Description

TECHNICAL FIELD

[0001] The utility model relates to medical technology field especially a novel head-mounted infusion device. BACKGROUND

[0002] During intravenous infusion, the drug solution that the patient needs to infuse on the same day is usually prepared and packaged in multiple infusion bags / bottles and hung on the hooks of the infusion stand. After one bottle / bag of drug solution is infused, the next bottle / bag of drug solution is usually infused by the patient informing the medical staff to change, which increases the burden of the medical staff. Moreover, the infusion bottle or infusion bag needs to be supported by the infusion stand, which makes it inconvenient for the patient to walk, use the toilet, and other activities. At the same time, during intravenous infusion, close contact is formed between multiple patients in the same infusion room, and cross infection between multiple patients is likely to occur, thereby increasing the risk of disease transmission. Moreover, multiple patients simultaneously receiving infusion treatment in a fixed space also easily causes noise and crowding, which brings discomfort and psychological pressure to the patients and may increase the recovery time of the patients.

[0003] There are some wearable or movable infusion devices in the prior art, which enable the patient to move relatively freely without holding the infusion bottle or infusion bag. For example, a head-mounted infusion device, but the head-mounted infusion device in the prior art can only carry one bottle / bag of drug solution, and does not fundamentally solve the technical problems of free movement, freeing the hands, and reducing the replacement of liquid during infusion, which is not friendly to the patient and the medical staff.

[0004] Moreover, the infusion container of the head-mounted infusion device is usually worn on the patient's head, and the support height of the head-mounted infusion container is relatively low compared to the support height of the infusion bag of the conventional infusion stand, and the gravitational potential energy obtained is smaller than that of the infusion bag supported by the conventional infusion stand. Therefore, in the latter half of the infusion, especially when the infusion of the drug solution is about to end, the inside of the infusion container is prone to wrinkles or unevenness due to the collapse of the infusion container, which may cause the remaining drug solution to accumulate at the bottom of the infusion container, the flow kinetic energy is insufficient, resulting in a decrease in infusion flow rate or even no flow, and the drug solution retained in the collapsed infusion container also causes waste of drug solution, which is not conducive to disease treatment.

[0005] Therefore, it is necessary to develop a novel head-mounted infusion device to solve the above problems. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0028] The technical solutions of the present application will be described clearly and completely in the following detailed description. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] Referring to the accompanying drawings Figs. 1-3 As shown in the drawings, the novel head-mounted infusion device of the present application comprises, from top to bottom, a head-mounted infusion container 1, an upper infusion hard pipe 2, a drip pot 3, a lower infusion soft pipe 4, and an infusion needle 5, the head-mounted infusion container 1 comprises a control box 6 and a plurality of annular and internally hollow container monomers 7, each container monomer 7 is arranged in layers, the control box 6 is installed at the bottom of the bottom layer container monomer 7, each container monomer 7 is provided with a liquid medicine inlet 8 and a liquid medicine outlet 9, each liquid medicine outlet 9 is connected with an infusion pipe, the infusion pipe extends into the control box 6, the infusion pipe extends out of the control box 6 after being regulated by the control box 6, and the extension end of the infusion pipe in the control box 6 is communicated with the upper infusion hard pipe 2.

[0030] Embodiment one

[0031] Referring to the accompanying drawings Fig. 1 and the accompanying drawings Fig. 2As shown, the head-mounted infusion container 1 of the present application is composed of four annular and internally hollow container units 7 stacked one on top of another. The shape of the stacked four container units 7 can be stably worn on the head of an infusion patient or an accompanying person, i.e. the size and shape of the head-mounted infusion container 1 are suitable for being worn on the head of an infusion patient or an accompanying person. In order to suit the head size of different people, the overall interior of the head-mounted infusion container 1 is hollow, which can form a shape such as a cylinder, a circular truncated cone, a circular cone or the like, for example, a hat shape. The four container units 7 are all annular and closed, with their interiors being hollow. The four container units 7 are each provided with a medicine inlet 8 and a medicine outlet 9. The medicine inlet 8 is used to add medicine into the annular and closed container unit 7, and the medicine inlet 8 is provided with a self-sealable first sealing member, i.e. a sealing plug or a sealing valve. The medicine outlet 9 includes a gradually sloping and smoothly sunken portion from the inner wall of the lowermost part of the annular and closed container unit 7, thereby forming a low point similar to a funnel shape. In this way, the medicine in the annular and closed container unit 7 can be gathered around the sunken portion.

