Description

A wound cleansing and dressing change device for the care of LU601203

Fracture injuries

Technical area

The present invention belongs to the field of medical devices and relates in particular to a device for cleaning wounds and changing dressings.

Bandages in the care of fracture injuries.

Technology in the background

In the field of medical nursing, wound care is essential.

Fracture injuries are a crucial aspect. Bone fractures not only lead to structural damage to the skeleton, but are often accompanied by soft tissue injuries that cause open wounds. These wounds must be regularly cleaned and the dressing changed during the healing process to remove necrotic tissue, reduce the risk of infection, and promote wound healing.

The conventional methods for cleaning and changing dressings in

However, fracture injuries have numerous shortcomings. On the one hand, manual treatment is problematic.

The cleaning process is cumbersome and time-consuming: The nursing staff has to do the

Manually guiding the cleaning device and rinsing the wound several times not only increases the complexity of the procedure but can also lead to secondary wound injuries if used improperly. Furthermore, the cleaning effect of traditional methods is limited, meaning that complete cleanliness of the wound is not guaranteed.

The wound surface often cannot be guaranteed, which increases the risk of infection.

Furthermore, splashing and leakage can easily occur during the rinsing process.

Cleaning fluid can get into the patient's clothes or bed, leading to bacterial residue and thus to an infection.

This can lead to secondary infection.

Therefore, the present invention discloses a device for cleaning

Wounds and changing dressings in the care of fracture injuries.

Content of the invention

To achieve the aforementioned technical effects, the invention is implemented through the following technical solution:

Air hoses were attached, which were connected to the ring-shaped air cushion; the

The inner wall of the fixing ring is provided with the ring-shaped air cushion; the cleaning function unit is rotatably mounted in the middle of the fixing rings on both sides.

The cleaning unit includes: a mounting tube body, a lid, a spray nozzle, a threaded rod, a vacuum pump and a drainage ring.

At the upper end of the mounting pipe body is an integrated housing; the inner wall of the mounting pipe body is symmetrically provided with open drainage channels; symmetrically arranged drainage rings are located on both sides of the mounting pipe body; drainage pipes arranged in series LU601205 are installed at the end of the open drainage channels, leading into the drainage rings; the drainage rings, symmetrically arranged on both sides, are connected to each other via a T-shaped drainage pipe; the end of the T-shaped drainage pipe is removable with the

The vacuum pump is connected; in the middle it is detachably connected to the collection bottle.

Inside the housing is a horizontally sliding mounted

Spray nozzle and a rotatably mounted threaded rod; the upper part of the housing is detachably connected to the lid; the threaded rod is screwed to the spray nozzle so that the position of the spray nozzle can be adjusted by turning the threaded rod.

Furthermore, a telescopic hose is attached to the upper side of the spray nozzle; the head end of the telescopic hose is detachably connected to the lid.

The open drainage channel is designed as a truncated cone to accommodate the water in the

To direct the penetrating flushing solution from the mounting pipe body to the end of the open drainage channel and to guide it through the drainage pipes into the interior of the drainage rings.

The vacuum pump is connected to the collection bottle via a hose; the operation of the vacuum pump creates a vacuum in the collection bottle, so that the liquid from the drainage rings is drawn under vacuum into the

The collection bottle is sucked in.

The head end of the telescopic hose is detachably connected to a supply hose, which feeds the rinsing solution so that the spray nozzle can take in the rinsing solution.

The advantageous effects of this invention are:

Precise fixation and prevention of secondary injuries: The

The fixation device uses a ring-shaped air cushion bag in combination with a pressure pump for adjustable inflation, allowing the device to automatically adapt to the shape of the injured limb and thus avoiding localized pressure from conventional rigid clamps. The symmetrically arranged fixation rings and air cushions ensure even pressure distribution. Combined with the rotatably connected cleaning unit, this ensures that the affected limb remains stable and securely positioned during cleaning, effectively reducing the risk of secondary injuries caused by the treatment.

Controlled cleaning and efficient wastewater disposal: The

The cleaning unit is equipped with a drive mechanism powered by a threaded rod.

Equipped with a spray nozzle. The position and the spray pattern can be adjusted by turning the threaded rod.

The nozzle's rinsing area must be precisely adjusted to ensure complete coverage of the

To ensure wound area — especially suitable for irregular wounds (such as open fractures with soft tissue injuries).

Furthermore, the frustoconical open drainage channel, the drainage ring and the vacuum pump form a closed-loop system for wastewater disposal.

The wastewater is conveyed along the truncated cone-shaped open drainage channel to its base and then through the drainage pipes into the collection ring. A vacuum pump creates a negative pressure in the collection tank, LU601203, which quickly directs the flushing fluid into the collection bottle. This prevents

It eliminates residues or splash contamination and meets the sterility requirements in medical practice.

Easy operation and multifunctional adaptability: The spray nozzle is connected to the external rinsing solution source via a telescopic hose, enabling continuous rinsing without the need for frequent device changes. The mounting tube body and lid are removable, allowing for easy disassembly for disinfection or replacement of consumables and reducing the risk of cross-contamination.
