedly connected into a whole; for example, the two are themselves integral, and the fastening tape 5 and the applicator sheet 1 are of the same material. Specifically, the application sheet 1 and the fastening tape 5 are both made of an ester film material, and the bottom surfaces of the application sheet 1 and the fastening tape 5 are both coated with acrylic as an adhesive.

The top surface of fixed band 5 sets up draw-in groove 6 along the length direction of fixed band 5, and draw-in groove 6 is used for fixed drainage tube, and the top surface of applying ointment or plaster 1 sets up the draw-in groove 6 that link up with draw-in groove 6 of fixed band 5 and extends to the through-hole 2 department of applying ointment or plaster 1's middle part, and when through-hole 2 department set up silica gel ring 7, also set up draw-in groove 6 on the silica gel ring 7, see fig. 1 and fig. 3. The clamping grooves on the patch 1, the fixing band 5 and the silica gel ring 7 are the same in shape and are all used for fixing the drainage tube, so that the clamping grooves are marked as clamping grooves 6. The drainage tube penetrating out of the skin is directly clamped into the clamping groove 6 of the silica gel ring 7 and the clamping groove 6 of the patch 1, and then is clamped into the clamping groove 6 of the fixing band 5 to realize the fixation. In order to fix the drainage tube, the cross section of the clamping groove 6 is in the shape of a major arc bow, the angle of the major arc bow is preferably 270 degrees +/-10 degrees, and the drainage tube is automatically fixed after being clamped into the clamping groove 6; or, set up fixed sticky tape at 6 top surfaces of draw-in groove, draw-in groove 6 can be arbitrary shape this moment, as long as can hold the drainage tube can. The clamping groove 6 on the top surface of the patch 1 is linear or continuous S-shaped, and the clamping groove 6 of the fixing belt 5 is linear or continuous S-shaped. The clamping groove 6 is continuous S-shaped, so that the friction force between the drainage tube and the clamping groove 6 can be increased, and the risk of unplanned tube drawing caused by traction of the drainage tube is reduced.
