Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The purpose of this embodiment is to provide a catheter, through set up the marker on the pipe of catheter for show the relative position between pipe and the human body, supply medical personnel to observe, and then can effectively avoid medical personnel to miss the problem that the inspection catheter deviates from.

Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to fig. 1-2, schematic structural views of urinary catheters in some exemplary embodiments are shown. The catheter provided by the embodiment comprises a catheter 3 with a drainage cavity 1 and an air transmission cavity 2, wherein the front part of the catheter 3 is provided with an air bag 4 communicated with the air transmission cavity 2 and used for fixing the catheter in a human body, and a first opening 5 for communicating the drainage cavity 1 with the outer space of the catheter 3 is arranged between the front end part of the catheter 3 and the air bag 4 and used for discharging urine in the human body to the drainage cavity 1; the catheter 3 is provided with a marker for displaying the relative position between the catheter 3 and the human body. So set up, the one end that is provided with gasbag 4 with the pipe 3 of this catheter inserts to the internal back of patient, and the marker can demonstrate the relative position between pipe 3 and the human body, in the use, if pipe 3 changes in the position of human inside, also can change at the marker that human outside observed, so medical personnel can in time discover the position change of catheter, avoid missing the problem that the inspection catheter deviates from.

It should be noted that, a plurality of drainage lumens 1 may be provided, and each of the drainage lumens may be used for injecting different drugs into the catheter. When the quantity of drainage chamber 1 is two, a drainage chamber 1 is used for the catheterization, and another drainage chamber 1 is used for injecting the medicament to bladder inside, when the human body was kept somewhere for a long time at the catheter, can be through this drainage chamber 1 to bladder inside injection medicament in order to wash the bladder.

In a preferred embodiment, the markers may be graduation marks and font marks 6, and the graduation marks and font marks 6 are distributed along the length direction of the catheter 3 from the front end portion of the catheter 3. After the catheter is inserted into the body of a patient, medical staff can record and read corresponding data, and in the using process, if the position of the catheter 3 in the human body is changed, the data read by the medical staff can be changed, so that the data are visual and convenient to check; through the data contrast of quantization, medical personnel can directly perceivedly, in time discover whether the position of catheter changes to in time avoid effectively missing the problem that the catheter deviates from.

It should be noted that the above-mentioned markers can also be in other forms besides the scale lines and the font marks 6, such as: and (4) color marking. The colour markings may comprise a green, yellow and red segment marked on the catheter 3 and distributed in the direction from the rear of the catheter 3 to the front of the catheter 3, in use, the green segment only being visible from outside the body in a normal safe condition; when a yellow segment is observed in vitro, the catheter is about to fall out of the body of the patient; when a red colored segment is observed in vitro, it indicates that the catheter is in a detached state.

In implementation, in order to reduce the friction coefficient between the catheter 3 and the human body and reduce the discomfort brought to the patient, the scale marks and the font marks 6 are arranged on the inner side wall of the catheter 3.

Further, the outer side wall of the catheter 3 may also be provided with a hydrophilic coating. Before using, soak the lateral wall of pipe 3 of catheter, hydrophilic coating meets water and can form lubricated membrane fast after, makes 3 surfaces of pipe obtain abundant efficient lubrication, reduces the friction between pipe 3 and the human body, reduces patient's uncomfortable sense.

As an alternative embodiment, a cleaning cavity 7 is further arranged in the catheter 3, a second opening 8 for communicating the cleaning cavity 7 with the space outside the catheter 3 is arranged on the catheter 3, and the second opening 8 is positioned at the opposite side of the balloon 4 on which the first opening 5 is arranged. Water is injected or detergent is injected through the cleaning cavity 7, the water or the detergent in the cleaning cavity 7 slowly seeps out from the second opening 8, the catheter 3 below the air bag 4, namely the catheter 3 on the side opposite to the side provided with the first opening 5, is cleaned, and retrograde infection caused by bacteria entering the body of a patient along the outer side wall of the catheter 3 is avoided. Above-mentioned second opening 8 can set up two, and symmetrical arrangement is in the both sides of pipe 3, makes water or sanitizer from wasing in the chamber 7 ooze simultaneously gradually from two second openings 8 respectively, guarantees that the lateral wall homoenergetic of whole pipe 3 is washd, has guaranteed that the catheter outer wall does not have the bacterium and has got into.

In this embodiment, the two first openings 5 are symmetrically disposed on the conduit 3 along the circumferential direction of the conduit 3, so as to facilitate the discharge of urine.

In order to facilitate the insertion of the catheter and reduce the discomfort of a patient, the diameter of the catheter 3 of the catheter is set to be 6-8 mm. The material of the conduit 3 may be polyvinyl chloride, silica gel or polyurethane, preferably polyurethane.

In implementation, a urine bag connected with the drainage cavity 1 is also connected and arranged at the rear end part of the catheter 3 and is used for temporarily storing urine. Through threaded connection between pipe 3 and the urine bag, can be provided with the internal thread in the drainage chamber 1 position department of pipe 3 back end portion, be provided with the hollow joint pin that has the external screw thread on the urine bag, pipe 3 is connected through internal thread and external screw thread with the urine bag. After the urine in the urine bag reaches a certain amount, the urine bag can be unscrewed from the catheter 3, so that the urine stored in the urine bag is discharged through the cavity of the hollow connecting column.

It should be noted that the graduation marks and the lettering 6 shown in fig. 1 are only an illustration of the structure of the marker, and the lettering shown in the figure does not represent the length of the catheter, and the overall length of the catheter cannot be estimated by scale.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
