DETAILED DESCRIPTION
[0021] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figures 1 to 5 As shown, a drainage tube with adjustable drainage speed includes an adjustment seat 1, an adjustment roller 2 and a blocking mechanism; the adjustment roller 2 is rollingly arranged in the adjustment seat 1, and a drainage tube 7 passes through the adjustment seat 1; avoidance openings 11 are provided at both ends of the adjustment seat 1, and a slide groove 12 is provided in the middle of the adjustment seat 1; the drainage tube 7 passes through the avoidance openings 11 on both sides; guide grooves 13 are provided on both sides of the slide groove 12, and the projections of the guide groove 13 on the vertical and horizontal planes are at a certain angle; the two ends of the adjustment roller 2 are rollingly arranged in the guide groove 13; by rolling the adjustment roller 2 in the guide groove 13, the channel size of the drainage tube 7 can be conveniently adjusted, thereby realizing precise control of the drainage speed. This design enables doctors or nursing staff to flexibly adjust the drainage speed according to different conditions and drainage needs, thereby improving the treatment effect and the comfort of patients.
[0023] The blocking mechanism includes a blocking block 3, a buckle block 4, a first spring 41 and a handle 42; a slot 14 is provided at the top of the adjusting seat 1; the slot 14 is connected to the avoidance opening 11; a slot 141 is provided on one side of the slot 14 located at the top of the adjusting seat 1; the blocking block 3 is slidably arranged in the slot 14; the buckle block 4 is arranged in the slot 141; one end of the first spring 41 is connected to the bottom of the slot 141, and the other end is connected to the buckle block 4; one end of the handle 42 is connected to the buckle block 4, and the other end passes through the bottom of the buckle slot and extends to the top of the adjusting seat 1.
[0024] By setting up a blocking mechanism, when the drainage tube 7 needs to stop flowing, the blocking function can be achieved quickly and effectively, and the position of the blocking block 3 can be locked by the buckle assembly to ensure that the blocking block 3 can be stably maintained in the blocking position after insertion, and will not be easily moved or loosened due to external factors or activities in the patient's body.
[0025] like Figure 4 and Figure 5 As shown, reset components are arranged on both sides of the blocking block 3, and the reset components include a reset block 5 and a second spring 51; reset grooves 142 are arranged on both sides of the slot 14; the reset block 5 is slidably arranged in the reset groove 142; one end of the second spring 51 is connected to the bottom of the reset groove 142, and the other end is connected to the reset block 5.
[0026] By setting up a reset component, when it is necessary to release the blocked state of the drainage tube 7, the buckle block 4 is released from the blocking block 3 by pulling the handle 42, and then the elastic force of the second spring 51 is cooperated to make the blockage quickly return to the initial position, so that the drainage tube 7 is unobstructed again.
[0027] like Figure 5 As shown, a push handle 6 is arranged above the blocking block 3 , and a receiving hole 61 is opened on the push handle 6 ; the size of the receiving hole 61 is adapted to the buckle block 4 .
[0028] The cooperation between the handle 6 and the receiving hole 61 facilitates the quick blocking and opening of the blocking block 3, ensuring that the buckle block 4 can be stably inserted into the receiving hole 61, thereby firmly fixing the position of the blocking block 3. This fixing method not only ensures the stability of the drainage tube 7 in the blocking state, but also effectively prevents the blocking block 3 from accidentally moving due to external force.
[0029] The bottom of the blocking block 3 is provided with a chamfer.
[0030] By providing the chamfer, the blocking block 3 can better fit with the outer peripheral wall of the drainage tube 7, thereby improving the blocking effect.
[0031] like Figure 2 As shown, a friction block 21 is arranged on the outer peripheral wall of the adjusting roller 2 .
[0032] By providing the friction block 21, the adjusting roller 2 is more stable when rolling and is not prone to slippage or shaking. This helps to ensure the accuracy and reliability of the adjusting roller 2 during the adjustment process, thereby achieving stable control of the drainage speed.
[0033] The working principle of the utility model is as follows: first, the drainage tube 7 is passed through the inside of the adjustment seat 1, and the adjustment roller 2 is rolled in the slide groove 12 and the guide groove 13 in the adjustment seat 1. The projections of these guide grooves 13 on the vertical and horizontal planes are at a certain angle, allowing the adjustment roller 2 to change its position in the guide groove 13 when rolling, thereby changing the channel size of the drainage tube 7 in the adjustment seat 1. When the drainage speed needs to be adjusted, the adjustment roller 2 can be operated to make it roll in the guide groove 13, thereby achieving precise adjustment of the channel width of the drainage tube 7.
[0034] On the other hand, the blocking mechanism is designed so that when it is necessary to stop drainage, the blocking block 3 is driven to slide in the slot 14 by pressing the handle 6, and the flow of liquid in the drainage tube 7 is blocked by the chamfered setting at the bottom by moving downward into the drainage tube 7. During the pressing process, the reset blocks 5 on both sides of the blocking block 3 compress the second spring 51. At the same time, during the pressing process, the position of the accommodating hole 61 on the handle 6 moves to the same horizontal plane as the buckle block 4. The buckle block 4 extends into the accommodating hole 61 through the elastic force of the first spring 41 to complete the locking of the blocking block 3. The locked position needs to ensure that the bottom of the blocking block 3 is introduced to complete the blocking of the drainage tube 7. When it is necessary to release the blocking, just pull the handle 42 to release the buckle block 4 from the slot 141, and then the reset blocks 5 on both sides of the blocking block 3 drive the blocking block 3 to automatically reset under the reverse force of the second spring 51 to reopen the drainage channel.
[0035] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
