[0030] <Overall Structure>

[0031] like Figures 1 to 13 As shown in , an embodiment of the present invention provides a medical hanging clamp, comprising: a pair of clamping jaws 01 , a sleeve 02 provided with a guide groove 0202 , a hook 04 , and a push-pull portion 06 cooperating with a spring 08 .

[0032] By pushing the push-pull part 06 downward along the guide groove 0202 until the barb-shaped sawtooth II 0606 disposed at the lower end of the push-pull part 06 meshes with the barb-shaped sawtooth I 0203 disposed at the lower part of the sleeve 02, the pair of clamping jaws 01 can be driven to complete the action from opening to clamping. Conversely, the push-pull part 06 can be pushed downward continuously to make the barb-shaped sawtooth II 0606 continue to move downward and withdraw from the meshing with the barb-shaped sawtooth I 0203. When the barb-shaped sawtooth II 0606 contacts the housing 0204 below the barb-shaped sawtooth I 0203, the push-pull part 06 will snap back to the upper side due to the reverse thrust of the spring 08, driving the pair of clamping jaws 01 to complete the action from clamping to opening.

[0033] <Detailed structure>

[0034] like Figure 2As shown, the sleeve 02 has a shell 0204, and a guide groove 0202 in the form of a rectangular groove is provided in the upper middle position of the front side of the shell 0204 along the up-down direction, and two guide grooves 0201 are symmetrically provided at the upper positions on both sides of the guide groove 0202, and the two guide grooves 0201 are both configured to gradually approach the guide groove 0202 in an inclined manner as going from the top to the bottom and extend parallel to the guide groove 0202 at the inflection point, that is, the inclined part and the parallel part are continuously formed. The guide groove 0202 and the guide groove 0201 both penetrate the front side of the shell 0204 in the form of a slot, for example.

[0035] At the lower front part of the housing 0204, i.e., at the lower side of the guide groove 0202, there are multiple rows of groove-shaped barbed saw teeth Ⅰ0203, i.e., Fig.13 As shown, the barb teeth extend obliquely downward relative to the normal direction of the front side of the housing 0204. The barb-shaped sawtooth I 0203 is embedded inwardly into the front side of the housing 0204, and the tip of the barb-shaped sawtooth I 0203 is flush with the front side of the housing 0204 or slightly lower than the front side of the housing 0204.

[0036] A predetermined distance is left between the bottom end of the barb-shaped sawtooth Ⅰ0203 at the bottom and the adjacent front side of the housing 0204. That is, below the barb-shaped sawtooth Ⅰ0203 at the bottom, there is a front side of the housing 0204 for assisting and ensuring that the barb-shaped sawtooth Ⅱ0606 is disengaged from the barb-shaped sawtooth Ⅰ0203 when it continues to move downward. Preferably, a relatively raised trapezoidal ramp 0210 is also provided there, so that the barb-shaped sawtooth Ⅱ0606 can smoothly climb up the vertical plane of the ramp 0210 along the slope surface of the ramp 0210 (the slope surface is preferably continuous with the tooth groove surface of the barb-shaped sawtooth Ⅰ0203 at the bottom to play a guiding role) when it continues to move downward, thereby forcing a gap to be formed between the barb-shaped sawtooth Ⅱ0606 and the front side of the housing 0204 together with the barb-shaped sawtooth Ⅰ0203, so as to facilitate the upward rebound action of the push-pull part 06 without being interfered by hooking.

[0037] like Figure 3 As shown, the bottom of the sleeve 02 is a bottom plate 0208, and a suspension structure such as a U-shaped rod 0205 is connected below the bottom plate 0208. A circular hole Ⅰ0206 is provided at the bottom of the U-shaped rod 0205. A gravity sensing tube 03 is installed above the circular hole Ⅰ0206 (see Fig.10 ), a conical spring 0301 is installed inside the gravity sensing tube 03.

[0038] like Figure 7 , 8As shown, a hook 04 is installed below the U-shaped rod 0205, and the hook 04 has a connecting rod 0401. A threaded hole Ⅰ0404 is provided inside the connecting rod 0401. A lifting ring 0402 is connected below the connecting rod 0401. The notch of the lifting ring 0402 is provided with an elastic plate 0403. One end of the elastic plate 0403 is fixed to one end of the notch of the lifting ring 0402 (for example, by bonding or biased hinge), and the other free end of the elastic plate 0403 is placed on the inner side of the notch of the lifting ring 0402, and an outward force can be applied to the inner side of the notch of the lifting ring 0402.

