[0031] As described above, after using the equipment related to the spray of the medicine, it is often necessary to clean and disinfect the spray device. In this process, it is relatively complicated to disassemble the spray device. Cleaning also consumes a long time and costs a lot.

[0032] In order to at least partially solve one or more of the above problems and other potential problems, the exemplary embodiments of the present disclosure propose a spray device solution. In the disclosed solution, through the electrical connection unit provided on the housing, electrical energy can be obtained from the outside to provide a driving electrical signal to the spray unit, so that the spray device can be easily docked or separated from the operating instrument, thereby facilitating the processing of the spray device (for example, removing and discarding the spray unit therein, and disinfecting the housing).

For the convenience of explanation, the positive directions of the X-axis, the Y-axis and the Z-axis are indicated by arrows. Figure 2 A schematic side view of a spray device 100 according to an embodiment of the present disclosure is shown. Figure 3 The top view of the spray device 100 according to the embodiment of the present disclosure is shown. In order to facilitate the display of the internal structure, the top of the housing is hidden and not shown. Figure 4 A cross-sectional schematic diagram of a spray device 100 according to an embodiment of the present disclosure is shown. Figure 5 A perspective schematic diagram of the spray unit 104 according to an embodiment of the present disclosure is shown.

[0034] The spray device 100 includes a housing 102 and a spray unit 104. The housing 102 is configured to accommodate at least part of the spray unit 104. An electrical connection unit 108 is provided on the housing 102. The electrical connection unit 108 is configured to obtain electrical energy from the outside so as to provide a driving electrical signal to the spray unit 104. For example, the housing 102 forms a second accommodating cavity 106. The housing 102 is provided with an electrical connection unit 108 electrically connected to the spray unit 104. The electrical connection unit 108 is used to obtain electrical energy from the outside so as to provide a driving electrical signal to the spray unit 104. For example, the electrical connection unit 108 can be connected to an external power line 202 so as to provide electrical energy to the spray unit 104. The electrical connection unit 108 is, for example, a socket.

[0035] The spray unit 104 is disposed in the housing 102. For example, the spray unit 104 is disposed in the second accommodating chamber 106. The spray unit includes a liquid storage unit 142, a spray needle 146 and a driving unit 148.

[0036] The liquid storage unit 142 is used to store the liquid to be atomized. One end of the spray needle 146 is connected to the liquid storage unit 142 for circulating the liquid to be atomized, and the other end of the spray needle (for example, the needle tip of the spray needle) extends to the outside of the housing 102. The drive unit 148 is connected to the spray needle 146 and is used to drive the spray needle 146 under the control of the drive electrical signal so that the liquid to be atomized is sprayed from the spray needle 146. The drive unit 148 is, for example, disposed on one side of the spray needle 146 so as to drive the spray needle 146 under the control of the drive electrical signal. The liquid to be atomized is, for example, a medical liquid.

[0037] The liquid storage unit 142 includes, for example, a receiving portion 1422. The receiving portion 1422 includes a first receiving chamber for storing the liquid to be atomized, and one end of the first receiving chamber is communicated with the spray needle 146.

[0038] The liquid storage unit further includes a sealing portion 1424. The sealing portion 1424 is used to seal the other end of the first accommodating chamber 1422, and the sealing portion 1424 is configured to be removed under the action of an external force so as to release the sealing of the first accommodating chamber 1424.

[0039] In some embodiments, the first accommodating chamber 1422 of the liquid storage unit 142 of the spray device 100 pre-stores the liquid to be atomized. The liquid to be atomized is, for example, a pharmaceutical liquid for treatment. The spray device 100 can, for example, spray the liquid to be atomized onto the surface of the affected area or the surface of the treatment device. Among them, the sealing portion 1424 seals the first accommodating chamber 1422 to prevent the liquid to be atomized in the liquid storage unit 142 from flowing out or being contaminated. In some embodiments, a removable protective cover is provided at the needle tip of the spray needle 146. The protective cover can prevent the liquid to be atomized in the liquid storage unit 142 from flowing out or being contaminated, and can also protect the needle tip of the spray needle from being damaged or from being contaminated. Before use, the protective cover can be removed so that the needle tip of the spray needle 146 is connected to the outside. In addition, the sealing portion 1424 can be removed so that the sealing state of the first accommodating chamber 142 is released, thereby facilitating the liquid to be atomized to be sprayed out.

