Description

Multipurpose connector capable of being connected with three-cavity catheter

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a multipurpose connector that can be connected with three chamber catheters.

Background

Bladder irrigation (bladder irrigation) is a method in which a catheter is used to infuse a solution into the bladder and the infused liquid is then drained off by the siphon principle. The bladder irrigation methods include a closed irrigation method and an open irrigation method, and the most common bladder irrigation method at present is a closed continuous irrigation method by using a three-cavity balloon catheter, or sometimes a closed loop is constructed by using a two-cavity balloon catheter for continuous bladder irrigation, or closed intermittent bladder irrigation is adopted. The three-cavity balloon catheter has three cavities, namely a ventilation cavity, a drainage cavity and an irrigation cavity, compared with a common catheter, the three-cavity balloon catheter only has one more irrigation cavity at the tail end, the cavity and the drainage cavity are opened at the tip of a urinary catheter, when the bladder is irrigated, the irrigation fluid is connected with the irrigation cavity, and the irrigation fluid enters the bladder and then is discharged out of the body through the drainage cavity. Lack in clinical at present and wash chamber way assorted flushing joint, need the manual equipment washing unit of nursing staff, on the one hand interface connection insecure, take place the flush fluid seepage easily and pollute a bed unit, increase nurse's work load, easily pollute each interface in the on the other hand assembling process, arouse patient's urinary system infection. In recent years, importance is increasingly paid to the application of Intra-abdominal pressure (IAP) monitoring to critically ill patients, and after IAP is raised to a certain degree, adverse effects are generated on the functions of human organs, and multiple organ failure can be caused after the IAP is raised for a period of time. The measurement methods of IAP are divided into direct measurement and indirect measurement, and intravesical pressure is currently proposed as the first choice for indirect measurement of IAP in critically ill patients. When a scale with scales is used for measuring the openness pressure clinically, a plurality of objects are carried frequently, and the operation process is complicated; when the pressure transducer is used for carrying out closed pressure measurement, the connector of the pressure transducer is not matched with the catheter interface, and a pressure measurement device is assembled manually by nursing staff, so that the problems that an IAP pipeline has bubbles, the joint leaks, a connecting pipe bends and the like are easily caused, and the pressure measurement result is interfered.

Detailed Description

The following description of the preferred embodiments of the present invention will be given with reference to the accompanying drawings 1 to 3, and will make the functions and features of the present invention better understood.

Referring to fig. 1 to 3, a multipurpose connector capable of being connected with a three-cavity catheter according to an embodiment of the present invention includes a connector 1, a three-way pipe 2 and a three-way pipe switch 3; the three-way pipe 2 comprises a first connector 21 and two second connectors 22, and the connector 1 is fixedly connected with the first connector 21 in a sealing way; the three-way pipe switch 3 is arranged on the three-way pipe 2.

The joint 1 is in a frustum shape, and a plurality of annular stripes are formed on the outer surface of the joint 1.

The second interface 22 is matched with the inner diameter of the transfusion leather strip 7.

The connector is characterized by further comprising a connector cap 4, wherein the connector cap 4 is matched with the connector 1 in shape and detachably covered on the connector 1.

And two protective caps 5, wherein the protective caps 5 are detachably covered on the second interface 22.

In this embodiment, the maximum inner diameter of the joint 1 is 0.8 cm. The joint 1 is 3cm long.

At present, when the three-cavity catheter 6 is used for bladder irrigation or bladder pressure measurement, due to the lack of a matched irrigation interface, the transfusion leather strip 7 which is commonly used in clinic comprises a transfusion pump leather strip or a transfusion leather strip which is forcibly inserted into an irrigation lumen, and the lumen is easily polluted in the operation process; some medical staff usually insert the syringe needle of the transfusion system into the washing cavity directly for operation, and the washing branch pipe is damaged due to multiple insertions, and the risk of infection of patients is increased; even medical staff inserts the transfusion system needle into the ventilation tube cavity by mistake, and the normal saline in the air bag flows out along the direction of the transfusion system needle, so that the three-cavity catheter 6 slips. After the bladder irrigation is finished or the pressure measurement is finished, the tail end of the lumen is reversely folded and wrapped by gauze, so that the exposure risk is increased, and the urinary system infection of a patient is easily caused. When the urinary bladder with the two-cavity catheter is used for flushing, the flushing pipe is connected with the flushing fluid, one end of the Y-shaped pipe is connected with the flushing pipe, and the other two ends of the Y-shaped pipe are respectively connected with the catheter and the urine bag. In the operation process, the joint 1 needs to be repeatedly disengaged, so that the operation is complicated, the infection risk is increased, and the privacy part of a patient is often exposed, so that the patient feels dislike, repulses or dislikes.

When the multipurpose connector which can be connected with the three-cavity catheter is used, the connector 1 is matched with the catheter flushing interface of the three-cavity catheter 6 during bladder flushing, the interface can not fall off or loosen during flushing, and the flushing effect is good; the tail end of the device is provided with a second interface 22 of the three-way pipe 2 which can be matched with a common transfusion leather strip 7, and if the bladder flushing speed needs to be strictly controlled, the infusion pump can be used for accurately controlling the number of drops. When the bladder pressure is measured, the lumen is in a closed state, and the measurement result is more accurate; the three-way pipe 2 is connected with the pressure transducer, the joint 1 does not need to be disconnected when the measurement is needed, the three-way pipe switch 3 can be adjusted, and the physiological saline is injected from the other interface, so that the urinary system infection of the patient caused by repeated disconnection of the joint 1 is avoided. After the flushing or pressure measuring is finished, the device does not need to be taken down, and the three-way pipe 2 only needs to be adjusted to be in a closed state, so that the retrograde infection of the urinary system caused by the continuous opening of the pipe cavity is avoided. The device cost of manufacture is low, and is easy and simple to handle, and the nursing staff can accomplish the connection work that the bladder washed and the measurement of intra-abdominal pressure fast, saves nurse's time, alleviates nurse's work load.

The present invention has been described in detail with reference to the embodiments shown in the drawings, and those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details of the embodiments should not be construed as limitations of the invention, which are intended to be covered by the following claims.
