Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a abdominal drainage tube with scales. Background Art

[0002] Drainage tubes are used for clinical surgical drainage. They are a kind of medical device that guides pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. Common ones include abdominal drainage tubes, chest drainage tubes, and biliary drainage tubes. They are generally made of materials such as silicone rubber or polyurethane. When in use, one end of the catheter is inserted into the drainage site in the body or on the wound surface, and the other end can be connected to other external devices such as drainage tubes outside the body to drain to the outside of the body through the action of pressure such as body pressure, gravity, or negative pressure suction; it is provided sterile and for single use.

[0003] The graduated abdominal drainage tube is designed to help medical staff quickly know the depth of the drainage tube.

[0004] However, existing abdominal drainage tubes are often bent and deformed due to changes in the patient's body position, such as turning over, which in turn affects the normal operation of the drainage tube, making it impossible to drain the abdominal effusion smoothly and easily causing blockage, which increases the workload of medical staff.

[0005] Therefore, it is necessary to provide a graduated abdominal drainage tube to solve the above problems. Utility Model Content

[0006] In view of the above problems, the purpose of the utility model is to provide a peritoneal drainage tube with a scale, which solves the problem that the existing peritoneal drainage tube bends and deforms due to changes in the patient's body position, such as turning over, thereby affecting the normal work of the drainage tube, making it impossible to drain the abdominal effusion smoothly, and easily causing blockage, thereby increasing the workload of medical staff.

[0007] The technical solution adopted by the utility model is as follows: a graduated abdominal drainage tube comprises a tube body, on which a movable anti-extrusion component is provided; the anti-extrusion component comprises a lower shell body and an upper shell body arranged relatively to each other, rollers are installed in the lower shell body and the upper shell body, the annular grooves on the outer walls of the rollers cooperate with the outer walls of the tube body, fixing parts are provided inside the lower shell body and the upper shell body, first compression springs are installed between the fixing parts and the corresponding lower shell body, and between the fixing parts and the corresponding upper shell body, and bolts for pushing the fixing parts are installed on the lower shell body and the upper shell body.

[0008] Furthermore, a rubber pad is installed on one side of the fixing member close to the tube body.

[0009] Furthermore, a limit rod is installed on the fixing member, and the limit rod passes through the corresponding lower shell and upper shell and then extends outward.

[0010] Furthermore, a quick-release assembly is provided between the lower shell and the upper shell; the quick-release assembly includes a vertical rod installed on the lower shell, the upper shell is sleeved on the suspended end of the vertical rod, a cavity is opened on the upper shell, a second compression spring is provided inside the cavity, a pull rod is installed at the extended end of the second compression spring, the pull rod is slidably connected to the cavity, and the pull rod is plugged into the vertical rod.

[0011] Furthermore, a support seat is provided on the vertical rod.

[0012] Furthermore, the lower surface of the pull rod plug-in end is wedge-shaped, and the vertical rod is provided with a groove for the pull rod plug-in end to be plugged in.

[0013] Furthermore, a plurality of drainage holes are provided at the front end of the tube body.

[0014] Furthermore, a hard tube is installed at one end of the tube body away from the drainage hole, and a one-way valve is installed inside the hard tube.

[0015] Furthermore, the tube body is provided with scale lines.

[0016] Furthermore, a developing line is provided on the tube body.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] 1. The graduated abdominal drainage tube ensures the normal operation of the drainage tube by arranging a movable anti-extrusion component on the tube body, drains the accumulated fluid in the abdominal cavity smoothly, and avoids the drainage tube being squeezed due to changes in the patient's position, such as turning over, resulting in bending and deformation to block the channel, causing the drainage tube to fail to work normally, thereby reducing the workload of medical staff and improving work efficiency. At the same time, since the anti-extrusion component is movable, the medical staff can move and adjust the anti-extrusion component along the tube body of the drainage tube according to actual usage. The structural design is simple and convenient for medical staff to operate.

[0019] 2. By installing a rubber pad on the fixing, the friction between the fixing and the body of the drainage tube is increased, thereby improving the stability of the anti-extrusion component and preventing medical staff from excessively turning the bolts, causing excessive movement of the fixing and squeezing the body of the drainage tube.

[0020] 3. By installing a limit rod on the fixing part, it is ensured that the fixing part can move vertically under the action of the bolt without deviation.

[0021] 4. By installing quick-release components on the lower shell and the upper shell, the lower shell and the upper shell can be quickly disassembled and installed, which is convenient for medical staff to maintain them. The structural design is simple and easy for medical staff to operate, which greatly reduces the workload of medical staff and improves work efficiency.

[0022] 5. By arranging a support seat on the vertical rod, after the upper shell and the lower shell are assembled, the support seat plays a role of stabilizing the upper shell.

