Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a positioning projection lamp for injection. Background Technology

[0002] Referring to Chinese Utility Model Patent No. CN214713723U, which discloses an insulin injection positioning light, the light includes a lamp tube containing a bulb and a battery. An imaging plate is installed at the front end of the lamp tube, and the imaging plate has one or more positioning holes. The rear end of the lamp tube is connected to a rear cover by threads. A control switch is installed at the tail end of the rear cover. This utility model, by installing an imaging plate at the front end of the bulb on the lamp tube, allows light to form multiple illumination zones on the patient's abdomen after passing through the imaging plate, thereby achieving the effect of positioning insulin injection by means of illumination zones. In addition, the light positioning facilitates disinfection before injection and also facilitates correct insulin injection operation. Its structure is simple, easy to manufacture, and flexible to operate, and can be quickly used by medical staff or ordinary patients.

[0003] However, the aforementioned projection lamp has an imaging plate, and thus only has the function of assisting insulin injection. Its function and usage scenarios are limited and cannot meet the needs of various actual usage scenarios. Utility Model Content

[0004] The purpose of this invention is to provide an injection positioning projection lamp that combines insulin injection positioning, intramuscular injection positioning, and illumination functions, effectively solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] An injection positioning projection lamp includes a lamp tube, a bulb, and an imaging plate. A lamp head is coaxially rotatably mounted on the head of the lamp tube. Three through holes, each communicating with the inside of the lamp tube, are arranged in a circular, equidistant array around the lamp head's axis. The imaging plate is installed in one of the through holes, a positioning piece for intramuscular injection positioning is installed in another through hole, and the remaining through holes are left empty. The bulb is installed inside the lamp tube. During one rotation cycle of the lamp head, the three through holes can be sequentially aligned with the bulb.

[0007] Therefore, by arranging the imaging plate, positioning plate, and an empty through-hole in an equidistant ring array on the lamp head that is rotatably mounted on the lamp head, the three through-holes can be aligned with the bulb in sequence during one rotation cycle of the lamp head. When the imaging plate is aligned with the bulb, it can be used to assist in insulin injection. When the positioning plate is aligned with the bulb, it can be used for ordinary intramuscular or subcutaneous injection. When the empty through-hole is aligned with the bulb, the light shines out without obstruction and can be used for supplemental lighting. This lamp has multiple uses and complete functions, which can meet the needs of different usage scenarios.

[0008] Furthermore, the positioning piece is provided with a cross-shaped groove, which is through-hole.

[0009] Furthermore, a mounting partition is fixed inside the lamp tube, the bulb is mounted on the mounting partition, and a light shield is fixed around the bulb on the mounting partition. The end of the light shield is in contact with the inner surface of the lamp head, and the three through holes can be aligned with the light shield in sequence during one rotation cycle of the lamp head.

[0010] Furthermore, this positioning projection lamp also includes a protective cover that can be detachably and snapped onto the lamp head.

[0011] Furthermore, the outer wall of the lamp holder has a protrusion, on which a ring magnet is fixed. A metal ring is fixed at the end of the protective cover. When the protective cover is snapped onto the lamp holder, the metal ring magnetically engages with the ring magnet.

[0012] Furthermore, the lamp tube contains a battery for powering the bulb, and a detachable threaded cap is screwed onto the tail end of the lamp tube for removing and replacing the battery. The tail cap is equipped with a control switch for controlling the bulb.

[0013] Furthermore, a transparent plate is also provided at the front end of the lamp head.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] This invention arranges an imaging plate, a positioning plate, and an empty through-hole in an equidistant ring array on a lamp head that is rotatably mounted on the lamp head. During one rotation cycle of the lamp head, the three through-holes can be aligned with the bulb in sequence. When the imaging plate is aligned with the bulb, it can be used to assist in insulin injection. When the positioning plate is aligned with the bulb, it can be used for ordinary intramuscular or subcutaneous injection. When the empty through-hole is aligned with the bulb, the light shines out without obstruction and can be used for supplemental lighting. This multi-functional lamp can meet the needs of different usage scenarios.

[0016] This invention provides a light-shielding tube around the bulb, with the end of the tube movably fitting against the inner surface of the lamp head. During the rotation and adjustment of the lamp head, the light-shielding tube can align with the corresponding through-hole position, thereby achieving a light-shielding effect and preventing light from escaping from other positions and causing interference, thus further ensuring the accuracy of injection positioning.

