One end of the drainage tube is inserted into the drainage site of the human body, and the other end of the drainage tube is connected to the drainage bag. The drainage bag is fixed to a medical bed by the paperclip.

[0004] However, in some situations, the drainage tube may be stretched, which can easily lead to it coming out. Utility Model Content

[0005] This application provides a fixing device for the drainage tube and the drainage tube itself, so as to achieve the effect that the drainage tube is not easily dislodged when it is pulled by force.

[0006] In a first aspect, embodiments of this application provide a device for fixing a drainage device, comprising:

[0007] device body;

[0008] The positioning element is set on the device body and has a positioning hole for the drainage tube of the drainage device to pass through.

[0009] The blocking component is installed on the device body and is used to support the drainage tube so that the drainage tube is bent.

[0010] In one possible implementation, the fixation device for the drainage device further includes:

[0011] The fastener is used to be sleeved on the drainage tube and inserted into the positioning hole.

[0012] In one possible implementation, at least two blocking elements are provided, with each blocking element spaced apart and located on the same circumference.

[0013] In one possible implementation, the fastener is interference-fitted with the positioning hole.

[0014] In one possible implementation, there are two blocking elements, which are respectively disposed on both sides of the positioning element.

[0015] In one possible implementation, the fastener is an elastic member, and the fastener has:

[0016] A perforation is used for the passage of a drainage tube;

[0017] A plug hole is formed by passing through the side wall of the fastener and connecting the pipe hole to the outside of the fastener.

[0018] In one possible implementation, there are two blocking elements, which are respectively disposed on both sides of the positioning element.

[0019] In one possible implementation, the radial width of the fastener gradually decreases along the insertion direction of the fastener.

[0020] In one possible implementation, the positioning element also has a through hole that penetrates the side wall of the positioning element, connects the positioning hole to the outside of the positioning element, and allows a drainage tube to pass through.

[0021] In one possible implementation, the blocking element is a baffle protruding from the device body, the baffle being curved and used to support the drainage tube.

[0022] Alternatively, the blocking element is a groove provided on the device body, with the groove wall being curved, and the groove is used to support the drainage tube in contact.

[0023] In one possible implementation, the fixation device for the drainage device further includes:

[0024] The first hook and the second hook are both set on the device body. The first hook and the second hook are respectively set on both sides of the positioning component. The first hook is used to support the device body and the second hook is used to support the drainage bag of the drainage device.

[0025] At least one mounting element is provided for mounting an identification element of the drainage device, the identification element being used to identify drainage tube information, the drainage tube information including at least one of drainage tube type and drainage tube expiration date.

[0026] Secondly, embodiments of this application provide a drainage device, comprising:

[0027] Any of the fixing devices provided in the first aspect;

[0028] The drainage tube is inserted into the positioning hole of the fixing device.

[0029] In one possible implementation, the number of fixing devices is two or more;

[0030] The device body of the fixing device has a plug-in part and a plug-in interface, and the plug-in part of one of two adjacent device bodies is inserted into the plug-in interface of the other of the two adjacent device bodies.

[0031] The present application provides a fixing device and a drainage device for a drainage tube. The fixing device has a positioning member with a positioning hole on its main body. When the drainage tube is inserted into the positioning hole, it is fixed to the main body, preventing displacement. A blocking member is also provided on the main body. When the drainage tube is fixed to the main body, it abuts against the blocking member, providing support and guiding it to a curved shape. This curved shape provides a buffering effect. When the drainage tube is pulled by an external force, the force is first applied to the curved portion, changing the direction of the force. The direct tension is converted into a force that straightens the curved portion, rather than acting directly on the insertion site, reducing the risk of dislodgement. Furthermore, the curved portion of the drainage tube is contained within the blocking member, minimizing the length of the tube exposed outside the fixing device, which facilitates installation and management.

[0052] This application provides a drainage device. Figure 1 This is a schematic diagram of the structure of a drainage device with multiple fixing devices 10 provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a drainage device with a fixing device 10 provided in an embodiment of this application. Figure 3 for Figure 2 A schematic diagram of the drainage device from another perspective.