[0039] like Figure 4 As shown, two relatively parallel slots 0211 are provided inside the sleeve 02, the top of the slot 0211 is aligned with the top of the housing 0204, the bottom of the slot 0211 directly extends to the top of the bottom plate 0208 in the sleeve 02, and the size of the slot 0211 is formed so that the two ends of the strip plate 0601 can be embedded in the slot 0211 and move up and down synchronously without deflection and shaking in all directions. Preferably, the two slots 0211 are parallel to the guide slot 0202.

[0040] like Figure 5 As shown, the clamping jaw 01 has a clamping jaw arm 0102, the upper end of the clamping jaw arm 0102 is wider and has a bar tooth 0101 formed on the side, the lower end of the clamping jaw arm 0102 is thinner and has a guide column 0103 on the front, the guide column 0103 is fixed to the clamping jaw arm 0102 by bonding (or threaded hole connection, etc.), and the pivot 0104 is separated from the guide column 0103 and fixed to the bottom end of the front side of the clamping jaw arm 0102 by bonding (or threaded hole connection, etc.).

[0041] like Figure 6 As shown, the push-pull part 06 has a strip plate 0601, on which two circular holes II0602 are symmetrically distributed, an L-shaped push-pull arm 0604 is installed on the front of the strip plate 0601, and the upper end of the L-shaped push-pull arm 0604 has two threaded holes II0603, and two bolts II0607 are respectively passed through the corresponding threaded holes II0603 and screwed into the front of the strip plate 0601 (refer to Fig.11 ), so that the L-shaped push-pull arm 0604 and the strip plate 0601 are fixed to each other. A stopper 0605 is installed (for example, by bonding or bolting) on ​​the front of the L-shaped push-pull arm 0604, and a barbed sawtooth II 0606 is formed on the back of the lower end of the L-shaped push-pull arm 0604.

[0042] like Fig.11As shown, the spring 08 can be fixedly installed above the bottom plate 0208 in the sleeve 02, and the top is subjected to the pushing force of the push-pull part 06. In order to facilitate the positioning of the lower end of the spring 08, a concave-convex positioning part (not shown) of appropriate length can also be provided on the bottom plate 0208, so that the lower end of the spring 08 can be sleeved thereon. Similarly, the bottom surface of the head at the upper end of the push-pull part 06, for example, the bottom surface of the head at the connection between the L-shaped push-pull arm 0604 and the strip plate 0601, can also be provided with a corresponding positioning convex part or concave part, but it is not limited to this, and the top of the spring 08 can also be directly bonded to the bottom surface of the head, and the number and position of the spring 08 are not limited to this.

[0043] <Assembly method>

[0044] First, take out two clamping jaws 01 and the strip plate 0601 of the push-pull part 06 from the clamp parts package, then install the pivot 0104 on the clamping jaw 01 into the circular hole Ⅱ0602, and the front side of the clamping jaw arm 0102 is against the back side of the strip plate 0601, and install the retaining spring 07 on the pivot 0104 extending from the circular hole Ⅱ0602 to fix the pivot 0104 so that it can only rotate freely in the circular hole Ⅱ0602 but cannot shake axially. The pivot 0104 on the other clamping jaw 01 is also symmetrically installed in the other circular hole Ⅱ0602 and the retaining spring is clamped. In this way, a pair of clamping jaws 01 are installed symmetrically, and the strip teeth 0101 facing each other can mesh well.

[0045] Then take out the sleeve 02, fix the spring 08 (including temporary fixation) on the bottom surface of the strip plate 0601, and then put the installed clamping jaw 01 and the strip plate 0601 of the push-pull part 06 into the sleeve 02, so that the two ends of the strip plate 0601 are inserted into the slot 0211 and pushed along the slot 0211 to the inner bottom side of the sleeve 02 until the lower end of the spring 08 is fixed above the bottom plate 0208 in the sleeve 02. Since the sleeve 02 can be slightly deformed based on materials such as silicone, plastic, and stainless steel with appropriate hardness and strength, the guide column 0103 on the clamping jaw 01 can be squeezed into the guide groove 0201 in the sleeve 02 during the process of starting to slide down. At this time, the strip plate 0601 has already exerted a downward force on the spring 08 by contacting the top of the spring 08, thereby ensuring that the guide column 0103 can be pushed back to the top of the guide groove 0201 when the push-pull part 06 rebounds.

