Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an ascites drainage device. Background Art

[0002] Ascites drainage is mainly a treatment method for absorbing excess intraperitoneal fluid under pathological conditions. Its main purpose is to reduce abdominal pressure and relieve symptoms such as abdominal distension and dyspnea caused by ascites. It also helps to clarify the nature of ascites and provide a basis for the diagnosis of the disease. When performing ascites drainage, the patient is usually first given local anesthesia, and then a suitable site is selected for puncture in the abdomen. The drainage tube is inserted into the abdominal cavity to allow the ascites to flow out of the body through the drainage tube.

[0003] In order to better fix the penetration needle during drainage, the existing ascites drainage equipment usually uses adhesive tape to fix it. However, long-term fixation with adhesive tape can easily cause pain to the patient's skin when the tape is torn off during removal, and even cause partial skin damage to the patient. Therefore, a bandage method is usually used to fix the penetration needle to avoid the adverse effects of the adhesive tape.

[0004] However, when the above method is used, the size of the abdomen of the patient will change after the ascites is drained, which will cause the bandage to become loose. Although most of the bandages currently used for fixation have a certain degree of elasticity, it is difficult for the bandages on both sides used to fix the position of the penetration needle to maintain consistent contraction after a certain amount of change, resulting in a deviation in the fixed position of the penetration needle. When the deviation of the fixed position of the penetration needle is large, it will not only greatly affect the normal drainage of ascites, but also affect the safety of the patient's treatment.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0029] The first embodiment of the present application is:

[0030] See also Figures 1 to 5 ,in Figure 1 This is a schematic diagram of the overall structure of the ascites drainage device. Figure 2 It is a schematic diagram of the structure of the clamping parts. Figure 3 yes Figure 2 A magnified image of Figure 4 is a schematic diagram of the structure of the installation box 105 cut away, Figure 5 It is a schematic diagram of the structure with the sleeve frame 106 removed.

[0031] The present invention provides an ascites drainage device: comprising a drainage needle 101 and a binding assembly, wherein the binding assembly comprises an adhesive bandage 102, a buckle 103, a winding band 104, an installation box 105, a sleeve frame 106, a winding component, an installation component, a clamping component and a limiting component, wherein the winding component comprises a winding shaft 107, a connecting gear 108, a driving gear 109, a driving motor 110 and a control component, wherein the control component comprises a control template 111, a sheet pressure sensor 112 and a fitting pad 113, wherein the installation component comprises a matching adhesive bandage 114, a guide sleeve 115, a clamping component and a driving component, wherein the clamping component comprises a fixing frame 116, a clamping plate 117 and a double The screw rod 118, the driving component includes a driving gear 119, a driven gear 120 and a manual knob 121. The above-mentioned solution solves the problem that when the patient's abdomen is fixed by binding with a strap, the size of the abdomen will change after the ascites is drained, which will cause the strap to loosen. Although most of the straps used for fixation now have a certain elasticity, it is difficult for the straps on both sides used to fix the position of the penetration needle to maintain consistent contraction after a certain amount of change, which causes the fixed position of the penetration needle to shift. When the fixed position of the penetration needle shifts by a large amplitude, it will not only greatly affect the normal drainage of ascites, but also affect the safety of patient treatment.

[0032] In this embodiment, the drainage needle 101 is an existing penetrating needle body for ascites drainage. The ascites drainage of the patient can be completed by inserting the drainage needle 101 into the corresponding body position of the patient and then cooperating with the subsequent drainage absorption mechanism.