[0032] In clinical practice, the total amount of continuous normal infusion experienced by an adult infusion patient between the time of needle insertion and needle removal within one day or 12 hours is generally below 2500 ml, usually in the range of 800 ml to 2000 ml, and most commonly around 1000 ml to 1500 ml. Therefore, the specific number of the head-mounted infusion container 1 is preferably composed of 2 to 8 annular and closed container units 7, and more preferably composed of 2 to 6 annular and closed container units 7. The volume of a single annular and closed container unit 7 is set to be between 100 ml and 600 ml, for example, 100 ml, 150 ml, 200 ml, 225 ml, 250 ml, 300 ml, 325 ml, 350 ml, 400 ml, 425 ml, 450 ml, 500 ml, 550 ml, 600 ml, etc. For a complete head-mounted infusion container 1, the volume of each annular and closed container unit 7 can be the same, different, or only partially the same. The total volume of the head-mounted infusion container of the present application is preferably in the range of 600 ml to 2600 ml, and more preferably in the range of 800 ml to 2200 ml.

[0033] In this application, each of the 9 drug outlets is connected to an infusion tube, which extends into the control box 6. After being regulated by the control box 6, the infusion tube extends out of the control box 6, and the extended end of the infusion tube from the control box 6 is connected to the upper infusion rigid tube 2. The infusion tube includes infusion branch tubes 101 and an infusion main tube 102. One end of each infusion branch tube 101 is connected to each drug outlet 9 on each container unit 7, and the other end is connected in parallel to the infusion main tube 102. That is, the infusion branch tubes 101 are arranged in parallel in the vertical direction. The drug in each container unit 7 flows from each infusion branch tube 101 into the infusion main tube 102, and the drug outlet end of the infusion main tube 102 is connected in series with the upper infusion rigid tube 2. The upper end of the upper infusion tube 2 is connected to the infusion main tube 102 extending from the control box 6 of the head-mounted infusion container 1, or directly connected to the drug outlet 8 of the container unit 7 of the head-mounted infusion container 1, and the lower end of the upper infusion tube 2 is connected to the drip chamber 3.

[0034] Regarding the drip chamber 3, in order to achieve a suitable balance between the flow of the medication and the prevention of backflow, the drip chamber 3 should have an appropriate and reasonable height. In this application, the lower limit of the height of the drip chamber 3 ("the height of the drip chamber 3" can be defined as the height of the uppermost (or lowermost) end of the drip chamber 3 relative to the ground, or the height of the center of the drip chamber 3 relative to the ground) is not lower than the height of the human heart, or not lower than the height of the arm where the needle is inserted when the patient is standing. The upper limit of the height of the drip chamber 3 is not higher than the height of the human shoulder, or not higher than the center height of the human neck. In this application, the height of the drip chamber 3 is preferably set between the height of the human heart and the height of the human shoulder.

[0035] The intravenous infusion tubing 2 of this application is entirely made of rigid materials, such as rigid plastic or metal. Fig. 1 As shown, the upper infusion tube 2 includes a downward-sloping curved section for wearing and a vertical section connecting to the drip chamber 3. This structural design allows the drip chamber 3 to be vertically suspended, facilitating the dripping of the infusion solution. Simultaneously, the rigid upper infusion tube 2 is easy to shape; for example, it can be configured to extend approximately parallel to the shoulder, ensuring that the drip chamber 3 and the lower infusion tubing 4 connected to the rigid upper infusion tube 2 do not obstruct the patient's view or hinder their hand movements. Therefore, in this application, as... Fig. 1 As shown, the rigid upper infusion tube 2 is tilted downward relative to the head-mounted infusion container 1 and extends parallel to the direction of the human shoulder when worn. The projection distance of the upper infusion tube 2 along the direction of the human shoulder is set to not exceed the width of one shoulder of the human body.

[0036] Since the medicine outlet 9 of each container unit 7 of the present application is connected with the infusion branch pipe 101 and the infusion main pipe 102, the end of the infusion main pipe 102 can be provided with an infusion main outlet valve 103, and the infusion main outlet valve 103 is provided with a self-sealing second sealing member, i.e. a sealing plug or a sealing valve. The infusion main pipe 102 is connected with the upper infusion hard pipe 2 through the infusion main outlet valve 103, i.e. the head-mounted infusion container 1 can be manufactured separately from the infusion device pipeline including the upper infusion hard pipe 2, the drip bottle 3, the infusion needle 5, etc., and the two are connected during infusion. The infusion main pipe 103 can also be directly connected with the upper infusion hard pipe 2 during manufacturing, i.e. the head-mounted infusion container 1 is integrally manufactured with the infusion device pipeline including the upper infusion hard pipe 2, the drip bottle 3, the infusion needle 5, etc. and is sterile packaged, and is directly opened for adding medicine during use.

