Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

As shown in fig. 1 to 4, an improved drainage bag according to an embodiment of the present application includes a bag body 1 and a drainage tube 2 mounted on the bag body 1, wherein an end portion of the drainage tube 2 is inserted into a patient, and a effusion flows into the bag body 1 along the drainage tube 2, wherein a regulator is configured on the drainage tube 2 for regulating a flow rate of the drainage tube 2, and the above disclosure is related art, and the distinguishing technical features of the present application are as follows: the liquid discharge tube 3 is arranged on the bag body 1, a part of tube body structure of the liquid discharge tube 3 is positioned in the bag body 1, the end part of the liquid discharge tube 3 positioned in the bag body 1 is in a sealing design, the outer peripheral side of the contact part of the liquid discharge tube 3 and the interior of the bag body 1 is provided with a liquid discharge channel 6, namely, liquid in the bag body 1 is discharged into the liquid discharge tube 3 through the liquid discharge channel 6, the liquid discharge tube 3 is connected with a liquid discharge tube 7 through a spring 10, one end of the liquid discharge tube 7 penetrates through one end of the liquid discharge tube 3 positioned outside the bag body 1, when the spring 10 is in an initial state, the liquid discharge channel 6 is blocked by the outer peripheral side of the liquid discharge tube 7, the stability of the liquid discharge tube 7 is kept by the spring 10, and the end part of the liquid discharge tube 3 positioned in the bag body 1 is in a sealing design, so that the liquid discharge tube 7 is not influenced by the liquid gravity in the bag body 1, the liquid discharge tube 7 can keep effective stability under the action of the spring 10, and when the spring 10 is in a compressed state, the liquid discharge tube 7 releases the blocking of the liquid discharge channel 6, and the end part of the liquid discharge tube 7 is detachably connected with the sealing cover 4;

According to the disclosure, under normal conditions, the liquid outlet pipe 7 seals the liquid outlet channel 6, the bag body 1 completes liquid collection, when liquid is required to be discharged, the sealing cover 4 is firstly separated from the liquid outlet pipe 7, at the moment, the liquid cannot be discharged, then the liquid outlet pipe 7 is pulled to drive the liquid outlet pipe 7 to move, the liquid outlet pipe 7 does not shield the liquid outlet channel 6 any more, then the liquid in the bag body 1 enters the liquid outlet pipe 3 through the liquid outlet channel 6, at the moment, the end of the liquid outlet pipe 7 in the liquid outlet pipe 3 is attached to the inner wall of the liquid outlet pipe 3, the liquid entering the liquid outlet pipe 3 finally enters the liquid outlet pipe 7, then is discharged through the liquid outlet pipe 7, after the liquid in the bag body 1 is discharged, the liquid outlet pipe 7 is reset, under the thrust of the spring 10, the liquid outlet pipe 7 is enabled to continuously seal the liquid outlet channel 6, and then the sealing cover 4 is connected with the liquid outlet pipe 7;

The difference between the technical scheme and the prior art is that the liquid outlet pipe 7 plays a role in transferring, liquid is filled in the liquid outlet pipe 3 at present when liquid is discharged, when the sealing cover 4 is opened, the liquid directly flows out, and when the sealing cover 4 is opened, the liquid does not flow out, but is driven to move by holding the liquid outlet pipe 7, and then the liquid outlet pipe 7 is used for discharging liquid, so that the situation of being stained with the liquid is avoided to a great extent, and convenience is provided for liquid discharging work.

As shown in fig. 4, in some embodiments, the inner peripheral side of the liquid discharge pipe 3 is configured with a step ring plate 8, a sealing ring 9 is installed in a step groove of the step ring plate 8, one end of the liquid discharge pipe 7 slides through the step ring plate 8, a joint surface is configured on the liquid discharge pipe 7 and embedded into the step groove, the liquid discharge pipe 7 moves in the liquid discharge pipe 3, and the liquid needs to be discharged through the liquid discharge pipe 7, so that the tightness between the liquid discharge pipe 7 and the liquid discharge pipe 3 needs to be ensured, wherein a first part of the liquid discharge pipe 7 is configured above the step ring plate 8, the part of the structure can be regarded as a ring frame, the ring frame contacts with the inner wall of the liquid discharge pipe 3 and is used for receiving the liquid, when the liquid discharge pipe 7 moves to contact with the step ring plate 8, the sealing ring 9 is extruded to improve the tightness between the joint surface of the liquid discharge pipe 7 and the step ring plate 8, thus improving the tightness of the joint of the liquid discharge pipe 7 and the step ring plate 8, and the step ring plate 8 can also play a positioning role in providing a prompting role for a user that indicates that the liquid discharge pipe 7 moves to a proper position.

As shown in fig. 4, in some embodiments, the outer peripheral side of the liquid outlet pipe 7 is configured with a sliding block 12, the inner peripheral side of the liquid outlet pipe 3 is provided with a guiding block 11 along the axial direction thereof, the sliding block 12 is slidably sleeved on the guiding block 11, and the purpose of limiting and guiding the movement of the liquid outlet pipe 7 is achieved under the cooperation of the sliding block 12 and the guiding block 11, so that the liquid outlet pipe 7 can only perform axial movement without circumferential movement.

As shown in fig. 4, in some embodiments, the guide block 11 and the slide block 12 are both located on one surface of the step ring plate 8, which avoids the liquid discharge channel 6, so that the staggered structural design reduces the contact gap between the liquid discharge pipe 7 and the liquid discharge pipe 3, and avoids the excessive influence on the tightness due to the fact that the liquid directly enters the liquid discharge pipe 7 and cannot pass through the space of the liquid discharge pipe 3 below the step ring plate 8, so that the tightness is ensured.

In some embodiments, as shown in fig. 4, one end of the spring 10 is connected to the drain pipe 3, and the other end is connected to the slider 12, when the slider 12 moves synchronously with the drain pipe 7, the slider 12 presses the spring 10, so that the spring 10 is forced to generate an acting force for pushing the slider 12 to reset, and in a normal state, the stability of the whole drain pipe 7 is ensured by the spring 10.

As shown in fig. 4, in some embodiments, a reducing pipe 13 is configured in the middle of the liquid outlet pipe 7, the reducing pipe 13 aims to increase fluidity of the liquid in a converging way, and secondly, the liquid jet caused by oversized end pipe orifice is avoided, and the liquid is formed into small strands to be discharged under the cooperation of the reducing pipe 13.

As shown in fig. 4, in some embodiments, the cover 4 is in threaded connection with the liquid outlet pipe 7, so that the disassembling operation of the cover 4 is conveniently completed, and the tightness between the cover 4 and the liquid outlet pipe 7 after being installed is ensured.

As shown in fig. 1, in some embodiments, two lugs 5 are configured on the bag 1, and the purpose of the lugs 5 is to fit pins or other structures to mount the bag 1 on a hospital bed or clothing, so that the bag 1 is in a limited state.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
