Description

Hip pad for lithotomy position operation

Technical Field

The invention relates to the field of medical auxiliary articles, in particular to a hip pad for an lithotomy position operation.

Background

The lithotomy position is a common operation position, and is widely applied to operations of departments such as general surgery, urology surgery, obstetrics and gynecology, and the like, such as hysteroscopy operation, cystoscopy operation, induced abortion, laparoscopic rectal cancer radical operation, abdominoperineal-perineal combined rectal cancer radical operation, and the like. For the operation adopting the lithotomy position, a cotton sterile treatment sheet is often laid under the buttocks of a patient before the operation to play a role in isolating the sterile area of the operation, but the following problems can be caused in the actual operation process:

1. the operation of lithotomy position often needs to operate in the perineum region, and blood, intestines content, urine, flush fluid etc. often can soak and fill up the treatment piece of cloth under patient's buttockss in the operation process, make the art wild dirty and disorderly, and can lead to the aseptic treatment piece of cloth of drenching to lose its isolation effect.

2. The treatment towel under the buttocks is not flattened when being laid on a sheet, a patient is in a lithotomy position for a long time in the operation process, and the protrusion part on the treatment towel can press the sacrococcygeal skin of the patient, so that pressure sores are formed.

3. To the operation of collecting the sample and keeping out the pathology after needs art, it is loaded down with trivial details to keep out the pathology operation repeatedly, and causes the losing of pathology sample easily when the exudate is more bled.

Publication No. CN206424271U discloses a bladder lithotomy position protection pad, comprising: the cushion cover is made of cotton materials, one end of the cushion cover is provided with a filler inlet, polyester fibers are used as supporting fillers, the cushion cover has a certain supporting effect, and a doctor can easily complete the operation of placing the body position by one person; after the protective pad is polluted, the protective pad can be reused after being washed with other clothes in a hospital, and the manufacturing cost is low; the manufacturing method is simple, and has universal applicability and popularization. But it does not have the ability of collecting the operation waste liquid, and can not solve the problems of operation field messiness and tedious sample retention after operation.

Publication No. CN204890771U discloses a disposable perineum rinsing pad, which consists of a skin-friendly layer, a funnel and a drainage tube; the design ensures that the washing disinfectant is easy and feasible to collect, and reduces the ground pollution; disinfectant is effectively absorbed, and dryness is kept to prevent infection; improve nurse's work efficiency. But it does not have a supporting function, and skin contacts the cotton-sandwiched layer stained with waste liquid for a long time, which easily causes skin shrinkage, and the device is not designed to filter the solid sample in the waste liquid.

In conclusion, a special pad for lithotomy position surgery is needed, which can improve the comfort of patients, keep the surgery field clean, play a role in sterile isolation and facilitate the preservation of postoperative pathology.

Disclosure of Invention

In view of the above, the invention provides a hip pad for lithotomy position operation, which can solve the existing problems.

For this purpose, the present invention is implemented by the following technical means.

A hip pad for lithotomy comprises a thickening layer, a hip pad main body, a conical bag, an indentation area, a filter and a drainage port;

the buttock pad main part is flat cuboid structure, and its upper surface sets up the thickening layer, and is further, buttock pad main part thickness is 0.25cm-1cm, with the thickening layer material is silica gel.

The upper surface profile of the thickening layer is one of an inwards concave polygon, an inwards concave combined graph or an inwards concave arc, and further, the thickness of the thickening layer is 0.5cm-1 cm.

Furthermore, a transition fillet is arranged at the joint of the concave end face of the thickening layer and the hip pad main body, and further, agar gel is filled in the thickening layer.

Furthermore, the upper surface of the hip pad body exposed from the concave side in the thickening layer is a slope surface inclined from a narrower end to a wider end, and the slope is 5-15 degrees.

The tapered bag is a tapered through structure, the diameter of an upper opening is larger than that of a lower opening, and the edge of the upper opening is fixedly connected with the end face of the wider end of the hip pad body, which corresponds to the inner concave side of the thickened layer, in equal length.

The drainage port is of a thin-wall through structure and is connected with the opening at the lower part of the conical bag through the filter.

The filter is one of column or cubic structure, and internally mounted has the filter core, and further, the filter core of filter is the sponge filter core.

Furthermore, the material of the external support structure of the filter is one of metal, plastic or rubber.

And the conical bag is transversely indented 5cm above the filter to form the indentation area, and further the conical bag is made of plastic.

The invention has the following advantages:

1. after the treatment towel under the hip is laid in the lithotomy position operation, the hip pad is placed under the hip, and the waterproof property of the silica gel material can prevent the treatment towel under the hip from being soaked, so that the aim of isolating a sterile area is fulfilled.

2. The main stress points (the ischial tuberosities on two sides and the sacral tail part behind the connecting line thereof) of the body of the lithotomy patient are positioned in the thickening layer of the hip pad, the gel filled in the hip pad can effectively dissipate heat, and simultaneously, the stress deformation is realized, so that the stress surface forms proper curvature, the use comfort degree is obviously improved, and the pressure sore is effectively prevented.

3. Thickening layer and buttockss pad main part combination department are excessive fillet design and collection region slope design, and the make full use of difference in height produces the waste liquid with the art and collects to the conical bag in, has kept the wild clean and tidy of art.

4. The conical bag is connected with the hip pad main body, the tail end of the conical bag is arranged in the medical garbage can, waste liquid is fully collected, the operation field and the operating room are prevented from being polluted, and the bleeding amount in the operation is easy to calculate.

5. The design of indentation district and filter effectively avoids the sample to lose, realizes convenient and fast pathology and leaves the appearance.