[0037] The control box 6 is installed at the bottom of the bottommost container unit 7, and part of the infusion branch pipe 101 and the infusion main pipe 102 are arranged in the control box 6. The infusion branch pipe 101 is provided with an air inlet pipe 104 near the medicine outlet 7, and is further provided with a first speed regulating device 105 for flow interruption and / or flow rate control. The infusion branch pipe 101, the first speed regulating device 105 and the infusion main pipe 102 are integrally arranged on the control box 6, so as to control the infusion of each container unit 7. The infusion main pipe 102 is connected with the lower infusion soft pipe 4, and the end of the lower infusion soft pipe 4 is connected with the infusion needle 5. The lower infusion soft pipe 4 is further provided with a second speed regulating device 41, a filter 42, etc. The control box 6 can include a box body and a cover body (not shown in the figure) hinged to the box body. The medical staff or the infusion patient can open the cover body to control the first speed regulating device 105, so as to regulate the infusion flow rate of the corresponding infusion branch pipe 101 or stop the corresponding infusion branch pipe 101. After setting, the cover body can be closed, and the cover body protects and dustproofs the components in the box body.

[0038] Referring to the drawings, Fig. 2As shown, the inside of at least one annularly closed container unit 7 of the head-mounted infusion container 1 is provided with a flexible film 11, which divides the internal cavity of the container unit 7 into a gas chamber 111 and a liquid chamber 112, and the container unit 7 of the present embodiment is divided by the flexible film 1 into two independent chambers, i.e. the lower chamber is the liquid chamber 112 for containing the liquid medicine, and the upper chamber is the gas chamber 111 for filling the inflatable gas. The flexible film 11 can have a certain elasticity, or can have no elasticity at all. When not filled with liquid medicine, the flexible film 11 has a certain redundancy in the inside of the container unit 7; when filled with liquid medicine, under the extrusion of the liquid medicine in the liquid chamber 112, due to the certain redundancy of the flexible film 11, the redundancy allows the flexible film 11 to be completely unfolded under the extrusion of the liquid medicine to be able to adhere to the upper chamber wall of the gas chamber 111, i.e. the existence of the flexible film 11 almost has no effect on the volume of the container unit 7, or the effect is so small that it can be ignored.

[0039] And, each gas chamber 111 in each container unit 7 is connected to each other through a pipe (not shown in the figure). The head-mounted infusion container 1 is provided with an inflation valve 113 for inflating each gas chamber 111. Since each gas chamber 111 is connected to each other, only one inflation valve 113 is needed to inflate all the connected gas chambers 111. The inflation valve 113 is detachably connected to an inflatable air bag 114 which can be manually pressed. In the middle and later stage of infusion, if the drop rate is slow, or when the infusion is close to the end, since the container unit 7 will collapse after the drug liquid is reduced, causing part of the drug liquid to accumulate in the folds of the collapsed container unit 7 and not to flow normally, at this time the patient or the accompanying person can manually press the inflatable air bag 114 to inflate the gas chamber 111 of the container unit, on the one hand, this can inflate the collapsed container unit 7, the inner wall of the container unit 7 becomes smooth, which is conducive to the flow of the drug liquid. On the other hand, manual inflation can increase the internal pressure of the container unit 7, which can promote the flow of the drug liquid to the outlet. And although each gas chamber 111 of each container unit 7 is connected to each other, when inflating the gas through the inflation valve 113, only the collapsed container unit 7 will be squeezed and inflated. The container unit 7 that has not yet infused the drug liquid will not be affected because the drug liquid outlet 9 of the container unit 7 has not been opened. The inflation valve 113 is also provided with a pressure relief valve. The head-mounted infusion container 1 of the present application is placed on the head of the infusion patient or the infusion accompanying person during infusion. The overall height of the head-mounted infusion container 1 is lower than the height of the traditional infusion bottle / bag supported by the infusion stand. By providing the inflation valve 113 and the inflatable air bag 114, on the one hand, the pressure of the collapsed container is increased, thereby increasing the kinetic energy of the drug liquid, and on the other hand, the inner wall of the inflated and expanded collapsed container becomes smooth, which is also conducive to the flow of the drug liquid. It can make up for the defects of the head-mounted infusion container 1, such as small potential energy, easy accumulation of remaining drug liquid, and slow infusion flow rate compared with the traditional infusion stand. At the same time, the improved head-mounted infusion device divides the total amount of continuous normal infusion experienced by the infusion patient from the time of puncture to the time of needle removal within one day or 12 hours according to the infusion requirements into each container unit 7 in the head-mounted infusion container 1, so that the infusion patient can move freely during infusion. Not only does it solve the problems of overcrowding in the traditional infusion room, poor air circulation in the infusion room, and easy cross-infection between infusion patients, but it also liberates the patient's limbs, allowing the patient to freely and conveniently go to the toilet, walk, etc. For example, the patient can move to an outdoor or less crowded place for infusion, or do something easy and conducive to recovery or pass the time, such as playing a mobile phone, playing cards, and peeling melon seeds, etc.

