Description

Technical Field

[0001] This invention relates to the field of medicine tube clamping technology, and in particular to a medicine tube clamping device and clamping method thereof. Background Technology

[0002] In the production process of a certain type of pharmaceutical tube, multiple tubes need to be coated with adhesive at their bottoms before proceeding to the next step. The current production process involves manually placing the tubes in a honeycomb container and then manually restraining multiple tubes while applying the adhesive. However, these pharmaceutical tubes are flammable and explosive, and they also release toxic substances. Manually restraining the tubes poses a serious threat to the lives and health of workers.

[0003] Existing clamping devices typically use jaws for clamping, which takes up considerable space and is unsuitable for applications requiring dense clamping. Furthermore, tubular polymers, especially small cylindrical ones, are characterized by thin walls, irregular deformation, and large deformation. Most existing clamps are only suitable for single items with minimal deformation, and cannot apply uniform force when clamping a large number of items with irregular and large deformations. Ordinary clamps also fail to consider the special requirements of explosion-proof environments; their materials are generally metal or plastic, making them unusable for applications requiring dense clamping of flammable and explosive chemical tubes. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a medicine tube clamping device and clamping method to solve the problem that existing clamping devices are prone to damaging medicine tubes.

[0005] The objective of this invention is mainly achieved through the following technical solutions:

[0006] A drug tube clamping device includes: an elastic expansion bladder that extends into the inside of the drug tube; the elastic expansion bladder is capable of being inflated and expanded to both sides.

[0007] Furthermore, the drug tube clamping device also includes: a support column; and an elastic dilatation bladder mounted on the support column.

[0008] Furthermore, the support column includes: a connecting part and an extension part; the connecting part is connected to the inflation device, and the extension part can extend into the inside of the drug tube; an elastic expansion bladder is installed in the extension part.

[0010] Furthermore, the elastic expansion bladder is fitted inside the support column, and the support column has slots on both sides; after being inflated, the elastic expansion bladder can extend and expand at the slots.

[0011] Furthermore, the connecting part is provided with an inflation vent, which is connected to the elastic expansion bladder.

[0012] Furthermore, a stop is provided between the connecting part and the extension part, and the diameter of the stop is larger than the inner diameter of the medicine tube.

[0013] Furthermore, the medicine tube clamping device is installed on the mounting end cover, which has multiple mounting holes; the mounting holes are threaded holes, and the connecting part has external threads, which are installed on the mounting end cover by the threads.

[0014] Furthermore, the mounting end cap is connected to the inflation device, and the air outlet pipe of the inflation device can simultaneously connect to the inflation holes of multiple support columns on the mounting end cap.

[0015] A clamping method for a drug tube clamping device includes the following steps:

[0016] Step S1: Install the connector into the mounting hole of the mounting end cap;

[0017] Step S2: Place the medicine tube on the outside of the extension;

[0018] Step S3: Inflate the elastic expansion bladder using the inflation device; after inflation, the elastic expansion bladder expands and presses against the inner wall of the drug tube, thus clamping the drug tube.

[0019] The technical solution of the present invention can achieve at least one of the following effects:

[0020] 1. The medicine tube clamping device of the present invention can be used to clamp flammable and explosive medicine tubes. When using it, only the tolerance zone of the inner diameter of the medicine tube needs to be determined to select a suitable specification.

[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0036] Example 1

[0037] A specific embodiment of the present invention discloses a medicine tube clamping device, comprising: a support column and an elastic expansion bladder 4, wherein the elastic expansion bladder 4 can extend into the inside of the medicine tube 6; and the elastic expansion bladder 4 can be inflated, and after the elastic expansion bladder 4 is inflated, it clamps the medicine tube 6 by squeezing the inner wall of the medicine tube 6.

[0038] Specifically, the support column is made of metal and is irregularly cylindrical in shape. The metal surface is nickel-plated for explosion protection. The elastic expansion bladder 4 is made of a soft, elastic material, which is explosion-proof and also has a certain degree of plasticity.

[0039] Furthermore, the elastic expansion bladder 4 is fitted onto the outside of the support column. Alternatively, the elastic expansion bladder 4 is fitted onto the inside of the support column. Preferably, the elastic expansion bladder 4 is disposed inside the support column; specifically, the elastic expansion bladder 4 is fitted into the internal cavity of the support column, and the support column has slots on both sides; the elastic expansion bladder 4, after being inflated, can extend and expand at the slots.