[0023] 6. By setting the lower surface of the pull rod plug-in end to a wedge shape, when the upper shell is sleeved on the vertical rod of the lower shell, the downward force generates a lateral movement component under the action of the wedge-shaped lower surface of the pull rod plug-in end, causing the pull rod to slide along the cavity of the upper shell. At this time, the second compression spring is compressed. When it moves to the groove position on the vertical rod, the vertical rod no longer generates thrust on the pull rod, causing the second compression spring to lose external force support and return to its original state, thereby driving the pull rod to be plugged into the groove of the vertical rod, making it convenient for medical staff to quickly assemble the upper shell and the lower shell together. The structural design is simple, which is convenient for staff to operate, and further reduces the workload of medical staff.

[0024] 7. By opening a drainage hole on the tube body, the accumulated fluid in the patient's abdominal cavity can enter the tube body through the drainage hole and finally be discharged from the body. At the same time, by setting scale lines on the tube body, it is convenient for medical staff to quickly know the depth of the tube body. The purpose of setting the development line on the tube body is to help medical staff determine the exact position of the tube body in the patient's body.

[0025] 8. By installing a hard tube on the tube body and installing a one-way valve inside the hard tube, when the tube body is connected to the external negative pressure equipment through the hard tube, under normal working conditions, the accumulated fluid flows into the external negative pressure equipment through the one-way valve under the action of the external negative pressure equipment. When the external negative pressure equipment is full of accumulated fluid and needs to be replaced, the hard tube is separated from the external negative pressure equipment. At this time, under the action of the one-way valve, the residual accumulated fluid in the tube body will not flow out, thereby not causing occupational exposure, thereby ensuring the life safety of medical staff.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] Combine the following Figure 1-Figure 3 The utility model is described in detail.

[0035] Example

[0036] Depend on Figure 1-3It can be seen that a graduated abdominal drainage tube includes a tube body 1. The material of the tube body 1 can be made of medical silicone rubber. The specific model is not specifically limited here, and it can meet the actual use requirements. A movable anti-extrusion component is provided on the tube body 1; the anti-extrusion component includes a lower shell 5 and an upper shell 6 that are relatively arranged, and rollers 7 are installed in the lower shell 5 and the upper shell 6. The annular groove on the outer wall of the roller 7 cooperates with the outer wall of the tube body 1. The lower shell 5 and the upper shell 6 play a protective role to prevent the external environment from causing extrusion and deformation of the tube body 1. The transparent shell made of polycarbonate is not only convenient for medical staff to observe the movement of the fixing part 8 to avoid excessive movement and causing extrusion and deformation of the tube body 1; it also ensures that medical staff can observe the normal flow of the effusion in the tube body 1.

[0037] At the same time, the interior of the lower shell 5 and the upper shell 6 are both provided with fixing parts 8, and the first compression springs 9 are both installed between the fixing parts 8 and the corresponding lower shell 5, and between the fixing parts 8 and the corresponding upper shell 6, and the bolts 11 for pushing the fixing parts 8 are both installed on the lower shell 5 and the upper shell 6. Due to the setting of the roller 7, the anti-extrusion component can be moved along the tube body 1, so that the medical staff can move the anti-extrusion component to the corresponding position according to the actual use situation. For example, when the patient's body position changes and turns over, the tube body 1 is squeezed and bent. The medical staff can move the anti-extrusion component to this place through the roller 7, and turn the bolt 11, so that the fixing part 8 moves vertically under the action of the bolt 11 and presses against the outer wall of the tube body 1. At this time, the first compression spring 9 produces elastic deformation under the action of external force, so that the lower shell 5 and the upper shell 6 are fixed here to avoid bending here and affecting the normal drainage work of the tube body 1.

[0038] In addition, a rubber pad 12 is installed on the side of the fixing part 8 close to the tube body 1. The rubber pad 12 serves to increase friction, so that medical staff can turn the bolt 11 to push the fixing part 8 to move and contact the outer wall of the tube body 1, thereby fixing the lower shell 5 and the upper shell 6 in corresponding positions, preventing the medical staff from turning the bolt 11 excessively, causing the fixing part 8 to move too much and squeeze the tube body 1.

[0039] In addition, a limit rod 10 is installed on the fixing member 8. The limit rod 10 passes through the corresponding lower shell 5 and upper shell 6 and then extends outward. The limit rod 10 plays a limiting role to ensure that the fixing member 8 can move vertically under the action of the bolt 11 without deviation.

[0040] It is worth pointing out that the anti-extrusion component itself is very small. Although during use, its protruding parts, namely the limit rod 10 and the bolt 11 exposed outside the lower shell 5 and the upper shell 6, may cause slight discomfort to the patient, for example, when the patient turns over, the patient's body may be hit. At this time, the medical staff can install a sponge cover on the anti-extrusion component to alleviate the discomfort. The sponge cover can be wrapped around the anti-extrusion component with Velcro to ensure the normal operation of the anti-extrusion component and alleviate the patient's slight discomfort. In addition, Figure 1 The position of the anti-extrusion component on the tube body 1 is only a schematic diagram and does not represent the location of the anti-extrusion component. Figure 1 The position of the middle tube body 1.

