Abstract
Description
Technical Field
[0001] This utility model relates to the field of collection equipment, and more specifically, to a sputum collection device. Background Technology
[0002] Drainage bottles are widely used in hospitals. Most are ordinary drainage bottles with sputum bags inside. However, drainage bottles placed directly on the bedside table are prone to shaking. If the drainage bottle is accidentally knocked over or spilled, it can easily soil clothes or bedding, affecting the patient's hygiene. Washing clothes every time the bottle gets dirty will also add unnecessary trouble.
[0003] A search revealed that Chinese patent CN215690033U discloses a "sputum collection device," comprising a base plate, a clamping member, a first spring, and a clamping block. The clamping member is fixedly connected to the bottom of the base plate. The base plate has a groove, and the groove is vertically connected to a sliding groove. At least two sliding grooves are provided. The first spring is slidably disposed within the sliding groove, and the clamping block is slidably disposed within the sliding groove. One end of the first spring is fixedly connected to one side of the clamping block. The sputum collection assembly includes a drainage bottle, a bottle cap, a boss, a retaining plate, and a sputum bag. The drainage bottle is slidably disposed within the groove. Through the coordinated use of the base plate, clamping member, first spring, and clamping block, the possibility of the drainage bottle tipping over is effectively reduced. Simultaneously, the coordinated use of the drainage bottle, bottle cap, boss, retaining plate, and sputum bag further improves the sealing performance, reducing the possibility of sputum leakage. However, the following drawbacks still exist:
[0004] (1) The existing sputum collection device is a separate disposable box. The box body is light and easily touched, tilted and tipped over, which affects the stability of use.
[0005] (2) Existing sputum collection devices have an open structure. After collection, the sputum is always in contact with the air. The sputum will evaporate into the air and attract flying insects, causing unsanitary conditions.
[0006] Therefore, we made improvements to this and proposed a sputum collection device. Utility Model Content
[0007] The purpose of this invention is to address the problems of unstable and unhygienic use of existing sputum collection devices.
[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0009] A sputum collection device to improve the above-mentioned problems.
[0010] The present invention is as follows:
[0011] Includes a base, wherein an insertion assembly is disposed inside the base, and a closing assembly is disposed at the upper end of the insertion assembly;
[0012] The insertion assembly includes a slot inside the base, into which a collection box is detachably inserted. The collection box has inner grooves on both sides at its lower end, and an inner plate is movably disposed inside the inner grooves.
[0013] The enclosed component includes a slot inside the collection box, and a cover plate is movably disposed on the upper surface of the slot.
[0014] As a preferred technical solution of this utility model, a bottom groove is provided at the lower end of the inner groove, and a bottom plate that cooperates with the bottom groove is provided on the lower side of the inner plate.
[0015] As a preferred technical solution of this utility model, a first telescopic rod is provided on the side wall of the base plate, and a first spring is fitted on the outer wall of the first telescopic rod.
[0016] As a preferred technical solution of this utility model, the slot sidewall is provided with a slot that cooperates with the inner plate, a push plate is movably disposed inside the slot, the slot sidewall is provided with a side groove, and the push plate sidewall is provided with a side plate that cooperates with the side groove.
[0017] As a preferred technical solution of this utility model, a second telescopic rod is provided on the side wall of the side plate, and a second spring is fitted on the outer wall of the second telescopic rod.
[0018] As a preferred technical solution of this utility model, the box groove is provided with limiting grooves on both sides, and the cover plate is provided with limiting plates that cooperate with the limiting grooves on both sides.
[0019] As a preferred technical solution of this utility model, the side wall of the limiting plate is provided with a third telescopic rod, and the outer wall of the third telescopic rod is fitted with a third spring.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] In the solution of this utility model:
[0022] 1. With the collection box, inner plate, first telescopic rod, slot, and push plate, when the collection box needs to be installed, simply insert it directly downwards into the slot. The inclined surface of the inner plate is squeezed, generating a lateral force, and slides towards the inner groove, causing the bottom plate to slide within the groove. This compresses the first telescopic rod and the first spring, causing them to contract. When the inner plate aligns with the slot, the first telescopic rod and the first spring move the inner plate into the aligned slot, completing the quick installation of the collection box. When disassembly is required, push the push plate to slide the side plate within the side groove, compressing the second telescopic rod and the second spring, causing them to contract. Simultaneously, the inner plate is pushed out of the slot, completing the disassembly of the collection box. Releasing the push force allows the second telescopic rod and the second spring to push the side plate back to its original position, enabling disassembly and reuse. This improves the ease of sputum collection equipment recycling.
