Description

Technical Field

[0001] The invention relates to the technical field of medical drainage tube fixation, in particular to a drainage tube fixing device for hepatobiliary pancreatic spleen surgical drainage. Background Art

[0002] After hepatobiliary, pancreatic and splenic surgery, drainage tubes are usually used to effectively remove body fluids, blood or other secretions and prevent infection and other complications. The main function of the drainage tube is to safely guide these body fluids to the outside of the body to ensure wound cleanliness and promote healing. The drainage tube retaining device plays a vital role. It ensures that the drainage tube can be stably fixed in the patient's body to avoid displacement, falling off or twisting, thereby ensuring an effective drainage process and maintaining the safety of the patient.

[0003] At present, the widely used hepatobiliary pancreatic spleen surgical drainage tube retention device in clinical practice includes a Velcro dressing attached to the skin surface and a cable tie for fastening the position of the drainage tube.

DETAILED DESCRIPTION

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0044] Example 1

[0045] Reference Figure 1-2 , which is the first embodiment of the present invention, and provides a drainage tube holding device for hepatobiliary pancreatic spleen surgical drainage, which includes a holding unit 1, including two sets of lifting caps 11, a first clamping tube 12 arranged at the bottom of the lifting cap 11, a second clamping tube 13 arranged at one side of the first clamping tube 12, and a holding member 14 arranged inside the first clamping tube 12 and the second clamping tube 13;

[0046] The rotating unit 2 includes a connecting plate 21 slidably connected to the inner sides of the first clamping cylinder 12 and the second clamping cylinder 13, a plurality of mounting seats 22 arranged on one side of the connecting plate 21, an adhesive surface 23 arranged at the bottom of the mounting seat 22, and a cable tie 24 arranged on the inner side of the mounting seat 22;

[0047] The Velcro 3 includes an annular fleece surface 31 arranged on its end surface.

[0048] It should be noted that the Velcro 3 is a prior art, and a group of annular velvet surfaces 31 are fixedly bonded on its surface; the annular velvet surfaces 31 can limit the movement of the rotating unit 2. The holding unit 1 is fixedly set at the center of the Velcro 3 by bonding, and a circular groove of a certain diameter is left inside it to facilitate the fixing of the drainage tube. The inner wall of the holding unit 1 limits the movement trajectory of the rotating unit 2 by sliding and clamping.

[0049] Preferably, the holding unit 1 has a first clamping tube 12 and a second clamping tube 13 that can be hinged on both sides to hold the drainage tube. A lifting cap 11 is provided at the ends of the first clamping tube 12 and the second clamping tube 13, and a holding member 14 is slidably provided inside the first clamping tube 12 and the second clamping tube 13. The holding member 14 can be retracted inward by lifting the lifting cap 11 upward, thereby clamping the drainage tube inside.

[0050] Preferably, the rotating unit 2 rotates with the holding unit 1 as the center. The rotating unit 1 is composed of a connecting plate 21, a mounting seat 22 fixedly arranged on one side of the connecting plate 21, an adhesive surface 23 fixedly arranged at the bottom of the mounting seat 22, and a cable tie 24 sleeved on the inner side of the mounting seat 22. One end of the connecting plate 21 is slidably clamped on the inner wall of the first clamping tube 12 and the second clamping tube 13, so that it can rotate with the holding unit 1 as the center.

[0051] When in use, the opening on one side of the Velcro 3 is clamped on the drainage tube and applied to the patient's skin. Then, the fingers are buckled to the two sides of the two sets of lifting caps 11, so that the retaining parts 14 automatically shrink inward and clamp the drainage tube, which can be stably fixed in the patient's body to avoid displacement, falling off or twisting. The upwardly buckled lifting cap 11 will also release the fixation of the connecting plate 21, allowing it to rotate, and then the direction of the connecting plate 21 can be adjusted. In this process, the retaining part 14 will clamp the drainage tube, and adjust the position of the connecting plate 21; prevent the drainage tube from twisting after changing its direction, and then cause the patient's wound and the drainage tube healing area to be involved. After the position of the connecting plate 21 is adjusted, the drainage tube is tightened with a cable tie 24, and then the sticky surface 23 at the bottom of the mounting seat 22 is attached to the annular rough surface 31 to complete the fixing effect.

