Description

Technical Field

[0001] The invention relates to the field of medical technology, and in particular to a novel head-mounted infusion device. Background Art

[0002] During intravenous infusion, the liquid medicine that the patient needs to infuse on the same day is usually prepared at one time and packaged in multiple infusion bags / bottles and hung on the hook of the infusion stand. After one bottle / bag of liquid medicine is infused, the patient usually notifies the medical staff to replace it before the next bottle / bag of liquid medicine is infused, which increases the burden on medical staff. In addition, since the infusion bottle or infusion bag needs to be supported by the infusion stand, it is inconvenient for the patient to walk, go to the toilet and other activities. At the same time, during the existing intravenous infusion, close contact is formed between multiple patients in the same infusion room, and cross-infection is prone to occur between multiple patients, thereby increasing the risk of disease transmission. In addition, when multiple patients receive infusion treatment in a fixed space at the same time, it is also easy to cause problems such as noise and crowding, which brings discomfort and psychological pressure to patients and may increase the recovery time of patients.

[0003] There are some wearable or movable infusion devices in the prior art, which allow patients to move relatively freely without holding an infusion bottle or bag. For example, head-worn infusion devices, but head-worn infusion devices in the prior art can only carry one bottle / bag of liquid medicine, and do not fundamentally solve the technical problems of free movement, freeing hands, and reducing fluid changes during infusion, which is not friendly to both patients and medical staff.

[0004] In addition, the infusion container of the head-mounted infusion device is usually worn on the patient's head. Compared with the support height of the traditional infusion stand for the infusion bag, the support height of the head-mounted infusion container is low, and the gravitational potential energy obtained is smaller than that of the infusion bag supported by the traditional infusion stand. Therefore, in the second half of the infusion, especially when the infusion of the medicine is about to end, the collapse of the infusion container may cause wrinkles or unevenness inside, which may cause the remaining medicine to accumulate at the bottom of the infusion container, resulting in insufficient flow kinetic energy, resulting in a decrease in the infusion flow rate or even stagnation. In addition, the retention of medicine in the collapsed infusion container also causes a waste of medicine, which is not conducive to disease treatment.

[0005] In view of this, it is necessary to develop a new head-mounted infusion device to solve the above problems. Summary of the invention

[0006] In view of this, an object of the present invention is to provide a novel head-mounted infusion device.

[0028] The technical solution of the present invention will be clearly and completely described below through specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See attached Figures 1 to 3 As shown, a new head-mounted infusion device of the present application includes a head-mounted infusion container 1, an upper infusion hard tube 2, a drip pot 3, a lower infusion hose 4 and an infusion needle 5 connected in sequence from top to bottom. The head-mounted infusion container 1 includes a control box 6 and a plurality of annular container monomers 7 with hollow interiors. Each container monomer 7 is stacked, and the control box 6 is installed at the bottom of the container monomer 7 of the bottom layer. A drug liquid inlet 8 and a drug liquid outlet 9 are provided on each container monomer 7. Each drug liquid outlet 9 is connected to an infusion tube, which extends into the control box 6. The infusion tube extends from the control box 6 after being regulated by the control box 6, and the infusion tube is connected with the upper infusion hard tube 2 at the end extending from the control box 6.

[0030] Embodiment 1:

[0031] See attached Figure 1 and attached Figure 2As shown, the head-mounted infusion container 1 of the present application is composed of four annular container monomers 7 with hollow interiors stacked up and down. The shape formed by the stacking of the four container monomers 7 can be stably worn on the head of the infusion patient or the caregiver, that is, the size and shape of the head-mounted infusion container 1 are suitable for wearing on the head of the infusion patient or the caregiver, and in order to fit the head size of different people, the overall interior of the head-mounted infusion container 1 is hollow, and can be formed into, for example, a cylindrical, truncated cone, a conical or similar shape, such as a hat shape. The four container monomers 7 are all annularly closed, and their interiors are hollow. The four container monomers 7 are all provided with a liquid medicine inlet 8 and a liquid medicine outlet 9. The liquid medicine inlet 8 is used to add liquid medicine to the annularly closed container monomer 7. The liquid medicine inlet 8 is provided with a self-sealing first sealing member, that is, a sealing plug or a sealing valve. The liquid medicine outlet 9 includes a sinking portion with a gradually smooth slope from the inner wall of the lowest part of the annularly closed container monomer 7, thereby forming a low point similar to a funnel, so that the liquid medicine in the annularly closed container monomer 6 can be gathered with the sinking portion as the center.