[0023] 2. By setting up a cover plate, a limiting plate, and a third telescopic rod, when sputum needs to be collected, manually pull the cover plate to slide it on the upper side of the box slot, causing the limiting plate to slide stably within the limiting groove. This stretches the third telescopic rod and the third spring, opening the box slot and collecting the sputum. Then, release the pull of the cover plate, and the third telescopic rod and the third spring will rebound, causing the limiting plate to enter the limiting groove, thus automatically closing the cover plate and preventing flying insects from entering, thereby improving the sealing performance of the collection device.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0034] like Figure 1-4 As shown, this embodiment proposes a sputum collection device, including a base 1, an insertion assembly is provided inside the base 1, and a sealing assembly is provided at the upper end of the insertion assembly;
[0035] The insertion assembly includes a slot 201 inside the base 1, a collection box 202 is detachably inserted into the slot 201, and inner grooves 203 are provided on both sides of the lower end of the collection box 202. An inner plate 204 is movably disposed inside the inner grooves 203.
[0036] The enclosed assembly includes a box groove 301 inside the collection box 202, and a cover plate 302 is movably disposed on the upper surface of the box groove 301.
[0037] like Figure 3 As shown, a first telescopic rod 207 is provided on the side wall of the base plate 206. A first spring 208 is fitted on the outer wall of the first telescopic rod 207. The first telescopic rod 207 and the first spring 208 are compressed to retract. When the inner plate 204 is aligned with the slot 209, the first telescopic rod 207 and the first spring 208 move the inner plate 204 to insert into the aligned slot 209, thus completing the quick installation of the collection box 202.
[0038] like Figure 3 As shown, the lower end of the inner groove 203 is provided with a bottom groove 205, and the lower side of the inner plate 204 is provided with a bottom plate 206 that cooperates with the bottom groove 205. The inclined surface of the inner plate 204 is squeezed to generate a lateral force, which slides towards the inner groove 203, causing the bottom plate 206 to slide in the bottom groove 205.
[0039] like Figure 2 As shown, the slot 201 has a slot 209 on its side wall that cooperates with the inner plate 204. A push plate 210 is movably disposed inside the slot 209. The slot 209 has a side groove 211 on its side wall. The push plate 210 has a side plate 212 on its side wall that cooperates with the side groove 211. Pushing the push plate 210 causes the side plate 212 to slide in the side groove 211, which compresses the second telescopic rod 213 and the second spring 214, causing them to retract.
[0040] like Figure 3 As shown, a second telescopic rod 213 is provided on the side wall of the side plate 212. A second spring 214 is fitted on the outer wall of the second telescopic rod 213. The second telescopic rod 213 and the second spring 214 push the side plate 212 to drive the push plate 210 to reset so that it can be disassembled and used again.
[0041] like Figure 4 As shown, a third telescopic rod 305 is provided on the side wall of the limiting plate 304. A third spring 306 is fitted on the outer wall of the third telescopic rod 305. When the third telescopic rod 305 and the third spring 306 are stretched, the box groove 301 is opened to collect sputum. Then, the tension of the cover plate 302 is released, and the third telescopic rod 305 and the third spring 306 rebound, causing the limiting plate 304 to enter the limiting groove 303, so that the cover plate 302 can be automatically closed.
[0042] like Figure 4 As shown, the box groove 301 has limiting grooves 303 on both sides, and the cover plate 302 has limiting plates 304 on both sides that cooperate with the limiting grooves 303. Manually pulling the cover plate 302 causes it to slide on the upper side of the box groove 301, which in turn causes the limiting plates 304 to slide stably within the limiting grooves 303.
[0043] Specifically, when using this collection device: When the collection box 202 needs to be installed, the collection box 202 is inserted directly downwards into the slot 201. The inclined surface of the inner plate 204 is compressed, generating a lateral force, and slides towards the inner groove 203, causing the bottom plate 206 to slide within the bottom groove 205. This compresses the first telescopic rod 207 and the first spring 208, causing them to contract. When the inner plate 204 is aligned with the slot 209, the first telescopic rod 207 and the first spring 208 move the inner plate 204 to insert into the aligned slot 209, completing the quick installation of the collection box 202. When disassembly is required, the push plate 210 is pushed, causing the side plate 212 to slide within the side groove 211. This compresses the second telescopic rod 213 and the second spring 214, causing them to contract, and simultaneously pushing the inner plate 204 out of the slot 205. The collection box 202 can be disassembled by pushing it out within 09. Releasing the push force allows the second telescopic rod 213 and the second spring 214 to push the side plate 212, causing the push plate 210 to reset, facilitating disassembly and reuse. This improves the ease of sputum collection. When sputum needs to be collected, manually pull the cover plate 302 to slide it on the upper side of the box groove 301, causing the limiting plate 304 to slide stably within the limiting groove 303. This stretches the third telescopic rod 305 and the third spring 306, opening the box groove 301 for sputum collection. Then, releasing the pull force on the cover plate 302 causes the third telescopic rod 305 and the third spring 306 to rebound, pushing the limiting plate 304 into the limiting groove 303, automatically closing the cover plate 302 and preventing insects from entering, thus improving the sealing of the collection device.
[0044] All technical features in this embodiment can be freely combined according to actual needs.
[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