[0017] This utility model, by providing an additional protective cover, can protect the imaging plate and positioning plate when the projection lamp is not in use, preventing damage from impacts and collisions. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides an injection positioning projection lamp, including a lamp tube 1, a bulb 5, and an imaging plate 22. The imaging plate 22 in this application is the same as that in the referenced patent in the background art, and the specific structure will not be described in detail. The head of the lamp tube 1 is coaxially rotatably mounted with a lamp head 2. The lamp head 2 has three through holes 21 arranged in a ring equidistant array around its axis, all of which communicate with the inside of the lamp tube 1. The imaging plate 22 is installed in one of the through holes 21, and a positioning piece 23 for intramuscular injection positioning is installed in another through hole 21. The remaining through holes 21 are left empty. The bulb 5 is installed in the lamp tube 1. During one rotation cycle of the lamp head 2, the three through holes 21 can be aligned with the bulb 5 in sequence.

[0025] An imaging plate 22, a positioning plate 23, and an empty through hole 21 are arranged in an equidistant ring array on a lamp head 2 that is rotatably mounted on the head of a lamp tube 1. During one rotation cycle of the lamp head 2, the three through holes 21 can be aligned with the bulb 5 in sequence. When the imaging plate 22 is aligned with the bulb 5, it can be used to assist in insulin injection. When the positioning plate 23 is aligned with the bulb 5, it can be used for ordinary intramuscular or subcutaneous injection. When the empty through hole 21 is aligned with the bulb 5, the light shines out without obstruction and can be used for supplemental lighting. This lamp has multiple uses and complete functions, which can meet the needs of different usage scenarios.

[0026] In addition, the rotation of lamp head 2 has a damping effect, so it will not rotate arbitrarily when not being adjusted, thus ensuring stability during positioning. The specific damping structure and principle adopt existing technology and will not be described in detail here.

[0027] Alternatively, as an option, a circular glass or acrylic plate can be embedded in the blank through hole 21. This allows light to pass through and can be used for illumination, while also preventing dust and debris from entering the lamp tube 1 and adhering to the surface of the bulb 5, thus preventing light source pollution.

[0028] Specifically, the positioning plate 23 has a cross-shaped groove 231, which is through. The light corresponding to the cross-shaped groove 231 is emitted from the cross-shaped groove 231, which can form a cross-shaped light spot projection to locate the intramuscular injection and auxiliary injection. The center of the cross-shaped light spot projection is the injection position.

[0029] Specifically, a mounting partition 11 is fixed inside the lamp tube 1, and the bulb 5 is mounted on the mounting partition 11. A light-shielding tube 6 is fixed around the bulb 5 on the mounting partition 11. The end of the light-shielding tube 6 is movably fitted with the inner surface of the lamp head 2, and during one rotation cycle of the lamp head 2, the three through holes 21 can be aligned with the light-shielding tube 6 in sequence. By setting the light-shielding tube 6 around the bulb 5, and the end of the light-shielding tube 6 is movably fitted with the inner surface of the lamp head 2, the light-shielding tube 6 can be aligned with the corresponding through hole 21 during the rotation and adjustment of the lamp head 2, thereby achieving the light-shielding effect, preventing light from shining out from other positions and causing interference, and further ensuring the accuracy of injection positioning.

[0030] Specifically, this positioning projection lamp also includes a protective cover 4, which can be detachably and snapped onto the lamp head 2. By installing the protective cover 4 on the lamp head 2, the imaging plate 22 and the positioning piece 23 can be protected when the projection lamp is not in use, so as to avoid damage from bumps and impacts.

[0031] Specifically, the lamp holder 2 has a protrusion 41 on its outer wall, and a ring magnet 42 is fixed on the protrusion 41. A metal ring 43 is fixed at the end of the protective cover 4. When the protective cover 4 is snapped onto the lamp holder 2, the metal ring 43 is magnetically attracted to the ring magnet 42. The magnetic attraction between the metal ring 43 and the ring magnet 42 enables the protective cover 4 to be detachable, making the installation and removal of the protective cover 4 convenient and quick.

[0032] Specifically, the lamp tube 1 is equipped with a battery 7 for powering the bulb 5. The tail of the lamp tube 1 is detachably threaded with a tail cover 3 for removing and replacing the battery 7. Removing the tail cover 3 makes it easy to remove and replace the battery 7. The tail cover 3 is equipped with a control switch 31 for controlling the bulb 5. By setting the control switch 31, the bulb 5 can be switched on and off.

[0033] In addition, a transparent plate 01 is provided at the front end of the lamp head 2. The transparent plate 01 can be made of transparent acrylic or glass, which can protect the imaging plate 22, the positioning plate 23 and the open lighting through hole 21.

[0034] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