[0041] In addition, a quick release assembly is provided between the lower shell 5 and the upper shell 6; the quick release assembly includes a vertical rod 13 installed on the lower shell 5, the upper shell 6 is sleeved on the suspended end of the vertical rod 13, a cavity is provided on the upper shell 6, a second compression spring 16 is provided inside the cavity, a pull rod 15 is installed at the extended end of the second compression spring 16, the pull rod 15 is slidably connected with the cavity, and the pull rod 15 is plugged and matched with the vertical rod 13. The cavity on the upper shell 6 limits the pull rod 15, so that the pull rod 15 can only slide along the inside of the cavity.

[0042] Furthermore, a support seat 14 is provided on the vertical rod 13 , so that after the upper shell 6 and the lower shell 5 are assembled, the support seat 14 plays a role of stabilizing and supporting the upper shell 6 .

[0043] It is worth noting that since the lower surface of the plug-in end of the pull rod 15 is wedge-shaped and a groove is provided on the vertical rod 13 for the plug-in end of the pull rod 15 to be plugged in, when the upper shell 6 is sleeved on the vertical rod 13 of the lower shell 5, the downward force generates a lateral movement component under the action of the wedge-shaped lower surface of the plug-in end of the pull rod 15, causing the pull rod 15 to slide along the cavity of the upper shell 6. At this time, the second compression spring 16 is compressed. When it moves to the groove position on the vertical rod 13, the vertical rod 13 no longer generates a thrust on the pull rod 15, causing the second compression spring 16 to lose external force support and return to its original state, thereby driving the pull rod 15 to be plugged into the groove of the vertical rod 13, which is convenient for medical staff to quickly operate to assemble the upper shell 6 and the lower shell 5 together. Its structural design is simple, which is easy for staff to operate, and further reduces the workload of medical staff.

[0044] Furthermore, the front end of the tube body 1 is provided with a plurality of drainage holes 2. The accumulated fluid in the patient's body enters the tube body 1 through the drainage holes 2, and finally flows into the external negative pressure device through the one-way valve in the hard tube 17.

[0045] In addition, a hard tube 17 is installed at one end of the tube body 1 away from the drainage hole 2. The specific installation method is not limited, and it can be a plug-in or threaded connection. A one-way valve is installed inside the hard tube 17. The model of the one-way valve is not specifically limited here, and it can meet the actual use requirements.

[0046] Under the negative pressure of the external negative pressure device, the one-way valve in the hard tube 17 opens, and the accumulated fluid in the patient's body enters the tube body 1 through the drainage hole 2, and flows into the external negative pressure device through the one-way valve in the hard tube 17. When the accumulated fluid in the external negative pressure device connected to the hard tube 17 is full, it needs to be replaced. At this time, the hard tube 17 is separated from the external negative pressure device, and the accumulated fluid in the tube body 1 will not flow out under the action of the one-way valve, thereby not causing occupational exposure, thereby ensuring the life safety of medical staff.

[0047] Furthermore, the tube body 1 is provided with scale lines 3, which facilitates medical staff to quickly know the penetration length of the tube body 1. The tube body 1 is provided with a developing line 4, which helps medical staff to determine the exact position of the tube body 1 in the patient's body.

[0048] Specifically, when using the graduated abdominal drainage tube, first connect the tube body 1 to the external negative pressure equipment through the hard tube 17; then insert one end of the tube body 1 with the drainage hole 2 into the drainage site in the patient's body to drain the abdominal fluid, and the depth is known by observing the scale line 3 on the tube body 1; then assemble the lower shell 5 and the upper shell 6 to the tube body 1, and after the annular groove on the outer wall of the roller 7 on the lower shell 5 is matched with the outer wall of the tube body 1, the upper shell 6 is sleeved on the vertical rod 13 of the lower shell 5. At this time, the wedge-shaped lower surface of the plug-in end of the pull rod 15 generates a component force, so that the pull rod 15 slides along the cavity of the upper shell 6. At this time, the second compression spring 16 produces elastic deformation, but when it moves to the groove on the vertical rod 13, the second compression spring 16 loses external force support and returns to its original state, and drives the pull rod 15 to be plugged into the groove of the vertical rod 13, thus completing the assembly of the lower shell 5 and the upper shell 6.

[0049] After the lower shell 5 and the upper shell 6 are assembled, the medical staff can move them to the desired position. For example, when the patient's body position changes and turns over, causing the tube body 1 to be squeezed and bent, the medical staff can move the anti-extrusion component to this place through the roller 7 and rotate the bolt 11, so that the fixing part 8 moves vertically under the action of the bolt 11 and presses against the outer wall of the tube body 1. At this time, the first compression spring 9 produces elastic deformation under the action of external force, so that the lower shell 5 and the upper shell 6 are fixed here to avoid bending here and affecting the normal drainage work of the tube body 1.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
