Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a postoperative exudate drainage device. Background Art
[0002] After minimally invasive, interventional or other minimally invasive surgeries, a drainage device is usually connected to the wound site of the patient to drain the exudate from the patient's body. The drainage device generally includes a first catheter connected to a drainage bag and a second catheter usually fixed to the patient's body. The first catheter is connected to the second catheter through a joint, and the exudate enters the first catheter through the second catheter and is then discharged into the drainage bag.
[0003] The drainage bag needs to be replaced according to the discharge of the patient's exudate. When replacing it, the nursing staff needs to clamp the second catheter with medical clamping scissors to prevent the exudate from continuing to flow out, shake and clean the residual liquid in the first catheter and the second catheter, and then clamp the first catheter with a pipeline clamp, and then disinfect the connection position between the joint and the second catheter. After a series of treatments, the new first catheter and the plug are inserted into the second catheter with force to complete the replacement of the drainage bag. The process is relatively complicated and requires the assistance of clamping scissors;
[0004] In the prior art, the plug and the second catheter are stably connected by interference fit through the elasticity of the second catheter itself, but the interference fit requires greater force when plugging in and out, especially after the second catheter has been used for a long time, when the plug of the second catheter expands due to fatigue life, the difficulty and stability of plugging in will increase, which is not friendly to the group of nursing staff, most of whom are women. Therefore, based on this situation, a postoperative exudate drainage device needs to be designed. Utility Model Content
[0005] The utility model aims to overcome the deficiencies of the prior art and provide a postoperative exudate drainage device, which changes the traditional interface plug-in interference fit connection to a circumferential fit connection, thereby reducing the difficulty of operation.
[0006] The utility model solves the technical problem by adopting the following technical solutions:

[0009] Preferably, the sleeve is constructed with a sliding rod, which extends axially in the second catheter, and also includes a locking piece, which is slidably connected to the sliding rod and abuts against the outer surface of the clamping part so that the locking piece can adjust the clamping angle of the clamping part when the locking piece slides axially in the second catheter.
[0010] Preferably, the slide bar is provided with a positioning portion, and the locking member is correspondingly provided with a clamping portion, and the clamping portion is embedded in the positioning portion to achieve locking of the locking member.
[0011] Preferably, the locking member is formed with a contact protrusion on a side facing the clamping portion.
[0012] Preferably, the sliding rod is structured with a limiting protrusion.
[0013] Preferably, the positioning portion is grooved from one side of the slide bar to the other side, and in the circumferential direction of the second conduit, the groove depth is 1 / 5-3 / 4 of the slide bar.
[0014] Preferably, the positioning portion includes a first positioning groove and a second positioning groove which are axially arranged on the slide rod.
[0015] Preferably, it further comprises a pipeline clamp, which is movably sleeved on the first conduit, and the pipeline clamp is detachably connected to the sleeve. In the connected state, the joint limits the pipeline clamp so that the pipeline clamp cannot be separated from the joint.
[0016] The advantages and positive effects of the utility model are:

The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0037] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:
[0038] Embodiment 1:
[0039] A postoperative exudate drainage device includes: a first catheter 100, one end of which is connected to a joint 110; a second catheter 200, which is connected to the first catheter 100 through the joint 110; a sleeve 300, which is movably sleeved on the second catheter 200, and the sleeve 300 is configured with an elastic clamping portion 310 in the axial direction of the second catheter 200, and the clamping portion 310 extends circumferentially of the second catheter 200 to pressurize the second catheter 200 circumferentially.
[0040] like Figure 1 As shown, the right end of the first catheter 100 is a connector 110, and the other end of the first catheter 100 is connected to the drainage bag; the connector 110 is generally a conical pagoda connector 110, which can be inserted into the left end interface of the second catheter 200, thereby connecting the first catheter 100 and the second catheter 200;
[0041] The sleeve 300 is annular and is sleeved on the outside of the second catheter 200. It can slide on the second catheter 200. In the axial direction of the second catheter 200, a clamping portion 310 is constructed on the right side of the sleeve 300. The clamping portion 310 includes a first elastic arm 311 and a second elastic arm 312 symmetrically arranged up and down. The first elastic arm 311 and the second elastic arm 312 form an angle in a natural state. The first elastic arm 311 and the second elastic arm 312 extend in the axial direction of the second catheter 200, generally 60-80°, to ensure the contact area between the first elastic arm 311, the second elastic arm 312 and the second catheter 200.