[0032] Clinically, the total amount of normal infusion experienced by adult infusion patients from acupuncture to needle removal within one day or within 12 hours is generally less than 2500ml, usually in the range of 800ml to 2000ml, and most of them are usually around 1000ml to 1500ml. Therefore, the specific number of head-mounted infusion containers 1 is preferably composed of 2 to 8 annular closed container monomers 7, and more preferably 2 to 6 annular closed container monomers 7. The volume of a single annular closed container monomer 7 is set to be between 100ml and 600ml, for example, 100ml, 150ml, 200ml, 225ml, 250ml, 300ml, 325ml, 350ml, 400ml, 425ml, 450ml, 500ml, 550ml, 600ml, etc. For a complete head-mounted infusion container 1, the volume of each annular closed container monomer 7 can be the same, different, or only partially the same. The total volume range of the head-mounted infusion container of the present application is preferably between 600ml and 2600ml, and more preferably between 800ml and 2200ml.

[0033] In the present application, each liquid medicine outlet 9 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 from the control box 6, and the end of the infusion tube extending from the control box 6 is connected to the upper infusion hard tube 2. The infusion tube includes an infusion branch tube 101 and an infusion main tube 102, one end of each infusion branch tube 101 is respectively connected to each liquid medicine outlet 9 on each container monomer 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, and the liquid medicine in each container monomer 7 flows from each infusion branch tube 101 into the infusion main tube 102, and the liquid medicine output end of the infusion main tube 102 is connected in series with the upper infusion hard tube 2. The upper end of the upper infusion rigid tube 2 is connected to the infusion main pipe 102 extending from the control box 6 of the head-mounted infusion container 1, or is directly connected to the medicine liquid outlet 8 of the container monomer 7 of the head-mounted infusion container 1, and the lower end of the upper infusion rigid tube 2 is connected to the drip pot 3.

[0034] Regarding the drip pot 3, in order to seek a suitable balance between the flow of the drug solution and the prevention of blood return, the drip pot 3 should have a suitable and reasonable height. In the present application, the lower limit of the height of the drip pot 3 ("the height of the drip pot" can be defined as the height of the uppermost end (or the lowermost end) of the drip pot 3 relative to the ground, or the height of the center of the drip pot 3 relative to the ground) is not lower than the height of the human heart, or not lower than the height of the acupuncture position of the patient's arm when standing, and the upper limit of the height of the drip pot 3 is not higher than the height of the human shoulder, or not higher than the center height of the human neck. In the present application, the height of the drip pot 3 is preferably set between the height of the human heart and the height of the human shoulder.

[0035] The upper infusion hard tube 2 of the present application is made of a hard material, such as hard plastic, metal, etc. Figure 1 As shown, the upper infusion rigid tube 2 includes a curved section that tilts downward when worn and a vertical section connected to the drip pot 3. The upper infusion rigid tube 2 with such a structural design can vertically suspend the drip pot 3 to facilitate the dripping of the infusion liquid from the drip pot 3. At the same time, the rigid upper infusion rigid tube 2 is also easy to shape. For example, the rigid upper infusion rigid tube 2 can be set to extend roughly parallel to the direction of the human shoulder. In this way, the drip pot 3 and the lower infusion hose 4 connected to the rigid upper infusion rigid tube 2 will not hinder the infusion patient's line of sight, nor will they hinder the infusion patient's two-handed operation. Therefore, in this application, Figure 1 As shown, the hard upper infusion tube 2 is tilted downward relative to the head-mounted infusion container 1, and extends parallel to the human shoulder when worn. The projection distance of the upper infusion tube 2 along the human shoulder is set not to exceed the width of one shoulder of the human body.