[0046] Then push the head of the upper end of the L-shaped push-pull arm 0604 from the front of the sleeve 02 ( Fig.11The L-shaped push-pull arm 0604 and the strip plate 0601 are fixed to each other. The front side of the L-shaped push-pull arm 0604 (part of the front structure is omitted for the convenience of cross-section) passes through the guide groove 0202 to contact the strip plate 0601, and two bolts II 0607 pass through the corresponding threaded holes II 0603 and are screwed into the front side of the strip plate 0601, so that the L-shaped push-pull arm 0604 and the strip plate 0601 are fixed to each other. A stopper 0605 is installed on the front side of the L-shaped push-pull arm 0604 (through bonding or bolt connection, etc.), and a barb-shaped sawtooth II 0606 is provided on the back side of the lower end of the L-shaped push-pull arm 0604. At this time, the barb-shaped sawtooth II 0606 at the lower end of the L-shaped push-pull arm 0604 is parallel to the surface of the housing 0204 and has a slight gap with the housing 0204.

[0047] The gravity sensing tube 03 is installed (for example, bonded) above the circular hole Ⅰ0206, and a conical spring 0301 is installed (for example, bonded or welded) inside the gravity sensing tube 03. The gravity sensing tube 03, the conical spring 0301 and the circular hole Ⅰ0206 are coaxial.

[0048] The threaded rod 0501 of the bolt Ⅰ05 passes through the gravity sensing tube 03, the conical spring 0301 and the circular hole Ⅰ0206 in sequence until it meshes with the threaded hole Ⅰ0404, so that the hook 04 and the U-shaped rod 0205 are connected together. At this time, the initial state is that the nut part of the bolt Ⅰ05 is embedded in the gravity sensing tube 03 and contacts the top of the conical spring 0301. The hook 04 and the bolt Ⅰ05 can rotate freely around the center line of the circular hole Ⅰ0206. In this way, a mechanical weighing unit can be formed through calibration.

[0049] <Example>

[0050] As mentioned above, the initial state of the installed clamp is that the two clamping jaws 01 are in an open state. Figure 1 As shown, hold the clamp close to the patient's clothes, and then use the thumb to push the stopper 0605 (equivalent to the driving part) on the front side of the L-shaped push-pull arm 0604 to move the L-shaped push-pull arm 0604 toward the bottom plate 0208 of the sleeve 02, and then the L-shaped push-pull arm 0604 pulls the strip plate 0601 in the slot 0211 of the sleeve 02 to move toward the bottom plate 0208, and the strip plate 0601 pulls the clamping claw 01 to move toward the bottom plate 0208, and the guide column 0103 on the strip plate 0601 will move along the guide groove 0201 from the top of the guide groove 0201 through the inclined part and the parallel part to the bottom of the guide groove 0201. During the movement, the guide column 0103 will give the clamping claw 01 a horizontal component force, so that the two clamping claws 01 move towards the state of clamping the clothes until the two clamping claws 01 are tightly bitten together.

[0051] When the thumb pushes the stopper 0605 on the front side of the L-shaped push-pull arm 0604 toward the bottom plate 0208, the thumb also applies a pressing force toward the back side of the stopper 0605. Since the barbed serration II 0606 and the barbed serration I 0203 are arranged in basically the same inclined direction, the barbed serration II 0606 can fit the barbed serration I 0203 and move toward the bottom plate 0208.