[0042] In the normal connection state, the plug is easily inserted into the left end interface of the second catheter 200. The nursing staff only needs to move the position of the sleeve 300 so that the clamping position of the first elastic arm 311 and the second elastic arm 312 overlaps with the position of the connector 110. The second catheter 200 is located between the clamping portion 310 and the connector 110, and the clamping portion 310 can fix the second catheter 200 circumferentially.
[0043] By adding circumferential fixation of the clamping portion 310 of the sleeve 300 to the traditional connector 110, the stability of the connection between the connector 110 and the second catheter 200 can be improved; further, the taper of the connector 110 is changed at the production and assembly end, so that the connector 110 is easy to insert into the second catheter 200. During insertion, there is no need for the connector 110 and the second catheter 200 to achieve a large interference fit, which is convenient for medical staff to insert and remove. Afterwards, by moving the position of the sleeve 300, circumferential fixation can be achieved to achieve better stability.
[0044] like Figure 2 As shown, the sleeve 300 extends axially of the second catheter 200 to form a ring with a certain width, providing a finger gripping position for the nursing staff. In some embodiments, ribs may be provided on its outer surface to increase friction;
[0045] like Figure 2 As shown, the inner side surfaces of the right ends of the first elastic arm 311 and the second elastic arm 312 are both configured with a planar protrusion 310 a to increase the contact area between the first elastic arm 311 , the second elastic arm 312 and the second conduit 200 .
[0046] like Figure 2 As shown, there are two sliding rods 320 corresponding to each other in the front and rear, and the two sliding rods 320 are arranged in parallel with the first elastic arm 311 and the second elastic arm 312. The sliding rod 320 extends in the axial direction of the second catheter 200 and is longer than the first elastic arm 311 / the second elastic arm 312;
[0047] like Figure 2As shown, each slide bar 320 has a positioning portion, and the positioning portion includes a first positioning groove 321. The first positioning groove 321 on the front side is grooved downward from the upper side of the slide bar 320 in the circumferential direction of the second conduit 200, and has forward and upward notches to form an inner groove surface 320a and a bottom groove surface. The depth of the groove is 1 / 5-3 / 4 of the depth of the slide bar 320 to avoid transitional grooves that reduce the strength of the slide bar 320. It can be understood that the slide bar 320 on the rear side is provided with a positioning portion, and the positioning portion on the rear slide bar 320 is centrally symmetrical with the positioning portion of the front slide bar 320.
[0048] like Figure 2 As shown, at the right end of the slide bar 320, a ring body 350 is also constructed to prevent the locking member 400 from being separated. The ring body 350 is made of a flexible material as a whole or partially, so as to utilize the deformable characteristics of the slide bar 320 to install the locking member 400;
[0049] like Figure 2 As shown, a limiting protrusion 330 is further provided at the left end of the first positioning groove 321 to prevent the locking member 400 from excessive movement. When the nursing staff encounters resistance when moving the locking member 400, the locking member 400 can be rotated and locked.
[0050] like Figure 3 and Figure 4 As shown, the locking member 400 is annular as a whole, and is symmetrically constructed with a protruding sliding unit, and the sliding unit cooperates with the sliding rod 320 to form a sliding connection; the locking member 400 includes a first inner ring surface 400a formed on the sliding unit, and the inner diameter of the first inner ring surface 400a is close to the outer diameter of the circumference formed by the two sliding rods 320. Figure 1 Under normal circumstances, the first inner annular surface 400a of the locking member 400 contacts the outer side surface of the sliding rod 320, so that the locking member 400 slides on the sliding rod 320;
[0051] like Figure 3 and Figure 4 As shown, the locking member 400 further includes a second inner annular surface 411, and the inner diameter of the second inner annular surface 411 is smaller than that of the first inner annular surface 400a. Figure 2-4 , the inner diameter of the second inner annular surface 411 is close to the outer diameter of the circumference formed by the inner groove surfaces 320a of the two sliding bars 320, so that the second inner annular surface 411 can contact the inner groove surfaces 320a;
[0052] The transition position from the first inner annular surface 400a to the second inner annular surface 411 is the clamping portion 410 of the locking member 400. By utilizing the structural change, the clamping portion 410 can be matched with the positioning portion.