[0036] Since the liquid medicine outlet 9 of each container monomer 7 of the present application is connected to the main infusion pipe 102 through the infusion branch pipe 101, the end of the main infusion pipe 102 can be provided with an infusion main outlet valve 103, and the main infusion outlet valve 103 is provided with a second sealing member that can be self-sealed, that is, a sealing plug or a sealing valve. The main infusion pipe 102 is connected to the upper infusion hard tube 2 through the main infusion 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 tube 2, the drip pot 3, the infusion needle 5, etc., and the two are connected during infusion. The main infusion pipe 103 can also be directly connected to the upper infusion hard tube 2 during manufacturing, that is, the head-mounted infusion container 1 and the infusion device pipeline including the upper infusion hard tube 2, the drip pot 3, the infusion needle 5, etc. are manufactured as a whole and aseptically packaged, and the package is directly opened to add liquid medicine for infusion when used.

[0037] The control box 6 is installed at the bottom of the container monomer 7 at the bottom layer. Part of the tube body of each infusion branch pipe 101 and the infusion main pipe 102 are arranged in the control box 6. An air intake pipe 104 is arranged near the medicine outlet 7 on each infusion branch pipe 101. Each infusion branch pipe 101 is also provided with a first speed regulating device 105 for flow cutoff and / or flow rate control. The infusion branch pipe 101, the first speed regulating device 105 and the infusion main pipe 102 are all integrated on the control box 6 to control the infusion of each container monomer 7. The infusion main pipe 102 is connected to the lower infusion hose 4. The end of the lower infusion hose 4 is connected to the infusion needle 5. The lower infusion hose 4 is also provided with a second speed regulating device 41, a filter 42 and other components. The control box 6 may include a box body and a cover body (not shown in the figure) hinged to the box body. Medical staff or infusion patients can open the cover body to control the first speed regulating device 105, thereby adjusting the infusion flow rate of the corresponding infusion branch 101 or shutting down the corresponding infusion branch 101. After setting, the cover body can be closed, and the cover body protects and prevents dust from the various components in the box body.

[0038] See attached Figure 2As shown, at least one annular closed container monomer 7 of the head-mounted infusion container 1 is provided with a flexible membrane 11 inside, and the flexible membrane 11 divides the internal cavity of the container monomer 7 into a gas chamber 111 and a liquid medicine chamber 112, and the container monomer 7 of this embodiment is divided into two independent upper and lower chambers by the flexible membrane 1, that is, the lower chamber is a liquid medicine chamber 112 for containing liquid medicine, and the upper chamber is a gas chamber 111 for filling inflatable gas. The flexible membrane 11 can have a certain elasticity or no elasticity at all. When the liquid medicine is not filled, the flexible membrane 11 has a certain redundancy inside the container monomer 7; when the liquid medicine is filled, under the pressure of the liquid medicine in the liquid medicine chamber 112, due to the redundancy of the flexible membrane 11, the redundancy enables the flexible membrane 11 to be fully expanded under the pressure of the liquid medicine to fit the upper cavity wall of the gas chamber 111, that is, the existence of the flexible membrane 11 will hardly affect the volume of the container monomer 7, or the effect is so small that it can be ignored.

