Rotary jet flow sprayer structure for washing gun

Abstract

The invention discloses a rotary water jet flow nozzle structure for a washing gun. A head body combination port, a liquid medicine spraying pipe, a spiral generator, a liquid medicine recycling pipe,a first protection cover and a second protection cover are included. The liquid medicine spraying pipe is sleeved with the liquid medicine recycling pipe, the liquid medicine spraying pipe and the liquid medicine recycling pipe are connected in a washing gun cavity, and the head end of the liquid medicine recycling pipe is connected with the position of the head body combination port. The spiralgenerator is fixedly connected to the outlet position in the liquid medicine spraying pipe through a support. The outlet position of the liquid medicine spraying pipe is provided with a conical cavitystructure and a transition area. The first protection cover is connected with the liquid medicine spraying pipe. The second protection cover is connected with the liquid medicine recycling pipe. Thespiral generator is adopted so that longitudinal impact flowing can be converted into three-dimensional flowing with a certain tangential speed, the jetted fluid has the longitudinal speed and also has radial and tangential component speed, rotary jet flow is formed, the jet flow entrainment and mixing are enhanced through washing liquid, the impact area is enlarged, the impact pressure intensityis reduced, and a more ideal wound surface washing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a structure of a rotating jet nozzle for a washing gun. Background technique [0002] The Disposable Irrigator is a disposable irrigation system that provides irrigation and suction, and can be used for wound debridement and surgical site cleaning. The traditional flushing device adopts the continuous jet flushing mode, which can control the flushing flow and pressure during flushing, so as to achieve the purpose of flushing; or adopts the pulse jet flushing mode, and the bacteria and foreign objects in the wound can be bounced to the tissue through the oscillation of the pulsed water flow. After detachment, a clear surgical field of view can be obtained after washing. [0003] The jet mode used in traditional irrigation guns is continuous jet or pulse jet, which has a large washing force. Although it can quickly wash the affected area, it is prone to splash a large ...

Problems solved by technology

[0003] The jet mode used in traditional irrigation guns is continuous jet or pulse jet, which has a large washing force. Although it can quickly wash the affected area, it is prone to splash a large amount of washing liquid. During clinical operations, the operator is often in a hurry. In time, the flushing fluid overflows and soaks the surgical area; in addition, the strong longitudinal impact produces high pressure on a single soft tissue, which easily causes the bacteria on the surface of the wound to migrate to the deep layer and is not easy to remove, thereby increasing the risk of surgical site infection

At the same time, the use of a large amount of flushing fluid also causes unnecessary waste