[0040] In some embodiments, the sealing portion 1424 is a sealing film that can be destroyed or torn off by external force and thus removed.

[0041] In some embodiments, the sealing portion 1424 is a sealing cover that can be removed by external force.

[0042] It is worth noting that the housing 102 includes a main body 1202 and a cover 1024. The main body 1202 and the cover 1204 cooperate to form a second accommodating chamber 106. The second accommodating chamber 106 is used to accommodate at least part of the spray unit. When the cover 1024 is opened, at least part of the liquid storage unit 142 is exposed. For example, when the cover 1024 is opened, the sealing portion 1424 of the liquid storage unit 142 is exposed so that the operator can remove the sealing portion 1424.

[0043] In some embodiments, a vent hole is provided on the shell 102 , and the vent hole passes through the shell 102 , so that the first accommodating cavity 1422 after the sealing portion 1424 is removed is connected to the outside, for example, connected to the atmosphere.

[0044] In some embodiments, the main body 1202 and the cover 1024 are snap-fitted to facilitate separation of the cover 1024 from the main body 1202 so as to open the cover 1024. For example, after the cover 1024 is separated from the main body 1202, the entirety of the liquid storage unit 142 can be exposed.

[0045] In some embodiments, the cross-sectional size of one end of the first accommodating chamber is smaller than the cross-sectional size of the other end of the first accommodating chamber. For example, the first accommodating chamber is conical, that is, the accommodating portion surrounds a conical space as the first accommodating chamber. Based on the shape of the first accommodating chamber, it is convenient for the liquid to be atomized to be sprayed out. In addition, when the height of the liquid to be atomized remaining in the liquid storage unit 142 is low, based on the natural flow resistance of the spray needle 146, when the liquid to be atomized is difficult to be sprayed out, the spraying can be stopped. In view of the small size of one end of the first accommodating chamber (that is, the end connected to the spray needle 146), the amount of liquid to be atomized that is difficult to be sprayed out that remains in the liquid storage unit 142 is also very small, which can save the liquid to be atomized and reduce waste.

[0046] The liquid storage unit 142, for example, further includes a bending portion 1248, which is disposed at one end of the first accommodating chamber. The liquid storage unit 142 is connected to the spray needle 147 through the bending portion 1248. The bending portion 1248 is, for example, an L-shaped bending portion. The bending portion 1248 is, for example, bent at a right angle. On the one hand, the flow resistance of the liquid to be atomized can be effectively controlled by the bending portion 1248. On the other hand, the direction in which the spray needle 146 extends can also be easily set. For example, Figure 4 In the arrangement shown, the spray needle 146 extends in the horizontal direction, and the liquid storage unit 142 is higher than the spray needle 146. At this time, the liquid to be atomized can have a tendency to flow from the liquid storage unit 142 to the spray needle 146 by gravity.

[0047] In some embodiments, the liquid storage unit 142 further includes a liquid injection portion 1426. The liquid injection portion 1426 is disposed at the other end of the first accommodating chamber, and is configured so that the liquid to be atomized is injected into the first accommodating chamber via the liquid injection portion 1426. The liquid storage unit 142, for example, includes an end cap portion 1428, which is disposed at the other end of the first accommodating chamber, and a channel is formed in the end cap portion 1428 as the liquid injection portion 1426. The injection device (e.g., a syringe) can inject the liquid to be atomized into the first accommodating chamber via the liquid injection portion 1426 through the liquid injection portion 1426. When the liquid storage unit 142 is provided with a sealing portion 1424, the sealing portion 1424 can be removed first, and then the liquid is injected. For example, the injection device (e.g., a syringe) can pierce the sealing portion 1424 (e.g., a sealing film) to inject the liquid.

[0048] It is worth noting that the housing 102 of the spray device 100 is also provided with a fixing portion for fixing the spray device 100 to the target device. The fixing portion is, for example, a fixing screw hole, through which the spray device 100 can be fixed to the target device. The target device is, for example, a stent or a device for performing a treatment operation.