[0040] Example two:

[0041] The head-mounted infusion device of the present application can also be an automatic head-mounted infusion device capable of remote intelligent control. The main difference between the present embodiment and the first embodiment is that the whole infusion process is automatically and intelligently controlled. As shown in Fig. 3 The head-mounted infusion container 1 of the automatic head-mounted infusion device is also composed of four annularly closed and internally hollow container units 7 stacked in layers. Each container unit 7 is provided with a liquid inlet 8 and a liquid outlet 9. The liquid inlet 8 is used to add liquid to the container unit 7. The liquid outlet 9 of each container unit 7 is connected to an infusion branch pipe 101, and the infusion branch pipes 101 are connected to an infusion main pipe 102. The end of the infusion main pipe 102 can be provided with an infusion main outlet valve 103, and the infusion main outlet valve 103 is provided with a self-sealing plug or valve. The infusion main pipe 102 is connected to the upper infusion hard pipe 2 through the infusion main outlet valve 103, that is, the head-mounted infusion container 1 can be manufactured separately from the infusion device pipeline including the upper infusion hard pipe 2, the drip bottle 3, the infusion needle 5, etc., and the two are connected during infusion. The infusion main pipe 102 can also be directly connected to the upper infusion hard pipe 2 during manufacturing, that is, the head-mounted infusion container 1 is integrally manufactured with the infusion device pipeline including the upper infusion hard pipe 2, the drip bottle 3, the infusion needle 5, etc., and is sterile packaged, and can be directly used after the package is opened and the liquid is added.

[0042] The control box 6 is also installed at the bottom of the bottommost container unit 7. The control box 6 is provided with a plurality of infusion branch pipes 101 connected to the liquid outlets of the corresponding container units 7. The infusion branch pipes 101 are provided with an air inlet pipe 104, an infusion pipe monitoring member 106, and an electromagnetic valve 107 in sequence from the position close to the liquid outlet 7. The infusion pipe monitoring member 106 is used to monitor the liquid in the infusion branch pipe 101 in real time. The infusion pipe monitoring member 106 can be an infrared photoelectric sensor, a capacitive sensor, etc. The infusion pipe monitoring member 106 and the electromagnetic valve 107 are electrically connected to the controller 12 through wired or wireless means. The infusion pipe monitoring member 106 transmits the real-time monitoring information of the liquid in the infusion branch pipe 101 to the controller 12, and the controller 12 controls the opening and closing of the electromagnetic valve 107 according to the uploaded monitoring information. The control box 6 is also provided with a control keyboard or touch screen for medical staff or patients to input corresponding parameters.

[0043] Before starting infusion, the medical staff fills the corresponding ring-shaped container monomer 7 through the liquid inlet 8, for example, a patient needs to infuse 900ml of liquid on the same day, which is liquid A (100ml), liquid B (400ml), liquid C (200ml), and liquid D (200ml), and the infusion sequence is A->B->C->D. Then, the medical staff fills the liquid as follows (usually the heavier the liquid, the lower the position when filling): liquid B is filled in the lowest ring-shaped container monomer 7 (which corresponds to the first infusion branch pipe 101), liquid C is filled in the second ring-shaped container monomer 7 from bottom to top (which corresponds to the second infusion branch pipe 101), liquid D is filled in the third ring-shaped container monomer 7 from bottom to top (which corresponds to the third infusion branch pipe 101), and liquid A is filled in the uppermost fourth ring-shaped container monomer 7 (which corresponds to the fourth infusion branch pipe 101). After filling the liquid, the medical staff inputs the corresponding parameters through the control keyboard or touch screen to control all the electromagnetic valves 107 to open, and the liquid in the corresponding ring-shaped container monomer 7 flows from the infusion branch pipe 101 to the infusion main pipe 102 until all the air bubbles in the pipe are removed. After removing the air bubbles, each infusion branch pipe 101 and the infusion main pipe 102 are filled with liquid, and the electromagnetic valve 107 on each infusion branch pipe 101 is in a closed state under the control of the controller 12. When starting infusion, the infusion pipe monitoring member 106 transmits real-time monitoring information of the liquid in the infusion branch pipe 101 to the controller 12, and when the liquid in the infusion branch pipe 101 is monitored from presence to absence and lasts for a predetermined time, the controller 12 automatically controls the electromagnetic valve 107 of the corresponding infusion branch pipe 101 to close, and simultaneously opens the electromagnetic valve 107 of the next infusion branch pipe 101. For example, if the infusion pipe monitoring member 106 monitors that the liquid in the first infusion branch pipe 101 is from presence to absence and lasts for 5 seconds or 10 seconds without monitoring the liquid, it means that the liquid B in the first infusion branch pipe 101 has been emptied from the corresponding ring-shaped container monomer 7, and the controller 12 automatically controls the electromagnetic valve 106 on the first infusion branch pipe 101 to close. At the same time, the controller 12 controls the electromagnetic valve 106 on the second infusion branch pipe 101 to open, and starts the infusion of liquid C, and so on until all the liquid is sequentially infused.