[0053] Specifically, please refer to Figures 1 to 3 The drainage device includes a fixing device 10 and a drainage tube 20 disposed on the fixing device 10. The drainage tube 20 is used to guide body fluids from the human body to the outside of the human body.

[0054] In this embodiment, the drainage tube 20 is used to guide bodily fluids from inside the body to outside the body, which can prevent postoperative infection and promote wound healing. The fixation device 10 provides a supporting base for the drainage tube 20, facilitating its management.

[0055] It should be noted that this embodiment does not limit the location of the fixing device 10, and it can be adjusted according to specific needs. For example, the fixing device 10 can be installed on the bed frame, bed board, or railing of the medical bed.

[0056] It should also be noted that this embodiment does not limit the specific application scenarios of the drainage device, and can be adjusted according to specific needs. For example, the drainage device can be used to guide human blood, urine, or gastric contents.

[0057] In some embodiments, please continue reading Figures 1 to 3 The drainage device also includes a drainage bag 30, which is mounted on the fixing device 10; one end of the drainage tube 20 is used to insert into the drainage site of the human body, and the other end of the drainage tube 20 is connected to the drainage bag 30.

[0058] In this embodiment, the drainage bag 30 is used to receive bodily fluids guided by the drainage tube 20. The fixing device 10 provides a supporting base for the drainage bag 30, facilitating its management.

[0059] It should be noted that the drainage bag 30 and drainage tube 20 provided in this embodiment can be set as a whole, and the integrated drainage bag 30 and drainage tube 20 can be set on the fixing device 10 at one time.

[0060] In other embodiments, please refer to Figure 1 and Figure 2 The fixing device 10 includes a device body 100, and the number of fixing devices 10 is two or more, and the number of drainage tubes 20 is two or more, with the drainage tubes 20 correspondingly arranged on the device body 100.

[0061] The device body 100 has a plug-in part and a plug-in interface, and the plug-in part of one of two adjacent device bodies 100 is inserted into the plug-in interface of the other of the two adjacent device bodies 100.

[0062] In this embodiment, multiple fixation devices 10 can simultaneously guide various bodily fluids. In complex medical situations, patients may need to drain multiple bodily fluids simultaneously, such as postoperative drainage of blood and exudate. By using multiple fixation devices 10, the operator can set up independent drainage areas for each bodily fluid, avoiding mixing of different fluids and facilitating separate collection and observation.

[0063] The plug-in connection method allows multiple fixing devices 10 to be quickly combined or disassembled, thereby improving the efficiency of fixing device 10 assembly, disassembly and adjustment.

[0064] For some specific implementation methods, please refer to Figure 2The connector includes a first connector 110, which is disposed on the top of the device body 100 and protrudes downward along the height direction of the device body 100. The interface includes a first interface 120, which is disposed on the top of the device body 100 and recessed downward along the height direction of the device body 100. The first connector 110 of one of two adjacent device bodies 100 is inserted into the first interface 120 of the other adjacent device body 100.

[0065] In this embodiment, the first plug portion 110 protrudes downward along the height direction of the device body 100, and the first plug interface 120 is recessed downward along the height direction of the device body 100, so that the device body 100 having the first plug interface 120 can support the device body 100 having the first plug portion 110.

[0066] It should be noted that this embodiment does not limit the cross-sectional shape of the first plug-in portion 110 and the cross-sectional shape of the first plug-in interface 120, and can be adjusted according to specific needs. For example, the cross-sectional shape of the first plug-in portion 110 is triangular, rectangular or hexagonal, and the cross-sectional shape of the first plug-in interface 120 is correspondingly triangular, rectangular or hexagonal.

[0067] For other specific implementations, please refer to Figure 3 The connector includes a second connector 130, which is disposed on the side of the device body 100 and is T-shaped. The interface includes a first interface 120, which is disposed on the side of the device body 100 and is T-shaped. A first connector 110 of one of two adjacent device bodies 100 is inserted into the first interface 120 of the other adjacent device body 100.

[0068] In this embodiment, the T-shaped second plug portion 130 and the T-shaped second plug interface 140 are matched and connected, which can limit the relative displacement of two adjacent device bodies 100 in the horizontal direction, so as to achieve a more stable connection.