[0033] The adhesive bandage 102 is connected to the insert frame 106 through the mounting member, the buckle 103 is connected to the adhesive bandage 102 and is located on one side of the adhesive bandage 102, the roll 104 is fixedly connected to the buckle 103 and is located on one side of the buckle 103, the mounting box 105 is connected to the roll 104 through the winding member, the insert frame 106 is connected to the drainage needle 101 through the mounting member, the winding member is connected to the roll 104, the mounting member is connected to the adhesive bandage 102 is connected, the clamping member is connected to the sleeve frame 106, the limiting member is connected to the adhesive bandage 102, and the two sides of the adhesive bandage 102 are provided with Velcro matching belts for sleeve fixing, and the Velcro members arranged at the ends of the adhesive bandage 102 can sleeve the two sides of the adhesive bandage 102 on the buckle 103 of the roll 104, and the roll 104 and the buckle 103 are provided with two groups, and the two groups of the roll 104 and the buckle 103 are arranged on both sides of the installation box 105 through the winding member. The patient's abdomen can be wrapped and bound by the adhesive bandage 102 in cooperation with the two sets of the winding bands 104 and the installation box 105. In addition to the Velcro bands on both sides for bonding, the adhesive bandage 102 has a transverse through groove on the middle surface. The transverse through groove can facilitate the operator to adjust the installation position of the subsequent drainage needle 101 and its corresponding mechanism according to the actual puncture position of the patient. Both sides of the transverse through groove are soft fur surfaces for bonding, so that the user can install the drainage needle 101 through the subsequent installation component. The needle 101 is arranged on the adhesive bandage 102, so as to fix the insertion position of the drainage needle 101. The adhesive bandage 102 is not elastic, and the tightness of the entire bandage mechanism is adjusted by the winding hook provided on the installation box 105. However, when the operator puts on and binds the adhesive bandage 102 for the first time, the operator patient can adjust the binding size of the entire binding mechanism by adjusting the binding position on both sides of the adhesive bandage 102. Subsequently, the tightness of the entire bandage is adjusted by the winding component.

[0034] Secondly, the reel 107 is connected to the tape 104 and is rotatably mounted in the installation box 105; the connecting gear 108 is fixedly connected to the reel 107 and is located on one side of the reel 107; the driving gear 109 is meshed with the connecting gear 108 and is rotatably mounted in the installation box 105; the output shaft of the driving motor 110 is connected to the driving gear 109, and the driving motor 110 is fixedly mounted on one side of the installation box 105; the control component is connected to the installation box 105, and two reel 107s are provided. The two tapes 104 are respectively sleeved on the corresponding reel 107, and the two reel 107s are respectively sleeved on the corresponding reel 107. The connecting gear 108 is fixed to the end of 107, and the two connecting gears 108 are respectively meshed with the two sides of the driving gear 109, and the driving gear 109 is fixed to the output shaft of the driving motor 110. When the driving motor 110 drives the driving gear 109 to rotate, the driving gear 109 can simultaneously drive the connecting gears 108 on both sides to rotate, and then drive the winding shaft 107 to rotate through the connecting gear 108, so as to tighten or loosen the winding belt 104 on the winding shaft 107, so that after the bundling is completed, the user can directly adjust the tightness of the bundling by controlling the tightening and loosening of the winding belt 104 on both sides.

[0035] At the same time, the control template 111 is electrically connected to the drive motor 110 and installed on one side of the installation box 105; the sheet pressure sensor 112 is electrically connected to the control template 111 and installed on one side of the installation box 105; the bonding pad 113 is connected to the sheet pressure sensor 112 and is located on one side of the sheet pressure sensor 112. The control template 111 is electrically connected to the drive motor 110 and the sheet pressure sensor 112 through corresponding control circuits and transmission circuits respectively. The sheet pressure sensor 112 is a sensor that can measure the pressure distribution on the surface of an object. It usually has a thin and flat shape to facilitate installation and bonding on different surfaces. Its working principle is to convert the change of pressure into an electrical signal output based on the effects of resistance, capacitance or piezoelectricity. The detection and pressure-applying end of the sheet pressure sensor 112 is provided with the fitting pad 113. In this way, when the operator ties the entire device to the patient's body, the fitting pad 113 can transmit the pressure generated by the binding to the control template 111 through an electrical signal. Then the user can adjust the pressure range according to the actual usage through the control template 111. In this way, when the binding of the entire device becomes loose due to the factor of ascites drainage, the control template 111 can drive the drive motor 110 to synchronously reel the tapes 104 on both sides, thereby ensuring that the entire mechanism can be more tightly and stably bound and fitted, and because the two sides are tightened synchronously, there will be no large fluctuations in the positions of the corresponding components on the entire binding structure, thereby ensuring the stability of the matching position of the drainage needle 101.