[0040] like Figure 1 The diagram shown is a schematic of the drug tube clamping device of the present invention.

[0041] The elastic expansion bladder 4 is soft when uninflated, but expands and becomes elastic when inflated. The protrusions on the outer edge of the elastic soft material are symmetrically distributed and embedded in the grooves of the support column. After inflation, the outer edge of the elastic soft material expands and contacts the inner diameter of the drug delivery tube, achieving a locking mechanism. In actual manufacturing, the outer edge of the elastic soft material is installed into the support column through the inflation vent, ensuring that the protrusions on the outer edge of the elastic soft material are engaged within the grooves of the support column.

[0042] like Figure 2 The diagram shown illustrates the operating principle of the drug tube clamping device of the present invention.

[0043] The main body of the drug delivery tube clamping device consists of a metal support column and an elastic expansion bladder 4 made of elastic composite material. The elastic expansion bladder 4 is located inside the support column, and its two side protrusions are engaged in slots on both sides of the support column. The elastic expansion bladder 4 is made of elastic composite material and has symmetrical protrusions. An inflation vent 101 is opened in the middle of the metal support column, through which air can be injected into the elastic expansion bladder 4 of the elastic composite material to control the expansion and contraction of the elastic expansion bladder 4.

[0044] An external air source can inflate the elastic expansion bladder 4 through the inflation port. After inflation, the two protrusions of the elastic expansion bladder 4 expand on the grooves of the support column, clamping the inner hole of the medicine tube 6 to form a clamping force. When release is needed, simply control the air source pressure. The size of the flange of the elastic expansion bladder 4 must be limited to a certain range according to the size of the inner diameter. When using it, the appropriate size should be selected according to the inner diameter of the medicine tube and the manufacturing tolerance of the elastic composite material.

[0045] Furthermore, the support column includes: a connecting part 1, a stop part 2, and an extension part 3; the support column is divided into three sections from left to right: the left section is the connecting part 1 with mounting threads, the middle section is the stop part 2 with a shoulder that separates the left and right sections, and the right section is the extension part 3 that can extend into the medicine tube 6.

[0046] Specifically, the connecting part 1 is connected to the inflation device, the stop part 2 can stop the travel of the medicine tube 6 as it is fitted onto the support column, and the extension part 3 can extend into the medicine tube 6; the elastic expansion bladder 4 is fitted inside the extension part 3. The connecting part 1 is provided with an inflation vent 101, which communicates with the elastic expansion bladder 4. The stop part 2 is provided between the connecting part 1 and the extension part 3, and the diameter of the stop part 2 is larger than the inner diameter of the medicine tube 6, which can prevent the end of the extension part 3 from contacting the bottom of the medicine tube 6.

[0047] The support column of the medicine tube clamping device of the present invention includes a connecting part 1 with mounting threads on the far left, an extension part 3 that can extend into the medicine tube 6 on the right end, and a stop part 2 on the middle shoulder that separates the left and right sections.

[0048] The support column of the drug tube clamping device of the present invention is fixed and positioned by the mounting thread of the connecting part 1. The end of the extension 3 at the right end of the support column is provided with a bullet-shaped transition surface, or the end of the extension 3 is provided with a rounded corner. The bullet-shaped transition surface or the rounded corner can serve as a mounting stop to guide the axial movement of the tubular polymer, i.e., the drug tube, and can pre-correct deformed tubular polymer.

[0049] Furthermore, by controlling the inflation and deflation of the inflation port 101, the elastic expansion bladder 4 inside the extension 3 is controlled to expand or contract, thereby achieving the switching of clamping and releasing the medicine tube 6. In addition, by adjusting the inflation pressure of the inflation device, the external air source pressure is externally adjustable, thereby achieving the adjustment of the clamping force on the medicine tube 6.

[0050] Furthermore, such as Figure 3 The diagram shows the use of the medicine tube clamping device of the present invention. The medicine tube clamping device is installed on the mounting end cover 5, which has multiple mounting holes. The mounting holes are threaded holes, and the connecting part 1 has external threads. The connecting part 1 is installed on the mounting end cover 5 by the threads.