[0052] In summary, the device realizes flexible adjustment of the position of the drainage tube by improving the settings of the Velcro 3, the holding unit 2 and the rotating unit 1, while reducing the pressure and traction on the wound area. The holding member 14 can change the path of the drainage tube without increasing the patient's pain. In addition, the design of the first clamping tube 12 and the second clamping tube 13 can stably fix the drainage tube and avoid unnecessary movement, thereby reducing stimulation to the patient. And the hinged opening and closing of the first clamping tube 12 and the second clamping tube 13 do not need to be inserted from the root of the drainage tube, which effectively avoids the inconvenience and potential risks caused by the line drawing. It not only simplifies the operating process, but also improves the nursing efficiency, ensuring that the drainage process is smoother and safer.

[0053] Example 2

[0054] Reference Figure 3 to Figure 7 , which is the second embodiment of the present invention, and is different from the first embodiment in that: the lifting cap 11 includes a buckle brim 111, a clamping plate 112 protruding from the bottom of the buckle brim 111, and a downward pressing tooth ring 113 protruding from one side of the buckle brim 111;

[0055] The first clamping cylinder 12 and the second clamping cylinder 13 have the same structure and are hinged together via a hinge shaft 15 on one side of both.

[0056] It should be noted that if Figure 3 As shown, the lifting cap 11 is composed of a buckle brim 111, a clamping plate 112 protruding from the bottom of the buckle brim 111, and a downward pressing tooth ring 113 protruding from the outside of the clamping plate 112. The buckle brim 111 has a large diameter, which is convenient for medical staff to clamp and use. The clamping plate 112 is clamped by the retaining member 14 on the end surfaces of the first clamping cylinder 12 and the second clamping cylinder 13.

[0057] Preferably, the first clamping tube 12 and the second clamping tube 13 have the same structure and are both disc-shaped, and one side of both sides is provided with a hinge shaft 15, and they are hinged together through the hinge shaft 15; so that they can realize a certain angle of rotation and opening and closing movement with the hinge shaft 15, which is convenient for clamping the drainage tube, avoiding the use of inserting the drainage tube from the head of the drainage tube, and reducing the pulling of the drainage tube. The other side of the first clamping tube 12 and the second clamping tube 13 is also provided with a buckle, so that the two sides can be buckled together.

[0058] Furthermore, the first clamping cylinder 12 includes an upper disk surface 121 disposed at the bottom of the clamping disk 112 , a clamping plate 122 disposed outside the upper disk surface 121 , an annular cylinder 123 disposed at the bottom of the upper disk surface 121 , and a base 124 disposed at the bottom of the annular cylinder 123 .

[0059] Furthermore, the connecting plate 21 includes a straight plate 211 slidably disposed at the end of the base 124 , and an arc plate 212 disposed at the end of the straight plate 211 ;

[0060] The arc plate 212 includes an upper tooth surface 2121 disposed at an end thereof;

[0061] The upper tooth surface 2121 is engaged with the lower pressure tooth ring 113 .

[0062] Further, the avoidance opening 125 between the clamping plate 122 and the base 124, and the arc-shaped path 126 between the clamping plates 122;

[0063] The straight plate 211 is limited in the avoidance opening 125 , and the arc plate 212 is limited in the arc path 126 .

[0064] It should be noted that if Figure 4 As shown, the first clamping cylinder 12 is composed of an upper disk surface 121 at the end, a clamping plate 122 extending downward from the upper disk surface 121, an annular cylinder 123 at the bottom of the upper disk surface 121, and a base 124 at the bottom of the annular cylinder 123. The upper disk surface 121 is arranged at the bottom of the clamping disk 112, and the clamping plate 122 is an integral structure with the upper disk surface 121. The clamping plate 122 is composed of two groups of arc plates with different diameters at the bottom of the upper disk surface 121, and an arc path 126 is provided in the middle of the two groups of arc plates. The arc path 126 is extended upward from the connecting plate 21 to cooperate with the downward pressing gear ring 113.

[0065] Better, such as Figure 4As shown, the connecting plate 21 is composed of a straight plate 211 extending outward, and an arc plate 212 clamped on one side of the straight plate 211. The side of the straight plate 211 extending outward is fixedly clamped on one side of the mounting seat 22. The arc plate 212 is limited in the arc path 126 so that it can slide in the arc path 126. The first clamping cylinder 12 and the second clamping cylinder 13 have the same structure, so that after the first clamping cylinder 12 and the second clamping cylinder 13 are clamped into a circle, the arc plate 212 can slide in the arc path 126 on the end surfaces on both sides thereof to maximize the rotation angle.