[0069] Related technology provides a drainage device including a drainage tube, a drainage bag, and a paperclip. One end of the drainage tube is inserted into the drainage site of the human body, and the other end of the drainage tube is connected to the drainage bag. The drainage bag is fixed to a medical bed by the paperclip.

[0070] However, in some situations, such as when the patient turns over actively or passively, the drainage tube is pulled by force, which can easily lead to dislodgement, causing problems such as wound pain and discomfort, local wound infection, and re-insertion of the tube. This not only increases perioperative risks but can also cause physical discomfort.

[0071] Furthermore, leaving the drainage tube in place for too long makes it difficult to manage multiple drainage tubes.

[0072] To address the aforementioned technical problems, embodiments of this application provide a device for fixing a drainage device. Figure 4 This is a schematic diagram of the structure of the fixing device 10 for the drainage device. Figure 5 This is a structural schematic diagram of fastener 400.

[0073] Specifically, please refer to Figure 2 and Figure 4 The fixing device 10 of the drainage device includes a device body 100; a positioning member 200, which is disposed on the device body 100 and has a positioning hole 210 for the drainage tube 20 of the drainage device to pass through; and a blocking member 300, which is disposed on the device body 100 and is used to support the drainage tube 20 so that the drainage tube 20 is bent.

[0074] The fixing device 10 of the drainage device provided in this application embodiment has a device body 100, which is the basic structure of the entire fixing device 10 and can provide an installation and support foundation for other components of the fixing device 10.

[0075] By providing a positioning member 200 on the device body 100, and having a positioning hole 210 on the positioning member 200, when the drainage tube 20 of the drainage device is inserted into the positioning hole 210, the drainage tube 20 can be fixed on the device body 100, thus preventing the drainage tube 20 from shifting.

[0076] By providing a blocking member 300 on the device body 100, when the drainage tube 20 is confined on the device body 100, the drainage tube 20 abuts against the blocking member 300. The blocking member 300 can support the drainage tube 20 and guide the drainage tube 20 so that the drainage tube 20 is bent.

[0077] The curved drainage tube 20 has a buffering effect. When the drainage tube 20 is pulled under the action of external force, the external force is first applied to the curved part of the drainage tube 20. The direction of the force changes, and the direct pulling force is converted into a force that straightens the curved part, rather than being applied directly to the drainage site inserted into the human body, which makes it less likely to cause the tube to fall out.

[0078] Furthermore, the curved portion of the drainage tube 20 is housed on one side of the blocking member 300, resulting in a shorter length of the drainage tube 20 exposed outside the fixing device 10, which is beneficial for the installation and management of the drainage tube 20.

[0079] Furthermore, compared to related technologies that use paperclips to fix the drainage bag and drainage tube, this embodiment does not use paperclips, thus avoiding needlestick injuries.

[0080] The preferred technical solution of the fixing device 10 of the drainer according to the present application embodiment is described below with reference to the accompanying drawings.

[0081] In this embodiment, the device body 100 is a transparent acrylic sheet.

[0082] The transparent acrylic sheet has good structural strength, making it easy to support other components of the drainage device. Furthermore, the transparent acrylic sheet has a certain degree of transparency, allowing the operator to easily observe the flow of body fluids within the drainage tube.

[0083] In some embodiments, please continue reading Figure 2 and Figure 4 The fixing device 10 of the drainage device also includes a fixing member 400, which is used to be sleeved on the drainage tube 20 and inserted into the positioning hole 210.

[0084] By setting a fixing member 400, which is sleeved on the drainage tube 20 and inserted into the positioning hole 210, the drainage tube 20 can be stably fixed in the positioning hole 210 to a certain extent, thereby reducing the possibility of poor drainage or blockage caused by displacement of the drainage tube 20.

[0085] Furthermore, when the drainage tube 20 is pulled, the fixation member 400 can alert the patient so that the pulling of the drainage tube 20 can be stopped in time. Specifically, when the drainage tube 20 is pulled, the drainage tube 20 causes the fixation member 400 to disengage from the positioning hole 210, and the patient can feel the change in tension when the fixation member 400 disengages from the positioning hole 210.