[0044] The control box 6 is also provided with a battery (not shown in the figure) for supplying power to the infusion pipe monitoring member 106, the electromagnetic valve 107, and the controller 12, which is a rechargeable battery that can be charged in wired or wireless mode. In order to minimize the weight of the head-mounted infusion container 1, the above-mentioned battery and controller 12 are generally not arranged in the control box 6, but are separately arranged in another auxiliary control box (not shown in the figure), which is electrically connected between the control box 6 and the auxiliary control box. The auxiliary control box is designed as an independent structure and can be worn on the human body, such as the shoulder or waist, through a strap, an elastic band, a magic tape, or the like.

[0045] Similarly, the inside of at least one annularly closed container unit 7 of the head-mounted infusion container 1 can be provided with a flexible membrane 11, which can have various arrangements in the inside of the container unit 7, for example, the container unit 7 is divided into two independent chambers by the flexible membrane 11, and the container unit 7 of the present embodiment is divided into two independent chambers by the flexible membrane 11, i.e., the left chamber is a liquid chamber 112 for containing liquid medicine, and the right chamber is a gas chamber 111 for filling inflatable gas, and the gas chambers 111 for filling inflatable gas in each container unit 7 are connected to each other through a pipeline (not shown in the figure). The flexible membrane 11 can have a certain elasticity or can have no elasticity at all. When not filled with liquid medicine, the flexible membrane 11 has a certain redundancy in the inside of the container unit 7. When filled with liquid medicine, under the extrusion of the liquid medicine in the liquid chamber 112, due to the certain redundancy of the flexible membrane 11, the redundancy allows the flexible membrane 11 to be completely unfolded under the extrusion of the liquid medicine to fit the upper chamber wall of the gas chamber 111, i.e., the presence of the flexible membrane 11 has little or negligible effect on the volume of the annularly closed container unit 7.

[0046] The head-mounted infusion container 1 is provided with an inflation valve 113 for inflating the gas chamber 111, which is detachably connected to an automatic inflation device 13, and the inflation valve 113 is also provided with a pressure relief valve. The automatic inflation device 13 is also provided in the above-mentioned auxiliary control box (not shown in the figure) together with the above-mentioned battery, controller 12, etc., so as not to increase the weight of the head-mounted infusion container 1. Moreover, the auxiliary control box is worn on the shoulder, waist or other parts of the human body, which is more convenient for the user to easily operate the control. The automatic inflation device 13 includes an inflation pipeline 131 for detachable connection with the inflation valve 113, a micro-inflation pump 132, and an inflation controller 133. The micro-inflation pump 132 is connected to the inflation controller 133 by wire or wireless, and the micro-inflation pump 132 and the inflation controller 133 are both connected to the above-mentioned battery. The inflation controller 133 is connected to the controller 12 by wire or wireless. The medical staff or the user can set the conditions for triggering the micro-inflation pump 132 to work, for example, when it is first monitored that there is no liquid in the infusion branch pipe 101, or when it is monitored that there is no liquid in the infusion branch pipe 101 for 3 seconds (the time), the controller 12 controls the micro-inflation pump 132 to work, and then the micro-inflation pump 132 can stop after inflating for a predetermined time, for example, 1, 2, 3 minutes, or can stop after inflating to a predetermined pressure (a pressure sensor can be provided on the end of the inflation valve 113 close to the container unit 7). And / or a corresponding drop rate sensor (such as an infrared sensor) is provided on the drip chamber 3, and the micro-inflation pump 132 can start inflation when the device monitors that the infusion drop rate of the infusion set is less than a predetermined value.