[0052] In addition, when the thumb pushes the stopper 0605 on the front of the L-shaped push-pull arm 0604 to move toward the bottom plate 0208, the strip plate 0601 continuously compresses the spring 08, and the spring 08 also gives the strip plate 0601 an increasingly greater counter-thrust. When the two clamping jaws 01 tightly clamp the clothes, the thumb presses the stopper 0605 and removes the thrust, so that the barb-shaped sawtooth II 0606 engages with the barb-shaped sawtooth I 0203. Since the spring 08 is in a compressed state, it exerts a counter-thrust on the strip plate 0601 away from the bottom plate 0208, thereby exerting a counter-thrust on the L-shaped push-pull arm 0604 away from the bottom plate 0208, so that the barb-shaped sawtooth II 0606 and the barb-shaped sawtooth I 0203 have a continuous dislocation force, so that the barb-shaped sawtooth II 0606 and the barb-shaped sawtooth I 0203 are firmly engaged together. Accordingly, the two clamping jaws 01 will continuously clamp the clothes.

[0053] In addition, when the two clamping jaws 01 tightly clamp the clothes, the extra lapels or folds can be put into the clamping jaw gap 0105, which is convenient for the user to better clamp the clothes. Figure 5 , 12 As shown, the stepped structure of a pair of clamping jaw arms 0102 with a wider upper end and a thinner lower end can be effectively utilized to simply form a clamping jaw gap 0105.

[0054] Then the user takes the drainage bag by the hanging opening close to the notch of the hanging ring 0402 and presses the elastic plate 0403 to make it spring open and hang it into the hanging ring 0402, and the elastic plate 0403 automatically springs back to its original position to seal the notch.

[0055] When there is no liquid in the drainage bag, bolt Ⅰ05 contacts the conical spring 0301 inside the gravity sensing tube 03, and this can be calibrated as the zeroing or peeling state of the weighing unit; when there is liquid in the drainage bag, bolt Ⅰ05 will generate a certain force on the conical spring 0301 through the action of gravity, and the result will be displayed through the corresponding weight dial pointer for easy observation and recording.

[0056] When the user does not use the clamp, the user can continue to push the stopper 0605 on the front of the L-shaped push-pull arm 0604 with the thumb to move toward the bottom plate 0208, so that the barb-shaped serration II 0606 continues to move toward the bottom plate 0208, and the barb-shaped serration II 0606 will fit onto the plane of the shell 0204 or the trapezoidal ramp 0210. At this time, the barb-shaped serration II 0606 will completely break away from the contact with the barb-shaped serration I 0203 and produce a certain lateral distance. At this time, the thumb is released, and the spring 08 is in a compressed state, so it will give the L-shaped push-pull arm 0604 a force in the upward direction away from the bottom plate 0208, so that the guide column 0103 will move along the guide groove 0201 from the bottom of the guide groove 0201 to the top of the guide groove 0201, which will cause the clamping jaws to open quickly, and finally the medical suspension clamp will be removed. That is, after applying a slight downward force with the thumb, releasing the thumb can cause the clamping jaws to release quickly and automatically.

[0057] <Modification>

[0058] The above shows a weighing unit that can be calibrated and weighed based on a gravity sensing tube at the connection position between the sleeve 02 and the hook 04, but it is not limited to this. For example, an electronic weighing unit based on a gravity sensor disclosed in the expired patent CN201720877477 can also be used. By setting a liquid crystal display screen 0207, a switch button, and a reset button (not shown) on the surface of the shell 0204, a controller and a button battery are installed on the inner side or back side of the sleeve 02, and a gravity sensor (not shown) is set at the connection position between the hook 04 and the U-shaped rod 0205, which is connected to the controller by wired signal. The controller communicates with the gravity sensor module and processes the weight signal, which is displayed on the display screen 0207. At the same time, the reset button status can be obtained for reset. The switch button can be selected as a self-locking button, which can turn on or off the power supply. The reset button is connected to the controller module. After pressing, the current weight is set to 0, indicating reset. The button battery provides power for the electronic weighing unit. Display screen 0207 is installed on the front side of housing 0204, for example, in the free position on both sides of guide groove 0202 and under the barbed serration I 0203, for weight monitoring.

[0059] The above Figure 4 The sleeve 02 is shown in the form of a rectangular cylindrical shell, but it is not limited thereto. A cylindrical structure with equal sides and rounded corners can also be used, as long as the push-pull part 06 can be pushed and pulled along the guide groove 0201 and installed inside the sleeve. Figure 4 As can be seen from (B), an avoidance groove 0209 is appropriately provided on the back side of the sleeve 02 as required to facilitate the inward assembly of the clamping claw arm 0102.