[0066] Preferably, an upper tooth surface 2121 with multiple groups of teeth in a circumferential array is fixed on the end surface of the arc plate 212, and a group of downward pressure tooth rings 113 are protruded outwardly on one side of the lifting cap 11 to be relatively engaged with the upper tooth surface 2121. The upper circumferential array of the downward pressure tooth ring 113 has teeth. When the clamping plate 112 is attached to the end surface of the upper plate surface 121, the downward pressure tooth ring 113 and the upper tooth surface 2121 are relatively engaged, so that the downward pressure tooth ring 113 limits the upper tooth surface 2121, thereby limiting the connection plate 21.

[0067] Furthermore, the clamping plate 112 includes a clamping groove 1121 extending through the end portion;

[0068] The retaining member 14 includes a limiting rod 141 slidably disposed inside the engaging groove 1121 , a sliding block 142 disposed at the bottom of the limiting rod 141 , a spring 143 sleeved on the outside of the limiting rod 141 , and an elastic rope 144 disposed inside the sliding block 142 .

[0069] Furthermore, the limiting rod 141 includes a clamping block 1411 disposed at an end thereof;

[0070] The upper plate surface 121 includes a limiting groove 1211 penetratingly arranged on its end surface;

[0071] The limiting rod 141 is in the limiting groove 1211 , and the clamping block 1411 is clamped at the end of the clamping groove 1121 .

[0072] It should be noted that if Figure 5 As shown, a clamping groove 1121 is provided on the end surface of the clamping disk 112, and a limiting groove 1211 is also provided on the end surface of the upper disk surface 121. The notch shapes of the clamping groove 1121 and the limiting groove 1211 are consistent, and both face the center of the circle of the first clamping cylinder 12. A set of limiting rods 141 are slidably connected in the notches of the clamping groove 1121 and the limiting groove 1211, and a clamping block 1411 is fixedly clamped at the end of the limiting rod 141, and the diameter of the clamping block 1411 is larger than the notch size of the clamping groove 1121, so that the clamping disk 112 will be restricted by the clamping block 1411. When the limiting rod 141 is pushed from the outside to the inside, the limiting rod 141 will move toward the center of the circle under the restriction of the limiting groove 1211.

[0073] Preferably, a group of springs 143 are sleeved on the outer side of the limiting rod 141, one end of the spring 143 abuts against the upper end surface of the sliding block 142, and the other side of the spring 143 abuts against the lower end surface of the limiting groove 1211. The spring 143 is always compressed, thereby pressing the sliding block 142 downward, and then the clamping block 1411 always presses down the positioning plate 112, so that the downward pressing tooth ring 113 on one side of the positioning plate 112 is always clamped in the upper tooth surface 2121, thereby fixing the connecting plate 21.

[0074] Furthermore, the sliding block 142 includes an arc-shaped hole 1421 penetrating the inner side thereof, and a contact surface 1422 protruding from one side thereof;

[0075] The ring tube 123 includes a plurality of groups of travel windows 1231 penetratingly arranged on its wall surface;

[0076] The elastic rope 144 is inserted into the arc hole 1421 , and the abutting surface 1422 is slidably located in the traveling window 1231 .

[0077] Further, the arc-shaped channel 126 includes an opening 1261 disposed on one side thereof;

[0078] The opening 1261 is disposed on one side of the hinge shaft 15;

[0079] The arc plate 212 can enter the other side arc plate 212 through the opening 1261 .

[0080] It should be noted that if Figure 6 As shown, the inner side of the sliding block 142 is penetrated with an arc hole 1421, and a group of elastic ropes 144 are slidably connected in the arc hole 1421. The retaining member 14 in this embodiment is symmetrically arranged with 3 on the left and 3 on the right, and there are two groups of elastic ropes 144, one group of which penetrates and connects three groups of arc holes 1421 on the same side at the same time, so that when the elastic rope 144 contracts, it will drive the three groups of sliding blocks 142 to contract inward at the same time. The end face of the sliding block 142 is clamped with a butt surface 1422, which is made of a flexible arc surface material to reduce the extrusion deformation when the drainage tube is held.