[0036] In addition, the matching adhesive tape 114 is connected to the adhesive bandage 102 and is located on one side of the adhesive bandage 102; the guide sleeve 115 is connected to the insertion frame 106 and is fixedly installed on one side of the matching adhesive tape 114; the clamping component is connected to the insertion frame 106; the driving component is located on one side of the insertion frame 106, and the fixed frame 116 is fixedly connected to the insertion frame 106 and is located on one side of the insertion frame 106; the clamping plate 117 is slidably connected to the fixed frame 116 and is located on the side of the fixed frame 116 close to the drainage needle 101; the bidirectional screw rod 118 is threadedly connected to the clamping plate 117 and is rotatably installed. Installed on one side of the fixed frame 116, the driving gear 119 is rotatably connected to the fixed frame 116 and is located on one side of the fixed frame 116; the driven gear 120 is meshed with the driving gear 119 and is fixedly installed on one side of the bidirectional screw rod 118; the manual knob 121 is fixedly connected to the driving gear 119 and is located on one side of the driving gear 119, and the bottom of the matching adhesive tape 114 is provided with an adhesive plate for matching the soft hair on the surface of the adhesive bandage 102, and the middle end of the matching adhesive tape 114 is fixed with the guide sleeve 115, and the guide sleeve 115 is adapted to the matching guide groove provided on the sleeve frame 106, and the The fixing frame 116 is fixed on the top of the sleeve frame 106, and two clamping plates 117 are symmetrically slidably installed on the inner side of the fixing frame 116. At the same time, two bidirectional screw rods 118 are also provided in the fixing frame 116. The threads on both sides of the two bidirectional screw rods 118 are arranged in opposite directions. The two ends of each bidirectional screw rod 118 are respectively adapted to the threaded holes on the corresponding ends of the two clamping plates 117. The ends of the two bidirectional screw rods 118 are fixed with the driven gears 120, and the two driven gears 120 are respectively meshed with the two sides of the driving gear 119. The manual knob 121 is fixed to the end of the toothed gear so that the user can turn the manual knob 121 by turning the manual knob. The knob 121 drives the driving gear 119 to rotate, and then the rotation of the driving gear 119 synchronously drives the driven gears 120 on both sides and the bidirectional screw 118, and then the two clamps 117 on the fixed frame 116 are stably driven to each other through the synchronous driving of the bidirectional screw 118 on both sides. Since the threads on both sides of the bidirectional screw 118 have opposite rotation directions, the clamps 117 on both sides will move closer to or spread out when the bidirectional screw 118 rotates. When the two clamps 117 move closer to each other, the drainage needle 101 placed in the center hole of the insertion frame 106 can be clamped and fixed.

[0037] When an ascites drainage device of this embodiment is used, the entire mechanism is tied to the corresponding position of the patient's body through the cooperation of the adhesive bandage 102 and the two buckles 103. When the adhesive bandage 102 is first set, the user can adjust the adhesive bandage positions of the two sides of the adhesive bandage 102 according to the actual situation. After the binding is completed, the user can intuitively display the tightness of the entire binding through the adhesive pad 113 and the sheet pressure sensor 112. After that, the user sets the pressure range of the entire binding according to the actual situation of the patient and the treatment situation. When the adhesive bandage 102 is adjusted due to the patient's ascites drainage, etc. When the adhesive bandage 102 is loose, the control template 111 can control the driving motor 110 to drive the driving gear 109 according to the set pressure range, and the connecting gear 108 and the winding shaft 107 are driven to rotate by the driving gear 109, so as to retract the winding belt 104 through the rotation of the winding shaft 107, so as to ensure the stability of the entire bandage. After the adhesive bandage 102 is set, the user can first install the matching adhesive bandage 114 and the guide sleeve 115 according to the actual needle insertion position of the patient, and then the user can advance the drainage needle 101 according to the actual puncture depth. The sheathing frame 106 is sheathed on the corresponding position of the drainage needle 101, and then the manual knob 121 drives the driving gear 119 and the driven gears 120 and the bidirectional screw rod 118 on both sides to rotate, so that the two clamping plates 117 are driven to clamp and fix the drainage needle 101 by driving the bidirectional screw rods 118 on both sides, and finally the sheathing frame 106 and the adhesive bandage 102 are installed and limited by the clamping member and the limiting member. At the same time, when the sheathing frame 106 and the drainage needle 101 are installed and inserted, since the drainage needle 101 is in advance with the sheathing frame 1 06 is fixed, so when the insertion frame 106 cooperates with the guide sleeve 115 under the action of the clamping component, the drainage needle 101 can be inserted to a specified depth, and the guide sleeve 115 set in advance can also guide the insertion position of the drainage needle 101, so that the user can operate the drainage needle 101 more conveniently and quickly, and realizes that the mechanism for binding, fixing and limiting the penetration needle can be symmetrically tightened and adjusted according to the changes in the patient's abdominal condition through the provided components, and the stability of the fixed position of the penetration needle can be guaranteed when the strap is stably fitted, making it safer and more reliable in actual use.