[0051] Specifically, the mounting end cover 5 is circular, and multiple mounting holes are provided on the mounting end cover 5. The multiple mounting holes are evenly distributed on the mounting end cover 5; or the mounting end cover 5 is rectangular, and the multiple mounting holes are distributed in an array on the mounting end cover 5.

[0052] Furthermore, the mounting end cap 5 is connected to the inflation device, and the air outlet pipe of the inflation device can simultaneously communicate with the inflation holes 101 of multiple support columns on the mounting end cap 5.

[0053] In one specific embodiment of the present invention, the air tube of the inflation device is sealed to the mounting end cap 5, and the air outlet of the air tube of the inflation device is connected to the inflation air hole 101 of the drug tube clamping device. Furthermore, the air pressure inside the elastic expansion bladder 4 is controlled by adjusting the air pressure of the air tube of the inflation device. By inflating or deflating the elastic expansion bladder 4 of the drug tube clamping device using the inflation device, multiple drug tube clamping devices can simultaneously clamp or release multiple drug tubes 6.

[0054] In another specific embodiment of the present invention, such as Figure 4 , Figure 5 As shown, a pressure relief mechanism 8 is provided on the stop part 2. The pressure relief mechanism 8 is connected to the elastic expansion bladder 4. The pressure relief mechanism 8 can release the air from the elastic expansion bladder 4, thereby releasing the medicine tube 6.

[0055] Furthermore, the pressure relief mechanism 8 includes: a pressure relief chamber 802, an elastic support member 803, a sealing gasket 804, a vent, a connecting rod 805, and a pressure relief button 806.

[0056] The vent hole connects the pressure relief chamber 802 to the external space. A sealing gasket 804 and an elastic support 803 are disposed inside the pressure relief chamber 802. The sealing gasket 804 seals the vent hole, and the elastic support 803 is disposed between the sealing gasket 804 and the bottom of the pressure relief chamber 802. The sealing gasket 804 blocks the vent hole under the support of the elastic support 803. A connecting rod 805 is disposed in the vent hole and can slide relative to it. A pressure relief button 806 is provided at the upper end of the connecting rod 805, and the lower end of the connecting rod 805 is connected to the sealing gasket 804.

[0057] When using:

[0058] Pressing the pressure relief button 806 causes the connecting rod 805 to move downwards, which in turn causes the sealing gasket 804 to move downwards while simultaneously compressing the elastic support 803. After the sealing gasket 804 moves downwards, the vent opens, and the gas inside the elastic expansion bladder 4 escapes. The clamping force of the elastic expansion bladder 4 on the medicine tube 6 decreases or disappears, allowing the medicine tube 6 to be removed from the medicine tube clamping device. Releasing the pressure relief button 806 causes the sealing gasket 804 to reset under the action of the elastic support 803, re-blocking the vent, and the elastic expansion bladder 4 to resume its clamping function.

[0059] Furthermore, such as Figure 5 As shown, the pressure relief chamber 802 is connected to the elastic expansion bladder 4. Specifically, a pressure relief air pipe 801 is provided on the stop part 2. The two ends of the pressure relief air pipe 801 are connected to the pressure relief chamber 802 and the elastic expansion bladder 4 respectively, so that the pressure relief mechanism 8 can relieve the pressure of the elastic expansion bladder 4 and then remove the single drug tube 6.

[0060] The drug tube clamping device of the present invention can inflate or depressurize all elastic expansion bladders 4 by changing the inflation or depressurization state of the external air source, i.e., the inflation device; and can depressurize a single elastic expansion bladder 4 by pressing the depressurization button on an individual support column.

[0061] Furthermore, a pressure sensor 7 is installed between the inflation port 101 and the elastic expansion bladder 4. When the pressure inside the elastic expansion bladder 4 reaches the preset pressure, a pressure signal is sent through the pressure sensor 7 to prevent the elastic expansion bladder 4 from applying excessive pressure to the inner wall of the medicine tube 6, which could damage the medicine tube 6.