[0039] In addition, each gas chamber 111 in each container monomer 7 is interconnected through a pipeline (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 interconnected, only one inflation valve 113 is needed to inflate all the connected gas chambers 111. The inflation valve 113 is detachably connected to a manually pressable inflatable airbag 114. In the middle and late stages of infusion, if the dripping rate is slow, or the infusion is near the end, the infusion container monomer 7 will collapse after the liquid medicine is reduced, causing part of the liquid medicine to accumulate in the folds of the collapsed container monomer 7 and cannot flow normally. At this time, the patient or the accompanying person can manually press the inflation airbag 114 to inflate the gas chamber 111 of the container monomer. On the one hand, this can inflate the collapsed container monomer 7, and the inner wall of the container monomer 7 becomes smooth, which is conducive to the flow of liquid medicine. On the other hand, manual inflation can increase the internal pressure of the container monomer 7 and promote the flow of the medicine to the outlet. In addition, although the gas chambers 111 of each container monomer 7 are interconnected, when the gas is inflated through the inflation valve 113, only the collapsed container monomer 7 will be squeezed and inflated. For the container monomer 7 that has not yet been infused with medicine, since the medicine outlet 9 of the container monomer 7 is not opened, it will not be affected when inflated. A pressure relief valve is also provided on the inflation valve 113. The head-mounted infusion container 1 of the present application is placed on the head of the infusion patient or the infusion companion during infusion. The overall height of the head-mounted infusion container 1 is lower than the height of the infusion bottle / bag supported by the infusion stand for traditional infusion. By providing the inflation valve 113 and the inflation airbag 114, on the one hand, the pressure of the collapsed container is increased, thereby increasing the kinetic energy of the medicine, and on the other hand, the inner wall of the collapsed container becomes smooth after inflation, which is also conducive to the flow of medicine. It can make up for the defects of the head-mounted infusion container 1, such as the small dynamic potential energy of the infusion bag supported by the traditional infusion stand, the easy accumulation of residual liquid medicine and the slow infusion flow rate. At the same time, compared with the traditional infusion in which the infusion liquid medicine is contained in the infusion bottle / bag, the improved head-mounted infusion device can pack the total amount of normal infusion experienced by the infusion patient from the time of acupuncture to the time of needle removal within one day or within 12 hours into each container monomer 7 in the head-mounted infusion container 1 according to the infusion requirements, so that the infusion patient can move freely during the infusion. It not only solves the disadvantages of crowded personnel in the traditional infusion room, poor air circulation in the infusion room, and easy cross infection between infusion patients, but also liberates the patient's limbs, so that the patient can go to the toilet and walk freely and conveniently, for example, he can move to the outdoors or a place where there are no crowds of people for infusion, or do some relaxing things that are conducive to recovery or kill boring time while infusing, such as playing with mobile phones, playing cards, peeling melon seeds, etc.

[0040] Embodiment 2:

[0041] The head-mounted infusion device of the present application may also be an automatic head-mounted infusion device capable of remote intelligent control. The main difference between this embodiment and the first embodiment is that the entire infusion process is automatically and intelligently controlled. Figure 3 As shown, the head-mounted infusion container 1 of the automatic head-mounted infusion device is also composed of four annular closed and hollow container monomers 7 stacked up and down. Each container monomer 7 is provided with a liquid medicine inlet 8 and a liquid medicine outlet 9. The liquid medicine inlet 8 is used to add liquid medicine to the container monomer 7. The liquid medicine outlet 9 of each container monomer 7 is connected to the main infusion pipe 102 through an infusion branch pipe 101. The end of the main infusion pipe 102 can be provided with an infusion main outlet valve 103, and the main infusion outlet valve 103 is provided with a self-sealing sealing plug or sealing valve. The main infusion pipe 102 is connected to the upper infusion hard tube 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 tube 2, the drip pot 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 tube 2 during manufacturing, that is, the head-mounted infusion container 1 and the infusion device pipeline including the upper infusion tube 2, the drip pot 3, the infusion needle 5, etc. are manufactured integrally and sterilely packaged. When in use, the package can be opened directly to add the medicine and then the infusion can be carried out.