[0053] like Figure 3 and Figure 4As shown, on the inner side of the first inner annular surface 400a, the locking piece 400 is further constructed with a contact protrusion 420, and the inner side of the contact protrusion 420 is a third inner annular surface 421, and the inner diameter of the third inner annular surface 421 is smaller than the inner diameter of the second inner annular surface 411. The third inner annular surface 421 abuts against the outer surfaces of the first elastic arm 311 and the second elastic arm 312, which is conducive to causing the clamping portion 310 to deform and can cooperate with the ring body 350. After being assembled to the second catheter 200, the locking piece 400 will not fall off.
[0054] refer to Figure 1 and Figure 4 and Figure 5 After the connector 110 is inserted into the second catheter 200, the locking member 400 is moved to the left. When the locking member 400 contacts the limiting protrusion 330, the nursing staff can obviously feel the resistance and rotate the locking member 400 so that the clamping portion 410 of the locking member 400 enters the first positioning groove 321. At this time, the second inner annular surface 411 is close to the inner groove surface 320a, and the movement of the locking member 400 is limited by the first positioning groove 321. The first elastic arm 311 and the second elastic arm 312 are in contact with the third inner annular surface 421 of the locking member 400, and the rotation of the locking member 400 is limited by the friction force to achieve the locking function.
[0055] like Figure 6 As shown, it also includes a pipeline clamp 500, which is movably sleeved on the first catheter 100. The pipeline clamp 500 is detachably connected to the sleeve 300. In the connected state, the connector 110 limits the pipeline clamp 500 so that the pipeline clamp 500 cannot be separated from the connector 110.
[0056] Specifically, Figure 1 As shown, the main body of the pipeline clamp 500 is the prior art, and specifically, the internal circular opening 510 is slidably matched with the first conduit 100. When necessary, the first conduit 100 is closed through the gap 520 communicating with the opening 510, which will not be described in detail.
[0057] like Figure 1 and Figure 6 As shown, a buckle is provided on the right side of the pipeline clamp 500, and a bayonet 340 is formed on the left side of the sleeve 300. In normal use, the buckle is engaged with the bayonet 340, thereby ensuring that the pipeline clamp 500 is always located at the position of the connector 110, and the nursing staff does not need to look for the pipeline clamp 500 at other positions during operation;
[0058] like Figure 1 and Figure 6 As shown, in the connected state, the size of the opening 510 of the pipeline clamp 500 does not match the size of the left end of the connector 110 , and the pipeline clamp 500 cannot be separated from the connector 110 , thereby being able to assist in positioning the sleeve 300 .
[0059] like Figure 6 As shown, the height of the pipeline clamp 500 is higher than the height of the left end of the sleeve 300, and the width of the front and rear ends of the pipeline clamp 500 is smaller than the width of the sleeve 300. Through this size difference, the nursing staff can easily and quickly separate the pipeline clamp 500 and the sleeve 300.
[0060] Embodiment 2:
[0061] Different from the first embodiment, the positioning portion includes a first positioning groove 321 and a second positioning groove 322 axially arranged on the slide rod 320 to provide two different locking states.
[0062] Specifically, Figure 7 As shown, in addition to the first positioning groove 321 , the sliding rod 320 is further provided with a second positioning groove 322 . The second positioning groove 322 is located at the left end of the first positioning groove 321 , and the limiting protrusion 330 is located at the left side of the second positioning groove 322 .
[0063] It can be understood that, in normal use, the locking member 400 is rotated, and the engaging portion 410 of the locking member 400 cooperates with the first positioning groove 321. At this time, the cross section of the sleeve 300 is Figure 5 In the state, the first elastic arm 311 and the second elastic arm 312 lock the plug and the second conduit 200;
[0064] When the drainage bag needs to be replaced, the sleeve 300 is moved on the second catheter 200 away from the plug, and the locking piece 400 is moved to the second positioning groove 322. After rotation, the clamping portion 410 of the locking piece 400 cooperates with the second positioning groove 322. At this time, due to the different positions of the contact protrusion 420, the angle between the first elastic arm 311 and the second elastic arm 312 is smaller, so the second catheter 200 can be closed to replace the medical clamping scissors.
[0065] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