[0086] In other embodiments, please continue to refer to Figure 2 and Figure 4 At least part of the blocking member 300 is along the insertion direction of the fixing member 400 (e.g. Figure 2 The direction A) is set on one side of the positioning element 200.

[0087] In this embodiment, the blocking member 300, which is disposed on one side of the positioning member 200 along the insertion direction A of the fixing member 400, abuts against the drainage tube 20, so that the drainage tube 20 is bent. This makes the fixing member 400 and the bent drainage tube 20 together constitute a dual protection mechanism.

[0088] When the drainage tube 20 is pulled, the fixing component 400 can remind the patient so that the patient can stop pulling the drainage tube 20 in time.

[0089] Because part of the drainage tube 20 is bent under the action of the blocking member 300, the bent drainage tube 20 has a buffering effect. When the external force continues to act, even if the fixing member 400 is dislodged from the positioning hole 210 under the action of the external force, the bent part of the drainage tube 20 can still withstand part of the external force and absorb part of the energy through deformation (converting the direct tensile force into a force that straightens the bent part). Therefore, the external force does not directly act on the drainage site inserted into the human body, and it is not easy to cause the tube to dislodge.

[0090] In some other embodiments, the fastener 400 is interference-fitted with the positioning hole 210.

[0091] The essence of interference fit is to create a controllable frictional force between the fixing member 400 and the positioning hole 210. When no external force acts on the fixing member 400 or the external force acting on the fixing member 400 is small, the fixing member 400 can be stably set in the positioning hole 210; when a larger external force acts on the fixing member 400, the fixing member 400 can disengage from the positioning hole 210. Specifically, when the drainage tube 20 is not subjected to external force or the external force on the drainage tube 20 is small, the drainage tube 20 can be stably connected to the device body 100 through the fixing member 400, and the drainage tube 20 will not be pulled; when the drainage tube 20 is subjected to a larger external force, the drainage tube 20 is pulled, and the drainage tube 20 can drive the fixing member 400 to disengage from the positioning hole 210, so that the bent part of the drainage tube 20 can be buffered from external force and prevent the tube from coming off.

[0092] For some specific implementation methods, please refer to [link / reference]. Figure 2 and Figure 4 There are two blocking elements 300, which are respectively set on both sides of the positioning element 200.

[0093] In this embodiment, two blocking members 300 are respectively disposed on both sides of the positioning member 200. The blocking members 300 can block the drainage tube 20 on both sides of the positioning member 200, which not only makes the length of the curved drainage tube 20 longer and the safety higher, but also allows the drainage tube 20 to be stored, making it convenient for the layout and management of the drainage tube 20.

[0094] In some embodiments, please refer to Figure 5 The fastener 400 is an elastic member and has: a tube hole 410 for the drainage tube 20 to pass through; and a plug hole 420 that penetrates the side wall of the fastener 400 and connects the tube hole 410 with the outside of the fastener 400.

[0095] By making the fastener 400 an elastic element, it becomes deformable and resilient, allowing it to adapt to drainage tubes 20 of different diameters. Furthermore, the elastic fastener 400 can slightly deform to fit the hole diameter when inserted into the positioning hole 210, and then return to its original shape after insertion to fit tightly against the hole wall. Therefore, making the fastener 400 an elastic element not only enhances its fixing effect but also improves the versatility of the fixing device 10, making it suitable for drainage tubes 20 of various specifications.

[0096] By providing the tube hole 410, the fixing member 400 can provide an installation channel for the drainage tube 20, which can both fix the drainage tube 20 and ensure the normal flow of body fluid in the drainage tube 20.

[0097] By providing a plug hole 420, the drainage tube 20 can be directly inserted into the tube hole 410 from the side of the fixing member 400. Compared with fitting the fixing member 400 from the end of the drainage tube 20, this embodiment simplifies the installation process of the drainage tube 20.

[0098] In some embodiments, please refer to Figure 5 The radial width of the fastener 400 gradually decreases along the insertion direction A of the fastener 400.

[0099] When the fastener 400 is inserted into the positioning hole 210, the radial width of the fastener 400 and the positioning hole 210 fit from loose to tight, which is more conducive to the connection between the fastener 400 and the positioning hole 210.

