Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.
The utility model is given by figures 1 to 3, comprising a vertical hollow cylinder 1, wherein the left side and the right side of the upper end of the hollow cylinder 1 are fixed with horizontal cylinders 2, a three-way structure is formed between the hollow cylinder 1 and the cylinders 2, a sliding block 3 capable of sliding up and down is arranged in the hollow cylinder 1, an arc-shaped channel is arranged on the sliding block 3, and when the sliding block 3 is positioned at the upper end of the hollow cylinder 1, the left cylinder 2 is communicated with the cavity of the lower end of the hollow cylinder 1; when the sliding block 3 moves downwards and is separated from the cylinders 2, the lower end of the hollow cylinder 1 is closed, and the left cylinder 2 and the right cylinder 2 are communicated; the lower end of the hollow cylinder 1 and one end of the cylinder 2 far away from the hollow cylinder 1 are all provided with joint structures;
the joint structure comprises a conical sleeve 4, a folded edge 5 is arranged at one end, far away from the hollow tube, of the cylinder 2, an annular space is formed between the folded edge 5 and the outer side wall of the cylinder 2, the folded edge 5 is also arranged at the lower end of the hollow cylinder 1, an annular space is also formed between the folded edge 5 and the outer side wall of the hollow cylinder 1, one end, smaller in diameter, of the conical sleeve 4 is inserted into the annular space, and a sealing ring is sleeved on the conical sleeve 4.
In order to prevent the conical sleeve 4 from slipping with the hollow cylinder 1 or the cylinder 2, the inner side surface of the conical sleeve 4 is of an internal thread structure, the outer side surface of the lower end of the hollow cylinder 1 is of an external thread structure, and the outer side wall of one end of the cylinder 2 far away from the hollow cylinder 1 is of an external thread structure.
In order to control the sampling amount, the upper end of the sliding block is provided with a vertical rod 6, the upper end of the vertical rod 6 penetrates through the upper end of the hollow cylinder 1, and a pressure spring is connected between the sliding block and the upper end of the hollow cylinder 1.
It is worth noting that in this scheme, adopt hem 5 to promote the sealing washer along the outer disc of circular cone cover 4 for the external diameter of sealing washer increases gradually, and then hugs closely with the inner wall of the pipeline that needs to communicate, finally forms seal structure, simultaneously because the relative frictional force between sealing washer and the pipeline is great, as long as hem 5 is propped up the sealing washer and makes it can not remove to the little, then the joint position is can not become flexible.
Before use, the cylinder 2 at the left end is communicated with a catheter, the cylinder 2 at the right end is communicated with a urine bag, the lower end of the hollow cylinder 1 is communicated with a sampling container, during installation, a pipeline to be communicated is sleeved on the conical surface of the conical sleeve 4, then the conical sleeve 4 is screwed, the conical sleeve 4 is gradually inserted into an annular space corresponding to the conical sleeve, the sealing ring on the conical sleeve 4 is pushed to the big end of the conical sleeve 4 by the corresponding folded edge 5, the outer edge diameter of the sealing ring is gradually increased until the sealing ring is tightly attached to the inner side wall of the pipeline, and the interface action is completed. When the urine sampling device is used, an index finger and a middle finger are respectively arranged on two sides of the hollow cylinder 1, the thumb presses the vertical rod 6 to enable the sliding block to be completely separated from the cylinder 2, at the moment, the lower section of the hollow cylinder 1 is closed, urine enters the left cylinder 2 from the catheter, then enters the right urine bag through the right cylinder 2 along the horizontal direction, after a period of time, the front section of urine enters the urine bag, at the moment, the thumb can be loosened, the pressure spring moves upwards and returns to the original state, at the moment, the right cylinder 2 is closed, the hollow cylinder 1 is communicated with the left cylinder 2 through a channel, at the moment, the urine taken out is representative middle-section urine, after the sampling amount is enough, the vertical rod 6 is pressed to enable the two cylinders 2 to be communicated until the urine is completely in a closed state, and the thumb is loosened.
In the process, all operations are completed by one hand, and the method is convenient and quick. When the pipe needs to be removed, the conical sleeve 4 is only required to be reversely screwed, so that the folded edge 5 is separated from the sealing ring, and the pipe is slightly pulled at the moment, so that the splitting action can be completed.
The utility model has smart structure, can store the front section urine and the middle section urine separately, can sample according to the needs, and is convenient to mount and dismount.
