As shown in fig. 1-6, a quick drainage device for ICU nursing comprises a collecting box 1; the upper end of the collecting box 1 is communicated with a drainage tube 2; an anti-blocking device is arranged on the drainage tube 2; the upper end of the collecting box 1 is provided with a negative pressure pump 3; the air exhaust end of the negative pressure pump 3 is communicated with an air exhaust pipe 4; the other end of the exhaust pipe 4 is communicated with the collecting box 1; the anti-blocking device comprises a tube head 5 communicated with the top end of the drainage tube 2; the left end of the tube head 5 is fixedly connected with an elastic sleeve 6; the elastic sleeve 6 is arranged at the left part in the pipe head 5; the left end of the elastic sleeve 6 is in butt joint with the left end of the tube head 5; the outer side of the right part of the elastic sleeve 6 is fixedly sleeved and connected with an electromagnetic coil 7; the electromagnetic coil 7 is sealed in the right pipe wall of the elastic sleeve 6; the right part in the pipe head 5 is provided with a mounting column 8; the mounting column 8 is fixedly connected with the inner wall of the tube head 5 through a support rod 9; the right end of the mounting column 8 is provided with a permanent magnet 10; a piercing rod 11 is arranged at the left end of the mounting column 8; barbs 12 are uniformly distributed on the side surface of the piercing rod 11; an air pressure sensor module 13 is arranged in the collecting box 1; the signal output end of the air pressure sensor module 13 is connected with a processor; the output end of the processor is connected with the negative pressure pump 3 and the control circuit of the electromagnetic coil 7; an indicator light 14 is arranged at the upper end of the collecting box 1; the output end of the processor is connected with the control circuit of the indicator light 14; the mounting column 8 is in a circular truncated cone shape, and the left part of the mounting column 8 is in sealing insertion fit with the right part of the elastic sleeve 6; the surface of the tube head 5 and the surface of the elastic sleeve 6 are coated with blood anticoagulant; a pressure stabilizing valve 15 is arranged in the top end wall of the collecting box 1.

When the negative pressure suction type drainage tube is used, the drainage tube 2 and the tube head 5 are inserted into the position of effusion of a patient, the outside is bonded and fixed, and the like, the negative pressure pump 3 is started, the negative pressure pump 3 enables the inside of the collection box 1 to form a negative pressure state, and the effusion is extracted by utilizing the negative pressure. The negative pressure pump 3 works stably, and when the effusion is extracted to be in a stable state, the negative pressure state in the collecting box 1 is also stable. The middle part of the elastic sleeve 6 is a drainage inlet, and the left cambered surface of the elastic sleeve 6 is an inlet end surface. When drainage import or import terminal surface were blockked up, caused the hindrance of hydrops extraction, then the inside negative pressure of collecting box 1 risees, and atmospheric pressure sensor module 13 can detect the short sight of atmospheric pressure and continuously descend, and the treater judgement is the tip jam this moment. The processor controls the electromagnetic coil 7 to change magnetic poles at a certain frequency, so that the electromagnetic coil 7 and the permanent magnet 10 are attracted or repelled to form a repeated motion with a certain frequency and amplitude, the left part of the elastic sleeve 6 forms a crawler-type rolling unfolding movement, the end part blockage treatment is realized, and the blockage is avoided.

As shown in fig. 2 and 5, when the tube head 5 enters the human body, if the passage space is smaller, the electromagnetic coil 7 can be opened to work, the human tissue is expanded by utilizing the rolling expansion degree when the elastic sleeve 6 moves towards the left part (similar to the anticlockwise rotation process of the crawler, the rolling is expanded from inside to outside, the expansion friction resistance is smaller, the rolling is different from the traditional direct pushing, the rolling is easier to expand the human tissue at the left side, the tissue after one or more times of expansion is easier to enter), the rolling expansion of the human tissue when the elastic sleeve 6 moves towards the left is only utilized in the embodiment, and the rolling expansion is irrelevant with the rightward retraction. After entering the accumulated liquid part, when the blockage is automatically judged, the blockage is processed.

In the process of blocking treatment, the processor controls the electromagnetic coil 7 to work, in the process of repeatedly moving the elastic sleeve 6, the inlet end face is always an arc surface and repeatedly moves left and right, in the moving process, the coagulum blocked on the inlet end face and the like are repeatedly pushed away, under the action of suction drainage, the coagulum moves to the inlet, and in the moving process, the coagulum can possibly rotate, so that the coagulum can smoothly enter the elastic sleeve 6 and be extracted; if the diameter is larger, the coagulation block can not be smoothly inserted, in the repeated moving and rotating process, the suction surface of the coagulation block is continuously changed by the inlet, the reverse flushing of the coagulation block and drainage is performed, and the like, the coagulation block can be changed, and partial extraction is easier until the whole coagulation block is extracted;

as shown in fig. 4 and 5, when the condensation block is blocked in the elastic sleeve 6, the condensation block can be driven to move by the left and right movement of the elastic sleeve 6, and in the moving process, the condensation block can impact with the puncture rod 11 and the barb 12 and can be extracted smoothly by being forcedly crushed; and because the elasticity of elastic sleeve 6 self, when the elastic sleeve 6 right-hand member moved left, then can cause the deformation of left part, this deformation changes the import diameter size, extrudees the coagulum that blocks up, can reduce the diameter of coagulum, is convenient for break away from the extraction.

In the process of blockage treatment, the device can be controlled by a timer module or manually, and works for a short time, such as five seconds and the like after being sequentially started, and does not need too long time due to high-frequency action, so that the next working period can be immediately started when the negative pressure rises even if the negative pressure is not solved in one working period.

According to the use requirement and medical safety consideration, the control frequency of the electromagnetic coil 7 is selected to ensure that the movement reversing frequency and amplitude of the elastic sleeve 6 are within a safe range, for example, high frequency and low amplitude are adopted, the frequency of changing left and right movement is improved, the effect of blocking treatment or rolling unfolding can be enhanced, and safety in some parts can be ensured by low-amplitude movement, so that injury is avoided.

As shown in fig. 5, in the present invention, the left end of the elastic sleeve 6 is in sealed butt joint with the left end of the tube head 5, which is completely different from the conventional telescopic variation, and the stroke of the right end of the elastic sleeve 6 is greater than the stroke variation of the inlet end face, which is roughly twice the relationship (known from the use principle of the movable pulley), so that the right end of the elastic sleeve 6 can perform a relatively large stroke to drive the blocked coagulated block to effectively move, and the stroke of the inlet end face is relatively small, thereby avoiding damage caused by an excessively large amplitude.

As shown in figure 4, when hydrops extraction ended or stopped, treater control solenoid 7 utilized magnetism suction, with the right-hand member port and the 8 butt joints of erection column of elastic sleeve 6, and erection column 8 adopts round platform shape, and the butt joint of being convenient for is sealed, then can follow the shutoff that the tip realized the drainage, can avoid the hydrops refluence in drainage tube 2, and it is better to prevent the refluence effect.