[0042] The control box 6 is also installed at the bottom of the bottom container monomer 7. A plurality of infusion branches 101 connected to the liquid outlets of the corresponding container monomers 7 are arranged in the control box 6. An air intake pipe 104, an infusion tube monitoring component 106 and a solenoid valve 107 are arranged on each infusion branch 101 from the position close to the liquid outlet 7 downward in sequence. The infusion tube monitoring component 106 is used to monitor the presence of liquid in the infusion branch 101 in real time. The infusion tube monitoring component 106 can be an infrared photoelectric sensor, a capacitive sensor, etc. The infusion tube monitoring component 106 and the solenoid valve 107 are electrically connected to the controller 12 by wire or wireless means. The infusion tube monitoring component 106 transmits the real-time monitoring information of the liquid in the infusion branch 101 to the controller 12, and the controller 12 controls the opening and closing of the solenoid 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 the infusion, the medical staff fills the corresponding annular container monomers 7 with liquid medicine through the liquid medicine inlet 8. For example, a patient needs to infuse 900 ml of liquid medicine once a day, which are liquid medicine A (100 ml), liquid medicine B (400 ml), liquid medicine C (200 ml), and liquid medicine D (200 ml). The infusion order is A->B->C->D. Then, when the medical staff fills the liquid medicine, the situation is as follows (usually the heavier the liquid medicine is, the lower it is when it is filled): liquid medicine B is filled in the lowest annular container monomer 7 (which corresponds to the first infusion branch 101), liquid medicine C is filled in the second annular container monomer 7 from the bottom to the top (which corresponds to the second infusion branch 101), liquid medicine D is filled in the third annular container monomer 7 from the bottom to the top (which corresponds to the third infusion branch 101), and liquid medicine A is filled in the fourth annular container monomer 7 at the top (which corresponds to the fourth infusion branch 101). After the liquid medicine is filled, the medical staff inputs the corresponding parameters through the control keyboard or touch screen to control all the solenoid valves 107 to open, and the liquid medicine in the corresponding annular container monomer 7 flows from each infusion branch 101 to the infusion main pipe 102 until all bubbles in the pipe are removed. After the bubbles are removed, each infusion branch 101 and the infusion main pipe 102 are filled with liquid, and the solenoid valve 107 on each infusion branch 101 is closed under the control of the controller 12. When the infusion starts, the infusion tube monitoring component 106 transmits the real-time monitoring information of the liquid in the infusion branch 101 to the controller 12. When it is monitored that the liquid in the infusion branch 101 changes from presence to absence and lasts for a predetermined period of time, the controller 12 automatically controls the solenoid valve 107 of the corresponding infusion branch 101 to close, and opens the solenoid valve 107 of the next infusion branch 101 at the same time. For example, if the infusion tube monitoring component 106 detects that the liquid in the first infusion branch 101 disappears from the liquid and continues to detect no liquid for 5 seconds or 10 seconds, it means that the liquid medicine B in the first infusion branch 101 may have been emptied from the corresponding annular container monomer 7, and the controller 12 automatically controls the electromagnetic valve 106 on the first infusion branch 101 to close. At the same time, the controller 12 controls the electromagnetic valve 106 on the second infusion branch 101 to open, and starts the infusion of liquid medicine C, and so on, until all liquid medicines are infused in sequence.

[0044] The control box 6 is also provided with a battery (not shown in the figure) for powering the infusion tube monitoring component 106, the solenoid valve 107 and the controller 12. The battery is a rechargeable battery that can be charged by wire or wirelessly. In order to reduce the weight of the head-mounted infusion container 1 as much as possible, the above-mentioned battery and the 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). The auxiliary control box is electrically connected to the control box 6. The auxiliary control box is designed as an independent structure and can be worn on the shoulders, waist and other parts of the human body by a lace, an elastic band, a Velcro strap, etc.