[0100] Specifically, in the initial stage of insertion, the smaller radial width allows the fastener 400 to be quickly aligned and enter the positioning hole 210, reducing the difficulty of operation.

[0101] As the fastener 400 continues to be inserted, its radial width gradually increases, and its fit with the positioning hole 210 gradually tightens. This progressive tightening process helps to achieve a more stable fixing effect.

[0102] In the embodiments of this application, please refer to Figure 4 The positioning element 200 also has a through hole 220, which penetrates the side wall of the positioning element 200 and connects the positioning hole 210 with the outside of the positioning element 200. The through hole 220 is used for the drainage tube 20 to pass through.

[0103] In some scenarios, a drainage tube 20 is already inserted into the area of ​​the patient's body requiring drainage, and the drainage tube 20 is in a drainage state. However, the sidewall of the positioning hole 210 on the positioning component 200 is a closed structure, meaning the drainage tube 20 can only be inserted into the positioning hole 210 through its opening, making installation inconvenient or even difficult. In this embodiment, by providing a through hole 220 that penetrates the sidewall of the positioning component 200 and connects the positioning hole 210 to the outside of the positioning component 200, the drainage tube 20 can pass through the through hole 210 from the outside of the positioning component 200 and enter the positioning hole 210. Regardless of whether the drainage tube 20 is in a drainage state, it can be easily and conveniently installed into the positioning hole 210.

[0104] In other embodiments, please refer to Figure 2 and Figure 4 The blocking member 300 is a baffle protruding from the device body 100. The baffle is curved and is used to support the drainage tube 20.

[0105] In this embodiment, because the baffle is curved, when the drainage tube 20 comes into contact with the baffle, the baffle supports the drainage tube 20 and causes the drainage tube 20 to be curved, thereby achieving the buffering effect of the drainage tube 20. Furthermore, the protruding baffle structure is simple, easy to manufacture and install, and can reduce production costs.

[0106] In some embodiments (not shown in the figures of this embodiment), the blocking member 300 is a groove provided on the device body 100, the groove wall is curved, and the groove is used to support the drainage tube 20.

[0107] In this embodiment, the groove defines a receiving area on the device body 100. This receiving area is used to receive the drainage tube 20, and the volume of the receiving area is larger than that of the drainage tube 20, so that the drainage tube 20 located within the receiving area can be changed from a curved shape to a straight shape. The groove wall is curved. When the drainage tube 20 abuts against the groove wall, the groove wall supports the drainage tube 20 and causes the drainage tube 20 to be curved, thereby achieving a buffering effect on the drainage tube 20. Furthermore, setting the blocking member 300 as a groove can also reduce costs and weight.

[0108] It should be noted that the embodiments of this application do not limit the specific shape of the groove wall and the baffle. For example, the shape of the groove wall and the baffle can be arc-shaped or wavy.

[0109] In some embodiments, please refer to Figure 2 and Figure 4The fixing device 10 of the drainage device also includes: a first hook 500 and a second hook 600. The first hook 500 and the second hook 600 are both provided on the device body 100. The first hook 500 and the second hook 600 are respectively provided on both sides of the positioning member 200. The first hook 500 is used to support the device body 100, and the second hook 600 is used to support the drainage bag 30 of the drainage device.

[0110] The first hook 500 is used to support the device body 100, which can be hung at a preset position, such as the bed board, bed frame, or railing of a medical bed. By setting the first hook 500, the fixing device 10 can be flexibly adjusted in height and position to meet the needs of different patients.

[0111] In other embodiments, the fixing device 10 of the drainage device further includes at least one mounting member 700 for mounting an identification element of the drainage device, the identification element for identifying drainage tube information, the drainage tube information including at least one of drainage tube type and drainage tube expiration period.

[0112] In a medical setting, clear labeling can help operators quickly identify different types of drainage tubes20, thereby improving work efficiency.

[0113] The marking of the expiration date of the drainage tube is directly related to patient safety. Using the drainage tube 20 beyond its expiration date may lead to infection. By setting the installation label on the mounting bracket 700, the operator can replace the drainage tube 20 in a timely manner, maintaining optimal treatment results.

[0114] It should be understood that the embodiments of this application are not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