[0049] In addition, a clamping structure 1206 is provided on the inner surface of the housing 102. A clamped portion 1230 is provided on the outer surface of the spray unit 104. When the spray unit 104 is installed in the second accommodating chamber 106 of the housing 102, the clamped portion 1230 of the spray unit 104 cooperates with the clamping structure 1206 of the housing 102, and the clamping structure 1206 clamps the clamped portion 1230, so as to fix the spray unit 104 in the second accommodating chamber 106 of the housing 102. The clamping structure 1206 is, for example, two clamping arms arranged opposite to each other, and when the spray unit 104 is installed in the second accommodating chamber 106 of the housing 102, the two clamping arms arranged opposite to each other clamp the spray unit 104. For example, a clamped portion 1230 is provided on each side of the spray unit 104, and the clamped portion 1230 is provided with a groove, and the clamping portion of the clamping arm can be clamped into the groove, so as to strengthen the fixation of the spray unit 104. The two clamping arms are, for example, elastic arms.

[0050] The driving unit 148 includes, for example, a metal plate 1482 and a piezoelectric material unit (not shown in the figure). The edge of the metal plate 1482 is connected to the spray needle 146. The piezoelectric material unit is disposed on a first side of the metal plate 1482 and is electrically connected to the electrical connection unit 108, and is used to drive the metal plate 1482 to move under the control of the driving electrical signal, so that the liquid to be atomized is sprayed from the spray needle 146.

[0051] It is worth noting that the clamped portion 1230 and the two clamping arms of the spray unit 104 are conductors, the two clamping arms are configured to be electrically connected to the electrical connection unit 108, and the clamped portion of the spray unit 104 is configured to be electrically connected to the driving unit 148, so that the electrical connection unit 108 provides a driving electrical signal to the spray unit 104 via the clamped portion 1230 and the two clamping arms. For example, there are two clamped portions 1230 of the spray unit 104, which are respectively arranged on both sides of the spray unit 104 to correspond to the two clamping arms. The two clamped portions 1230 are electrically connected to the positive electrode and the negative electrode of the driving unit 148, respectively, and the two clamping arms are electrically connected to the positive electrode and the negative electrode of the electrical connection unit 108, respectively. When the spray unit 104 is installed in the second accommodating cavity 106 of the housing 102, the clamped portion 1230 of the spray unit 104 cooperates with the clamping structure 1206 of the housing 102, and the clamping structure 1206 clamps the clamped portion 1230, so as to fix the spray unit 104 in the second accommodating cavity 106 of the housing 102. In addition, the drive unit 148 can be electrically connected to the electrical connection unit 108 through the clamped portion 1230 and the clamping arm, so as to obtain electrical energy from the electrical connection unit 108.

[0052] In some embodiments, the spray device 100 further includes an air knife 110. The air knife 110 is disposed on the housing 102, and the air outlet of the air knife 110 faces the tip of the spray needle 146. In some embodiments, the spray device 100 may not be provided with an air knife.

[0053] It is worth noting that the spray unit 104 is, for example, a disposable spray unit 104. For example, after the spray operation is completed, the housing 102 can be opened and the spray unit 104 can be taken out. The spray unit 104 can be discarded or recycled. The housing 102 can be sterilized for reuse. For example, the housing 102 can be sterilized using sterilizing rays.

[0054] Figure 6 The schematic diagram of the spray device 300 of the embodiment of the present disclosure is shown. The liquid storage unit 142 is a syringe. For example, the housing 102 can be opened, the syringe storing the liquid to be atomized can be docked with the spray needle 146, and then the drive unit 148 can be started to implement the spraying operation. The syringe can be docked with the spray needle 146 through the conduit 150, for example.

[0055] Figure 7 The cross-sectional schematic diagram of the spray device 200 of the embodiment of the present disclosure is shown, wherein the first accommodating cavity of the accommodating portion 1422 is cylindrical, the portion of the bent portion 1248 communicating with the first accommodating cavity of the accommodating portion 1422 is hemispherical, and the portion of the bent portion 1248 communicating with the spray needle 146 is linear.
