Description

Waist cisterna magna drainage tube sneak-running remaining guiding device

Technical Field

The utility model relates to the field of medical equipment, especially relate to a waist cisterna magna drainage tube is latent to be stayed guiding device.

Background

At present, two types of modes are adopted for the retention of the clinical lumbar cisterna drainage tube: 1. direct puncture implantation mode: after the lumbar puncture needle successfully punctures the lumbar cisterna magna, the needle core is withdrawn, and the drainage tube is placed in through the puncture needle cavity. The method is currently the most widely applied general method at home and abroad, and has the defects of simple and convenient operation and no transverse creeping distance. 2. Other modes are as follows: and a, on the basis of successful direct puncture tube placement, making a skin incision beside an original skin puncture hole, poking a subcutaneous tunnel by using vascular forceps, and then leading out the tail section of a drainage tube at the original puncture hole through the incision. The method has the defects of very large wound, complex operation, limited side-opening distance, limited depth of diving, limited maintaining time of the belt tube and the like, and once the indwelling drainage tube needs to be punctured again, the lumbar intervertebral space is often required to be replaced because the skin condition of the lumbar intervertebral space is influenced by the operation. And b, or, after bending and shaping the puncture needle by a certain radian, puncturing the skin from the side opening position towards the original puncture hole direction, and then reversely leading out the tail section of the drainage tube through the needle cavity of the puncture needle. The method is simple to operate and has a diving effect from the appearance, and actually, four obvious defects exist because the bent and shaped puncture needle can only be poked through the original puncture hole: the drainage tube is easy to be damaged, the skin at the puncture hole is not covered enough, even the drainage tube is exposed locally, the whole diving is too shallow, and the diving distance is limited. The method has uncertain effect and even poor effect and complicated operation, and only a small part of doctors are occasionally applied clinically.

The direct puncture implantation mode has the advantages that the puncture channel is linear, the part of the indwelling lumbar cisterna drainage tube between the lumbar cisterna and the skin puncture hole is linear, the distance in soft tissues is short, peritubular seepage and drainage tube looseness are easy to occur along with the time extension, and even retrograde infection is caused, particularly for patients with severe obesity or obvious emaciation. For example: usually, the drainage treatment time of a neurology patient needing to put a lumbar cistern drainage tube is 1-3 weeks, and part of patients may need to take the tube for a longer time. Usually, after the drainage tube is left in place for 1 week, local skin maceration, whitening and even secretion appear around the drainage tube, and the drainage tube becomes loose. Even if the local dressing change frequency is specially increased for prolonging the tube carrying time and the turning over activity is reasonably assisted to avoid dragging the drainage tube, the situation is difficult to avoid. If the drainage tube is not suitable to be kept in place, a new drainage tube is frequently punctured again in the lumbar intervertebral space to avoid the accident of the drainage tube. While it is more difficult to maintain the drain in significantly obese or wasting patients: when the body turning-over assisting device assists an obese patient to turn over, the body is heavy, the subcutaneous fat layer is thick, the skin surface of the waist and the back and the spinous process of the lumbar vertebra can deform obviously when the body position changes, and the body weight and the obesity degree are in positive correlation. When the nursing personnel assists in turning over, the nursing personnel often firstly pushes the skin and the subcutaneous soft tissues to move to a certain degree and then the patient starts to turn over integrally, so that the drainage tube in the body is pulled to generate tension or relative motion with the tissues around the tube to loosen, and even the drainage tube partially moves in the subcutaneous soft tissues, thereby being easy to carry out secondary liquid seepage and retrograde infection; in addition, for patients with obvious emaciation, the conditions of loose drainage tube and leakage of cerebrospinal fluid along the peripheral gap of the drainage tube are easily caused due to the lack of sufficient fat layer protection from skin to the supraspinal ligament of lumbar vertebra, and the leakage of cerebrospinal fluid through the periphery of the tube even occurs in the tube placement process of the conventional direct puncture mode, so that the leakage is easy even if the skin around the puncture hole is sutured. Although the 'movement' of the drainage tube in the body is not easy to occur when the patient turns over, the reverse infection is easy to occur due to the short barrier distance and easy liquid seepage. The lumbar cisterna drainage tube is more difficult to maintain for patients with significant obesity and patients with significant emaciation.

The retention effect of the above mentioned modes on the lumbar cisterna magna drainage tube is not ideal: the lumbar cisterna magna drainage tube is difficult to maintain and short in maintenance time, not only is the nursing difficulty increased, but also the medical workload is increased by frequently changing the dressing of the wound and even puncturing the tube again, and the material loss, the economic burden and the pain of a patient are increased. The key is that the defects of the traditional indwelling mode lead to that the drainage tube is easy to loosen, seep liquid and even retrograde infection, and as a result, the drainage maintaining time is shortened, the risk of retrograde infection is increased, and the treatment effect is finally influenced and even new infection is caused. And for patients with poor skin conditions of the waist and the back, such as: inflammation, scar and the like of the skin near the puncture area seriously affect the implementation of the indwelling lumbar cisterna drainage tube method due to the difficulty of avoiding.