[0062] During implementation:

[0063] The drug tube clamping device of the present invention is mounted on the mounting end cap 5 via the mounting threads on the connecting part 1. The mounting end cap 5 has multiple threaded holes, thus allowing the installation of multiple drug tube clamping devices to achieve the clamping of multiple drug tubes 6. During the clamping process, the drug tube is guided to move axially through the bullet-shaped transition surface at the right end of the support column, while pre-correcting any deformed drug tubes. The elastic expansion bladder of the elastic composite material is then inserted into the inside of the drug tube 6. The clamping is achieved after the elastic expansion bladder 4 is inflated. The inflation pressure of the elastic expansion bladder 4 can be adjusted according to the actual situation.

[0064] The technical solution provided in this embodiment has at least one of the following beneficial effects:

[0065] The drug tube clamping device of the present invention has multiple support columns that can be installed on the mounting end cap 5, which can be used in situations requiring dense clamping and can clamp multiple drug tubes simultaneously in a small space. Furthermore, it is very convenient to install and disassemble, facilitating maintenance and replacement.

[0066] The drug tube clamping device of the present invention, since the elastic expansion bladder 4 clamps the drug tube 6 with flexible support, can avoid damage to the drug tube 6 and has explosion-proof characteristics, and can be used in occasions where flammable and explosive drug tubes need to be clamped.

[0067] The drug tube clamping device of the present invention has an inflation hole in the middle of the connecting part. The elastic expansion bladder 4 can be inflated through the inflation hole. The expansion or contraction of the elastic expansion bladder 4 can achieve clamping or loosening of the drug tube, realizing external control of the clamping and loosening of the drug tube clamping device. At the same time, the inflation pressure of the elastic expansion bladder 4 can be adjusted according to the different clamping forces required.

[0068] Example 2

[0069] A specific embodiment of the present invention provides a clamping method for the drug tube clamping device in Embodiment 1, characterized by comprising the following steps:

[0070] Step S1: Install the connecting part 1 of the support column into the mounting hole of the mounting end cover 5; specifically, the connecting part 1 is installed in the mounting hole by means of threaded coupling.

[0071] Step S2: Place the medicine tube 6 on the outside of the extension 3 of the support column; that is, place it on the outside of the elastic expansion bladder 4.

[0072] Step S3: Inflate the elastic expansion bladder 4 using the inflation device; after inflation, the elastic expansion bladder 4 expands and presses against the inner wall of the medicine tube 6, thus clamping the medicine tube 6.

[0073] In step S3, when the inflation device inflates the elastic expansion bladder 4 through the inflation port 101, the protrusions on both sides of the elastic expansion bladder 4 extend out from the slots on both sides of the support column and expand, as shown in the figure. Figure 2 As shown.

[0074] Further, in step S4: when it is necessary to remove the clamped medicine tube 6, the air pressure of the external air source (inflator) can be adjusted to cause the elastic expansion bladder 4 to contract, thereby reducing or eliminating the clamping force of the elastic expansion bladder 4 on the inner wall of the medicine tube 6, and the medicine tube 6 can be removed.

[0075] or,

[0076] When the drug tube clamping device is equipped with a pressure relief mechanism 8: Pressing the pressure relief button 806 causes the connecting rod 805 to push the sealing gasket 804 downward, eliminating the blockage of the vent hole above the pressure relief chamber 802 by the sealing gasket 804, allowing the gas inside the elastic expansion bladder 4 to be discharged through the vent hole. The internal air pressure of the elastic expansion bladder 4 decreases and the volume of the elastic expansion bladder 4 contracts, reducing or eliminating the clamping force of the elastic expansion bladder 4 on the inner wall of the drug tube 6, and the drug tube 6 can be removed. At this time, the elastic support 803 below the sealing gasket 804 is in a compressed state.

[0077] Furthermore, when the pressure relief button 806 is released, the sealing gasket 804 will move upward under the elastic force of the elastic support 803 below, automatically sealing the vent hole; after the sealing gasket 804 seals the vent hole, the elastic expansion bladder 4 can re-inflate and expand, thereby clamping the medicine tube 6.

[0078] Compared with the prior art, the technical solution provided in this embodiment has at least one of the following beneficial effects:

[0079] 1. The drug tube clamping device of the present invention has the advantages of small size and convenient installation;

[0080] 2. The drug tube clamping device of the present invention is suitable for occasions where flammable and explosive drug tubes are densely distributed and require clamping.

[0081] 3. The clamping and releasing of the clamped object by the drug tube clamping device of the present invention can be controlled by external air source pressure, which is easy to achieve.

[0082] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