[0081] Preferably, the openings of the arc-shaped paths 126 on the first clamping tube 12 and the second clamping tube 13 are both arranged at the hinge shaft 15, so that the arc plate 212 in the arc-shaped paths 126 can slide without being pressed by the downward pressure gear ring 113, thereby avoiding sliding out at the opening and closing position. When the hinge shaft 15 closes the first clamping tube 12 and the second clamping tube 13, the arc plate 212 can slide into the arc-shaped paths 126 at another position, and vice versa when the first clamping tube 12 and the second clamping tube 13 are opened, the arc plate 212 cannot slide out of the arc-shaped paths 126, so that it slides relatively in the two sets of arc-shaped paths 126 and cannot be separated.

[0082] Furthermore, the sliding block 142 further includes a retaining tooth 1423 protruding from the bottom thereof;

[0083] The base 124 includes a plurality of baffles 1241 disposed at the bottom thereof;

[0084] The baffle 1241 limits the movement of the baffle teeth 1423 .

[0085] It should be noted that if Figure 7 As shown, a group of retaining teeth 1423 are fixedly connected at the bottom of each group of sliding blocks 142, and a group of baffles 1241 are fixedly connected on the base 124. The tooth roots of the plate teeth on the baffle 1241 and the tooth tips of the retaining teeth 1423 are both facing away from the center of the circle. During the movement of the sliding block 142 toward the center of the circle, the cooperation of the baffle 1241 and the retaining teeth 1423 can prevent it from retreating, but does not restrict its advancement to a certain extent. Ensure that it can be stably fixed in the patient's body in the event of accidental touch to avoid displacement, falling off or twisting. The baffle 1241 and the retaining teeth 1423 are made of rubber material and are elastic. The elasticity of the tips of the two is poor. When under the pressure of the spring 143, the baffle 1241 will be pressed down in the tooth gap of the retaining teeth 1423, and the baffle 1241 cannot move the retaining teeth 1423 toward the center of the circle, preventing the elastic rope 144 from pulling the sliding block 142 to continue to move forward. When the sliding block 142 is lifted upward, the baffle 1241 contacts the tooth tip of the baffle tooth 1423 or is out of engagement, causing the elastic rope 144 to pull the sliding block 142 to continue moving forward.

[0086] When in use, the buckle rim 111 is lifted upward by the fingers, and the clamping block 1411 overlaps the end of the clamping groove 1121 to lift the bottom sliding block 142; after the sliding block 142 is lifted, the baffle 1241 contacts the tooth tip of the retaining tooth 1423 or is out of meshing state, causing the elastic rope 144 to contract and then pull the sliding block 142 forward. The abutting surface 1422 is pushed out from the advancing window 1231 and finally abuts against the body of the drainage tube to hold and clamp it. At the same time, the buckled buckle rim 111 will also separate the pressing tooth ring 113 from the upper tooth surface 2121. At this time, the pressing tooth ring 113 cannot continue to limit the upper tooth surface 2121, so that it can rotate, thereby realizing the adjustment of the mounting seat 22 on the other side of the connecting plate 21 to meet the direction requirements of the drainage tube. When the direction of the drainage tube needs to be adjusted, the elastic rope 144 will always be clamped at the point where the drainage tube is in contact with the skin wound, preventing this section of the drainage tube from twisting with the whole tube and affecting the wound cracking, significantly reducing the pressure and traction on the wound area, helping to create a more stable healing environment and promoting faster wound recovery.

[0087] After adjusting the position of the drainage tube, the buckle 111 is loosened, and the sliding block 142 at the bottom thereof is pressed back under the action of the spring 143, so that the baffle 1241 is pressed down in the tooth gap of the baffle teeth 1423, and the elastic rope 144 presses the abutting surface 1422 against the body of the drainage tube.

[0088] In summary, the device realizes flexible adjustment of the position of the drainage tube by improving the settings of the Velcro 3, the holding unit 2 and the rotating unit 1, while reducing the pressure and traction on the wound area. The holding member 14 can change the path of the drainage tube without increasing the patient's pain. In addition, the design of the first clamping tube 12 and the second clamping tube 13 can stably fix the drainage tube and avoid unnecessary movement, thereby reducing stimulation to the patient. And the hinged opening and closing of the first clamping tube 12 and the second clamping tube 13 do not need to be inserted from the root of the drainage tube, which effectively avoids the inconvenience and potential risks caused by the line drawing. It not only simplifies the operating process, but also improves the nursing efficiency, ensuring that the drainage process is smoother and safer.

[0089] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