[0045] Similarly, at least one annular closed container monomer 7 of the head-mounted infusion container 1 may be provided with a flexible membrane 11 inside. The flexible membrane 11 may be arranged in a variety of ways inside the container monomer 7. For example, the container monomer 7 is divided into two independent chambers, upper and lower or left and right, by the flexible membrane 11. The container monomer 7 of this embodiment is divided into two independent chambers, left and right, by the flexible membrane 1, that is, 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 monomer 7 are interconnected through pipes (not shown in the figure). The flexible membrane 11 may have a certain elasticity or may not have elasticity at all. When not filled with liquid medicine, the flexible membrane 11 has a certain amount of redundancy inside the container monomer 7. When filling with liquid medicine, under the squeezing of the liquid medicine in the liquid medicine chamber 112, since the flexible membrane 11 has a certain redundancy, the flexible membrane 11 can be fully expanded under the squeezing of the liquid medicine until it can fit against the upper cavity wall of the gas chamber 111, that is, the existence of the flexible membrane 11 will hardly affect the volume of the annular closed container monomer 7, or the impact is so small that it can be ignored.

[0046] The head-mounted infusion container 1 is provided with an inflating valve 113 for inflating the gas chamber 111, and the inflating valve 113 is detachably connected to the automatic inflating device 13, and a pressure relief valve is also provided on the inflating valve 113. The automatic inflating device 13 is also arranged in the auxiliary control box (not shown in the figure) together with the above-mentioned battery, controller 12, etc., in order not to increase the weight of the head-mounted infusion container 1. Moreover, the auxiliary control box is worn on the shoulders, waist and other parts of the human body, which makes it easier for the user to operate and control. The automatic inflating device 13 includes an inflating pipeline 131, a micro-inflating pump 132, and an inflating controller 133 for detachably connecting to the inflating valve 113. The micro-inflating pump 132 is connected to the inflating controller 133 by wire or radio, and the micro-inflating pump 132 and the inflating controller 133 are both electrically connected to the above-mentioned battery. The inflating controller 133 is connected to the controller 12 by wire or radio. Medical personnel or users can set corresponding conditions for triggering the operation of the micro-pump 132: for example, when it is first detected that there is no liquid in the infusion branch 101, or when it is detected that there is no liquid in the infusion branch 101 for 3 consecutive seconds (this time), the controller 12 controls the micro-pump 132 to work, and then the micro-pump 132 can stop after inflating at a predetermined rate for a predetermined time, such as 1, 2, or 3 minutes, or it can stop after the micro-pump 132 is inflated to a predetermined pressure (a pressure sensor can be set at one end of the inflation valve 113 close to the container monomer 7). And / or a corresponding dripping rate sensor (such as an infrared sensor) is set on the drip pot 3, and the micro-pump 132 can start inflation when the device detects that the infusion dripping rate of the infusion device is less than a predetermined value.

[0047] The automatic head-mounted infusion device also includes a wireless transmission module. The data information monitored by the head-mounted infusion device, including but not limited to the information on the presence or absence of liquid in the infusion branch 101, inflation pressure monitoring, infusion start or completion information, infusion drip rate information, etc., can be synchronously uploaded to at least one of the terminal server, cloud server or hospital HIS system, and the doctor or nurse can view the above corresponding infusion information in real time on a mobile phone, computer, PAD or other medical terminal connected to at least one of the terminal server, cloud server or hospital HIS system. At the same time, the doctor or nurse can also send corresponding control instructions to the automatic head-mounted infusion device through the above mobile phone, computer, PAD or other medical terminals, including but not limited to handling abnormal infusion conditions (for example, terminating abnormal infusion by controlling the solenoid valve), adjusting infusion parameters (for example, adjusting the drip rate of a certain drug solution), etc.

[0048] The automatic head-mounted infusion device can automatically realize intelligent control of the entire infusion process, such as parameter setting, infusion start, exception handling, infusion situation monitoring (such as drip rate monitoring, etc.), and infusion end, based on the group big data information stored in at least one of the terminal server, cloud server or hospital HIS system during the entire infusion process, by the corresponding artificial intelligence program. That is, a continuous normal infusion process experienced by the infused patient from needle insertion to needle removal within a day or 12 hours basically does not require the patient to participate in the management, which reduces the infusion burden on medical staff, infused patients and accompanying family members.