[0038] Second embodiment:

[0039] See also Figures 6 to 8 , Figure 6 is a schematic diagram of the overall structure of the ascites drainage device of the second embodiment, Figure 7 This is a schematic structural diagram of a cutaway insertion frame 106 of the second embodiment. Figure 8 For the second embodiment Figure 7 As shown in the enlarged view of point B, the clamping member provided by the present invention includes a clamping ring 201, a sliding clamping block 202, a compression spring 203 and an extrusion component, and the extrusion component includes a rotating paddle 204, a paddle plate 205 and a pressing block 206.

[0040] Among them, the snap ring 201 is fixedly connected to the guide sleeve 115 and is sleeved on the guide sleeve 115; the sliding block 202 is slidably connected to the sleeve frame 106 and is located on the side of the sleeve frame 106 close to the guide sleeve 115; the two sides of the compression spring 203 are respectively connected to the sliding block 202 and the sleeve frame 106; the extrusion component is connected to the sleeve frame 106, the snap ring 201 is fixedly sleeved on the upper end of the guide sleeve 115, the sliding block 202 and the corresponding mechanism are provided with two groups in total, which are respectively arranged on both sides of the sleeve frame 106, the compression spring 203 is arranged in the guide groove of the sliding block 202 and the sleeve frame 106, the bottom of the sliding block 202 and the top of the snap ring 201 are provided with corresponding inclined surfaces, so that when When the operator installs the sleeve frame 106, the sliding block 202 provided in the sleeve frame 106 can be retracted through the inclined table surface at the bottom under the action of the inclined table surface at the top of the retaining ring 201. Then, after the sleeve frame 106 and the guide sleeve 115 are matched, the sliding block 202 can be reset under the action of the compression spring 203. Then, the sleeve frame 106 is limited by the cooperation between the back side of the sliding block 202 and the bottom platform of the retaining ring 201. By adopting the above-mentioned locking method, the user does not need to adjust the horizontal angle when installing the sleeve frame 106. It only needs to make the through groove of the sleeve frame 106 match with the guide sleeve 115, which makes it more convenient for the operator to install the sleeve frame 106.

The two pressing blocks 206 are respectively slidably arranged on the sleeve frame 106 on which the rotating paddle 204 is installed. In terms of position, when the user presses the pressing block 206, the inner wall of the pressing block 206 will squeeze the boss on the top of the rotating paddle 204, causing the rotating paddle 204 to rotate. When the rotating paddle 204 rotates, the driving plate 205 at the bottom of the rotating paddle 204 can pry the sliding block 202 backward, causing the sliding block 202 to retract into the matching groove of the sleeve frame 106. When the sliding blocks 202 on both sides are retracted into the corresponding matching grooves, the sleeve frame 106 can be directly pulled out from the guide sleeve 115, thereby facilitating the user to disassemble the sleeve frame 106 and the drainage needle 101.

[0042] When using an ascites drainage device of the present embodiment, the provided snap ring 201 can cooperate with the sliding block 202 and the compression spring 203 to quickly lock the insertion frame 106 and the guide sleeve 115 to limit the position, thereby facilitating the user to install and cooperate with the drainage needle 101. When the operator needs to disassemble the insertion frame 106 and the drainage needle 101, the operator only needs to press the pressing blocks 206 on both sides at the same time, and use the pressing blocks 206 to squeeze the corresponding rotating paddles 204 to rotate, and then drive the toggle plate 205 to drive the sliding block 202 through the rotation of the rotating paddle 204, so that the two sliding blocks 202 retract into the grooves that cooperate with the insertion frame 106, so that the operator can directly pull the insertion frame 106 out of the guide sleeve 115, making it more convenient for the operator to operate in practice, greatly enhancing the practicality of the entire device.