[0060] The above Figure 6The push-pull part 06 is shown as a separately assembled strip plate 0601 and an L-shaped push-pull arm 0604, but it is not limited to this. An integrated structure can also be used according to the applicable scene and raw material, as long as the push-pull part 06 can be easily mounted on the sleeve 02.

[0061] The above shows the split assembled block 0605 as a driving part for the operator to apply force, but it is not limited to this. It can also be integrally arranged with the L-shaped push-pull arm 0604 to form a Z-shaped rod body, for example, or a concave or convex structure suitable for finger operation can be formed at the free end of the L-shaped push-pull arm 0604.

[0062] The above shows an example in which both ends of the spring 08 are attached to the strip plate 0601 and the bottom plate 0208 respectively, but it is not limited to this. Alternatively or additionally, a groove may be formed on the back side of the shell 0204 on the front side of the sleeve 02 to hold the spring 08.

[0063] The above example cleverly utilizes the flexural properties of the L-shaped push-pull arm 0604, especially at the free end, that is, as long as it has appropriate elasticity and can be pressed into an engaged state or bounced off the front of the housing 0204, it is not limited to plastic materials.

[0064] The U-shaped rod 0205 is shown above, but it is not limited to this. Other convenient connection structures can also be used as the connection position between the sleeve 02 and the hook 04, and a mechanical or electronic weighing unit can be set here according to the usage scenario.

[0065] The two clamping jaws 01 shown above can tightly clamp any part of the clothes, such as the collar, cuffs, lapels, buttonholes, folded clothes, etc. The clamping jaw gap 0105 is also particularly suitable for directly overlapping and hanging on any other supporting parts available on site, such as an infusion stand, an operating table, etc., and directly plays the role of an upper hook, and at this time, the two clamping jaws 01 do not need to clamp the intermediate medium. The configuration of the clamping jaws and the clamping jaw gap is not limited to the figure, and can be adjusted and adapted as needed. For example, it can also be formed into a shape similar to the upper structure of a stethoscope, with the two clamping jaws 01 corresponding to the earplug parts opposite to each other, and the clamping jaw gap 0105 corresponding to the part between the two long ear tubes, so that a larger gap can be formed to be used as a hook space.

[0066] The electronic weighing unit shown above can accurately monitor dynamic weight data in real time and continuously. However, it is not limited to this. For example, a drainage volume data acquisition unit can be additionally set up, with a built-in control module, storage module, communication module and power management module, etc. Among them, the control module is responsible for weight and other data processing and control data acquisition, transmission, alarm, etc., and can use a microprocessor or microcontroller such as ARM, AVR, etc., and can communicate with each module interface through a serial port such as SPI and I2C; the storage module is used to store the weight data information collected from the electronic weighing unit, for example, a storage medium such as a flash memory and an SD card can be used; the communication module is used to connect the collected drainage volume data to the network through wireless communication modules such as WiFi, BT and 3G / 4G / 5G, and complete cloud remote data storage, such as transmission to a processing device arranged in a specific network data processing center or cloud for processing; the power management module can use a rechargeable battery, etc. In this way, the data can be uploaded to the cloud or information center to provide a dynamic monitoring basis for the nursing department. A sound and light alarm unit can also be provided on the front of the housing 0204 like the display screen 0207, so as to promptly remind or upload data when the drainage volume increases suddenly, for example, when the weight increase rate during a predetermined period exceeds a set threshold. For this purpose, some modules with similar functions of the electronic weighing unit and the drainage volume data acquisition unit can be shared, integrated or separately provided on the sleeve.

[0067] In addition, an active alarm button can be set on the front of the shell 0204. In order to timely observe the changes in the color and properties of the drainage fluid, a legend corresponding to the different degrees of color and property changes of the drainage fluid is attached to the front of the shell 0204, so that the patient or the accompanying personnel can find that the color and property changes of the drainage fluid exceed the safe range and trigger the active alarm button in time. At this time, a reminder or data upload can be carried out through the corresponding alarm unit.

[0068] The device of the present invention has a simple structure and can be flexibly replaced. If one part is damaged, it is not necessary to replace the whole part, but only the damaged part. The maintenance of each component is very cheap and convenient, and the ergonomics is good. In addition, the device of the present invention is small and can be moved at hand, which is very convenient for users to carry and use at any time.
